Accounting Changes and Error Corrections [Abstract]
Restatement	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 September 30, 2013 and December 31, 2012. In addition, Note 5 and Note 13 to the Consolidated Financial Statements have been restated to reflect the correction of these errors.
	The effects of the restatement of certain revolving credit facilities to short-term obligations on the Consolidated Balance Sheet as of September 30, 2013 are as follows:

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies (As Restated)
	Please refer to Note 2 of the Notes to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2012 for a complete description of our significant accounting policies.
	Reclassifications
	Certain prior year amounts in the consolidated cash flow statements 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 13 to the consolidated financial statements regarding our segment information.
	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.

	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 September 30, 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”) (0.18% at September 30, 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 September 30, 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 $170.5 million and $185.8 million as of September 30, 2013 and December 31, 2012, respectively. Essex Crane’s available borrowing under its revolving credit facility was approximately $22.1 million and $34.5 million as of September 30, 2013 and December 31, 2012, respectively. As of September 30, 2013, there was $10.1 million of available formulated collateral in excess of the maximum borrowing amount of $170.5 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 as of September 30, 2013 and for the three and nine months then ended, 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 provides for a $40.0 million term loan and reduces 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 provides 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 September 30, 2013, the applicable LIBOR rate, Base rate, and unused line commitment fee were 0.25%, 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 $35.0 million and $66.2 million as of September 30, 2013 and December 31, 2012, respectively. Coast Crane’s available borrowing under the Coast Crane Revolving Credit Facility was approximately $8.3 million and $6.9 million, respectively, after certain lender reserves of $8.2 million and $8.8 million as of September 30, 2013 and December 31, 2012, respectively. As of September 30, 2013 and December 31, 2012, there was approximately $0.8 million and $0.2 million, respectively, 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 September 30, 2013, the outstanding balance on the term loan portion of the Coast Crane Revolving Credit Facility was $39.0 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 as of September 30, 2013 and for the three and nine months then ended, 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. These 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 $296,400 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 $24,032 and $96,130 as of September 30, 2013 and December 31, 2012, respectively.
	Interest accrues on the outstanding promissory notes at a per annum rate of 10% and is payable annually in arrears.
	As a result of the errors in our Consolidated Balance Sheets discussed in Note 3 as of September 30, 2013 and for the three and nine months then ended, the Company was in technical default under the unsecured promissory notes. Such default was waived as of March 24, 2015 by the lenders under. 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 September 30, 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 $3.2 million in principal payments is due prior to September 30, 2014 and as such, this amount is classified as a current liability in the accompanying consolidated balance sheets as of September 30, 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 as of September 30, 2013 and for the three and nine months then ended, 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.

Derivatives and Hedging Activities - Interest Rate Swap Agreements	9 Months Ended
	Sep. 30, 2013
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities - Interest Rate Swap Agreements	Derivatives and Hedging Activities – Interest Rate Swap Agreements
	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 three and nine months ended September 30, 2012, the Company had one and four interest rate swaps outstanding, respectively, which involved the 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, Essex Crane entered into an interest rate swap agreement with the lead lender of the 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 requires 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 has 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 is recorded in accumulated other comprehensive income and is 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 is recognized directly in earnings. There was no hedge ineffectiveness recognized during the three and nine months ended September 30, 2012.
	For the three and nine months ended September 30, 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 a decrease of $0.6 million ($0.4 million net of tax) and a decrease of $1.7 million ($1.0 million net of tax), respectively. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are 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 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 an interest rate based on three-month LIBOR. The Company did not contemporaneously document the hedge designation on the date of assumption in order to qualify 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 three and nine months ended September 30, 2012 was an unrealized gain of approximately $0 and $0.4 million and was reported as a component of interest expense in the consolidated statement of operations.
	Essex Rental Corp. Summary
	The Company’s consolidated weighted average interest rate of total debt outstanding, including the impact of the interest rate swaps was 4.52% and 3.49% at September 30, 2013 and December 31, 2012, respectively. The impact of the interest rate swaps resulted in an increase in interest expense of approximately $0.6 million for the three months ended September 30, 2012. The impact of the interest rate swaps resulted in an increase in interest expense of approximately $1.9 million for the nine months ended September 30, 2012.

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 $216.8 million and $217.2 million as of September 30, 2013 and December 31, 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, 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	$	(0.08	)	$	(0.08	)	$	(0.24	)	$	(0.39	)
	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 three and nine months ended September 30, 2013 are 493,670 weighted average shares of common stock for the effective conversion of the retained interest in Holdings into common stock of the Company. Included in weighted average number of shares outstanding for the three and nine months ended September 30, 2012 are 632,911 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 zero common shares for the three and nine months ended September 30, 2012 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 3,931 and 82,685 common shares for the three months ended September 30, 2013 and 2012, respectively, and 1,738 and 83,469 common shares for the nine months ended September 30, 2013 and 2012, 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 74,259 and 41,987 common shares for the three months ended September 30, 2013 and 2012, respectively, and 82,433 and 8,514 common shares for the nine months ended September 30, 2013 and 2012, 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 89,779 and 89,764 common shares for the three months ended September 30, 2013 and 2012, respectively, and 89,783 and 89,749 common shares for the nine months ended September 30, 2013 and 2012, respectively, were outstanding but were not included in the computation of diluted earnings per share because the effects would be anti-dilutive.
	As of September 30, 2013 and 2012, there were 90,000 privately-issued warrants outstanding, which were exercisable at a weighted average exercise price of $0.01. These warrants were fully exercised on October 24, 2013. As of September 30, 2013 and 2012, there were 1,430,459 and 1,474,719 stock options, respectively, outstanding which are exercisable at weighted average exercise prices of $5.29 and $5.45, respectively.

Income Taxes	Income Taxes
	The Company’s effective tax rate of 37.6% for the nine months ended September 30, 2013 was higher than the statutory federal rate due to state taxes. The Company’s effective tax rate of 33.8% for the nine months ended September 30, 2012 was lower than the statutory federal rate due to state taxes.
	As of September 30, 2013, the Company has unused federal net operating loss carry-forwards totaling approximately $145.5 million that begin expiring in 2022. As of September 30, 2013, the Company also has unused state net operating loss carry-forwards totaling approximately $77.7 million which expire between 2013 and 2032. The net operating loss carry-forwards are primarily from the acquisition of Holdings and losses in recent years. The Company had unused federal and state net operating loss carry-forwards totaling approximately $138.9 million and $71.5 million, respectively, as of December 31, 2012.
	The Company also has remaining excess tax goodwill of approximately $3.1 million as of September 30, 2013 associated with the acquisition of Holdings. The excess tax goodwill will be amortized and deducted for tax purposes over the remaining three year term. However, the excess tax goodwill has not been recorded for GAAP purposes and will not be realized 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 as of December 31, 2012.
	The Company is generally no longer subject to federal and state examinations for tax years prior to December 31, 2010.
	The Company had unrecognized tax benefits of approximately $0.3 million as of September 30, 2013 primarily associated with tax positions taken in a prior year. The Company incurred approximately $15,000 of income tax related interest expense and penalties related to uncertain tax positions during the three and nine months ended September 30, 2013. The Company had unrecognized tax benefits of approximately $0.1 million as of December 31, 2012.
	The Company utilizes a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon tax authority examination, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement.

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. 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 100,000 shares at $4.26 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 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 2008 and 2010 option grants was 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 2011 and 2013 option grant was 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 $2.79, $3.19, $3.76 and $2.54 per share for the options granted on June 18, 2013, January 14, 2011, March 18, 2010, and December 18, 2008, respectively, using the following assumptions:
		Grant Date

	Expected dividend yield	—		%	—		%	—		%	—		%
	Risk-free interest rate	1.33		%	2.31		%	2.79		%	1.43		%
	Expected volatility	75		%	60		%	61		%	61		%
	Expected life of option	6 years			6 years			6 years			6 years
	Grant date fair value	$	278,589		$	1,351,763		$	1,827,243		$	1,434,671
	On May 31, 2013, the Company entered into a separation agreement with its former Chief Financial Officer. In accordance with the terms of the separation agreement, and as permitted under the terms of the applicable option awards, the Company agreed that options awarded to the former Chief Financial Officer 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 the former Chief Financial Officer's 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 $0.4 million during the nine months ended September 30, 2013. Additionally, the separation agreement resulted in the forfeiture of 111,773 vested options issued under the March 18, 2010 option grant. The unvested portion of options previously awarded to the Company's Chief Financial Officer were also forfeited upon the termination of his employment.
	Restricted Shares of Common Stock
	On June 18, 2013, the Company granted to a key member of management 67,500 shares of restricted common stock with an aggregate grant date fair value of $287,550. One-third of the restricted shares are scheduled to vest on June 18, 2014, June 18, 2015 and June 18, 2016, respectively, and as such, no shares were vested as of September 30, 2013.
	On January 3, 2011, the Company granted to certain employees 166,943 shares of restricted common stock with an aggregate grant date fair value of $926,485. One half of these restricted shares vested on January 3, 2012 and the remainder vested on January 3, 2013, and as such, 166,943 were vested as of September 30, 2013.
	The Company recorded $0.1 million and $0.4 million of non-cash compensation expense associated with stock options and restricted shares in selling, general and administrative expenses for the three months ended September 30, 2013 and 2012, respectively. The Company recorded $0.7 million and $1.1 million of non-cash compensation expense associated with stock options and restricted shares in selling, general and administrative expenses for nine months ended September 30, 2013 and 2012, respectively. There was approximately $0.6 million and $0.5 million of total unrecognized compensation cost as of September 30, 2013 and December 31, 2012, respectively related to non-vested stock option and restricted share awards. The remaining cost is expected to be recognized ratably over the remaining respective vesting periods.

The Company’s stock repurchase program was suspended in May 2010 in conjunction with the launching of the cashless exercise warrant offer. Repurchases of our common stock and warrants were funded with cash flows of the business.

	Since December 2010, the Company has occupied 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. 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 the terms of such arrangement being reconsidered from time to time. The Company’s statements of operations for the three and nine months ended September 30, 2013 and 2012 each include approximately $23,000 and $69,000, 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 unsecured promissory notes mature in December 2013. The holders of the unsecured promissory notes are 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 recorded, net of an estimated allowance in connection with this liability.  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 $3.2 million and $1.9 million, respectively, as of September 30, 2013 and approximately $3.0 million and $2.0 million, respectively, as of December 31, 2012.

Reclassifications [Text Block]	Reclassifications
	Certain prior year amounts in the consolidated cash flow statements 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	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	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 13 to the consolidated financial statements regarding our segment information.
Recently Issued and Adopted 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.
