Organization Consolidation And Presentation Of Financial Statements [Abstract]
Nature of Operations	Note 1. Nature of Operations The Company is a leading provider of engineered lifting solutions. The Company reports in a single Manitex, Inc. (“Manitex”) markets a comprehensive line of boom trucks, truck cranes and sign cranes. Manitex’s boom trucks and crane products are primarily used for industrial projects, energy exploration and infrastructure development, including roads, bridges and commercial construction. Badger Equipment Company (“Badger”) is a manufacturer of specialized rough terrain cranes and material handling products. Badger primarily serves the needs of the construction, municipality and railroad industries. PM Oil and Steel S.p.A. (“PM” or “PM Group”), formerly known as PM Group S.p.A., is a leading Italian manufacturer of truck- mounted hydraulic knuckle boom cranes with a 50-year history of technology and innovation, and a product range spanning more than 50 models. PM is also a manufacturer of truck-mounted aerial platforms with a diverse product line and an international client base. Through its consolidated subsidiaries, PM Group has locations in Modena, Italy; Valencia, Spain; Arad, Romania; Chassieu, France; Buenos Aires, Argentina; Santiago, Chile; Singapore and Querétaro, Mexico. Manitex Valla S.r.L. (“Valla”) produces a full range of precision pick and carry industrial cranes using electric, diesel, and hybrid power options. Its cranes offer wheeled or tracked, and fixed or swing boom configurations, with special applications designed specifically to meet the needs of its customers. These products are sold internationally through dealers and into the rental distribution channel. Crane and Machinery, Inc. (“C&M”) is a distributor of the Company’s products as well as Terex Corporation’s (“Terex”) cranes. Crane and Machinery Leasing, Inc. (“C&M Leasing”) rents equipment manufactured by the Company as well as a limited amount of equipment manufactured by third parties. Although C&M is a distributor of Terex cranes, C&M’s primary business is the distribution of products manufactured by the Company. COVID-19 Pandemic The Company is continuing to closely monitor the spread and impact of the COVID-19 pandemic and is continually assessing its potential effects on our business and our financial performance as well as the businesses of our customers and vendors. The Company cannot predict the duration or severity of the COVID-19 pandemic, and we cannot reasonably estimate the financial impact the COVID-19 outbreak will have on our results and significant estimates going forward. Discontinued Operations A.S.V., LLC Prior to the quarter ended June 30, 2017, the Company owned a 51% interest in ASV Holdings, Inc., which was formerly known as A.S.V., LLC (“ASV” or “ASV Holdings”). ASV is located in Grand Rapids, Minnesota and manufactures a line of high-quality compact track and skid steer loaders. The products are used in site clearing, general construction, forestry, golf course maintenance and landscaping industries, with general construction being the largest. On May 11, 2017, in anticipation of an initial public offering, ASV Holdings converted from an LLC to a C-Corporation and the Company’s 51% interest was converted to 4,080,000 common shares of ASV. On May 17, 2017, in connection with its initial public offering, ASV Holdings sold 1,800,000 of its own shares and the Company sold 2,000,000 shares of ASV Holdings common stock and reduced its investment in ASV to a 21.2% interest. ASV was deconsolidated and was recorded as an equity investment starting with the quarter ended June 30, 2017. Periods ending before June 30, 2017 reflect ASV as a discontinued operation. In February 2018, the Company sold an additional 1,000,000 shares of ASV that it held which reduced the Company’s stake in ASV to approximately 11%. The Company ceased accounting for its investment in ASV under the equity method and began accounting for its investment as a marketable equity security. In September 2019, in connection with the sale of ASV to Yanmar American Corporation the Company received cash merger consideration for its remaining 1,080,000 shares of ASV and no longer has an investment in ASV. Manitex Sabre, Inc. (“Sabre”) On March 4, 2020, the Company’s Board of Directors approved the exploration by management of various strategic alternatives for Sabre, including the possibility of a transaction involving the sale of all or part of Sabre’s business and assets, to determine whether such a transaction would provide value to shareholders. The criterion of asset held for sale had been met and Sabre is reported as a discontinued operation. On August 21, 2020, the Company entered into an Asset Purchase Agreement to sell Manitex Sabre, Inc. to an affiliate of Super Steel, LLC for cash proceeds of $1.5 million, subject to certain adjustments based on closing date accounts receivable and inventory. In addition to the cash proceeds from sale of $1.5 million in cash received, the Company may receive a maximum royalty and earnout payments of approximately $2.9 million for years 2021 thru 2023 if certain revenue criteria are met. The Company will account for the contingent consideration as a gain in accordance with ASC 450. Under this approach, we will recognize the contingent consideration in earnings after the contingency is resolved. See Note 22 for additional discussion related to the sale of Sabre’s business and assets.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 3. Summary of Significant Accounting Policies The summary of significant accounting policies of Manitex International, Inc. is presented to assist in understanding the Company’s financial statements. The financial statements and notes are representations of the Company’s management who is responsible for their integrity and objectivity. These accounting policies conform to generally accepted accounting principles and have been consistently applied in the preparation of the financial statements. Cash and Cash Equivalents —For purposes of the statement of cash flows, the Company considers all short-term securities purchased with maturity dates of three months or less to be cash equivalents. The cash in the Company's U.S. banks (primarily CIBC) is not fully insured by the FDIC due to the statutory limit of $250. Restricted Cash —Certain of the Company’s lending arrangements require the Company to post collateral or maintain minimum cash balances in escrow. These cash amounts are reported as current assets on the balance sheets based on when the cash will be contractually released. Total restricted cash was $240 and $217 at December 31, 2020 and 2019, respectively. Revenue Recognition —Revenue is recognized when obligations under the terms of the contract with our customer are satisfied; generally, this occurs with the transfer of control of our equipment, parts or installation services (typically completed within one day), which occurs at a point in time. Equipment can be redirected during the manufacturing phase such that over time revenue recognition is not appropriate. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Our contracts are non-cancellable and returns are only allowed in limited instances. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. The expected costs associated with our base warranties continue to be recognized as expense when the products are sold and do not constitute a separate performance obligation. For instances where equipment and installation services are sold together, the Company accounts for the equipment and installation services separately. The consideration (including any discounts) is allocated between the equipment and installation services based on their stand-alone selling prices. The stand-alone selling prices are determined based on the prices at which the Company separately sells the equipment . In some instances, the Company fulfills its obligations and bills the customer for the work performed but does not ship the goods until a later date. These arrangements are considered bill-and-hold transactions. In order to recognize revenue on the bill-and-hold transactions, the Company ensures the customer has requested the arrangement, the product is identified separately as belonging to the customer, the product is ready for shipment to the customer in its current form, and the Company does not have the ability to direct the product to a different customer. A portion of the transaction price is not allocated to the custodial services due to the immaterial value assigned to that performance obligation. Payment terms offered to customers are defined in contracts and purchase orders and do not include a significant financing component. At times, the Company may offer discounts which are considered variable consideration however, the Company applies the constraint guidance when determining the transaction price to be allocated to the performance obligations. Allowance for Doubtful Accounts —Accounts receivable are stated at the amounts the Company’s customers are invoiced and do not bear interest. The Company has adopted a policy consistent with U.S. GAAP for the periodic review of its accounts receivable to determine whether the establishment of an allowance for doubtful accounts is warranted based on the Company’s assessment of the collectability of the accounts. The Company established an allowance for bad debt of $2.6 million and $2.8 million at December 31, 2020 and 2019, respectively. The Company also has in some instances a security interest in its accounts receivable until payment is received. Property, Equipment and Depreciation —Property and equipment are stated at cost or the fair market value at date of acquisition for property and equipment acquired in connection with the acquisition of a company. Depreciation of property and equipment is provided over the following useful lives: Asset Category Depreciable Buildings 12 –33 years Machinery and equipment 3 – 15 years Furniture and fixtures 3 – 10 years Leasehold improvements 5 Motor Vehicles 3 Computer software 3 Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred. Depreciation of property, and equipment is calculated using the straight-line method over the estimated useful lives of the assets. Depreciation expense for the years ended December 31, 2020 and 2019 was $2,011 and $2,071, respectively. Other Intangible Assets —The Company capitalizes certain costs related to patent technology. Additionally, a substantial portion of the purchase price related to the Company’s acquisitions has been assigned to patents or unpatented technology, trade name, customer Goodwill — Goodwill, representing the difference between the total purchase price and the fair value of assets (tangible and intangible) and liabilities at the date of acquisition, is reviewed for impairment annually, and more frequently as circumstances warrant, and written down only in the period in which the recorded value of such assets exceed their fair value. The Company does not amortize goodwill. Under “ASC 350”, entities are provided with the option of first performing a qualitative assessment on none, some, or all of its reporting units to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If after completing a qualitative analysis, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value a quantitative analysis is required. The Company evaluates its consolidated goodwill using the quantitative two step approach. The first step used to identify potential impairment involves comparing the reporting unit’s estimated fair value to its carrying value, including goodwill. During the first step testing, the Company evaluates goodwill for impairment using a business valuation method, which is calculated as of a measurement date by determining the present value of debt-free, after-tax projected future cash flows, discounted at the weighted average cost of capital of a hypothetical third-party buyer. The market approach was also considered in evaluating the potential for impairment by calculating fair value based on multiples of earnings before interest, taxes, depreciation and amortization (EBITDA) of comparable, publicly traded companies. The Company also observed implied EBITDA multiples from relatively recent merger and acquisition activity in the industry, which was used to test the reasonableness of the results. The second step of the process involves the calculation of an implied fair value of goodwill for each reporting unit for which step one indicated impairment. The implied fair value of goodwill is determined by measuring the excess of the estimated fair value of the reporting unit over the estimated fair values of the individual assets, liabilities and identifiable intangibles as if the reporting unit was being acquired in a business combination. If the implied fair value of goodwill exceeds the carrying value of goodwill assigned to the reporting unit, there is no impairment. If the carrying value of goodwill assigned to a reporting unit exceeds the implied fair value of the goodwill, an impairment charge is recorded for the excess. An impairment loss cannot exceed the carrying value of goodwill assigned to a reporting unit and the subsequent reversal of goodwill impairment losses is not permitted. The determination of fair value requires the Company to make significant estimates and assumptions. These estimates and assumptions primarily include, but are not limited to, revenue growth and operating earnings projections, discount rates, terminal growth rates, and required capital expenditure projections. In the event the Company determines that goodwill is impaired in the future the Company would need to recognize a non-cash impairment charge. The Company performed its annual impairment assessment as of March 31, 2020, prior to its October 1, 2020 annual measurement date. The valuation analysis was performed at March 31, 2020 due to the Company identifying a triggering event. Subsequently, a step 0 analysis was performed at December 31, 2020 indicating no impairment. In 2019, Impairment of Long-Lived Assets — The Company’s policy is to assess the realizability of its long-lived assets, including intangible assets, and to evaluate such assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets (or group of assets) may not be recoverable. Impairment is determined to exist if the estimated future undiscounted cash flows are less than the carrying value. Future cash flow projections include assumptions for future sales levels, the impact of cost reduction programs, and the level of working capital needed to support each business. The amount of any impairment then recognized would be calculated as the difference between the estimated fair value and the carrying value of the asset. The Company recognized $6.7 million in impairment related to tradenames, goodwill and customer relationships for the year ended December 31, 2020. The Company recognized $1.5 million in impairment related to tradenames, goodwill and customer relationships for the year ended December 31, 2019. Inventory —Inventory consists of stock materials and equipment stated at the lower of cost (first in, first out) or net realizable value. All equipment classified as inventory is available for sale. The company records excess and obsolete inventory reserves. The estimated reserve is based upon specific identification and/or historical experience of excess or obsolete inventories. Selling, general and administrative expenses are expensed as incurred and are not capitalized as a component of inventory. Accounting for Paycheck Protection Program —The Company has elected to account for the Paycheck Protection Program (PPP) loan as a government grant and as such, the loan was recorded as a deferred income liability on the balance sheet. The Company has applied for forgiveness of the loan. The offset will be recorded against the related expense on the income statement. Foreign Currency Translation and Transactions —The financial statements of the Company’s non-U.S. subsidiaries are translated using the current exchange rate for assets and liabilities and the weighted-average exchange rate for the year for income and expense items. Resulting translation adjustments are recorded to accumulated other comprehensive income (OCI) as a component of shareholders’ equity The Company converts receivables and payables denominated in other than the Company’s functional currency at the exchange rate as of the balance sheet date. The resulting transaction exchange gains or losses, except for certain transaction gains or loss related to intercompany receivable and payables, are included in other income and expense. Transaction gains and losses related to intercompany receivables and payables not anticipated to be settled in the foreseeable future are excluded from the determination of net income and are recorded as a translation adjustment (with consideration to the tax effect) to accumulated other comprehensive income (OCI) as a component of shareholders’ equity. Derivatives—Forward Currency Exchange Contracts —When the Company enters into forward currency exchange contracts it does so such that the exchange gains and losses on the assets and liabilities that are being hedged, which are denominated in a currency other than the reporting units’ functional currency, would be offset by the changes in the market value of the forward currency exchange contracts it holds. The forward currency exchange contracts that the Company has to offset existing assets and liabilities denominated in other than the reporting units’ functional currency have been determined not to be considered a hedge. The Company records the forward currency exchange contracts at its market value with any associated gain or loss being recorded in current earnings. Both realized and unrealized gains and losses related to forward currency contracts are included in current earnings and are reflected in the Consolidated Statements of Operations in the other income expense section on the line titled foreign currency transaction loss. Research and Development Expenses — The Company expenses research and development costs, as incurred. For the periods ended December 31, 2020 and 2019 expenses were $3,227 and $2,714, respectively. Advertising —Advertising costs are expensed as incurred and were $ and $ 965 for the years ended December 31, 20 20 and 201 9 , respectively. Retirement Benefit Costs and Termination Benefits —Payments to defined contribution retirement benefit plans are recognized as an expense when employees have rendered service entitling them to the contributions. Employees in Italy are entitled to Trattamento di Fine Rapporto (“TFR”), commonly referred to as an employee leaving indemnity, which represents deferred compensation for employees in the private sector. Under Italian law, an entity is obligated to accrue for TFR on an individual employee basis payable to each individual upon termination of employment (including both voluntary and involuntary dismissal). The expense is recognized in the personnel costs (SG&A or COGS) in the Consolidated Statements of Operations and the accrual is recorded in other long-term liability in the Consolidated Balance Sheets. Litigation Claims —In determining whether liabilities should be recorded for pending litigation claims, the Company must assess the allegations and the likelihood that it will successfully defend itself. When the Company believes it is probable that it will not prevail in a particular matter, it will then record an estimate of the amount of liability based, in part, on advice of legal counsel Shipping and Handling —The Company records the amount of shipping and handling costs billed to customers as revenue. The cost incurred for shipping and handling is included in the cost of sales. Adoption of Highly Inflationary Accounting in Argentina — GAAP guidance requires the use of highly inflationary accounting for countries whose cumulative three-year inflation exceeds 100 percent. In the second quarter of 2018, published inflation indices indicated that the three-year cumulative inflation in Argentina exceeded 100 percent, and as of July 1, 2018, we elected to adopt highly inflationary accounting for our subsidiary in Argentina (“PM Argentina”). Under highly inflationary accounting, PM Argentina’s functional currency became the Euro (its parent company’s reporting currency), and its income statement and balance sheet have been measured in Euros using both current and historical rates of exchange. The effect of changes in exchange rates on peso-denominated monetary assets and liabilities has been reflected in earnings in other (income) and expense, net and was not material. As of December 31, 2020, PM Argentina had a small net peso monetary position. Net sales of PM Argentina were less than 5 percent of our consolidated net sales for the years ended December 31, 2020 and 2019, respectively. Income Taxes — On March 27, 2020, the “Coronavirus Aid, Relief and Economic Security (CARES) Act” was enacted. The CARES Act, among other things, includes provisions relating to net operating loss carrybacks, alternative minimum tax credit refunds, a modification to the net interest deduction limitations and a technical correction to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company’s consolidated financial statements for the year ended December 31, 2020. The Company accounts for income taxes under the provisions of ASC 740 “Income Taxes,” which requires recognition of income taxes based on amounts payable with respect to the current year and the effects of deferred taxes for the expected future tax consequences of events that have been included in the Company’s financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial accounting and tax basis of assets and liabilities, as well as for operating losses and tax credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are recorded to reduce deferred tax assets when it is more-likely-than-not a tax benefit will not be realized. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income prior to the expiration of any net operating loss carryforwards. See Note 15, Income Taxes, for further details. The Jobs Act also establishes Global Intangible Low-Taxed Income (“GILTI”) provisions that impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The Company has elected to recognize GILTI as a period cost as incurred, therefore there are no deferred taxes recognized for basis differences that are expected to impact the amount of the GILTI inclusion upon reversal. ASC 740 also prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, as well as guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company records interest and penalties related to income tax matters in the provision for income taxes. Accrued Warranties —Warranty costs are accrued at the time revenue is recognized. The Company’s products are typically sold with a warranty covering defects that arise during a fixed period of time. The specific warranty offered is a function of customer expectations and competitive forces. A liability for estimated warranty claims is accrued at the time of sale. The liability is established using historical warranty claim experience. The current provision may be adjusted to take into account unusual or non-recurring events in the past or anticipated changes in future warranty claims. Adjustments to the initial warranty accrual are recorded if actual claim experience indicates that adjustments are necessary. As of December 31, 2020 and 2019, accrued warranties were $1,292 and $1,604, respectively. Debt Issuance Costs —Debt issuance costs incurred in securing the Company’s financing arrangements are capitalized and amortized over the term of the associated debt. Deferred financing costs associated with long-term debt are presented in the balance sheet as direct deduction from the carrying amount of that debt liability, consistent with debt discount. Deferred financing costs associated with revolving lines of credit are included with other long-term assets on the Company’s Consolidated Balance Sheets. Sale and Leaseback —In accordance with ASC 842-10 Sales-Leaseback Transactions, the Company has recorded a deferred gain in relationship to the sale and leaseback of one of the Company’s operating facilities and on certain equipment. As such, the gains have been deferred and are being amortized on a straight- line basis over the life of the leases. Computation of EPS —Basic Earnings per Share (“EPS”) was computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. The number of shares related to options, warrants, restricted stock, convertible debt and similar instruments included in diluted EPS (“EPS”) is based on the “Treasury Stock Method” prescribed in ASC 260-10, Earnings per Share. This method assumes the theoretical repurchase of shares using proceeds of the respective stock option or warrant exercised, and for restricted stock, the amount of compensation cost attributed to future services which has not yet been recognized, and the amount of current and deferred tax benefit, if any, that would be credited to additional paid in capital upon the vesting of the restricted stock, at a price equal to the issuer’s average stock price during the related earnings period. Accordingly, the number of shares includable in the calculation of EPS in respect of the stock options, warrants, restricted stock, convertible debt, and similar instruments is dependent on this average stock price and will increase as the average stock price increases. Stock Based Compensation —In accordance with ASC 718 Compensation-Stock Compensation, share-based payments to employees, including grants of restricted stock units, are measured at fair value as of the date of grant and are expensed in the Consolidated Statements of Operation over the service period (generally the vesting period). Comprehensive Income —Comprehensive income includes, in addition to net earnings, other items that are reported as direct adjustments to shareholder’s equity. Currently, the comprehensive income adjustment required for the Company is a foreign currency translation adjustment, the result of consolidating its foreign subsidiary. Business Combinations —The Company accounts for acquisitions in accordance with guidance found in ASC 805, Business Combinations. The guidance requires consideration given, including contingent consideration, assets acquired, and liabilities assumed to be valued at their fair market values at the acquisition date. The guidance further provides that: (1) in-process research and development will be recorded at fair value as an indefinite-lived intangible asset; (2) acquisition costs will generally be expensed as incurred, (3) restructuring costs associated with a business combination will generally be expensed subsequent to the acquisition date; and (4) changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally will affect income tax expense. The Company records any excess of purchase price over fair value of assets acquired, including identifiable intangibles and liabilities assumed be recognized as goodwill. Reclassification —A reclassification to properly reflect a decrease in long-term liabilities of discontinued operations of $0.4 million, an increase in deferred tax liability of $0.3 million, and a decrease in deferred tax asset of $0.1 million was recorded in the fourth quarter of 2020 for the year ended December 31, 2019.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 6. Fair Value Measurements The following tables set forth the Company’s financial assets and liabilities that were accounted for at fair value by level with the fair value hierarchy. As required by ASC 820-10, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Except as noted the below assets and liabilities are valued at fair market on a recurring basis. The following is a summary of items that the Company measured at fair value during the periods: Fair Value at December 31, 2020 Level 1 Level 2 Level 3 Total Liabilities: Valla contingent consideration $ — $ — $ 224 $ 224 Forward currency exchange contracts — 267 — 267 Total liabilities at fair value $ — $ 267 $ 224 $ 491 Fair Value at December 31, 2019 Liabilities: PM contingent liabilities $ — $ — $ 314 $ 314 Valla contingent consideration — — 205 205 Forward currency exchange contracts — 99 — 99 Total liabilities at fair value $ — $ 99 $ 519 $ 618 Fair Value Measurements Using Significant Unobservable Inputs (level 3) Liabilities: PM Contingent Liability Valla Contingent Consideration Total Balance at December 31, 2019 $ 314 $ 205 $ 519 Effect of change in exchange rates — 19 19 Change in contingent liability consideration (314 ) — (314 ) Balance at December 31, 2020 $ — $ 224 $ 224 In 2019, the fair value of PM contingent liabilities, a Level 3 item, was based on an option pricing framework, more specifically, a Monte Carlo simulation. The original fair value of Valla contingent consideration was also determined by using the Monte Carlo option pricing framework simulation at the acquisition date. The Company has qualitatively evaluated the Valla contingent liability from the date of acquisition. The carrying value of the amounts reported in the Consolidated Balance Sheets for cash, accounts receivable, accounts payable and short-term variable debt, including any amounts outstanding under the Company’s revolving credit facilities and working capital borrowing, approximate fair value due to the short periods during which these amounts are outstanding. The book and fair value of the Company’s term debt was $16,532 for the year ended December 31, 2020, and $22,931 for the year ending December 31, 2019. The book and fair value of the Company’s capital leases was $4,565 and $5,592 for the year ended December 31, 2020, respectively and $5,060 and $6,295 for the year ending December 31, 2019, respectively. There is no difference between the book value and the fair value for amount recorded in connection with the liability recorded for a long-term legal settlement, which was $765 and $809 for the years ending December 31, 2020 and 2019, respectively. Fair Value Measurements ASC 820-10 classifies the inputs used to measure fair value into the following hierarchy: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 - Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity) Fair value of the forward currency contracts is determined on the last day of each reporting period using observable inputs, which are supplied to the Company by the foreign currency trading operation of its bank and are Level 2 items.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 7. Derivative Financial Instruments The Company’s risk management objective is to use the most efficient and effective methods available to us to minimize, eliminate, reduce or transfer the risks which are associated with fluctuation of exchange rates between the Euro, Chilean Peso and the U.S. dollar. Forward Currency Contracts The Company enters into forward currency exchange contracts such that the exchange gains and losses on the assets and liabilities denominated in other than the reporting units’ functional currency would be offset by the changes in the market value of the forward currency exchange contracts it holds. The forward currency exchange contracts that the Company has to offset existing assets and liabilities denominated in other than the reporting units’ functional currency have been determined not to be considered a hedge under ASC 815-10. The Company records the forward currency exchange contracts at its market value with any associated gain or loss being recorded in current earnings. Both realized and unrealized gains and losses related to forward currency contracts are included in current earnings and are reflected in the Consolidated Statements of Operations in the other income expense section on the line titled foreign currency transaction gains (losses). Items denominated in other than a reporting unit functional currency include certain intercompany receivables due from the Company’s Italian subsidiaries and accounts receivable and accounts payable of our Italian subsidiaries and their subsidiaries. PM Group has an intercompany receivable denominated in Euros from its Chilean subsidiary. At December 31, 2020, the Company had entered into two forward currency exchange contracts that mature on January 8, 2021. Under the contract the Company is obligated to sell 2,900,000 Chilean pesos for 3,140 euros. The Company has a second contract which obligates the Company to sell 160,000 Chilean pesos for $205. The purpose of the forward contract is to mitigate the income effect related to this intercompany receivable that results with a change in exchange rate between the Euro and the Chilean peso. The following table provides the location and fair value amounts of derivative instruments that are reported in the Consolidated Balance Sheet as of December 31, 2020 and 2019: Total derivatives not designated as a hedge instrument Fair Value As of December 31, Balance Sheet Location 2020 2019 Liabilities Derivatives Foreign currency Exchange Contracts Accrued expense $ 267 $ 99 Total derivative liabilities $ 267 $ 99 The following tables provide the effect of derivative instruments on the Consolidated Statement of Operations for 2020 and 2019: Derivatives not designated as Hedge Instrument Location of gain or (loss) recognized in Income Statement Years ended December 31, 2020 2019 Forward currency contracts Foreign currency transaction losses $ (167 ) $ (191 ) Interest rate swap contracts Interest income — 2 Total derivatives loss $ (167 ) $ (189 ) During 2020 and 2019, there were no forward currency contracts designated as cash flow hedges. As such, all gains and loss related to forward currency contracts during 2020 and 2019 were recorded in current earnings and did not impact other comprehensive income.

The valuation analysis was performed at March 31, 2020 due to the Company identifying a triggering event. Subsequently, a step 0 analysis was performed at December 31, 2020 indicating no impairment. As of the valuation date, the global economy and the financial markets were experiencing severe adverse effects from the coronavirus disease (COVID-19) pandemic. While uncertainty remains as to its ultimate impact and duration, the COVID-19 pandemic is causing tremendous hardships globally and adversely impacting global and financial market conditions. At March 31, 2020, the Company considered a decrease in its market capitalization to be a triggering event and as such a valuation analysis was performed and goodwill and intangible assets were determined to be impaired, and as such non-cash impairment charges were made to selling, general and administrative expense and shown separately on the Consolidated Statement of Operations as impairment of intangibles. In order to more closely align the estimated fair values of our reporting units to our overall market capitalization, an increase to our risk premium utilized within our discounted cash flows analysis was applied, resulting in an impairment charge to goodwill and intangible assets at our PM reporting unit in the amount of $6.6 million and $0.1 million, respectively. At September 30, 2019, the Company considered declining revenue and profitability along with missed projections and a decrease in its market capitalization to be a triggering event and as such a valuation analysis was performed and goodwill and intangible assets were determined to be impaired, and as such non-cash impairment charges were made to selling, general and administrative expense and shown separately on the income statement as impairment of intangibles. Goodwill was impaired at PM/Valla in the amount of $0.3 million. At December 31, 2019, intangible assets were impaired at PM/Valla in the amount of $1.2 million. While there was no additional impairment of goodwill recognized as a result of the 2020 annual impairment test, a reasonably possible unexpected deterioration in financial performance or adverse change in earnings may result in a further impairment.

Debt Disclosure [Abstract]
Revolving Term Credit Facilities and Debt	Note 12. Revolving Term Credit Facilities and Debt U.S. Credit Facilities At December 31, 2020, the Company and its U.S. subsidiaries have a Loan and Security Agreement, as amended, (the “Loan Agreement”) with CIBC Bank USA (“CIBC”), formerly known as “The Private Bank and Trust Company”. The Loan Agreement provides a revolving credit facility with a maturity date of July 20, 2023. The aggregate amount of the facility is $30 million. The maximum borrowing available to the Company under the Loan Agreement is limited to: (1) 85% of eligible receivables; plus (2) 50% of eligible inventory valued at the lower of cost or net realizable value subject to a $20 million limit; plus (3) 80% of eligible used equipment, as defined, valued at the lower of cost or market subject to a $2 million limit; plus (4) 50% of eligible Mexico receivables (as defined) valued at the lower of cost or net realizable value subject to a $0.4 million limit. The Loan Agreement provides that the Company can opt to pay interest on the revolving credit at either a base rate plus a spread, or a LIBOR rate plus a spread. The base rate and the LIBOR rate are subject to a floor of 0.50%. The LIBOR spread ranges from 1.75% to 2.25% depending on the Adjusted Excess Availability. Funds borrowed under the LIBOR option can be borrowed for periods of one, two, or three months and are limited to four LIBOR contracts outstanding at any time. In addition, a fee of 0.375% is applied for the unused portion of the revolving facility and is payable monthly. The Loan Agreement subjects the Company and its domestic subsidiaries to a quarterly EBITDA covenant if the Company has less than $15 million of Adjusted Excess Availability (as defined). The minimum quarterly EBITDA covenant is $0.5 million for the quarter ending March 31, 2021 and builds to $1.5 million on a trailing 3 quarter basis starting with the quarter ending September 30, 2021 and then maintains at $1.5 million on a trailing twelve-month basis for the quarter ending December 31, 2021. Additionally, the Company and its domestic subsidiaries are subject to a Fixed Charge Coverage ratio if the Company has less than $15 million of adjusted excess availability (as defined) and $5 million or more of outstanding borrowings under the revolving facility. The Fixed Charge Coverage ratio is 1.10 to 1.00 measured on a trailing 3 quarter basis through quarter ending March 31, 2021 and then based upon a trailing month to month basis beginning with the quarter ending June 30, 2021 through the end of the term of the agreement. At the end of a quarter, if there is less than $15 million of excess availability and more than $5 million in outstanding borrowings, then covenant testing is required. The Loan Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company’s ability to, among other things, incur additional indebtedness, grant liens, merge or consolidate, dispose of assets, make investments, make acquisitions, pay dividends or make distributions, repurchase stock, in each case subject to customary exceptions for a credit facility of this size. The Company was in compliance with its covenants as of December 31, 2020. The Loan Agreement has a Letter of Credit facility of $3 million, which is fully reserved against availability. As of December 31, 2020, the outstanding Letters of Credit were $0.2 million which is offset against availability under the revolving facility. Note Payable—Bank At December 31, 2020, the Company has a $237 term note payable to a bank. The note dated November 13, 2020 had an original principal amount of $289 and an annual interest rate of 5.81%. Proceeds from the note were used to pay annual premiums for certain insurance policies carried by the Company.

PM Group Short-Term Working Capital Borrowings At December 31, 2020 and 2019, respectively, PM Group had established demand credit and overdraft facilities with five banks in Italy, one bank in Spain and eleven banks in South America. Under the facilities, as of December 31, 2020 and 2019 respectively, PM Group can borrow up to approximately €20,550 ($25,133) and €21,337 ($23,955) At December 31, 2020, the Italian banks had advanced PM Group €10,551 ($12,904). There were no advances to PM Group from the Spanish bank, and the South American banks had advanced PM Group €98 ($120). PM Group Term Loans At December 31, 2020, PM Group has a €5,752 ($7,035) term loan with Davy Global Fund Management, an Irish fund that purchased the debt from BPER, an Italian bank. The term loan is split into a note and a balloon payment and is secured by PM Group’s common stock. The term loan is charged interest at a fixed rate of 3.5%. The note is payable in annual installments of principal, €513 for 2021, €531 for 2022, €549 for 2023, €569 for 2024, and €588 for 2025. The balloon payment is payable in a single payment of €3,002 in 2026. At December 31, 2019, the note and balloon payment had an outstanding principal balance of €6,492 ($7,289) for BPER and €3,002 ($3,439) for Unicredit, respectively. An adjustment in the purchase accounting to value the non-interest- bearing debt at its fair market value was made. At March 6, 2018 it was determined that the fair value of the debt was €480 or $550 less than the book value. This reduction is not reflected in the above descriptions of PM debt. This discount is being amortized over the life of the debt and being charged to interest expense. As of December 31, 2020, and 2019 respectively, the remaining balance was €114 ($140) and €281 ($315) and has been offset to the debt. At December 31, 2020, PM Group has unsecured borrowings with an Italian bank (MPS) and an Irish fund (Davy Global Fund Management) totaling totaling €7,225 ($8,836).

PM Group is subject to certain financial covenants including maintaining (1) Net debt to EBITDA, (2) Net debt to equity, and (3) EBITDA to net financial charges ratios. The covenants are measured on a semi-annual basis. The Company was in compliance with the loan covenants at December 31, 2020 and 2019. Autogru PM RO, a subsidiary of PM Group, had an outstanding note during 2020 and 2019 that was payable in 60 monthly principal installments of €8 ($9), October 2020 At December 31, 2020 and 2019, Autogru PM had a term note with an outstanding principal balance of €116 ($142) and €218 ($245), respectively.

The Company approached Unicredit to paydown the entire debt obligation in a cash offer at a discount. On July 20, 2020, the Company paid off the entire PM term and unsecured debt of €4,960 ($6,269) with Unicredit at a 15% discount to its face value which resulted in a gain of €533 ($595) recorded in other income. In additional, accrued interest from April 1, 2020 to July 19, 2020 was forgiven by the bank. The above PM facilities included a put and call options agreement with BPER to, among other things, extend the exercise of the options until the approval of PM Group’s financial statements for the 2021 fiscal year and permit the assignment of certain subordinated receivables to the Company. The fair market value of this liability is subject to revaluation on a recurring basis and as such, the Company reversed the €280 ($334) liability as of December 31, 2020.

Leases [Abstract]
Leases	Note 13. Leases The Company leases certain warehouses, office space, machinery, vehicles, and equipment. Leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. The Company is not aware of any variable lease payments, residual value guarantees, covenants or restrictions imposed by the leases. Most leases include one or more options to renew, with renewal terms that can extend the lease term. The exercise of lease renewal options is at our sole discretion. The depreciable life of assets is limited by the expected lease term for finance leases. If there was a rate explicit in the lease, this was the discount rate used. For those leases with no explicit or implicit interest rate, an incremental borrowing rate was used. The weighted average remaining useful life for operating and finance leases was 5 and 7 years, respectively. The weighted average discount rate for operating and finance leases was 5.7% and 12.5% respectively.

Certain real estate leases include one or more options to renew. The exercise of lease renewal options is at the Company's sole discretion. Options to extend the lease are included in the lease term when it is reasonably certain the Company will exercise the option. The Company also has production equipment, office equipment and vehicles under operating leases. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option that is reasonably certain of exercise. Certain leases include rental payments adjusted periodically for inflation. The lease agreements do not contain any material residual value guarantee or material restrictive covenants. Bridgeview Facility The Company leased its 40,000 sq. ft. Bridgeview facility from an entity controlled by Mr. David Langevin, the Company’s Executive Chairman and CEO, through December 31, 2020. This facility is now owned by an unaffiliated third party. See Note 19, Transactions between the Company and Related Parties for further information.

Convertible Notes

Convertible Notes	12 Months Ended

Debt Disclosure [Abstract]
Convertible Notes	Note 14. Convertible Notes Related Party On December 19, 2014, the Company issued a subordinated convertible debenture with a $7,500 face amount payable to Terex, a related party. The convertible debenture is subordinated, carries a 5% per annum coupon, and is convertible into Company common stock at a conversion price of $13.65 per share or a total of 549,451 shares, subject to customary adjustment provisions. The debenture matured on December 19, 2020. From and after the third anniversary of the original issuance date, the Company may redeem the convertible debenture in full (but not in part) at any time that the last reported sale price of the Company’s common stock equals at least 130% of the Conversion Price (as defined in the debenture) for at least 20 of any 30 consecutive trading days. Following an election by the holder to convert the debenture into common stock of the Company in accordance with the terms of the debenture, the Company has the discretion to deliver to the holder either (i) shares of common stock, (ii) a cash payment, or (iii) a combination of cash and stock. In accounting for the issuance of the note, the Company separated the note into liability and equity components. The carrying amount of the liability component was calculated by measuring the estimated fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the face value of the Note as a whole. The excess of the principal amount of the liability component over its carrying amount (“debt discount”) is amortized to interest expense over the term of the note using the effective interest method with an effective interest rate of 7.5 percent per annum. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. Additionally, in connection with the transaction a $321 deferred tax liability was established and was recorded as a deduction to paid in capital. The deferred tax liability was recognized as the excess of the principal amount being amortized and charged to interest expenses is not tax deductible. As of December 31, 2020, the Company paid off the remaining principal balance of the note. As of December 31, 2019, the note had a remaining principal balance of $7,323 and an unamortized discount of $177. Perella Notes On January 7, 2015, the Company entered into a Note Purchase Agreement (the “Perella Note Purchase Agreement”) with MI Convert Holdings LLC (which is owned by investment funds constituting part of the Perella Weinberg Partners Asset Based Value Strategy) and Invemed Associates LLC (together, the “Investors”), pursuant to which the Company agreed to issue $15,000 in aggregate principal amount of convertible notes due January 7, 2021 (the “Perella Notes”) to the Investors. The Notes are subordinated, carry a 6.50% per annum coupon, and are convertible, at the holder’s option, into shares of Company common stock, based on an initial conversion price of $15.00 per share, subject to customary adjustments. Following an election by the holder to convert the debenture into common stock of the Company in accordance with the terms of the debenture, the Company has the discretion to deliver to the holder either (i) shares of common stock, (ii) a cash payment, or (iii) a combination of cash and stock. Upon the occurrence of certain fundamental corporate changes, the Perella Notes are redeemable at the option of the holders of the Perella Notes. The Perella Notes are not redeemable at the Company’s option prior to the maturity date, and the payment of principal is subject to acceleration upon an event of default. The issuance of the Perella Notes by the Company was made in reliance upon the exemptions from registration provided by Rule 506 and Section 4(2) of the Securities Act of 1933. In accounting for the issuance of the note, the Company separated the note into liability and equity components. The carrying amount of the liability component was calculated by measuring the estimated fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the face value of the Note as a whole. The excess of the principal amount of the liability component over its carrying amount (“debt discount”) is amortized to interest expense over the term of the note using the effective interest method with an effective interest rate of 7.5 percent per annum. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. Additionally, in connection with the transaction a $257 deferred tax liability was established and was recorded as a deduction to paid in capital. The deferred tax liability was recognized as the excess of the principal amount being amortized and charged to interest expense and is not tax deductible. As of December 31, 2020, the Company paid off the remaining principal balance of the note. As of December 31, 2019, the note had a remaining principal balance of $14,858 (less $98 debt issuance cost for a net debt $14,760) and an unamortized discount of $142. The difference between this amount and the amount initially recorded represents $572 of discount amortization.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Note 15. Income Taxes On March 27, 2020, the “Coronavirus Aid, Relief and Economic Security (CARES) Act” was enacted. The CARES Act, among other things, includes provisions relating to net operating loss carrybacks, alternative minimum tax credit refunds, a modification to the net interest deduction limitations and a technical correction to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company’s consolidated financial statements for the year ended December 31, 2020. The Jobs Act establishes Global Intangible Low-Taxed Income (“GILTI”) provisions that impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The Company has elected to recognize GILTI as a period cost as incurred; therefore, there are no deferred taxes recognized for basis differences that are expected to impact the amount of the GILTI inclusion upon reversal. The Company’s assertion to indefinitely reinvest its foreign earnings remains unchanged despite the US taxation of its undistributed foreign earnings and new tax law, which includes a 100% dividend received deduction. This means that future distributions of foreign earnings will generally not be taxable in the US. However, upon remittance of these earnings, the Company would be subject to withholding tax, US tax on foreign currency gains and losses related to previously taxed earnings, and some state income tax. It is not practicable to estimate the tax impact of the reversal of the outside basis difference, or the repatriation of cash due to the complexity associated with these calculations . Information pertaining to the Company’s income before income taxes from continuing operations is as follows: Years ended December 31, 2020 2019 (Loss) income before income taxes: Domestic $ (6,566 ) $ 6,861 Foreign (5,479 ) (4,015 ) Total net (loss) income before income taxes $ (12,045 ) $ 2,846 Information pertaining to the Company’s provision for income taxes for continuing operations is as follows: Years ended December 31, 2020 2019 Expense (benefit) for income taxes: Current: Federal $ (28 ) $ (33 ) State and local (112 ) 19 Foreign 488 510 348 496 Deferred: Federal 32 31 State and local 187 159 Foreign 107 2,105 326 2,295 Total expense for income taxes $ 674 $ 2,791 Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows: Year ended December 31, 2020 2019 Deferred tax assets: Accrued expenses $ 532 $ 906 Inventory 1,924 2,326 Other liabilities 1,465 930 Deferred gain 137 172 Net operating loss carryforwards 5,473 3,498 Tax credit carryforwards 1,341 1,317 Capital loss carryforwards 238 440 Unrealized foreign currency loss 110 97 Interest expense 3,566 3,537 Property, plant and equipment 296 688 Total deferred tax asset 15,082 13,911 Deferred tax liabilities: Intangibles 3,696 2,926 Discount on convertible notes — 73 Deferred State Income Tax 396 402 Debt 2,382 2,197 Total deferred tax liability 6,474 5,598 Valuation allowance (9,694 ) (8,943 ) Net deferred tax (liability) asset $ (1,086 ) $ (630 ) The Company made a downward adjustment to its U.S. net operating loss carryforward disclosed in the deferred tax assets and liabilities table in the comparable reporting period by approximately $1.3 million with an offsetting adjustment to the valuation allowance. In assessing the realizability of deferred tax assets, we evaluate whether it is more likely than not (more than 50%) that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income in those periods in which temporary differences become deductible and/or net operating losses can be utilized. We assess all positive and negative evidence when determining the amount of the net deferred tax assets that are more likely than not to be realized. This evidence includes, but is not limited to, prior earnings history, scheduled reversal of taxable temporary differences, tax planning strategies and projected future taxable income. Significant weight is given to positive and negative evidence that is objectively verifiable. As required by the authoritative guidance on accounting for income taxes, the Company evaluates the realizability of deferred tax assets on a jurisdictional basis at each reporting date. Accounting for income taxes requires that a valuation allowance be established when it is more likely than not that all or a portion of the deferred tax assets will not be realized. In circumstances where there is sufficient negative evidence indicating that the deferred tax assets are not more likely than not realizable, we establish a valuation allowance. Any further increases or decreases in the valuation allowance could have an unfavorable or favorable impact on our income tax provision and net income in the period in which such determination is made. As of December 31, 2020, the Company had U.S. federal and foreign net operating loss carryforwards of approximately $15.2 million. U.S. net operating loss carryforwards of approximately $4.1 million expire in 2036. The remaining U.S. federal net operating loss carryforward and the majority of the foreign loss carryforwards are available for carryforward indefinitely. The Company also had state net operating losses of approximately $0.6 million that are set to expire at varying periods between 2025 and 2040 if not utilized. As of December 31, 2020, the Company has a Texas Margin Tax Credit of $1.0 million and U.S. federal R&D credits of $0.1 million that may be utilized through 2026 and 2036, respectively. The Company has capital loss carryforwards of $0.2 million expiring in 2021 and 2022. The effective tax rate before income taxes varies from the current U.S. federal statutory income tax rate as follows: Years ended December 31, 2020 2019 Statutory rate 21.0 % 21.0 % State and local taxes 0.5 % 5.1 % Permanent differences (19.4 )% 26.6 % Tax credits 0.0 % 16.2 % Foreign operations (1.3 )% 8.2 % Uncertain tax positions (0.8 )% 1.6 % Valuation allowance (5.1 )% 21.0 % Other (0.5 )% (1.6 )% (5.6 )% 98.1 % A reconciliation of the beginning and ending amount of unrecognized tax benefits, including interest and penalties, is as follows: 2020 2019 Balance at January 1, $ 4,295 $ 4,115 (Decrease) increases in tax positions for current years (375 ) 455 Other (42 ) (149 ) Lapse in statute of limitations (235 ) (126 ) Settlements (97 ) — Balance at December 31, $ 3,546 $ 4,295 Of the amounts reflected in the above table at December 31, 2020, approximately $1.4 million would reduce the Company’s annual effective tax rate if recognized. This amount considers the indirect effects of offsetting tax positions in different jurisdictions. The Company records accrued interest and penalties related to income tax matters in the provision for income taxes in the accompanying consolidated statement of income. For the years ended December 31, 2020 and 2019, interest and penalties recognized on unrecognized tax benefits were $(287) and $134, respectively. The accrued balance as of December 31, 2020 and 2019 was $495 and $782, respectively. Included in the unrecognized tax benefits is a liability for the Romania income tax audit for tax years 2012-2016 and Italy for tax year 2016. Depending upon the final resolution of the audits, the uncertain tax position liabilities could be higher or lower than the amount recorded at December 31, 2020. We believe that it is reasonably possible that a decrease up to $0.7 million in unrecognized tax benefits within 12 months of the reporting date as a result of a lapse of the statute of limitations in various jurisdictions and for the resolution of the 2016 Italy audit. The Company files income tax returns in the United States, Italy, Romania, Argentina, and Chile as well as various state and local tax jurisdictions with varying statutes of limitations. With a few exceptions, the Company is no longer subject to examination by the tax authorities for U.S. federal or state for the years before 2017, or foreign examinations for years before 2012.

Compensation And Retirement Disclosure [Abstract]
Employee Benefits	Note 17. Employee Benefits U.S. Plan The Company sponsors a 401(k) plan. The plan is intended to cover all non-union United States based employees. The plan is open to employees 21 years of age and older. There is no minimum employment duration required before eligibility. The plan allows for monthly enrollment and contribution changes. The Company currently matches dollar for dollar participants’ contributions up to 3% of the participants’ gross income and a 50% match on the next 2% of gross income. There is no dollar limit regarding matched funds and the plan also calls for immediate vesting of the employer contribution component. The amount paid in matching contributions by the company for 2020 and 2019 were $336 and $388, respectively. Non-U.S. Plan Employees in Italy are entitled to Trattamento di Fine Rapporto (“TFR”), commonly referred to as an employee leaving indemnity, which represents deferred compensation for employees in the private sector. Under Italian law, an entity is obligated to accrue for TFR on an individual employee basis payable to each individual upon termination of employment (including both voluntary and involuntary dismissal). The annual accrual is approximately 7% of total pay, with no ceiling, and is revalued each year by applying a pre-established rate of return of 1.50%, plus 75% of the Consumer Price Index, and is recorded by a book reserve. TFR is an unfunded plan. The accrued employee severance indemnity must be transferred to the Fund for the payment of severance pay to employees in the private sector, managed by the INPS (the National Social Contributions Authority), on behalf of the State, on a special account opened at the State Treasury. In this case the workers continue to have as their sole interlocutor the employer, who will provide monthly payment of the amount due (together with the social contributions due to INPS). In this situation, the Company will pay the severance to the employees leaving and then those amounts will be compensated by the payments to be made in favor of INPS. The amount paid by the company for 2020 and 2019 was $521 and $146, respectively. The amount allocated to the Employee severance indemnity provision in 2020 and 2019 were $689 and $428, respectively.

As such, C&M purchases cranes and parts from Terex. The Company had a convertible note with a face amount of $7.5 million paid payable to Terex. This note was paid off in full in December 2020. PM is a manufacturer of cranes. PM sold cranes, parts, and accessories to Tadano during 2019 and 2020. During the quarter ended March 31, 2017, the Company was the majority owner of ASV and, therefore, ASV was not a related party during that period. In May 2017, the Company reduced is its ownership interest in ASV to 21.2% and in February 2018 further reduced its ownership to approximately 11%. As such, ASV became a related party beginning in the quarter ended June 30, 2017. The Company did not have any transactions with ASV during 2018. In September 2019, in connection with the sale of ASV to Yanmar American Corporation, the Company received cash merger consideration for its remaining 1,080,000 shares in ASV and ASV is no longer a related party at September 30, 2019.

Commitments And Contingencies Disclosure [Abstract]
Legal Proceedings and Other Contingencies	Note 21. Legal Proceedings and Other Contingencies The Company is involved in various legal proceedings, including product liability, employment related issues, and workers’ compensation matters which have arisen in the normal course of operations. The Company has product liability insurance with self-insurance retention that range from $50 to $500. The Company has been named as a defendant in several multi-defendant asbestos related product liability lawsuits. In certain instances, the Company is indemnified by a former owner of the product line in question. In the remaining cases the plaintiff has, to date, not been able to establish any exposure by the plaintiff to the Company’s products. The Company is uninsured with respect to these claims but believes that it will not incur any material liability with respect to these claims. Additionally, beginning on December 31, 2011 through December 31, 2019, the Company’s worker’s compensation insurance policy has per claim deductible of $250 and annual aggregates of $1,000 to $1,875 depending on the policy year. During 2020, the Company changed its insurance coverage and no longer has a deductible obligation. The Company is fully insured for any amount on any individual claim that exceeds the deductible and for any additional amounts of all claims once the aggregate is reached. The Company currently has several worker’s compensation claims related to injuries that occurred after December 31, 2011 and therefore are subject to a deductible. The Company does not believe that the contingencies associated with these worker compensation claims in aggregate will have a material adverse effect on the Company. On May 5, 2011, Company entered into two separate settlement agreements with two plaintiffs. As of December 31, 2020, the Company has a remaining obligation under the agreements to pay the plaintiffs $1,045 without interest in 11 annual installments of $95 on or before May 22 each year. The Company has recorded a liability for the net present value of the liability. The difference between the net present value and the total payment will be charged to interest expense over payment period. When it is probable that a loss has been incurred and possible to make a reasonable estimate of the Company’s liability with respect to such matters, a provision is recorded for the amount of such estimate to estimate the amount within the range that is most likely to occur. Certain cases are at a preliminary stage, and it is not possible to estimate the amount or timing of any cost to the Company. However, the Company does not believe that these contingencies, in the aggregate, will have a material adverse effect on the Company. It is reasonably possible that the “Estimated Reserve for Product Liability Claims” may change within the next 12 months. A change in estimate could occur if a case is settled for more or less than anticipated, or if additional information becomes known to the Company. SEC Investigation The Company has settled the previously disclosed SEC investigation regarding the Company’s restatement of prior financial statements.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Basis of Accounting Policy	The summary of significant accounting policies of Manitex International, Inc. is presented to assist in understanding the Company’s financial statements. The financial statements and notes are representations of the Company’s management who is responsible for their integrity and objectivity. These accounting policies conform to generally accepted accounting principles and have been consistently applied in the preparation of the financial statements.
Cash and Cash Equivalents	Cash and Cash Equivalents —For purposes of the statement of cash flows, the Company considers all short-term securities purchased with maturity dates of three months or less to be cash equivalents. The cash in the Company's U.S. banks (primarily CIBC) is not fully insured by the FDIC due to the statutory limit of $250.
Restricted Cash	Restricted Cash —Certain of the Company’s lending arrangements require the Company to post collateral or maintain minimum cash balances in escrow. These cash amounts are reported as current assets on the balance sheets based on when the cash will be contractually released. Total restricted cash was $240 and $217 at December 31, 2020 and 2019, respectively.
Revenue Recognition	Revenue Recognition —Revenue is recognized when obligations under the terms of the contract with our customer are satisfied; generally, this occurs with the transfer of control of our equipment, parts or installation services (typically completed within one day), which occurs at a point in time. Equipment can be redirected during the manufacturing phase such that over time revenue recognition is not appropriate. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Our contracts are non-cancellable and returns are only allowed in limited instances. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. The expected costs associated with our base warranties continue to be recognized as expense when the products are sold and do not constitute a separate performance obligation. For instances where equipment and installation services are sold together, the Company accounts for the equipment and installation services separately. The consideration (including any discounts) is allocated between the equipment and installation services based on their stand-alone selling prices. The stand-alone selling prices are determined based on the prices at which the Company separately sells the equipment . In some instances, the Company fulfills its obligations and bills the customer for the work performed but does not ship the goods until a later date. These arrangements are considered bill-and-hold transactions. In order to recognize revenue on the bill-and-hold transactions, the Company ensures the customer has requested the arrangement, the product is identified separately as belonging to the customer, the product is ready for shipment to the customer in its current form, and the Company does not have the ability to direct the product to a different customer. A portion of the transaction price is not allocated to the custodial services due to the immaterial value assigned to that performance obligation. Payment terms offered to customers are defined in contracts and purchase orders and do not include a significant financing component. At times, the Company may offer discounts which are considered variable consideration however, the Company applies the constraint guidance when determining the transaction price to be allocated to the performance obligations.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts —Accounts receivable are stated at the amounts the Company’s customers are invoiced and do not bear interest. The Company has adopted a policy consistent with U.S. GAAP for the periodic review of its accounts receivable to determine whether the establishment of an allowance for doubtful accounts is warranted based on the Company’s assessment of the collectability of the accounts. The Company established an allowance for bad debt of $2.6 million and $2.8 million at December 31, 2020 and 2019, respectively. The Company also has in some instances a security interest in its accounts receivable until payment is received.
Property, Equipment and Depreciation	Property, Equipment and Depreciation —Property and equipment are stated at cost or the fair market value at date of acquisition for property and equipment acquired in connection with the acquisition of a company. Depreciation of property and equipment is provided over the following useful lives: Asset Category Depreciable Buildings 12 –33 years Machinery and equipment 3 – 15 years Furniture and fixtures 3 – 10 years Leasehold improvements 5 Motor Vehicles 3 Computer software 3 Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred. Depreciation of property, and equipment is calculated using the straight-line method over the estimated useful lives of the assets. Depreciation expense for the years ended December 31, 2020 and 2019 was $2,011 and $2,071, respectively.
Other Intangible Assets	Other Intangible Assets —The Company capitalizes certain costs related to patent technology. Additionally, a substantial portion of the purchase price related to the Company’s acquisitions has been assigned to patents or unpatented technology, trade name, customer
Goodwill	Goodwill — Goodwill, representing the difference between the total purchase price and the fair value of assets (tangible and intangible) and liabilities at the date of acquisition, is reviewed for impairment annually, and more frequently as circumstances warrant, and written down only in the period in which the recorded value of such assets exceed their fair value. The Company does not amortize goodwill. Under “ASC 350”, entities are provided with the option of first performing a qualitative assessment on none, some, or all of its reporting units to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If after completing a qualitative analysis, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value a quantitative analysis is required. The Company evaluates its consolidated goodwill using the quantitative two step approach. The first step used to identify potential impairment involves comparing the reporting unit’s estimated fair value to its carrying value, including goodwill. During the first step testing, the Company evaluates goodwill for impairment using a business valuation method, which is calculated as of a measurement date by determining the present value of debt-free, after-tax projected future cash flows, discounted at the weighted average cost of capital of a hypothetical third-party buyer. The market approach was also considered in evaluating the potential for impairment by calculating fair value based on multiples of earnings before interest, taxes, depreciation and amortization (EBITDA) of comparable, publicly traded companies. The Company also observed implied EBITDA multiples from relatively recent merger and acquisition activity in the industry, which was used to test the reasonableness of the results. The second step of the process involves the calculation of an implied fair value of goodwill for each reporting unit for which step one indicated impairment. The implied fair value of goodwill is determined by measuring the excess of the estimated fair value of the reporting unit over the estimated fair values of the individual assets, liabilities and identifiable intangibles as if the reporting unit was being acquired in a business combination. If the implied fair value of goodwill exceeds the carrying value of goodwill assigned to the reporting unit, there is no impairment. If the carrying value of goodwill assigned to a reporting unit exceeds the implied fair value of the goodwill, an impairment charge is recorded for the excess. An impairment loss cannot exceed the carrying value of goodwill assigned to a reporting unit and the subsequent reversal of goodwill impairment losses is not permitted. The determination of fair value requires the Company to make significant estimates and assumptions. These estimates and assumptions primarily include, but are not limited to, revenue growth and operating earnings projections, discount rates, terminal growth rates, and required capital expenditure projections. In the event the Company determines that goodwill is impaired in the future the Company would need to recognize a non-cash impairment charge. The Company performed its annual impairment assessment as of March 31, 2020, prior to its October 1, 2020 annual measurement date. The valuation analysis was performed at March 31, 2020 due to the Company identifying a triggering event. Subsequently, a step 0 analysis was performed at December 31, 2020 indicating no impairment. In 2019,
Impairment of Long Lived Assets	Impairment of Long-Lived Assets — The Company’s policy is to assess the realizability of its long-lived assets, including intangible assets, and to evaluate such assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets (or group of assets) may not be recoverable. Impairment is determined to exist if the estimated future undiscounted cash flows are less than the carrying value. Future cash flow projections include assumptions for future sales levels, the impact of cost reduction programs, and the level of working capital needed to support each business. The amount of any impairment then recognized would be calculated as the difference between the estimated fair value and the carrying value of the asset. The Company recognized $6.7 million in impairment related to tradenames, goodwill and customer relationships for the year ended December 31, 2020. The Company recognized $1.5 million in impairment related to tradenames, goodwill and customer relationships for the year ended December 31, 2019.
Inventory	Inventory —Inventory consists of stock materials and equipment stated at the lower of cost (first in, first out) or net realizable value. All equipment classified as inventory is available for sale. The company records excess and obsolete inventory reserves. The estimated reserve is based upon specific identification and/or historical experience of excess or obsolete inventories. Selling, general and administrative expenses are expensed as incurred and are not capitalized as a component of inventory.
Accounting for Paycheck Protection Program	Accounting for Paycheck Protection Program —The Company has elected to account for the Paycheck Protection Program (PPP) loan as a government grant and as such, the loan was recorded as a deferred income liability on the balance sheet. The Company has applied for forgiveness of the loan. The offset will be recorded against the related expense on the income statement.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions —The financial statements of the Company’s non-U.S. subsidiaries are translated using the current exchange rate for assets and liabilities and the weighted-average exchange rate for the year for income and expense items. Resulting translation adjustments are recorded to accumulated other comprehensive income (OCI) as a component of shareholders’ equity The Company converts receivables and payables denominated in other than the Company’s functional currency at the exchange rate as of the balance sheet date. The resulting transaction exchange gains or losses, except for certain transaction gains or loss related to intercompany receivable and payables, are included in other income and expense. Transaction gains and losses related to intercompany receivables and payables not anticipated to be settled in the foreseeable future are excluded from the determination of net income and are recorded as a translation adjustment (with consideration to the tax effect) to accumulated other comprehensive income (OCI) as a component of shareholders’ equity.
Derivatives-Forward Currency Exchange Contracts	Derivatives—Forward Currency Exchange Contracts —When the Company enters into forward currency exchange contracts it does so such that the exchange gains and losses on the assets and liabilities that are being hedged, which are denominated in a currency other than the reporting units’ functional currency, would be offset by the changes in the market value of the forward currency exchange contracts it holds. The forward currency exchange contracts that the Company has to offset existing assets and liabilities denominated in other than the reporting units’ functional currency have been determined not to be considered a hedge. The Company records the forward currency exchange contracts at its market value with any associated gain or loss being recorded in current earnings. Both realized and unrealized gains and losses related to forward currency contracts are included in current earnings and are reflected in the Consolidated Statements of Operations in the other income expense section on the line titled foreign currency transaction loss.
Research and Development Expenses	Research and Development Expenses — The Company expenses research and development costs, as incurred. For the periods ended December 31, 2020 and 2019 expenses were $3,227 and $2,714, respectively.
Advertising	Advertising —Advertising costs are expensed as incurred and were $ and $ 965 for the years ended December 31, 20 20 and 201 9 , respectively.
Retirement Benefit Costs and Termination Benefits	Retirement Benefit Costs and Termination Benefits —Payments to defined contribution retirement benefit plans are recognized as an expense when employees have rendered service entitling them to the contributions. Employees in Italy are entitled to Trattamento di Fine Rapporto (“TFR”), commonly referred to as an employee leaving indemnity, which represents deferred compensation for employees in the private sector. Under Italian law, an entity is obligated to accrue for TFR on an individual employee basis payable to each individual upon termination of employment (including both voluntary and involuntary dismissal). The expense is recognized in the personnel costs (SG&A or COGS) in the Consolidated Statements of Operations and the accrual is recorded in other long-term liability in the Consolidated Balance Sheets.
Litigation Claims	Litigation Claims —In determining whether liabilities should be recorded for pending litigation claims, the Company must assess the allegations and the likelihood that it will successfully defend itself. When the Company believes it is probable that it will not prevail in a particular matter, it will then record an estimate of the amount of liability based, in part, on advice of legal counsel
Shipping and Handling	Shipping and Handling —The Company records the amount of shipping and handling costs billed to customers as revenue. The cost incurred for shipping and handling is included in the cost of sales.
Adoption of Highly Inflationary Accounting	Adoption of Highly Inflationary Accounting in Argentina — GAAP guidance requires the use of highly inflationary accounting for countries whose cumulative three-year inflation exceeds 100 percent. In the second quarter of 2018, published inflation indices indicated that the three-year cumulative inflation in Argentina exceeded 100 percent, and as of July 1, 2018, we elected to adopt highly inflationary accounting for our subsidiary in Argentina (“PM Argentina”). Under highly inflationary accounting, PM Argentina’s functional currency became the Euro (its parent company’s reporting currency), and its income statement and balance sheet have been measured in Euros using both current and historical rates of exchange. The effect of changes in exchange rates on peso-denominated monetary assets and liabilities has been reflected in earnings in other (income) and expense, net and was not material. As of December 31, 2020, PM Argentina had a small net peso monetary position. Net sales of PM Argentina were less than 5 percent of our consolidated net sales for the years ended December 31, 2020 and 2019, respectively.
Income Taxes	Income Taxes — On March 27, 2020, the “Coronavirus Aid, Relief and Economic Security (CARES) Act” was enacted. The CARES Act, among other things, includes provisions relating to net operating loss carrybacks, alternative minimum tax credit refunds, a modification to the net interest deduction limitations and a technical correction to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company’s consolidated financial statements for the year ended December 31, 2020. The Company accounts for income taxes under the provisions of ASC 740 “Income Taxes,” which requires recognition of income taxes based on amounts payable with respect to the current year and the effects of deferred taxes for the expected future tax consequences of events that have been included in the Company’s financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial accounting and tax basis of assets and liabilities, as well as for operating losses and tax credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are recorded to reduce deferred tax assets when it is more-likely-than-not a tax benefit will not be realized. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income prior to the expiration of any net operating loss carryforwards. See Note 15, Income Taxes, for further details. The Jobs Act also establishes Global Intangible Low-Taxed Income (“GILTI”) provisions that impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The Company has elected to recognize GILTI as a period cost as incurred, therefore there are no deferred taxes recognized for basis differences that are expected to impact the amount of the GILTI inclusion upon reversal. ASC 740 also prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, as well as guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company records interest and penalties related to income tax matters in the provision for income taxes.
Accrued Warranties	Accrued Warranties —Warranty costs are accrued at the time revenue is recognized. The Company’s products are typically sold with a warranty covering defects that arise during a fixed period of time. The specific warranty offered is a function of customer expectations and competitive forces. A liability for estimated warranty claims is accrued at the time of sale. The liability is established using historical warranty claim experience. The current provision may be adjusted to take into account unusual or non-recurring events in the past or anticipated changes in future warranty claims. Adjustments to the initial warranty accrual are recorded if actual claim experience indicates that adjustments are necessary. As of December 31, 2020 and 2019, accrued warranties were $1,292 and $1,604, respectively.
Debt Issuance Costs	Debt Issuance Costs —Debt issuance costs incurred in securing the Company’s financing arrangements are capitalized and amortized over the term of the associated debt. Deferred financing costs associated with long-term debt are presented in the balance sheet as direct deduction from the carrying amount of that debt liability, consistent with debt discount. Deferred financing costs associated with revolving lines of credit are included with other long-term assets on the Company’s Consolidated Balance Sheets.
Sale and Leaseback	Sale and Leaseback —In accordance with ASC 842-10 Sales-Leaseback Transactions, the Company has recorded a deferred gain in relationship to the sale and leaseback of one of the Company’s operating facilities and on certain equipment. As such, the gains have been deferred and are being amortized on a straight- line basis over the life of the leases.
Computation of EPS	Computation of EPS —Basic Earnings per Share (“EPS”) was computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. The number of shares related to options, warrants, restricted stock, convertible debt and similar instruments included in diluted EPS (“EPS”) is based on the “Treasury Stock Method” prescribed in ASC 260-10, Earnings per Share. This method assumes the theoretical repurchase of shares using proceeds of the respective stock option or warrant exercised, and for restricted stock, the amount of compensation cost attributed to future services which has not yet been recognized, and the amount of current and deferred tax benefit, if any, that would be credited to additional paid in capital upon the vesting of the restricted stock, at a price equal to the issuer’s average stock price during the related earnings period. Accordingly, the number of shares includable in the calculation of EPS in respect of the stock options, warrants, restricted stock, convertible debt, and similar instruments is dependent on this average stock price and will increase as the average stock price increases.
Stock Based Compensation	Stock Based Compensation —In accordance with ASC 718 Compensation-Stock Compensation, share-based payments to employees, including grants of restricted stock units, are measured at fair value as of the date of grant and are expensed in the Consolidated Statements of Operation over the service period (generally the vesting period).
Comprehensive Income	Comprehensive Income —Comprehensive income includes, in addition to net earnings, other items that are reported as direct adjustments to shareholder’s equity. Currently, the comprehensive income adjustment required for the Company is a foreign currency translation adjustment, the result of consolidating its foreign subsidiary.
Business Combinations	Business Combinations —The Company accounts for acquisitions in accordance with guidance found in ASC 805, Business Combinations. The guidance requires consideration given, including contingent consideration, assets acquired, and liabilities assumed to be valued at their fair market values at the acquisition date. The guidance further provides that: (1) in-process research and development will be recorded at fair value as an indefinite-lived intangible asset; (2) acquisition costs will generally be expensed as incurred, (3) restructuring costs associated with a business combination will generally be expensed subsequent to the acquisition date; and (4) changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally will affect income tax expense. The Company records any excess of purchase price over fair value of assets acquired, including identifiable intangibles and liabilities assumed be recognized as goodwill.
Reclassifications	Reclassification —A reclassification to properly reflect a decrease in long-term liabilities of discontinued operations of $0.4 million, an increase in deferred tax liability of $0.3 million, and a decrease in deferred tax asset of $0.1 million was recorded in the fourth quarter of 2020 for the year ended December 31, 2019.
