Business and Principles of Consolidation [Abstract]
Business and Principles of Consolidation	Business and Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of Essex Rental Corp. (“Essex Rental”) and its wholly owned subsidiaries Essex Holdings, LLC ("Holdings"), Essex Crane Rental Corp. ("Essex Crane"), Essex Finance Corp. (“Essex Finance”), CC Acquisition Holding Corp. (“CC Acquisition”), Coast Crane Company, formerly known as CC Bidding Corp. (“Coast Crane”) and Coast Crane Ltd. (“Coast Crane Ltd.) (collectively the "Company"). All intercompany accounts and transactions have been eliminated in consolidation.
	The Company is engaged primarily in renting lattice boom crawler cranes and attachments, tower cranes and attachments, rough terrain cranes, boom trucks and other related heavy lifting machinery and equipment to the construction industry throughout the United States of America, including Hawaii and Alaska, and Canada. The assets are rented for use in building and maintaining power plants, refineries, bridge and road construction, alternative energy, water treatment facilities and other industrial, commercial, residential and infrastructure related projects. The Company is also engaged in servicing and distributing heavy lifting machinery and other construction related equipment and parts.
	The accompanying consolidated financial statements of the Company include all adjustments (consisting of normal recurring adjustments) which management considers necessary for the fair presentation of the Company's operating results, financial position and cash flows as of and for all periods presented.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies (As Restated)
	Reclassifications
	Certain prior year amounts in the consolidated statements of operations, consolidated statement of cash flows and segment information note have been reclassified to conform to the current year presentation. The reclassifications had no effect on net loss, net cash flows or shareholders' equity.
	Use of Estimates
	The preparation of these financial statements requires management to make estimates and assumptions that affect certain reported amounts of assets, liabilities, revenues, expenses, contingent assets and liabilities, and the related disclosures.  Accordingly, actual results could materially differ from those estimates.  Significant estimates include the allowance for doubtful accounts and credit memos, spare parts inventory obsolescence reserve, useful lives for rental equipment and property and equipment, deferred income taxes, personal property tax receivable and accrual, loss contingencies and the fair value of interest rate swaps and other financial instruments.
	Fair Value of Financial Instruments, Including Derivative Instruments
	The valuation of financial instruments requires the Company to make estimates and judgments that affect the fair value of the instruments. The Company, where possible, bases the fair values of its financial instruments, including its derivative instruments, on listed market prices and third party quotes. Where these are not available, the Company bases its estimates on current instruments with similar terms and maturities or on other factors relevant to the financial instruments.
	Segment Reporting (As Restated)
	We have determined, in accordance with applicable accounting guidance regarding operating segments that we have four reportable segments. We derive our revenues from four principal business activities: (1) Essex Crane equipment rentals; (2) Coast Crane equipment rentals; (3) equipment distribution; and (4) parts and service. These segments are based upon how we allocate resources and assess performance. See Note 16 to the consolidated financial statements regarding our segment information.
	Revenue Recognition
	The Company recognizes revenue, including multiple element arrangements, in accordance with the provisions of applicable accounting guidance. We generate revenue from the rental of cranes and related equipment and other services such as crane and equipment transportation and repairs and maintenance of equipment on rent. In many instances, the Company provides some of the above services under the terms of a single customer Equipment Rental Agreement. The Company also generates revenue from the retail sale of equipment and spare parts and repair and maintenance services provided with respect to non-rental equipment.
	Revenue arrangements with multiple elements are divided into separate units of accounting based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. During the year ended December 31, 2013, the Company used estimated selling price for allocation of consideration related to rental revenues. After an analysis of rental agreements absent any additional services offered by the Company, it was determined that the Company did not have vendor-specific evidence related to rental revenues. Prior to the year ended December 31, 2013, the Company was able to establish vendor-specific objective evidence based on an analysis of rental agreements absent any additional services offered by the Company. The Company uses the estimated selling price for allocation of consideration to transportation services based on the costs associated with providing such services in addition to other supply and demand factors within specific sub-markets. The estimated selling prices of the individual deliverables are not materially different than the terms of the Equipment Rental Agreements.
	Revenue from equipment rentals are billed monthly in advance and recognized as earned, on a straight-line basis over the rental period specified in the associated equipment rental agreement. Rental contract terms may span several months or longer. Because the term of the contracts can extend across financial reporting periods, when rentals are billed in advance, we defer recognition of revenue and record unearned rental revenue at the end of reporting periods so that rental revenue is included in the appropriate period. Repair service revenue is recognized when the service is provided. Transportation revenue from rental equipment delivery service is recognized for the drop off of rental equipment on the delivery date and is recognized for pick-up when the equipment is returned to the Essex service center, storage yard or next customer location. New and used rental equipment and part sales are recognized upon acceptance by the customer and when delivery has occurred. Revenue from repair and maintenance services provided with respect to non-rental equipment is recognized when the service is provided.
	There are estimates required in recording certain repair and maintenance revenues and also in recording any allowances for doubtful accounts and credit memos. The estimates have historically been accurate in all material respects and we do not anticipate any material changes to our current estimates in these areas.
	Cash and Cash Equivalents
	The Company considers all demand deposits, money market accounts and investments in certificates of deposit with a maturity of three months or less at the date of purchase to be cash equivalents. The Company maintained cash deposits in foreign accounts totaling approximately $0.1 million and $0.7 million at December 31, 2013 and 2012, respectively.
	Shipping and Handling Costs and Taxes Collectible from Customers
	The Company classifies shipping and handling amounts billed to customers as revenues and the corresponding expenses are included in cost of revenues in the consolidated statements of operations. The Company accounts for taxes due from customers on a net basis and as such, these amounts are excluded from revenues in the consolidated statements of operations.
	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable are recorded at the invoice price net of an estimate of allowance for doubtful accounts and reserves for credit memos, and generally do not bear interest.
	The allowance for doubtful accounts is the Company’s best estimate of the amount of credit losses in accounts receivable and is included in selling, general and administrative expenses in the consolidated statements of operations. The Company periodically reviews the allowance for doubtful accounts and balances are written off against the allowance when management believes it is probable that the receivable will not be recovered. The Company’s allowance for doubtful accounts and credit memos was approximately $2.5 million and $2.8 million as of December 31, 2013 and 2012, respectively. Bad debt expense was approximately $0.5 million, $1.0 million and $1.0 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	The following table provides a rollforward of the allowance for doubtful accounts for the years ended December 31, 2013 and 2012:
		Year Ended December 31,
		2013			2012
	Beginning balance	$	2,774,720		$	2,915,895
	Provision for allowance for doubtful accounts	519,539			959,543
	Provision for credit memo reserve	1,459,326			1,425,103
	Write-offs and recoveries	(2,268,581		)	(2,525,821		)
	Ending balance	$	2,485,004		$	2,774,720
	Concentrations of Credit Risk
	Financial instruments that potentially subject the Company to a significant concentration of credit risk consist primarily of cash and cash equivalents. The Company may maintain deposits in federally insured financial institutions in excess of federally insured limits. However, management believes the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.
	Another financial instrument account that potentially subjects the Company to a significant concentration of credit risk primarily relates to accounts receivable.  Concentrations of credit risk with respect to accounts receivable is limited because a large number of geographically diverse customers make up the Company’s customer base.
	No single customer represented more than 10% of total revenue or outstanding receivables for any of the periods presented.
	The Company controls credit risk related to accounts receivable through credit approvals, credit limits and other monitoring procedures. The Company also manages credit risk through bonding requirements on its customers and/or liens on projects that the rental equipment is used to complete.
	Inventory
	Inventory is stated at the lower of cost or market.  Spare parts inventory is used to service rental equipment and is sold on a retail basis. Spare parts inventory used to support the crawler crane rental fleet is classified as a non-current asset as it is primarily used to support rental equipment repair operations.  Spare parts inventory used to service rental equipment is recorded as repairs and maintenance expense in the period the parts were issued to a repair project, or, usage is reclassified as additional cost of the rental equipment if the repair project meets certain capitalization criteria as discussed below. Equipment inventory is accounted for using the specific-identification method and retail parts and spare parts inventory are accounted for using the average cost method, which approximates the first-in, first-out method.
	The carrying value of the spare parts inventory is reduced by a reserve representing management’s estimate for obsolete and slow moving items. This obsolescence reserve is an estimate based upon the Company’s analysis by type of inventory, usage and market conditions at the balance sheet dates. The obsolescence reserve was approximately $1.4 million and $1.3 million as of December 31, 2013 and 2012, respectively.
	Rental Equipment
	Rental equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the equipment, which range from 5 to 30 years. In excess of 95% of the assets have a useful life greater than 15 years. Equipment improvement projects with costs in excess of $10,000 for boom trucks, $15,000 for tower and rough terrain cranes and $20,000 for crawler cranes that extend the useful lives or enhance a crane’s capabilities are capitalized in the period they are incurred and depreciated using the straight-line method over an estimated useful life of 7 years. Individual rental equipment items purchased with costs in excess of $5,000 are also capitalized and are depreciated over the useful lives of the respective item purchased. During the years ended December 31, 2013 and 2012, the Company capitalized rental equipment maintenance expenditures of approximately $0.7 million and $0.5 million, respectively.
	Gains and losses on retirements and disposals of rental equipment are included in income from operations. Ordinary repair and maintenance costs are included in cost of revenues in the consolidated statements of operations.
	Property and Equipment
	Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the assets’ estimated useful lives, which are as follows:
	Buildings	30 years
	Building improvements	10 years
	Office equipment	3 to 7 years
	Automobiles, trucks, trailers and yard equipment	4 to 5 years
	Information systems equipment and software	3 years
	Machinery, furniture and fixtures	4 to 7 years
	Expenditures for betterments and renewals in excess of $5,000 that extend the useful lives or enhance the assets’ capabilities are capitalized and are depreciated on the straight-line basis over the remaining lives of the assets.  Gains and losses on retirements and disposals of property and equipment are included in the consolidated statements of operations. The Company capitalized property, plant and equipment expenditures, excluding capitalized software costs, of approximately $1.2 million and $0.5 million during the years ended December 31, 2013 and 2012, respectively.
	External costs incurred by the Company to develop computer software for internal use are capitalized in accordance with applicable accounting guidance. The Company capitalized approximately $29,000 and $0.2 million for the years ended December 31, 2013 and 2012, respectively. Capitalized software development costs include software license fees, consulting fees and certain internal payroll costs and are amortized on a straight-line basis over their useful lives.  During 2011, the Company placed approximately $0.8 million of capitalized costs in service associated with the development of a new Enterprise Resource Planning system (“ERP system”) at Coast Crane.
	Loan Acquisition Costs
	Loan acquisition costs include underwriting, legal and other direct costs incurred in connection with the issuance of the Company’s debt.  These costs are capitalized and amortized using the effective interest method, or using the straight-line method when not materially different that the effective interest method, and are included in interest expense in the consolidated statements of operations.
	Goodwill and Other Intangible Assets
	The Company used the purchase method of accounting for its acquisition of Coast Crane’s assets. The acquisition resulted in an allocation of purchase price to goodwill and other intangible assets. The cost of the Coast Acquisition was first allocated to identifiable assets based on estimated fair values. The excess of the purchase price over the fair value of identifiable assets acquired in the amount of $1.8 million was recorded as goodwill.
	We evaluate goodwill for impairment at the reporting unit level at least annually, or more frequently if triggering events occur or other impairment indicators arise which might impair recoverability. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit. The Company has recorded goodwill of $1.8 million assigned to its Coast Crane equipment rentals, equipment distribution and parts and service reporting units.
	Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units and determination of the fair value of the reporting units. The fair value of the reporting unit is estimated using the income approach, specifically the present value technique using future cash flows, and is compared to the carrying value of the reporting unit. If the fair value of a reporting unit is less than its carrying value, then the implied fair value of goodwill must be estimated and compared to its carrying value to measure the amount of impairment , if any. This analysis requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, estimation of the useful life over which cash flows will occur, and determination of our weighted average cost of capital.
	The estimates used to calculate the fair value of a reporting unit change from year to year based on operating results, market conditions and other factors. Changes in these estimates and assumptions could materially affect the determination of fair value and goodwill impairment for our reporting unit with goodwill.
	The results of our quantitative goodwill impairment tests for the most recent year ended December 31, 2013 indicated that the fair value of our reporting unit with goodwill exceeded its carrying value and no impairment of goodwill was recorded. Similarly, there was no impairment of goodwill recorded for the years ended December 31, 2012 and 2011.
	Identifiable finite lived intangible assets consist of customer relationships and trademarks obtained in the acquisition of Essex Crane Rental Corp.'s and Coast Crane’s assets. The customer relationship intangible and trademark assets are both being amortized on a straight-line basis over their estimated useful lives of 7 years and 5 years, respectively.
	Long-lived Assets
	Long lived assets are recorded at the lower of amortized cost or fair value. As part of an ongoing review of the valuation of long-lived assets and finite-lived intangible assets, the Company assesses the carrying value of these assets if such facts and circumstances suggest that they may be impaired. Losses related to long-lived assets are recorded where indicators of impairment are present and the estimated undiscounted cash flows to be generated by the asset (rental and associated revenues less related operating expenses plus any terminal value) are less than the assets’ carrying value. If the carrying value of the assets will not be recoverable, as determined by the undiscounted cash flows, the carrying value of the assets is reduced to fair value.
	During the year ended December 31, 2013, the Company initiated the process of placing certain crawler crane rental equipment assets into a sealed bid auction, which differs from an absolute auction in that the seller has the right to approve any sales. As a result of the auction proceedings, the possibility that the Company will accept bids below net book value and the assets could be sold before the end of their previously estimated useful life, the Company determined that triggering event had occurred, which caused the Company to determine if an impairment of these long-lived assets was necessary. In addition, certain provisions within the Essex Crane Revolving Credit Facility limit the ability of the Company to sell any individual rental equipment asset, or any group of assets in any six month period, for amounts below a certain percentage of orderly liquidation value. Any sale under these thresholds without a waiver from the lenders would place the Company in default of the Essex Crane Revolving Credit Facility. As of December 31, 2013, the Company did not have a waiver in place and, therefore, did not have the authority to commit to selling the rental equipment assets in the sealed bid auction. As such, the Company concluded the rental equipment assets included in the auction should not be classified as held for sale on December 31, 2013.
	Application of the long-lived asset impairment test requires judgment, including the identification the primary asset, identification of the lowest level of identifiable cash flows that are largely independent of the cash flows of other assets and liabilities and the future cash flows of the long-lived assets. The Company identified its crawler crane rental equipment fleet as the primary asset as it is the basis of all revenue generating activities for Essex Crane, its replacement would require a significant level of investment and its remaining useful life significantly exceeds the remaining useful life of all other assets. The lowest level of identifiable cash flows within the rental equipment fleet is at the equipment model level. Each equipment model group is capable of producing cash flows without other complementary assets and each asset within the specific equipment model groups is interchangeable with any other asset within that equipment model group. The Company tested the recoverability of the rental equipment assets by model using an undiscounted cash flow approach dependent primarily upon estimates of future rental income, orderly liquidation value, estimated selling prices in the sealed bid auction, discount rates and probability factors. Cash flows for each equipment model group utilized a probability weighted forecast that considered the possibility of continuing to rent the assets, selling the assets at varying prices in either the sealed bid auction referred to above or in more orderly transactions at various prices in the future or at the end of their remaining useful lives. The Company estimated that the future cash flows generated by each of the equipment model groups exceeded the carrying value of the assets and no impairment was recorded for the year ended December 31, 2013.
	The Company also assessed whether a triggering event for potential impairment of its other equipment assets existed, and it was determined that no such event occurred for these assets during the year ended December 31, 2013.
Derivative Financial Instruments and Hedging Activities
The Company uses derivative financial instruments for the purpose of hedging the risks associated with interest rate fluctuations on its revolving credit facility with the objective of converting a targeted amount of its floating rate debt to a fixed rate.  The Company has not entered into derivative transactions for speculative purposes, and therefore holds no derivative instruments for trading purposes.
The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking each hedge transaction. All derivative instruments are carried at fair value on the consolidated balance sheets in accordance with applicable accounting guidance.
Cash flow hedges are accounted for by recording the fair value of the derivative instrument on the consolidated balance sheets as either a freestanding asset or liability, with a corresponding offset recorded in accumulated other comprehensive income within the consolidated statements of stockholders’ equity, net of tax. Amounts are reclassified from accumulated other comprehensive income to the consolidated statements of operations in the period or periods the hedged transaction affects earnings.
Derivative gains and losses under cash flow hedges not effective in hedging the change in fair value or expected cash flows of the hedged item are recognized immediately within the consolidated statements of operations. At the hedge’s inception and at least quarterly thereafter, a formal assessment is performed to determine whether changes in the fair values or cash flows of the derivative instruments have been highly effective in offsetting changes in fair values or cash flows of the hedged items and whether they are expected to be highly effective in the future. If it is determined a derivative instrument has not been or will not continue to be highly effective as a hedge, hedge accounting is discontinued. No hedge ineffectiveness was recognized within the consolidated statements of operations during the years ended December 31, 2013, 2012 or 2011.
The Company assumed three interest rate swaps with a combined notional amount of $21.0 million in conjunction with its purchase of Coast Crane’s assets and did not contemporaneously document the hedge designation on the date of assumption in order to qualify for hedge accounting treatment for economic reasons and the forecasted inherent hedge ineffectiveness that would have resulted from the differences in terms of the assumed swaps and the new revolving credit facility. As such, the derivative financial instruments assumed have been recorded at fair value in the accompanying consolidated balance sheets in liabilities with changes in the underlying fair value reported as a component of interest expense in the Company’s consolidated statements of operations.
Income Taxes
The Company uses an asset and liability approach, as required by the applicable accounting guidance, for financial accounting and reporting of income taxes.  Deferred tax assets and liabilities are computed using tax rates expected to apply to taxable income in the years in which those assets and liabilities are expected to be realized. The effect on net deferred tax assets and liabilities resulting from a change in tax rates is recognized as income or expense in the period that the change in tax rates is enacted.
Management makes certain estimates and judgments in determining income tax expense for financial statement purposes.  These estimates and judgments are applied in the calculation of certain tax credits and in the calculation of the deferred income tax expense or benefit associated with certain deferred tax assets and liabilities.  Significant changes to these estimates may result in an increase or decrease to the Company’s tax provision in a subsequent period.
Management assesses the likelihood that it will be able to recover its deferred tax assets.  If recovery is not likely, the Company will increase its provision for income taxes by recording a valuation allowance against the deferred tax assets that are not more likely than not to be realized. The Company follows the applicable guidance related to the accounting for uncertainty in income taxes.
Stock based compensation
Stock based compensation is accounted for in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"), which results in compensation expense being recorded over the requisite service or vesting period based on the fair value of the share based compensation at the date of grant.
Foreign Currency Translation
The functional currency of the Company’s Canadian subsidiary is the Canadian dollar. Assets and liabilities of the foreign subsidiary are translated into U.S. dollars at year-end exchange rates, and revenue and expenses are translated at average rates prevailing during the year. Gains or losses from these translation adjustments are included in accumulated other comprehensive income (loss), a separate component of stockholders’ equity.
Recently Issued and Adopted Accounting Pronouncements
In February 2013, the Financial Accounting Standards Board ("FASB") issued authoritative guidance regarding the reporting of reclassifications out of accumulated other comprehensive income. Under the new guidance, an entity has the option to present either parenthetically on the face of the financial statements or in the notes, significant amounts reclassified from each component of accumulated other comprehensive income and the statement of operations line items affected by the reclassification. The amendment does not change the current requirements for reporting net income or other comprehensive income in the financial statements. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. The Company adopted this guidance during the three months ended March 31, 2013 and has disclosed the reclassifications out of other comprehensive income and the affect on the statement of operations line items within the notes to the consolidated financial statements.
In July 2013, the FASB issued authoritative guidance regarding the financial statement presentation of unrecognized tax benefits. Under the new guidance, unrecognized tax benefits, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax benefit is disallowed. In situations where a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be netted with the deferred tax asset. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The company will adopt this guidance for the fiscal year beginning January 1, 2014. Adoption of this guidance is not expected to have a material impact on the Company's financial results.

Accounting Changes and Error Corrections [Text Block]	Restatement
	On March 17, 2015, the Company concluded that certain of the Company's previously issued Consolidated Financial Statements, including those for the period covered by this report, should not be relied upon due to errors relating to the Company's classification of its revolving credit facilities and errors related to segment reporting.  Management concluded that (i) reclassification of certain of the obligations under the revolving credit facilities as short term obligations is appropriate under relevant accounting guidance that provides for such classification when a credit facility includes a subjective acceleration clause and a traditional lock-box arrangement and (ii) the equipment rental operating segment of the Company's two operating subsidiaries, Essex Crane and Coast Crane, should not be aggregated, but reported as separate segments, under applicable accounting guidance that provides for segment reporting when two operating segments do not share similar economic characteristics based on certain quantitative measures.  The restatement of the Consolidated Financial Statements included in this report does not have any impact on the net cash flows, cash balances, revenues, net income or earnings per share of the Company, as previously reported.
	The Company has restated its Consolidated Balance Sheets as of December 31, 2013 and December 31, 2012. In addition, Note 8 and Note 16 to the Consolidated Financial Statements have been restated to reflect the correction of these errors.

	Essex Crane Revolving Credit Facility
	In conjunction with the acquisition of Holdings on October 31, 2008, Essex Crane amended its senior secured revolving line of credit facility (“Essex Crane Revolving Credit Facility”), which permitted it to borrow up to $190.0 million with a $20.0 million aggregate sublimit for letters of credit. Essex Crane may borrow up to an amount equal to the sum of 85% of eligible net receivables and 75% of the net orderly liquidation value of eligible rental equipment. The Essex Crane Revolving Credit Facility is collateralized by a first priority security interest in substantially all of Essex Crane’s assets.
	On March 15, 2013, the Essex Crane Revolving Credit Facility was amended and restated to extend the maturity to October 31, 2016. The amendment reduced the maximum amount Essex Crane is able to borrow to $175.0 million. The amendment also provided for increases in the applicable prime rate margin, Euro-dollar LIBOR margin and unused line commitment fee to 1.75%, 3.75% and 0.375%, respectively. Under the amendment, the springing covenant threshold is eliminated and, instead, Essex Crane is required to have availability in excess of 10% of the outstanding commitment and is subject to a fixed charge coverage ratio of 1.10 to 1.00. Further, under the amendment, the aggregate commitment will be reduced by: (i) on an individual transaction basis, 100% of the net cash proceeds from the sales of certain assets and (ii) on an annual basis commencing in 2014, 60% of free cash flow, other than net cash proceeds from certain asset sales, as defined within the amended and restated revolving credit facility. In addition, the maximum commitment may not exceed $165.0 million, $150.0 million and $130.0 million beginning on March 31, 2014, March 31, 2015 and February 28, 2016, respectively. The amendment also provides for an annual limit on certain capital expenditures of $2.0 million and limits the ability of Essex Crane to make distributions to affiliates. All other terms of the October 31, 2008 amendment remained in effect following such amendment.
	Borrowings under the Essex Crane Revolving Credit Facility, as amended, accrue interest at the borrower’s option of either (a) the bank’s prime rate (3.25% at December 31, 2013) plus an applicable margin or (b) a Euro-dollar rate based on the rate the bank offers deposits of U.S. Dollars in the London interbank market (“LIBOR”) (0.17% at December 31, 2013) plus an applicable margin. Essex Crane is also required to pay a monthly commitment fee with respect to the undrawn commitments under the Essex Crane Revolving Credit Facility. At December 31, 2013, the applicable prime rate margin, Euro-dollar LIBOR margin, and unused line commitment fee were 1.75%, 3.75% and 0.375%, respectively. At December 31, 2012 (prior to the amendment described above), the applicable prime rate margin, Euro-dollar LIBOR margin, and unused line commitment fee were 0.25%, 2.25% and 0.25%, respectively.
	The maximum amount that could be borrowed under the Essex Crane Revolving Credit Facility, net of letters of credit, interest rate swaps and other reserves was approximately $170.1 million and $185.8 million as of December 31, 2013 and 2012, respectively. Essex Crane’s available borrowing under its revolving credit facility was approximately $21.9 million and $34.5 million as of December 31, 2013 and 2012, respectively. As of December 31, 2013, there was $9.3 million of available formulated collateral in excess of the maximum borrowing amount of $170.1 million. Although the Essex Crane Revolving Credit Facility limits Essex Crane’s ability to incur additional indebtedness, Essex Crane is permitted to incur certain additional indebtedness, including secured purchase money indebtedness of up to $1.5 million outstanding at any time, subject to certain conditions set forth in the Essex Crane Revolving Credit Facility.
	As a result of the errors in our Consolidated Balance Sheets discussed in Note 3, Essex Crane was in technical default under the Essex Crane Revolving Credit Facility. Such default was waived as of March 19, 2015 by the lenders under such facility. Any failure to be in compliance with any material provision or covenant of these agreements could have a material adverse effect on the Company's liquidity and operations.
	The Essex Crane Revolving Credit Facility includes a subjective acceleration clause and requires the Company to maintain a traditional lock-box. As a result, the Essex Crane Revolving Credit Facility is classified as a short-term obligation within the Company's Consolidated Balance Sheets.
	Coast Crane Revolving Credit Facility
	On November 24, 2010, Coast Crane entered into a new revolving credit facility in conjunction with the acquisition of Coast Crane's assets (the “Coast Crane Revolving Credit Facility”).  The Coast Crane Revolving Credit Facility provided for a revolving loan and letter of credit facility in the maximum aggregate principal amount of $75.0 million with a $2.0 million aggregate principal sublimit for letters of credit.   Coast Crane’s ability to borrow under the Coast Crane Revolving Credit Facility is subject to, among other things, a borrowing base calculated based on  the sum of (a) 85% of eligible accounts, (b) the lesser of 50% of eligible spare parts inventory and $5.0 million, (c) the lesser of 95% of the lesser of (x) the net orderly liquidation value and (y) the invoice cost, of eligible new equipment inventory and $15.0 million and (d) 85% of the net orderly liquidation value of eligible other equipment, less reserves established by the lenders and the liquidity reserve.
	On November 14, 2011 the Coast Crane Revolving Credit Facility was amended and restated to include Coast Crane Ltd. as a signatory to the credit facility. The amendment provided that equipment owned by Coast Crane located in Canada may be included in the borrowing base calculation, which was previously prohibited. As amended, the Coast Crane Revolving Credit Facility agreement is collateralized by a first priority security interest in substantially all of Coast Crane’s and Coast Crane Ltd.’s assets.
	Proceeds of the first borrowing under the amended Coast Crane Revolving Credit Facility in the amount of $1.5 million were used to pay off the remaining balance on the Coast Crane Ltd.'s revolving credit facility at the time of its termination in November 2011.
	On May 7, 2012, the Coast Crane Revolving Credit Facility was amended to provide certain limitations on net capital expenditures and a $3.7 million “first amendment reserve” (as defined in the Coast Crane Revolving Credit Facility). The amendment also provides for a modified fixed charge coverage ratio of 1.20 to 1.00 as well as an obligation of Essex to contribute, or cause to be contributed, to Coast Crane up to $2.5 million to the extent that EBITDA for Coast Crane for the year ending December 31, 2012 was less than $6.0 million. Coast Crane EBITDA for the year ended December 31, 2012 exceeded the $6.0 million threshold and no contribution from Essex was required. The amendment also reduced the amount of certain additional indebtedness, including secured purchase money indebtedness, that Coast Crane may incur to $7.0 million for the year ending December 31, 2012 and $10.0 million thereafter. All other terms of the November 14, 2011 amendment and restatement remained in effect following such amendment.
	A definitional interpretation resulted in Coast Crane's lenders determining that the springing fixed charge coverage ratio of 1.20 to 1.00 (which under the Coast Crane Revolving Credit Facility was triggered if Coast Crane's borrowing availability fell below $8.0 million) was triggered notwithstanding that Coast Crane and Coast Crane Ltd. had combined excess availability of $9.5 million, $8.4 million and $8.5 million as of January 31, 2012, February 29, 2012 and March 31, 2012, respectively. The modified fixed charge coverage ratio included in the May 7, 2012 amendment replaced the springing trailing twelve month fixed charge coverage ratio. The May 7, 2012 amendment also addressed and waived Coast Crane’s non-compliance (which existed as of March 31, 2012) with certain delivery and reporting requirements contained in the Coast Crane Revolving Credit Facility.
	On March 12, 2013, the Coast Crane Revolving Credit Facility was amended and restated to extend the maturity date to March 12, 2017. The amendment also provided for a $40.0 million term loan and reduced the aggregate maximum principal amount of the revolving loan and letter of credit facility by a corresponding amount to $35.0 million. In addition, the amendment provided for scheduled quarterly term loan payments to reduce the term loan principal outstanding by $0.5 million beginning on June 30, 2013. The amounts borrowed under the term loan which are repaid or prepaid may not be reborrowed. All other terms of the May 7, 2012 amendment and restatement remained in effect following such amendment.
	Interest accrues on Coast Crane's outstanding revolving loans and term loan under the revolving credit facility at either a per annum rate equal to (a) LIBOR plus 3.75%, with a 1.50% LIBOR floor or (b) the Base rate plus 2.75%, at Coast Crane’s election. Coast Crane will be obligated to pay a letter of credit fee on the outstanding letter of credit accommodations based on a per annum rate of 3.75%. Interest on the revolving loans and fees on the letter of credit accommodations is payable monthly in arrears. Coast Crane is also obligated to pay an unused line fee on the amount by which the maximum credit under the Coast Crane Revolving Credit Facility exceeds the aggregate amount of revolving loans and letter of credit accommodations based on a per annum rate of 0.50%. At December 31, 2013, the applicable LIBOR rate, Base rate, and unused line commitment fee were 0.24%, 3.25% and 0.50%, respectively. At December 31, 2012, the applicable LIBOR rate, Base rate, and unused line commitment fee were 0.31%, 3.25% and 0.50%, respectively.
	The maximum amount that could be borrowed under the revolving loans under the Coast Crane Revolving Credit Facility was approximately $34.4 million and $66.2 million as of December 31, 2013 and 2012, respectively. Coast Crane’s available borrowing under the Coast Crane Revolving Credit Facility was approximately $8.2 million and $6.9 million, respectively, after certain lender reserves of $8.9 million and $8.8 million as of December 31, 2013 and 2012, respectively. As of December 31, 2012, there was approximately $0.2 million of available formulated collateral in excess of the maximum borrowing amount of $75.0 million. Although the Coast Crane Revolving Credit Facility limits Coast Crane’s and Coast Crane Ltd.’s ability to incur additional indebtedness, Coast Crane and Coast Crane Ltd. are permitted to incur certain additional indebtedness, including secured purchase money indebtedness, subject to certain conditions set forth in the Coast Crane Revolving Credit Facility.
	As of December 31, 2013, the outstanding balance on the term loan portion of the Coast Crane Revolving Credit Facility was $38.5 million with $2.0 million of the outstanding balance classified as a current liability as a result of the scheduled quarterly term loan payments of $0.5 million that began on June 30, 2013.
	As a result of the errors in our Consolidated Balance Sheets discussed in Note 3, Coast Crane was in technical default under the Coast Crane Revolving Credit Facility. Such default was waived as of March 20, 2015 by the lenders under such facility. Any failure to be in compliance with any material provision or covenant of these agreements could have a material adverse effect on the Company's liquidity and operations.
	The Coast Crane Revolving Credit Facility includes a subjective acceleration clause and requires the Company to maintain a traditional lock-box for Coast Crane and a springing lock-box for Coast Crane Ltd. As a result, the Coast Crane Revolving Credit Facility, with respect to Coast Crane borrowings, is classified as a short-term obligation within the Company's Consolidated Balance Sheets. The Coast Crane Ltd. borrowings under the Coast Crane Revolving Credit facility are classified as long-term obligations within the Company's Consolidated Balance Sheets.
	Unsecured Promissory Notes
	In November 2010, the Company entered into an agreement with the holders of certain Coast Crane indebtedness pursuant to which such holders agreed, in consideration of the assumption of such indebtedness by the Company, to exchange such indebtedness for one or more promissory notes issued by the Company in the aggregate principal amount of $5.2 million. As additional consideration under the agreement, the Company agreed to issue 90,000 warrants to the holders of such indebtedness entitling the holder thereof to purchase up to 90,000 shares of Essex Rental common stock at an exercise price of $0.01 per share, and to reimburse such holders for certain legal fees incurred in connection with the transaction. The warrants were exercised in full on October 24, 2013.
	In accordance with accounting guidance related to debt issued with conversion or other options, the fair value of the detachable warrants of $0.3 million is recorded as a discount to the principal balance outstanding with an offset to additional paid-in capital on the consolidated statements of stockholders’ equity and will be amortized on a straight-line basis over the three years life of the notes as additional interest expense on the consolidated statement of operations, which is not materially different than the effective interest method. The unamortized balance of this discount was zero and $0.1 million as of December 31, 2013 and 2012, respectively.
	During the year ended December 31, 2013, the Company made principal payments totaling $1.6 million to reduce the outstanding balance of the unsecured promissory notes. As of December 31, 2013 and 2012, the outstanding principal balance on the unsecured promissory notes was approximately $3.7 million and $5.1 million, respectively.
	Interest accrues on the outstanding promissory notes at a per annum rate of 10% and is payable annually in arrears.
	The unsecured promissory notes were amended and restated to extend the maturity date to the earlier of October 31, 2016 or the consummation of any Essex Crane Revolving Credit Facility refinancing to the extent that the terms and conditions of the refinancing permit the Company to use the proceeds from refinancing for such purpose. In addition, beginning on January 1, 2014, interest will accrue on the outstanding promissory notes at a per annum rate of 18% and is payable in arrears.
	As a result of the errors in our Consolidated Balance Sheets discussed in Note 3, the Company was in technical default under the unsecured promissory notes. Such default was waived as of March 24, 2015 by the lenders. Any failure to be in compliance with any material provision or covenant of these agreements could have a material adverse effect on the Company's liquidity and operations.
	Purchase Money Security Interest Debt
	As of December 31, 2013, the Company's purchase money security interest debt consisted of the financing of eleven pieces of equipment. Ten of these debt obligations accrue interest at rates that range from LIBOR plus 3.25% to LIBOR plus 5.38% per annum with interest payable in arrears. One of the debt obligations accrues interest at a rate of 8.29%. The obligations are secured by the equipment purchased and have maturity dates that range from September 2015 to October 2018. As these loans are amortizing, approximately $1.0 million of the total $2.9 million in principal payments is due prior to December 31, 2014 and as such, this amount is classified as a current liability in the accompanying consolidated balance sheets as of December 31, 2013.
	As of December 31, 2012, the purchase money security interest debt consisted of the financing of nine pieces of equipment with an outstanding balance of approximately $3.0 million. The interest rates at December 31, 2012 ranged from LIBOR plus 3.25% to LIBOR plus 5.38%.
	As described above, Essex Crane and Coast Crane (including Coast Crane Ltd.) are permitted to incur up to $1.5 million and $10.0 million, respectively, of secured purchase money indebtedness under the terms of, and subject to certain conditions set forth in, the Essex Crane Revolving Credit Facility and Coast Crane Revolving Credit Facility, respectively.
	As a result of the errors in our Consolidated Balance Sheets discussed in Note 3, the Company was in technical default under the purchase money security interest debt agreements. Such default was waived as of March 18, 2015 by the lenders. Any failure to be in compliance with any material provision or covenant of these agreements could have a material adverse effect on the Company's liquidity and operations.
	The following table summarizes the aggregate maturities of the Company’s debt for the next five years and thereafter as of December 31, 2013:

Derivatives and Hedging Activities - Interest Rate Swap Agreement	12 Months Ended
	Dec. 31, 2013
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities - Interest Rate Swap Agreement	Derivatives and Hedging Activities – Interest Rate Swap Agreement
	Risk Management Objective of Using Derivatives
	The Company is exposed to certain risks arising from both its business operations and economic conditions.  The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates.  The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s investments and borrowings.
	Cash Flow Hedges of Interest Rate Risk
	The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy.  During the year ended December 31, 2012, the Company had four interest rate swaps outstanding, which involve receipt of variable-rate amounts from counterparties in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amounts.
	Essex Crane Interest Rate Swap
	In November 2008, the Company entered into an interest rate swap agreement with the lead lender of its Essex Crane revolving credit facility to hedge its exposure to interest rate fluctuations.  The swap agreement had a notional principal amount of $100.0 million and matured in November 2012. Under the agreement, the Company paid a 2.71% fixed interest rate plus the applicable margin under the revolving credit facility (or a total interest rate of 4.96%). This interest rate swap was designated as a cash flow hedge.
	The swap agreement established a fixed rate of interest for the Company and required the Company or the bank to pay a settlement amount depending upon the difference between the 30 day floating LIBOR rate and the swap fixed rate of 2.71%.  The differential to be paid or received under the swap agreement had been accrued and paid as interest rates changed and such amounts were included in interest expense for the respective period.  Interest payment dates for the revolving loan were dependent upon the interest rate options selected by the Company.  Interest rates on the revolving credit facility were determined based on Wells Fargo’s prime rate or LIBOR rate, plus a margin depending on certain criteria in the agreement.
	The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges were recorded in accumulated other comprehensive income and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives was recognized directly in earnings. There was no hedge ineffectiveness recognized during the years ended December 31, 2012 or 2011.
	For the year ended December 31, 2012, the change in net unrealized loss on the derivative designated as a cash flow hedge reported as a component of other accumulated comprehensive income was an increase of $2.1 million ($1.3 million net of tax). For the year ended December 31, 2011, the change in net unrealized loss on the derivative designated as a cash flow hedge reported as a component of other accumulated comprehensive income was an increase of $1.8 million ($1.1 million net of tax). Amounts reported in accumulated other comprehensive income related to derivatives were reclassified to interest expense as interest payments were made on the Company’s variable-rate debt.
	Coast Crane Interest Rate Swaps
	The Company assumed three interest rate swaps in conjunction with the Coast Acquisition. The assumed interest rate swaps each had a notional amount of $7.0 million each and expired on May 18, 2012. Under the agreements, the Company paid fixed interest of 5.62% and received three-month LIBOR. The Company did not contemporaneously document the hedge designation on the date of assumption in order to quality for hedge accounting treatment due to economic reasons and the projected inherent hedge ineffectiveness.  The changes in fair values of the assumed swaps for the year ended December 31, 2012 were an unrealized gain of approximately $0.4 million and are reported within interest expense of other income (expenses) in the consolidated statement of operations. The changes in fair values of the assumed swaps for the year ended December 31, 2011 were an unrealized gain of approximately $1.0 million and are reported within interest expense of other income (expenses) in the consolidated statement of operations.
	Essex Rental Corp. Summary
	The weighted average interest rate of the Company’s total debt outstanding, including the impact of the interest rate swaps was 4.41% and 3.49% at December 31, 2013 and 2012, respectively. The impact of the interest rate swaps resulted in an increase in interest expense of approximately $2.3 million for the year ended December 31, 2012.
	The table below presents the effect of the Company’s derivative financial instruments on the consolidated statements of operations for the years ended December 31, 2013, 2012 and 2011.  These amounts are presented as accumulated other comprehensive income (loss) (“OCI”).

Fair Value Disclosures [Abstract]
Fair Value	Fair Value
	The FASB issued a statement on Fair Value Measurements which, among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis and clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the standard establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:
	•	Level 1 - Observable inputs such as quoted prices in active markets:
	•	Level 2- Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and
	•	Level 3 - Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
	The fair value of the Company’s total debt obligations was approximately $212.0 million and $217.2 million as of December 31, 2013 and 2012, respectively, calculated using a discounted cash flows approach at a market rate of interest. The inputs used in the calculation are classified within Level 2 of the fair value hierarchy.
	The fair values of the Company’s financial instruments, other than debt obligations, including cash and cash equivalents approximate their carrying values. The Company bases its fair values on listed market prices or third party quotes when available. If not available, then the Company bases its estimates on instruments with similar terms and maturities.

	Diluted earnings (loss) per share	$	(0.39	)	$	(0.52	)	$	(0.72	)
	Basic earnings per share ("EPS") is computed by dividing net income by the weighted average number of common shares outstanding during the period. Included in the weighted average number of shares outstanding for the years ended December 31, 2013, 2012 and 2011 are 493,670, 493,670 and 632,911, respectively, weighted average shares of common stock for the effective conversion of the retained interest in Holdings into common stock of the Company. Diluted EPS adjusts basic EPS for the effects of Warrants, Units and Options; only in the periods in which such effect is dilutive.
	As part of the initial public offering in March 2007, the Company issued an Underwriter Purchase Option (“UPO”) to purchase 600,000 Units at an exercise price of $8.80 per unit. Each unit consisted of one share of the Company’s common stock and one warrant. Each warrant entitled the holder to purchase from the Company one share of common stock at an exercise price of $5.00 per share. The UPO expired unexercised on March 4, 2012.
	The weighted average UPO Units that could be converted into 1,200,000 common shares for the year ended December 31, 2011 were not included in the computation of diluted earnings per share because the effects would be anti-dilutive. The weighted average restricted stock outstanding that could be converted into 5,411, 83,469 and 81,687 common shares for the years ended December 31, 2013, 2012 and 2011, respectively, were not included in the computation of diluted earnings per share because the effects would be anti-dilutive. Weighted average options outstanding that could be converted into 55,235, zero and 107,703 common shares for the years ended December 31, 2013, 2012 and 2011, respectively, were not included in the computation of diluted earnings per share because the effects would be anti-dilutive. Weighted average warrants outstanding that could be converted into 72,797, 89,745 and 114,096 common shares for the years ended December 31, 2013, 2012 and 2011, respectively, were outstanding but were not included in the computation of diluted earnings per share because the effects would be anti-dilutive.
	As of December 31, 2013 and 2012, there were 1,213,879 and 1,474,719 stock options, respectively, outstanding which are exercisable at weighted average exercise prices of $4.87 and $5.45, respectively. As of December 31, 2012, there were 90,000 privately-issued warrants outstanding, which were exercisable at a weighted average exercise price of $0.01. The warrants were fully exercised on October 24, 2013.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes
	The Company uses an asset and liability approach, as required by the applicable accounting guidance for financial accounting and reporting of income taxes. Deferred tax assets and liabilities are computed using tax rates expected to apply to taxable income in the years in which those assets and liabilities are expected to be realized. The effect on net deferred tax assets and liabilities resulting from a change in tax rates is recognized as income or expense in the period that the change in tax rates is enacted.
	The Company makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments are applied in the calculation of certain tax credits and in the calculation of the deferred income tax expense or benefit associated with certain deferred tax assets and liabilities. Significant changes to these estimates may result in an increase or decrease to the Company's tax provision in a subsequent period.
	The Company assesses the likelihood that it will be able to recover its deferred tax assets. If recovery is not likely, the Company will increase its provision for income taxes by recording a valuation allowance against the deferred tax assets that are not more likely than not to be realized.
	The Company follows the applicable accounting guidance related to the accounting for uncertainty in income taxes. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits in income tax expense.
	The Company files income tax returns in the United States federal jurisdiction and in most state jurisdictions. The Company is subject to U. S. federal and state income tax examinations for years 2010 through 2013, however net operating loss carry-forwards from years prior to 2010 also remain open to examination as part of any year utilized in the future. Coast Crane Ltd. is subject to Canadian income tax examinations for the years 2007 through 2012.
	The Company makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments are applied in the calculation of certain tax credits and in the calculation of the deferred income tax expense or benefit associated with certain deferred tax assets and liabilities. Significant changes to these estimates may result in an increase or decrease to the Company's tax provision in a subsequent period.
	At December 31, 2013, the Company had unused federal net operating loss carry-forwards totaling approximately $143.8 million that begin expiring in 2021. At December 31, 2013, the Company also had unused state net operating loss carry-forwards totaling approximately $77.3 million that expire between 2014 and 2033. The Company had unused federal net operation loss carry-forwards of approximately $138.9 million and unused state net operation loss carry-forwards of approximately $71.5 million at December 31, 2012.
	Income tax (benefit) expense consists of the following:

	The Company's current income tax expense for the year ended December 31, 2013 relates primarily to Canadian withholding taxes, New York state audit assessments and Canadian Revenue Agency audit assessments. The Company's deferred income tax benefit for the year ended December 31, 2013 relates primarily to an increase in net operating loss carry-forwards, reduced by an increase in deferred tax liability for rental equipment and other property and equipment.
	The Company's current income tax expense for the year ended December 31, 2012 relates primarily to current year state income taxes and prior year income tax true-ups. The Company's deferred income tax benefit for the year ended December 31, 2012 relates primarily to an increase in net operating loss carry-forwards, reduced by an increase in deferred tax liability for rental equipment and property and equipment and a change in the estimated state deferred income tax rate resulting from various state law changes and estimated future apportionment by state.
	The Company’s current income tax benefit for the year ended December 31, 2011 relates to a decrease in unrecognized tax benefits. The Company’s deferred income tax benefit for the year ended December 31, 2011 primarily relates to the reduction in deferred tax liability for rental equipment and property and equipment and an increase in net operating loss.
	The following table provides a reconciliation between the federal statutory tax rate and the Company’s actual effective tax rate:
		For the Years Ended December 31,
		2013			2012			2011
	Federal statutory rate	35	%		35	%		35	%
	State and local taxes	5.5	%		(2.8	)%		3.4	%

	Meals, entertainment and other	0.1	%		0.4	%		(0.6	)%
	Effective income tax rate	34.4	%		30.5	%		38.6	%
	The Company's effective tax rate for the year ended December 31, 2013 was lower than the statutory rate primarily due to the impact of the stock option shortfall, Canadian withholding taxes and foreign tax differential.
	The Company's effective tax rate for the year ended December 31, 2012 was lower than the statutory rate primarily due to a change in the estimated state and local tax rates which are expected to apply in future years when the Company's temporary differences are expected to reverse, and adjustments to previously recognized deferred tax assets. The change in the estimated state and local taxes rates is the result of newly enacted state law changes and estimated future apportionment percentages in various states, which are expected to apply in future years when the Company's temporary differences are expected to reverse.
	The Company's effective tax rate for the year ended December 31, 2011 was higher than the statutory rate primarily due to state and local taxes. The increase in effective tax rate related to a small increase in the state deferred tax rates at Essex Crane, which was partially offset by an additional state net operating loss valuation allowance. The Essex Crane state deferred rate decreased slightly due to a reduction in forecasted apportionment from higher tax rate states to lower tax rate states.
	The tax effects of temporary differences that give rise to deferred tax assets and liabilities are as follows:
		For the Year Ended December 31,
		2013				2012
	Deferred tax assets:
	Federal and state net operating loss carry-forwards	$	55,825,699			$	53,906,741

		For the Years Ended December 31,
		2013				2012
	Amounts included in the consolidated balance sheets:
	Current deferred tax assets	$	2,878,214			$	3,022,625
	Long-term deferred tax liabilities	(40,868,968		)		(46,258,254		)
	Net deferred tax liabilities	$	(37,990,754	)		$	(43,235,629	)
At December 31, 2013, the Company has federal net operating loss carry-forward totaling approximately $143.8 million that begin expiring on December 31, 2021. The Company recognizes a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. The Company determined it is more likely than not that it will realize the federal deferred tax assets due to the reversal of federal deferred tax liabilities. The federal deferred tax liabilities significantly exceed the federal deferred tax assets and based on the reversing pattern the Company has concluded that substantially all of the federal deferred tax liabilities are expected to reverse and be a sufficient source of future federal taxable income within the period of time available for existing net operating loss carry-forwards and other federal deferred tax assets. The federal deferred tax liability is of the same character as the differences giving rise to the federal deferred tax assets. Also, if the Company experiences substantial changes in ownership, the net operating loss carry-forwards would be subject to an annual limitation pursuant to Section 382 which may impact the realization of the net operating loss carry-forwards. The Company does not believe that the realization of the prior year net operating loss carry-forwards are impacted by a Section 382 limitation.
The Company also has state net operating loss carry-forwards totaling approximately $77.3 million. The Company increased its valuation allowance related to state net operating loss carry-forwards by $0.2 million during the year ended December 31, 2013. The state deferred tax liabilities significantly exceed the state deferred tax assets and based on the reversing pattern the Company has concluded that substantially all of the state deferred tax liabilities are expected to reverse within the period of time available to fully utilize all State deferred tax assets except for certain State net operating losses, with shorter expirations. Based on the reversing schedule performed on a state by state basis the Company has concluded that a valuation allowance of $0.8 million is required. These states required a valuation allowance because the net operating loss carry-forward periods range from five to fifteen years and are expected to expire before being utilized, based upon the scheduled reversal of the deferred tax liabilities. The Company has had net operating losses in these states in the past and limited apportionment currently in these states. Finally, the Company is not relying upon tax planning strategies as the Company has not identified any tax planning strategies that are prudent, feasible and available.
The following table presents the estimated future net operating loss expiration schedule by date and jurisdiction for each of the subsequent ten years and thereafter as of December 31:
		Jurisdiction
		Federal			State
31-Dec-14		—			1,595,000
31-Dec-15		—			1,267,000
31-Dec-16		—			3,475,000
31-Dec-17		—			6,052,000
31-Dec-18		—			3,658,000
31-Dec-19		—			4,025,000
31-Dec-20		—			2,111,000
31-Dec-21		2,000			8,116,000
31-Dec-22		11,424,000			8,396,000
31-Dec-23		14,238,000			4,924,000
Thereafter		118,105,000			33,685,000
Total		143,769,000			77,304,000
The Company also has remaining excess tax goodwill of approximately $3.1 million as of December 31, 2013 associated with the acquisition of Holdings. The excess tax goodwill will be amortized and deducted on the tax return over the remaining three year term. However, the excess tax goodwill is unrecorded for book purposes and cannot be used as a benefit to the income tax provision until the amortization deductions are realized through the reduction of taxable income in future years. The Company had remaining excess tax goodwill of approximately $3.1 million at December 31, 2012.
The Company had approximately $0.1 million and $0.1 million of unrecognized tax benefits, net of federal income tax benefit, at December 31, 2013 and 2012, respectively, all of which will impact the Company's effective tax rate if recognized.
A reconciliation of the approximate beginning and ending amounts of gross unrecognized tax benefits is as follows:
	Year Ended December 31,
	2013				2012
Balance at beginning of year	$	100,000			$	100,000
Increase for changes to tax positions in prior years, net	—				—
Balance at end of year	$	100,000			$	100,000
The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits in income tax expense. To the extent interest is not assessed with respect to uncertain tax positions, amounts accrued will be reduced and reflected as a reduction of the overall income tax provision. The Company had no accrual for interest and penalties for the years ended December 31, 2013, 2012, and 2011 as the Company has significant net operating loss carry-forwards which would be reduced if any payment were due under audit.

Stock Based Compensation	Stock Based Compensation
	The Company may issue up to 1,500,000 shares of common stock pursuant to its 2011 Long-term Incentive Plan to employees, non-employee directors and consultants of the Company. Options to purchase shares of common stock are granted at its market price on the grant date and expire ten years from issuance.
	The Company may issue up to 1,575,000 shares of common stock pursuant to its 2008 Long-term Incentive Plan to employees, non-employee directors and consultants of the Company. Options to purchase shares of common stock are granted at its market price on the grant date and expire ten years from issuance.
	Stock Options
	Stock options granted to employees have a 10 year life and vest one-third annually beginning one year from the date of issue. The Company calculates stock option compensation expense based on the grant date fair value of the award and recognizes expense on a straight-line basis over the three year service period of the award. The Company has granted to certain key members of management options to purchase 75,000 shares at $3.02 per share, 100,000 shares at $4.30 per share, 423,750 shares at $5.58 per share, 485,969 shares at $6.45 per share, and 565,000 shares at $4.50 per share on grant dates of November 15, 2013, June 18, 2013, January 14, 2011, March 18, 2010, and December 18, 2008, respectively.
	The fair values of the stock options granted are estimated at the date of grant using the Black-Scholes option pricing model. The model is sensitive to changes in assumptions which can materially affect the fair value estimate. The Company’s method of estimating expected volatility for the December 18, 2008 and March 18, 2010 option grants were based on the volatility of its peers since the Company only had operations for a short period of time as of the grant date. The Company’s method of estimating the expected volatility for the January 14, 2011, June 18, 2013 and November 17, 2013 option grants were based on the volatility of its own common shares outstanding. The expected dividend yield was estimated based on the Company’s expected dividend rate over the term of the options. The expected term of the options was based on management’s estimate, and the risk-free rate is based on U.S. Treasuries with a term approximating the expected life of the options.
	Based on the results of the model, the weighted average fair value of the stock options granted were $1.95, $2.79, $3.19, $3.76 and $2.54 per share for the options granted on November 15, 2013, June 18, 2013, January 14, 2011, March 18, 2010, and December 18, 2008, respectively, using the following assumptions:

	On November 11, 2013 and May 31, 2013, the Company entered into separation agreements with its former Chief Executive Officer and Chief Financial Officer, respectively. In accordance with the terms of the separation agreements, and as permitted under the terms of the applicable option awards, the Company agreed that options awarded to the former executives of the Company on December 18, 2008 and January 14, 2011, to the extent vested, will remain exercisable until the ten year anniversary of the applicable grant date, instead of expiring 90 days following the date employment was terminated, as provided in the option award agreements. As a result of the modification, the Company incurred additional non-cash stock compensation expense of approximately $0.9 million during the year ended December 31, 2013. Additionally, the separation agreements resulted in the forfeiture of 403,353 vested options issued under the March 18, 2010 option grant and 32,487 unvested options issued under the January 14, 2011 option grant.

Segment Information	Segment Information (As Restated)
	The Company has identified four reportable segments: Essex Crane equipment rentals, Coast Crane equipment rentals, equipment distribution, and parts and service. These segments are based upon how management of the Company allocates resources and assesses performance. The Essex Crane and Coast Crane equipment rental segments includes rental, transportation, used rental equipment sales and repairs of rental equipment. There were no sales between segments for any of the periods presented. Selling, general, and administrative expenses as well as all other income and expense items below gross profit are not generally allocated to our reportable segments.
	We do not compile discrete financial information by our segments other than the information presented below. The following table presents information about our reportable segments related to revenues and gross profit:

	The Company operates primarily in the United States. Our sales to international customers for the years ended December 31, 2013, 2012 and 2011 were 9.6%, 12.2% and 5.5% of total revenues, respectively. Sales to customers in Canada represented 8.4%, 10.1% and 4.7% of total revenues for the years ended December 31, 2013, 2012 and 2011, respectively. No one customer accounted for more than 10% of our revenues on an overall or segmented basis except as described below. Within the equipment distribution segment and for the year ended December 31, 2013, one customer individually accounted for approximately 25.3% of revenues on a segmented basis. Four customers individually accounted for approximately 14.2%, 13.8%, 12.6% and 11.6% of revenues on a segmented basis within the equipment distribution segment and for the year ended December 31, 2012. Three customers individually accounted for approximately 14.7%, 12.6% and 10.4% of equipment distribution revenues on a segmented basis for the year ended December 31, 2011. The concentration of revenues from these customers within the equipment distribution segment is directly attributable to the large dollar value of individual transactions and the small number of individual transactions.
	The Company maintains assets in Canada associated with our Coast Crane Ltd. subsidiary. Total assets located in Canada at December 31, 2013 totaled approximately $4.5 million, including long-lived assets totaling approximately $3.5 million.

	Since December 2010, the Company occupies office space at 500 Fifth Avenue, 50th Floor, New York, NY 10110, provided by Hyde Park Real Estate LLC, an affiliate of Laurence S. Levy, our Chairman of the Board of Directors. Such affiliate has agreed that it will make such office space, as well as certain office and administrative services, available to the Company, as may be required by the Company from time to time. Effective January 1, 2012, the Company has agreed to pay such entity $7,688 per month for such services with terms of the arrangement being reconsidered from time to time. Prior to December 2010, the Company maintained an office at 461 Fifth Avenue, 25th Floor, New York, New York pursuant to an agreement with ProChannel Management LLC, also an affiliate of Laurence S. Levy. The Company’s statements of operations for the years ended December 31, 2013, 2012 and 2011 include $0.1 million, $0.1 million and $0.1 million, respectively, of rent expense related to these agreements.
	In November 2010, the Company entered into an agreement with the holders of certain Coast Crane indebtedness pursuant to which such holders agreed, in consideration of the assumption of such indebtedness by the Company, to exchange such indebtedness of $5.2 million for unsecured promissory notes issued by the Company in the aggregate principal amount of $5.2 million plus the receipt of up to 90,000 warrants to purchase Essex common stock at $0.01 per share. The warrants were exercised in full on October 24, 2013. The holders of the unsecured promissory notes were related parties to the Company as they owned a significant amount of the Company’s outstanding shares of common stock at the time of the transaction.
	The Company maintains reserves for personal property taxes.  These reserves are based on a variety of factors including: duration of rental in each county jurisdiction, tax rates, rental contract terms, customer filings, tax-exempt nature of projects or jurisdictions, statutes of limitations and potential related penalties and interest.  Additionally, most customer rental contracts contain a provision that provides that personal property taxes are an obligation to be borne by the lessee.  Where provided in the rental contract, management will invoice the customer for any personal property taxes paid by the Company.  An estimated receivable has been provided in connection with this liability, net of an estimated allowance.  This customer receivable has been presented as other receivables in current assets while the property tax reserve has been included in accrued taxes.
	Management estimated the gross personal property taxes liability and related contractual customer receivable of the Company to be approximately $3.3 million and $2.0 million, respectively, at December 31, 2013. Management estimated the gross personal property taxes liability and related contractual customer receivable of the Company to be approximately $3.0 million and $2.0 million, respectively, at December 31, 2012.
	The Company is subject to a number of claims and proceedings that generally arise in the normal conduct of business.  The Company believes that any liabilities ultimately resulting from these claims will not, individually or in the aggregate, have a material adverse effect on our financial position, results of operations or cash flows.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events
	On February 21, 2014, Coast Crane and Coast Crane Ltd. entered into a First Amendment to the Second Amended and Restated Credit Agreement. The purpose of the First Amendment is to amend the mandatory prepayment provision to exclude proceeds received from permitted equipment asset sales and to waive an event of default that occurred as a result of permitted equipment asset sales and the failure to apply proceeds to the term loan under the Coast Crane Credit Agreement. In addition, the First Amendment amends the borrowing base calculation as it relates to new equipment inventory, and creates a progressive new equipment inventory cap based on a leverage ratio.
	The Coast Crane Credit Agreement provides for a revolving loan and letter of credit facility (the “Coast Crane Facility”), in the maximum aggregate principal amount of $35,000,000 with a $2,000,000 aggregate principal sublimit for letters of credit and a subfacility for revolving loans to Coast Crane Ltd. of up to $10,000,000. The Coast Crane Credit Agreement also provides for a term loan (the “Term Loan”), in the maximum principal amount of $40,000,000 with mandatory principal repayments of $500,000 per quarter beginning on June 30, 2013. Coast Crane and Coast Crane Ltd. may borrow, repay and reborrow under the Coast Crane Facility. Coast Crane’s ability to borrow under the Coast Crane Facility is subject to, among other things, a borrowing base which is calculated as the sum of (a) 85% of eligible Coast Crane accounts, (b) the lesser of 50% of eligible Coast Crane inventory and $5 million, (c) the lesser of (i) 95% of the lesser of (x) the Net Orderly Liquidation Value and (y) the invoice cost, of U.S. Eligible New Sale Equipment Inventory and (ii) the U.S. Eligible New Sale Equipment Inventory Cap (as hereinafter defined) and (d) 85% of the net orderly liquidation value of eligible other equipment, less reserves established by the lenders and the liquidity reserve. Coast Crane Ltd.’s ability to borrow under the Coast Crane Facility is subject to among other things, a borrowing base which is calculated as the sum of (a) 85% of eligible Coast Crane Ltd. accounts, (b) the lesser of 50% of eligible Coast Crane Ltd. inventory and $750,000, (c) the lesser of (i) 95% of the lesser of (x) the net orderly liquidation value and (y) the invoice cost, of eligible new Coast Crane Ltd. equipment and (ii) $2,000,000 and (d) 85% of the net orderly liquidation value of eligible other Coast Crane Ltd. equipment, less reserves established by the lenders and the liquidity reserve.
	The U.S. Eligible New Sale Equipment Inventory Cap shall mean the U.S. Eligible New Sale Equipment Inventory Cap in effect from time to time determined based upon the applicable leverage ratio then in effect. The U.S. Eligible New Sale Equipment Inventory Cap is adjusted from $4 million to $15 million based on the applicable leverage ratio then in effect and also based on the amount of U.S. Eligible New Sale Equipment Inventory that is under a written agreement to be sold to a customer.

Accounting Policies [Abstract]
Reclassifications	Reclassifications
	Certain prior year amounts in the consolidated statements of operations, consolidated statement of cash flows and segment information note have been reclassified to conform to the current year presentation. The reclassifications had no effect on net loss, net cash flows or shareholders' equity.
Use of Estimates, Policy	Use of Estimates
	The preparation of these financial statements requires management to make estimates and assumptions that affect certain reported amounts of assets, liabilities, revenues, expenses, contingent assets and liabilities, and the related disclosures.  Accordingly, actual results could materially differ from those estimates.  Significant estimates include the allowance for doubtful accounts and credit memos, spare parts inventory obsolescence reserve, useful lives for rental equipment and property and equipment, deferred income taxes, personal property tax receivable and accrual, loss contingencies and the fair value of interest rate swaps and other financial instruments.
Fair Value of Financial Instruments	Fair Value of Financial Instruments, Including Derivative Instruments
	The valuation of financial instruments requires the Company to make estimates and judgments that affect the fair value of the instruments. The Company, where possible, bases the fair values of its financial instruments, including its derivative instruments, on listed market prices and third party quotes. Where these are not available, the Company bases its estimates on current instruments with similar terms and maturities or on other factors relevant to the financial instruments.
Segment Reporting	Segment Reporting (As Restated)
	We have determined, in accordance with applicable accounting guidance regarding operating segments that we have four reportable segments. We derive our revenues from four principal business activities: (1) Essex Crane equipment rentals; (2) Coast Crane equipment rentals; (3) equipment distribution; and (4) parts and service. These segments are based upon how we allocate resources and assess performance. See Note 16 to the consolidated financial statements regarding our segment information.
Revenue Recognition	Revenue Recognition
	The Company recognizes revenue, including multiple element arrangements, in accordance with the provisions of applicable accounting guidance. We generate revenue from the rental of cranes and related equipment and other services such as crane and equipment transportation and repairs and maintenance of equipment on rent. In many instances, the Company provides some of the above services under the terms of a single customer Equipment Rental Agreement. The Company also generates revenue from the retail sale of equipment and spare parts and repair and maintenance services provided with respect to non-rental equipment.
	Revenue arrangements with multiple elements are divided into separate units of accounting based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. During the year ended December 31, 2013, the Company used estimated selling price for allocation of consideration related to rental revenues. After an analysis of rental agreements absent any additional services offered by the Company, it was determined that the Company did not have vendor-specific evidence related to rental revenues. Prior to the year ended December 31, 2013, the Company was able to establish vendor-specific objective evidence based on an analysis of rental agreements absent any additional services offered by the Company. The Company uses the estimated selling price for allocation of consideration to transportation services based on the costs associated with providing such services in addition to other supply and demand factors within specific sub-markets. The estimated selling prices of the individual deliverables are not materially different than the terms of the Equipment Rental Agreements.
	Revenue from equipment rentals are billed monthly in advance and recognized as earned, on a straight-line basis over the rental period specified in the associated equipment rental agreement. Rental contract terms may span several months or longer. Because the term of the contracts can extend across financial reporting periods, when rentals are billed in advance, we defer recognition of revenue and record unearned rental revenue at the end of reporting periods so that rental revenue is included in the appropriate period. Repair service revenue is recognized when the service is provided. Transportation revenue from rental equipment delivery service is recognized for the drop off of rental equipment on the delivery date and is recognized for pick-up when the equipment is returned to the Essex service center, storage yard or next customer location. New and used rental equipment and part sales are recognized upon acceptance by the customer and when delivery has occurred. Revenue from repair and maintenance services provided with respect to non-rental equipment is recognized when the service is provided.
	There are estimates required in recording certain repair and maintenance revenues and also in recording any allowances for doubtful accounts and credit memos. The estimates have historically been accurate in all material respects and we do not anticipate any material changes to our current estimates in these areas.
Cash and Cash Equivalents	Cash and Cash Equivalents
	The Company considers all demand deposits, money market accounts and investments in certificates of deposit with a maturity of three months or less at the date of purchase to be cash equivalents. The Company maintained cash deposits in foreign accounts totaling approximately $0.1 million and $0.7 million at December 31, 2013 and 2012, respectively.
Shipping and Handling Cost	Shipping and Handling Costs and Taxes Collectible from Customers
	The Company classifies shipping and handling amounts billed to customers as revenues and the corresponding expenses are included in cost of revenues in the consolidated statements of operations. The Company accounts for taxes due from customers on a net basis and as such, these amounts are excluded from revenues in the consolidated statements of operations.
Trade and Other Accounts Receivable	Accounts Receivable and Allowance for Doubtful Accounts
	Accounts receivable are recorded at the invoice price net of an estimate of allowance for doubtful accounts and reserves for credit memos, and generally do not bear interest.
	The allowance for doubtful accounts is the Company’s best estimate of the amount of credit losses in accounts receivable and is included in selling, general and administrative expenses in the consolidated statements of operations. The Company periodically reviews the allowance for doubtful accounts and balances are written off against the allowance when management believes it is probable that the receivable will not be recovered. The Company’s allowance for doubtful accounts and credit memos was approximately $2.5 million and $2.8 million as of December 31, 2013 and 2012, respectively. Bad debt expense was approximately $0.5 million, $1.0 million and $1.0 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	The following table provides a rollforward of the allowance for doubtful accounts for the years ended December 31, 2013 and 2012:
		Year Ended December 31,
		2013			2012
	Beginning balance	$	2,774,720		$	2,915,895
	Provision for allowance for doubtful accounts	519,539			959,543
	Provision for credit memo reserve	1,459,326			1,425,103
	Write-offs and recoveries	(2,268,581		)	(2,525,821		)
	Ending balance	$	2,485,004		$	2,774,720
Concentration Risk, Credit Risk	Concentrations of Credit Risk
	Financial instruments that potentially subject the Company to a significant concentration of credit risk consist primarily of cash and cash equivalents. The Company may maintain deposits in federally insured financial institutions in excess of federally insured limits. However, management believes the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held.
	Another financial instrument account that potentially subjects the Company to a significant concentration of credit risk primarily relates to accounts receivable.  Concentrations of credit risk with respect to accounts receivable is limited because a large number of geographically diverse customers make up the Company’s customer base.
	No single customer represented more than 10% of total revenue or outstanding receivables for any of the periods presented.
	The Company controls credit risk related to accounts receivable through credit approvals, credit limits and other monitoring procedures. The Company also manages credit risk through bonding requirements on its customers and/or liens on projects that the rental equipment is used to complete.
Inventory	Inventory
	Inventory is stated at the lower of cost or market.  Spare parts inventory is used to service rental equipment and is sold on a retail basis. Spare parts inventory used to support the crawler crane rental fleet is classified as a non-current asset as it is primarily used to support rental equipment repair operations.  Spare parts inventory used to service rental equipment is recorded as repairs and maintenance expense in the period the parts were issued to a repair project, or, usage is reclassified as additional cost of the rental equipment if the repair project meets certain capitalization criteria as discussed below. Equipment inventory is accounted for using the specific-identification method and retail parts and spare parts inventory are accounted for using the average cost method, which approximates the first-in, first-out method.
	The carrying value of the spare parts inventory is reduced by a reserve representing management’s estimate for obsolete and slow moving items. This obsolescence reserve is an estimate based upon the Company’s analysis by type of inventory, usage and market conditions at the balance sheet dates.
Property, Plant and Equipment	Rental Equipment
	Rental equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the equipment, which range from 5 to 30 years. In excess of 95% of the assets have a useful life greater than 15 years. Equipment improvement projects with costs in excess of $10,000 for boom trucks, $15,000 for tower and rough terrain cranes and $20,000 for crawler cranes that extend the useful lives or enhance a crane’s capabilities are capitalized in the period they are incurred and depreciated using the straight-line method over an estimated useful life of 7 years. Individual rental equipment items purchased with costs in excess of $5,000 are also capitalized and are depreciated over the useful lives of the respective item purchased. During the years ended December 31, 2013 and 2012, the Company capitalized rental equipment maintenance expenditures of approximately $0.7 million and $0.5 million, respectively.
	Gains and losses on retirements and disposals of rental equipment are included in income from operations. Ordinary repair and maintenance costs are included in cost of revenues in the consolidated statements of operations.
	Property and Equipment
	Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the assets’ estimated useful lives, which are as follows:
	Buildings	30 years
	Building improvements	10 years
	Office equipment	3 to 7 years
	Automobiles, trucks, trailers and yard equipment	4 to 5 years
	Information systems equipment and software	3 years
	Machinery, furniture and fixtures	4 to 7 years
	Expenditures for betterments and renewals in excess of $5,000 that extend the useful lives or enhance the assets’ capabilities are capitalized and are depreciated on the straight-line basis over the remaining lives of the assets.  Gains and losses on retirements and disposals of property and equipment are included in the consolidated statements of operations. The Company capitalized property, plant and equipment expenditures, excluding capitalized software costs, of approximately $1.2 million and $0.5 million during the years ended December 31, 2013 and 2012, respectively.
	External costs incurred by the Company to develop computer software for internal use are capitalized in accordance with applicable accounting guidance. The Company capitalized approximately $29,000 and $0.2 million for the years ended December 31, 2013 and 2012, respectively. Capitalized software development costs include software license fees, consulting fees and certain internal payroll costs and are amortized on a straight-line basis over their useful lives.  During 2011, the Company placed approximately $0.8 million of capitalized costs in service associated with the development of a new Enterprise Resource Planning system (“ERP system”) at Coast Crane.
Debt	Loan Acquisition Costs
	Loan acquisition costs include underwriting, legal and other direct costs incurred in connection with the issuance of the Company’s debt.  These costs are capitalized and amortized using the effective interest method, or using the straight-line method when not materially different that the effective interest method, and are included in interest expense in the consolidated statements of operations.
Goodwill and Intangible Assets	Goodwill and Other Intangible Assets
	The Company used the purchase method of accounting for its acquisition of Coast Crane’s assets. The acquisition resulted in an allocation of purchase price to goodwill and other intangible assets. The cost of the Coast Acquisition was first allocated to identifiable assets based on estimated fair values. The excess of the purchase price over the fair value of identifiable assets acquired in the amount of $1.8 million was recorded as goodwill.
	We evaluate goodwill for impairment at the reporting unit level at least annually, or more frequently if triggering events occur or other impairment indicators arise which might impair recoverability. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit. The Company has recorded goodwill of $1.8 million assigned to its Coast Crane equipment rentals, equipment distribution and parts and service reporting units.
	Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units and determination of the fair value of the reporting units. The fair value of the reporting unit is estimated using the income approach, specifically the present value technique using future cash flows, and is compared to the carrying value of the reporting unit. If the fair value of a reporting unit is less than its carrying value, then the implied fair value of goodwill must be estimated and compared to its carrying value to measure the amount of impairment , if any. This analysis requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, estimation of the useful life over which cash flows will occur, and determination of our weighted average cost of capital.
	The estimates used to calculate the fair value of a reporting unit change from year to year based on operating results, market conditions and other factors. Changes in these estimates and assumptions could materially affect the determination of fair value and goodwill impairment for our reporting unit with goodwill.
	The results of our quantitative goodwill impairment tests for the most recent year ended December 31, 2013 indicated that the fair value of our reporting unit with goodwill exceeded its carrying value and no impairment of goodwill was recorded. Similarly, there was no impairment of goodwill recorded for the years ended December 31, 2012 and 2011.
	Identifiable finite lived intangible assets consist of customer relationships and trademarks obtained in the acquisition of Essex Crane Rental Corp.'s and Coast Crane’s assets. The customer relationship intangible and trademark assets are both being amortized on a straight-line basis over their estimated useful lives of 7 years and 5 years, respectively.
Impairment or Disposal of Long-Lived Assets	Long-lived Assets
	Long lived assets are recorded at the lower of amortized cost or fair value. As part of an ongoing review of the valuation of long-lived assets and finite-lived intangible assets, the Company assesses the carrying value of these assets if such facts and circumstances suggest that they may be impaired. Losses related to long-lived assets are recorded where indicators of impairment are present and the estimated undiscounted cash flows to be generated by the asset (rental and associated revenues less related operating expenses plus any terminal value) are less than the assets’ carrying value. If the carrying value of the assets will not be recoverable, as determined by the undiscounted cash flows, the carrying value of the assets is reduced to fair value.
	During the year ended December 31, 2013, the Company initiated the process of placing certain crawler crane rental equipment assets into a sealed bid auction, which differs from an absolute auction in that the seller has the right to approve any sales. As a result of the auction proceedings, the possibility that the Company will accept bids below net book value and the assets could be sold before the end of their previously estimated useful life, the Company determined that triggering event had occurred, which caused the Company to determine if an impairment of these long-lived assets was necessary. In addition, certain provisions within the Essex Crane Revolving Credit Facility limit the ability of the Company to sell any individual rental equipment asset, or any group of assets in any six month period, for amounts below a certain percentage of orderly liquidation value. Any sale under these thresholds without a waiver from the lenders would place the Company in default of the Essex Crane Revolving Credit Facility. As of December 31, 2013, the Company did not have a waiver in place and, therefore, did not have the authority to commit to selling the rental equipment assets in the sealed bid auction. As such, the Company concluded the rental equipment assets included in the auction should not be classified as held for sale on December 31, 2013.
	Application of the long-lived asset impairment test requires judgment, including the identification the primary asset, identification of the lowest level of identifiable cash flows that are largely independent of the cash flows of other assets and liabilities and the future cash flows of the long-lived assets. The Company identified its crawler crane rental equipment fleet as the primary asset as it is the basis of all revenue generating activities for Essex Crane, its replacement would require a significant level of investment and its remaining useful life significantly exceeds the remaining useful life of all other assets. The lowest level of identifiable cash flows within the rental equipment fleet is at the equipment model level. Each equipment model group is capable of producing cash flows without other complementary assets and each asset within the specific equipment model groups is interchangeable with any other asset within that equipment model group. The Company tested the recoverability of the rental equipment assets by model using an undiscounted cash flow approach dependent primarily upon estimates of future rental income, orderly liquidation value, estimated selling prices in the sealed bid auction, discount rates and probability factors. Cash flows for each equipment model group utilized a probability weighted forecast that considered the possibility of continuing to rent the assets, selling the assets at varying prices in either the sealed bid auction referred to above or in more orderly transactions at various prices in the future or at the end of their remaining useful lives. The Company estimated that the future cash flows generated by each of the equipment model groups exceeded the carrying value of the assets and no impairment was recorded for the year ended December 31, 2013.
Derivatives, Methods of Accounting, Hedging Derivatives	Derivative Financial Instruments and Hedging Activities
	The Company uses derivative financial instruments for the purpose of hedging the risks associated with interest rate fluctuations on its revolving credit facility with the objective of converting a targeted amount of its floating rate debt to a fixed rate.  The Company has not entered into derivative transactions for speculative purposes, and therefore holds no derivative instruments for trading purposes.
	The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking each hedge transaction. All derivative instruments are carried at fair value on the consolidated balance sheets in accordance with applicable accounting guidance.
	Cash flow hedges are accounted for by recording the fair value of the derivative instrument on the consolidated balance sheets as either a freestanding asset or liability, with a corresponding offset recorded in accumulated other comprehensive income within the consolidated statements of stockholders’ equity, net of tax. Amounts are reclassified from accumulated other comprehensive income to the consolidated statements of operations in the period or periods the hedged transaction affects earnings.
	Derivative gains and losses under cash flow hedges not effective in hedging the change in fair value or expected cash flows of the hedged item are recognized immediately within the consolidated statements of operations. At the hedge’s inception and at least quarterly thereafter, a formal assessment is performed to determine whether changes in the fair values or cash flows of the derivative instruments have been highly effective in offsetting changes in fair values or cash flows of the hedged items and whether they are expected to be highly effective in the future. If it is determined a derivative instrument has not been or will not continue to be highly effective as a hedge, hedge accounting is discontinued.
Income Tax	Income Taxes
	The Company uses an asset and liability approach, as required by the applicable accounting guidance, for financial accounting and reporting of income taxes.  Deferred tax assets and liabilities are computed using tax rates expected to apply to taxable income in the years in which those assets and liabilities are expected to be realized. The effect on net deferred tax assets and liabilities resulting from a change in tax rates is recognized as income or expense in the period that the change in tax rates is enacted.
	Management makes certain estimates and judgments in determining income tax expense for financial statement purposes.  These estimates and judgments are applied in the calculation of certain tax credits and in the calculation of the deferred income tax expense or benefit associated with certain deferred tax assets and liabilities.  Significant changes to these estimates may result in an increase or decrease to the Company’s tax provision in a subsequent period.
	Management assesses the likelihood that it will be able to recover its deferred tax assets.  If recovery is not likely, the Company will increase its provision for income taxes by recording a valuation allowance against the deferred tax assets that are not more likely than not to be realized. The Company follows the applicable guidance related to the accounting for uncertainty in income taxes.
Share-based Compensation, Option and Incentive Plans	Stock based compensation
	Stock based compensation is accounted for in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"), which results in compensation expense being recorded over the requisite service or vesting period based on the fair value of the share based compensation at the date of grant.
Foreign Currency Transactions and Translations	Foreign Currency Translation
	The functional currency of the Company’s Canadian subsidiary is the Canadian dollar. Assets and liabilities of the foreign subsidiary are translated into U.S. dollars at year-end exchange rates, and revenue and expenses are translated at average rates prevailing during the year. Gains or losses from these translation adjustments are included in accumulated other comprehensive income (loss), a separate component of stockholders’ equity.
New Accounting Pronouncements	Recently Issued and Adopted Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board ("FASB") issued authoritative guidance regarding the reporting of reclassifications out of accumulated other comprehensive income. Under the new guidance, an entity has the option to present either parenthetically on the face of the financial statements or in the notes, significant amounts reclassified from each component of accumulated other comprehensive income and the statement of operations line items affected by the reclassification. The amendment does not change the current requirements for reporting net income or other comprehensive income in the financial statements. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. The Company adopted this guidance during the three months ended March 31, 2013 and has disclosed the reclassifications out of other comprehensive income and the affect on the statement of operations line items within the notes to the consolidated financial statements.
	In July 2013, the FASB issued authoritative guidance regarding the financial statement presentation of unrecognized tax benefits. Under the new guidance, unrecognized tax benefits, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax benefit is disallowed. In situations where a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be netted with the deferred tax asset. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The company will adopt this guidance for the fiscal year beginning January 1, 2014. Adoption of this guidance is not expected to have a material impact on the Company's financial results.
