Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	3. Revenue & Receivables Revenue Recognition: Performance obligations The Company has contracts with customers for standard products and custom engineered products and determines when and how to recognize revenue for each performance obligation based on the nature and type of contract. Revenue from contracts with customers for standard products is recognized when legal title and significant risk and rewards has transferred to the customer, which is generally at the time of shipment. This is the point in time when control is deemed to transfer to the customer. The Company sells standard products to customers utilizing purchase orders. Payment terms for these types of contracts generally require payment within 30-60 days. Each standard product is deemed to be a single performance obligation and the amount of revenue recognized is based on the negotiated price. The transaction price for standard products is based on the price reflected in each purchase order. Sales incentives are offered to customers who purchase standard products and include offers such as volume-based discounts, rebates for priority customers, and discounts for early cash payments. These sales incentives are accounted for as variable consideration included in the transaction price. Accordingly, the Company reduces revenue for these incentives in the period which the sale occurs and is based on the most likely amount method for estimating the amount of consideration the Company expects to receive. These sales incentive estimates are updated each reporting period as additional information becomes available. The Company also sells custom engineered products and services which are contracts that are typically completed within one quarter but can extend beyond one year in duration. For custom engineered products, the transaction price is based upon the price stated in the contract. Variable consideration has not been identified as a significant component of transaction price for custom engineered products and services. The Company generally recognizes revenue for custom engineered products upon satisfaction of its performance obligation under the contract which typically coincides with project completion which is when the products and services are controlled by the customer. Control is typically achieved at the later of when legal title and significant risk and rewards have transferred to the customer or the customer has accepted the asset. These contracts often require either up front or installment payments. These types of contracts are generally accounted for as one performance obligation as the products and services are not separately identifiable. The promised services (such as inspection, commissioning, and installation) are essential in order for the delivered product to operate as intended on the customer’s site and the services are therefore highly interrelated with product functionality. For most custom engineered products contracts, the Company determined that while there is no alternative use for the custom engineered products, the Company does not have an enforceable right to payment (which must include a reasonable profit margin) for performance completed to date in order to meet the over time revenue recognition criteria. Therefore, revenue is recognized at a point in time (when the contract is complete). For custom engineered products contracts that contain an enforceable right to payment (including reasonable profit margin) the Company satisfies the performance obligation over time and recognizes revenue based on the extent of progress towards completion of the performance obligation. The cost-to-cost measure of progress is an appropriate measure of progress toward satisfaction of performance obligations as this measure most accurately depicts the progress of work performed and transfer of control to the customers. Under the cost-to-cost measure of progress, the extent of progress toward completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recognized proportionally as costs are incurred. Sales and other taxes collected with revenue are excluded from revenue, consistent with the previous revenue standard. Shipping and handling costs incurred prior to shipment are considered activities required to fulfill the Company’s promise to transfer goods, and do not qualify as a separate performance obligation. Additionally, the Company offers standard warranties which are typically 12 months in duration for standard products and 24 to 36 months for custom engineered products. These types of warranties are included in the purchase price of the product and are deemed to be assurance-type warranties which are not accounted for as a separate performance obligation. Other performance obligations included in a contract (such as drawings, owner’s manuals, and training services) are immaterial in the context of the contract and are not recognized as a separate performance obligation. For additional information on the Company’s revenue recognition policy refer to the consolidated financial statements included in the 2020 10-K. Reconciliation of contract balances The Company records a contract liability when cash is received prior to recording revenue. Some standard contracts require a down payment while most custom engineered contracts require installment payments. Installment payments for the custom engineered contracts typically require a portion due at inception while the remaining payments are due upon completion of certain performance milestones. For both types of contracts, these contract liabilities, referred to as customer advances, are recorded at the time payment is received and are included in Accrued liabilities on the Condensed Consolidated Balance Sheets. When the related performance obligation is satisfied and revenue is recognized, the contract liability is released into income. The following table illustrates the balance and related activity for customer advances in the nine months ending December 31, 2020 and December 31, 2019 (in thousands): Customer advances (contract liabilities) December 31, 2020 December 31, 2019 March 31, beginning balance $ 10,796 $ 11,501 Additional customer advances received 28,411 26,745 Revenue recognized from customer advances (24,636) (25,773) Other (1) 1,187 27 December 31, ending balance $ 15,758 $ 12,500 (1) Other includes the impact of foreign currency translation During the nine months ended December 31, 2020, revenue was recognized prior to the right to invoice the customer which resulted in a contract asset balance in the amount of $4,860,000 and $2,361,000 as of December 31, 2020 and March 31, 2020, respectively. Contract assets are included in Prepaid expenses and other assets on the Condensed Consolidated Balance Sheets. Remaining Performance Obligations As of December 31, 2020, the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied (or partially unsatisfied) was approximately $8,193,000. We expect to recognize approximately 90% of these sales over the next twelve months. Disaggregated revenue In accordance with ASC 606, the Company is required to disaggregate revenue into categories that depict how economic factors affect the nature, amount, timing and uncertainty of revenue and cash flows. The following table illustrates the disaggregation of revenue by product grouping for the three and nine months ending December 31, 2020 and December 31, 2019 (in thousands): Three Months Ended Nine Months Ended Net Sales by Product Grouping December 31, 2020 December 31, 2019 December 31, 2020 December 31, 2019 Industrial Products $ 71,090 $ 84,067 $ 192,127 $ 267,459 Crane Solutions 75,970 92,134 $ 216,602 $ 287,374 Engineered Products 19,454 23,134 $ 54,611 $ 64,795 All other 33 20 $ 67 $ 48 Total $ 166,547 $ 199,355 $ 463,407 $ 619,676 Industrial products include: manual chain hoists, electrical chain hoists, rigging/ clamps, industrial winches, hooks, shackles, and other forged attachments. Crane solutions products include: wire rope hoists, drives and controls, crane kits and components, and workstations. Engineered products include: linear and mechanical actuators, lifting tables, rail projects, and actuations systems. The All other product grouping includes miscellaneous revenue. Practical expedients Incremental costs to obtain a contract incurred by the Company primarily relate to sales commissions for contracts with a duration of one year or less. Therefore, these costs are expensed as incurred and are recorded in Selling expenses on the Condensed Consolidated Statements of Operations. Unsatisfied performance obligations for contracts with an expected length of one year or less are not disclosed. Further, revenue from contracts with customers do not include a significant financing component as payment is generally expected within one year from when the performance obligation is controlled by the customer. Accounts Receivable: In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). The standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. The Company adopted this standard effective April 1, 2020 under the modified retrospective method whereas comparative period information is not restated. The adoption of this standard did not have a significant impact on the Company’s consolidated financial statements, therefore no cumulative effect or catch up adjustment to the opening balance of retained earnings was recorded. Additionally, the Company identified and implemented appropriate changes to it's allowance for doubtful accounts policy and internal controls to support reporting and disclosures. Under ASU 2016-13, the Company is required to remeasure expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable forecasts. In addition to these factors, the Company establishes an allowance for doubtful accounts based upon the credit risk of specific customers, historical trends, and other factors. Accounts receivable are charged against the allowance for doubtful accounts once all collection efforts have been exhausted. Due to the short-term nature of such accounts receivable, the estimated amount of accounts receivable that may not be collected is based on aging of the accounts receivable balances. In response to COVID-19, the Company continues to monitor the impact that COVID-19 is having on our customers and their outstanding receivable balances and is taking preventative measures, such as reducing credit limits and increasing bad debt expense, as necessary. The following table illustrates the balance and related activity for the allowance for doubtful accounts that is deducted from accounts receivable to present the net amount expected to be collected in the nine months ending December 31, 2020 (in thousands): Allowance for doubtful accounts December 31, 2020 March 31, beginning balance $ 5,056 Bad debt expense 2,512 Less uncollectible accounts written off, net of recoveries (1,405) Other (1) 284 December 31, ending balance $ 6,447

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements FASB ASC Topic 820 “Fair Value Measurements and Disclosures” establishes the standards for reporting financial assets and liabilities and nonfinancial assets and liabilities that are recognized or disclosed at fair value on a recurring basis (at least annually). Under these standards, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the "exit price") in an orderly transaction between market participants at the measurement date. ASC 820-10-35-37 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the valuation techniques that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is separated into three levels based on the reliability of inputs as follows: Level 1 - Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Level 2 - Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly, involving some degree of judgment. Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The availability of observable inputs can vary and is affected by a wide variety of factors, including the type of asset/liability, whether the asset/liability is established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, assumptions are required to reflect those that market participants would use in pricing the asset or liability at the measurement date. The Company uses quoted market prices when valuing its marketable securities and, consequently, the fair value is based on Level 1 inputs. These marketable securities consist of equity and fixed income securities. The Company's terminated pension assets consist of money market funds which are valued using quoted market prices, and consequently, the fair value is based on Level 1 inputs. Refer to Note 10 for more information regarding the Company's terminated pension. The Company primarily uses readily observable market data in conjunction with internally developed discounted cash flow valuation models when valuing its derivative portfolio and, consequently, the fair value of the Company’s derivatives is based on Level 2 inputs. The carrying amount of the Company's pension-related annuity contract is recorded at net asset value of the contract and, consequently, its fair value is based on Level 2 inputs and is included in Other assets on the Condensed Consolidated Balance Sheets. The carrying value of the Company’s Term Loan approximates fair value based on current market interest rates for debt instruments of similar credit standing and, consequently, their fair values are based on Level 2 inputs. The following table provides information regarding financial assets and liabilities measured or disclosed at fair value (in thousands): Fair value measurements at reporting date using December 31, Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs Description 2020 (Level 1) (Level 2) (Level 3) Assets/(Liabilities) measured at fair value: Marketable securities $ 7,925 $ 7,925 $ — $ — Annuity contract 2,096 — 2,096 — Terminated pension assets 3,902 3,902 Derivative Assets (Liabilities): Foreign exchange contracts 11 — 11 — Interest rate swap liability (2,512) — (2,512) — Cross currency swap liability (21,398) — (21,398) — Disclosed at fair value: Term loan $ (256,653) $ — $ (256,653) $ — Fair value measurements at reporting date using March 31, Quoted prices in active markets for identical assets Significant other observable inputs Significant unobservable inputs Description 2020 (Level 1) (Level 2) (Level 3) Assets/(Liabilities) measured at fair value: Marketable securities $ 7,322 $ 7,322 $ — $ — Annuity contract 2,059 — 2,059 — Derivative assets (liabilities): Foreign exchange contracts 285 — 285 — Interest rate swap asset (3,296) — (3,296) — Cross currency swap liability (5,254) — (5,254) — Cross currency swap asset 1,750 — 1,750 — Disclosed at fair value: Term loan $ (239,899) $ — $ (239,899) $ — The Company does not have any non-financial assets and liabilities that are recognized at fair value on a recurring basis. At December 31, 2020, the Term loan has been recorded at carrying value which approximates fair value. Market gains, interest, and dividend income on marketable securities are recorded in Investment (income) loss on the Condensed Consolidated Statements of Operations. Changes in the fair value of derivatives are recorded in foreign currency exchange (gain) loss or other comprehensive income (loss), to the extent that the derivative qualifies as a hedge under the provisions of ASC Topic 815. Interest and dividend income on marketable securities are measured based upon amounts earned on their respective declaration dates.

Accordingly, interim LIFO calculations must necessarily be based on management's estimates of expected year-end inventory levels and costs. Because these are subject to many factors beyond management's control, estimated interim results are subject to change in the final year-end LIFO inventory valuation.

Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure	6. Marketable Securities and Other Investments In accordance with ASU 2016-01 “Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” adopted by the Company on April 1, 2018, all equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) are measured at fair value through earnings. The Company's marketable securities are recorded at their fair value, with unrealized changes in market value realized within Investment (income) loss on the Condensed Consolidated Statements of Operations. The impact on earnings for unrealized gains and losses was a gain of $195,000 and $67,000 in the three months ended December 31, 2020 and December 31, 2019, respectively. The impact on earnings for unrealized gains and losses was a gain of $682,000 and $232,000 in the nine months ended December 31, 2020 and December 31, 2019, respectively. Consistent with prior periods, the estimated fair value is based on quoted market prices at the balance sheet dates. The cost of securities sold is based on the specific identification method. Interest and dividend income are included in Investment (income) loss in the Condensed Consolidated Statements of Operations. Marketable securities are carried as long-term assets since they are held for the settlement of the Company’s general and product liability insurance claims filed through CM Insurance Company, Inc. ("CMIC"), a wholly owned captive insurance subsidiary. The marketable securities are not available for general working capital purposes. Net realized gains related to sales of marketable securities were not material in the three and nine months ended December 31, 2020 and December 31, 2019, respectively.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	7. Goodwill and Intangible Assets Goodwill and indefinite lived trademarks are not amortized but are tested for impairment at least annually, in accordance with the provisions of ASC Topic 350-20-35-1. Goodwill impairment is deemed to exist if the net book value of a reporting unit exceeds its estimated fair value. The fair value of a reporting unit is determined using a discounted cash flow methodology. The Company’s reporting units are determined based upon whether discrete financial information is available and reviewed regularly, whether those units constitute a business, and the extent of economic similarities between those reporting units for purposes of aggregation. The Company’s reporting units identified under ASC Topic 350-20-35-33 are at the component level, or one level below the operating segment level as defined under ASC Topic 280-10-50-10 “Segment Reporting - Disclosure.” The Company has two reporting units as of December 31, 2020 and March 31, 2020. The Duff-Norton reporting unit (which designs, manufactures and sources mechanical and electromechanical actuators and rotary unions) had goodwill of $9,710,000 and $9,593,000 at December 31, 2020 and March 31, 2020 and the Rest of Products reporting unit (representing the hoist, chain, forgings, digital power, motion control, manufacturing, and distribution businesses) had goodwill of $329,285,000 and $310,086,000 at December 31, 2020 and March 31, 2020, respectively. Refer to the 2020 10-K for information regarding our annual goodwill and indefinite lived trademark impairment evaluation. Future impairment indicators, such as declines in forecasted cash flows, may cause impairment charges. Impairment charges could be based on such factors as the Company’s stock price, forecasted cash flows, assumptions used, control premiums or other variables. There were no such indicators during the quarter ended December 31, 2020.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	8. Derivative Instruments The Company uses derivative instruments to manage selected foreign currency and interest rate exposures. The Company does not use derivative instruments for speculative trading purposes. All derivative instruments must be recorded on the balance sheet at fair value. For derivatives designated as cash flow hedges, changes in the fair value of the derivative is recorded as accumulated other comprehensive loss, or “AOCL,” and is reclassified to earnings when the underlying transaction has an impact on earnings. For foreign currency derivatives not designated as cash flow hedges, all changes in market value are recorded as a foreign currency exchange loss (gain) in the Company’s Consolidated Statements of Operations. The cash flow effects of derivatives are reported within net cash (used for) provided by operating activities on the Condensed Consolidated Statements of Cash Flows. The Company is exposed to credit losses in the event of non-performance by the counterparties on its financial instruments. The counterparties have investment grade credit ratings. The Company anticipates that these counterparties will be able to fully satisfy their obligations under the contracts. The Company has derivative contracts with three counterparties as of December 31, 2020. The Company's agreements with its counterparties contain provisions pursuant to which the Company could be declared in default of its derivative obligations. As of December 31, 2020, the Company had not posted any collateral related to these agreements. If the Company had breached any of these provisions as of December 31, 2020, it could have been required to settle its obligations under these agreements at amounts which approximate the December 31, 2020 fair values reflected in the table below. During the nine months ended December 31, 2020, the Company was not in default of any of its derivative obligations. As of December 31, 2020, the Company had no derivatives designated as net investments or fair value hedges in accordance with ASC Topic 815, “Derivatives and Hedging.” The Company has a cross currency swap agreement that is designated as a cash flow hedge to hedge changes in the value of an intercompany loan to a foreign subsidiary due to changes in foreign exchange rates. This intercompany loan is related to the acquisition of STAHL. The notional amount of this derivative is $153,820,000, and this contract matures on January 31, 2022. From its December 31, 2020 balance of AOCL, the Company expects to reclassify approximately $684,000 out of AOCL, and into foreign currency exchange loss (gain), during the next 12 months based on the contractual payments due under this intercompany loan. The Company has foreign currency forward agreements that are designated as cash flow hedges to hedge a portion of forecasted inventory purchases denominated in foreign currencies. The notional amount of those derivatives is $294,000, and all contracts mature by March 31, 2021. From its December 31, 2020 balance of AOCL, the Company expects to reclassify approximately $10,000 out of AOCL during the next 12 months based on the expected sales of the goods purchased. The Company's policy is to maintain a capital structure that is comprised of 50-70% of fixed rate long term debt and 30-50% of variable rate long term debt. The Company has two interest rate swap agreements in which the Company receives interest at a variable rate and pays interest at a fixed rate. These interest rate swap agreements are designated as cash flow hedges to hedge changes in interest expense due to changes in the variable interest rate of the senior secured term loan. The amortizing interest rate swaps mature on December 31, 2023 and have a total notional amount of $134,888,000 as of December 31, 2020. The changes in fair values of the interest rate swaps is reported in AOCL and will be reclassified to interest expense over the life of the swap agreements. From its December 31, 2020 balance of AOCL, the Company expects to reclassify approximately $984,000 out of AOCL, and into interest expense, during the next 12 months.

Debt Disclosure [Abstract]
Debt	9. Debt On January 31, 2017 the Company entered into a Credit Agreement ("Credit Agreement") and $545,000,000 of new debt facilities ("Facilities") in connection with the STAHL acquisition. The Facilities consist of a Revolving Facility ("Revolver") in the amount of $100,000,000 and a $445,000,000 1st Lien Term Loan ("Term Loan"). The Term Loan has a seven-year term maturing in 2024. On August 26, 2020, the Company entered into a Second Amendment to the Credit Agreement (as amended by the First Amendment, dated as of February 26, 2018). The Second Amendment extends the $100,000,000 secured Revolver which was originally set to expire on January 31, 2022 to August 25, 2023. During the three months ended June 30, 2020, the Company drew $25,000,000 from the Revolver for liquidity and working capital purposes. The borrowings on the Revolver triggered the debt covenant provision which requires the Total Leverage Ratio not to exceed 3.00:1.00 as of December 31, 2019 and thereafter. The Company has been in compliance with this provision. During the three months ended December 31, 2020, the Company repaid the $25,000,000 from the Revolver and associated interest. As a result, this provision no longer applies, but if it had, the Company would have been in compliance with this provision of the Credit Agreement. The outstanding principal balance of the Term Loan was $256,013,000 as of December 31, 2020. The Company repaid $1,113,000 and $3,338,000 of required principal payments on the Term Loan during the three and nine months ended December 31, 2020. The Company is obligated to make $4,450,000 of principal payments over the next 12 months. In response to COVID-19 the Company is seeking to take all appropriate measures to protect the cash flow and liquidity of the Company. As such, only the required principal amount has been recorded within the current portion of long-term debt on the Company's Condensed Consolidated Balance Sheet with the remaining balance recorded as long-term debt. There were no outstanding borrowings and $17,005,000 in outstanding letters of credit issued against the Revolver as of December 31, 2020. The outstanding letters of credit as of December 31, 2020 consisted of $281,000 in commercial letters of credit and $16,724,000 of standby letters of credit. The gross balance of deferred financing costs on the Term Loan was $14,690,000 as of December 31, 2020 and March 31, 2020. The accumulated amortization balances were $8,219,000 and $6,645,000 as of December 31, 2020 and March 31, 2020, respectively. The gross balance of deferred financing costs associated with the Revolver is $3,615,000 as of December 31, 2020 and $2,789,000 as of March 31, 2020, which is included in other assets on the Condensed Consolidated Balance Sheet. The accumulated amortization balances were $2,179,000 and $1,766,000 as of December 31, 2020 and March 31, 2020, respectively. Unsecured and uncommitted lines of credit are available to meet short-term working capital needs for certain of our subsidiaries operating outside of the U.S. The lines of credit are available on an offering basis, meaning that transactions under the line of credit will be on such terms and conditions, including interest rate, maturity, representations, covenants and events of default, as mutually agreed between our subsidiaries and the local bank at the time of each specific transaction. As of December 31, 2020, unsecured credit lines totaled approximately $2,687,000, of which $0 was drawn. In addition, unsecured lines of $16,562,000 were available for bank guarantees issued in the normal course of business of which $13,757,000 was utilized.

The lump sum payments were paid during the three months ending June 30, 2020 and resulted in a settlement charge of $2,722,000 which was recorded in Other (income) expense, net on the Condensed Consolidated Statements of Operations. During the quarter ended September 30, 2020, the Company purchased annuity contracts to settle the remaining liabilities of the terminated plan. The total settlement charge was $18,933,000 which was recorded in Other (income) expense, net on the Condensed Consolidated Statements of Operations during the nine months ending December 31, 2020. The settlement gain of $113,000 during the three months ended December 31, 2020 is the result of a true up of estimates initially recorded. The remaining surplus of the terminated plan of $3,902,000 will be used, as prescribed in the applicable regulations, to fund obligations associated with the Company's U.S. defined contribution plans. The Company currently plans to contribute approximately $5,330,000 to its pension plans in fiscal 2021.

The shares as of the nine months ended December 31, 2020 were antidilutive as a result of the Company's net loss. Stock options, restricted stock units, and performance shares with respect to 234,000 common shares for the three and nine months ended December 31, 2019 were not included in the computation of diluted loss per share because they were antidilutive. For the three and nine months ended December 31, 2020, 105,000 contingently issuable common shares were excluded because a performance condition had not yet been met. The Company grants share based compensation to eligible participants under the 2016 Long Term Incentive Plan, as Amended and Restated in June 2019 ("2016 LTIP"). The total number of shares of common stock with respect to which awards may be granted under the 2016 LTIP were increased by 2,500,000 as a result of the June 2019 amendment. Shares not previously authorized for issuance under any of the prior stock plans and any shares not issued or subject to outstanding awards under the prior stock plans are still available for issuance. During the first nine months of fiscal 2021, there were 90,000 shares of stock issued upon the exercising of stock options related to the Company’s stock option plans. During the fiscal year ended March 31, 2020, 106,792 shares of restricted stock units vested and were issued. On January 18, 2021 the Company's Board of Directors declared a dividend of $0.06 per common share. The dividend will be paid on February 16, 2021 to shareholders of record on February 5, 2021. The dividend payment is expected to be approximately $1,440,000.

Commitments and Contingencies Disclosure [Abstract]
Legal Matters and Contingencies	12. Loss Contingencies From time to time, the Company is named a defendant in legal actions arising out of the normal course of business. The Company is not a party to any pending legal proceeding other than ordinary, routine litigation incidental to our business. The Company does not believe that any of our pending litigation will have a material impact on its business. Accrued general and product liability costs are actuarially estimated reserves based on amounts determined from loss reports, individual cases filed with the Company, and an amount for losses incurred but not reported. The aggregate amounts of reserves were $21,422,000 (gross of estimated insurance recoveries of $8,391,000 recorded in Other assets on the Condensed Consolidated Balance Sheet) as of December 31, 2020, of which $17,922,000 is included in Other non current liabilities and $3,500,000 in Accrued liabilities. The liability for accrued general and product liability costs are funded by investments in marketable securities (see Note 6). The following table provides a reconciliation of the beginning and ending balances for accrued general and product liability: December 31, 2020 March 31, 2020 Accrued general and product liability, beginning of period $ 11,944 $ 12,686 Estimated insurance recoveries 8,391 — Add provision for claims 3,749 3,233 Deduct payments for claims (2,662) (3,975) Accrued general and product liability, end of period $ 21,422 $ 11,944 Estimated insurance recoveries (8,391) — Net accrued general and product liability, end of period $ 13,031 $ 11,944 The per occurrence limits on the self-insurance for general and product liability coverage to the Columbus McKinnon through its wholly-owned captive insurance company were $2,000,000 from inception through fiscal 2003 and $3,000,000 for fiscal 2004 and thereafter. In addition to the per occurrence limits, the Company’s coverage is also subject to an annual aggregate limit, applicable to losses only. These limits range from $2,000,000 to $6,000,000 for each policy year from inception through fiscal 2021. Along with other manufacturing companies, the Company is subject to various federal, state and local laws relating to the protection of the environment. To address the requirements of such laws, the Company has adopted a corporate environmental protection policy which provides that all of its owned or leased facilities shall, and all of its employees have the duty to, comply with all applicable environmental regulatory standards, and the Company utilizes an environmental auditing program for its facilities to ensure compliance with such regulatory standards. The Company has also established managerial responsibilities and internal communication channels for dealing with environmental compliance issues that may arise in the course of its business. Because of the complexity and changing nature of environmental regulatory standards, it is possible that situations will arise from time to time requiring the Company to incur expenditures in order to ensure environmental regulatory compliance. However, the Company is not aware of any environmental condition or any operation at any of its facilities, either individually or in the aggregate, which would cause expenditures having a material adverse effect on its results of operations, financial condition or cash flows and, accordingly, has not budgeted any material capital expenditures for environmental compliance for fiscal 2021. We have entered a voluntary environmental cleanup program in certain states where we operate and believe that our current reserves are sufficient to remediate these locations. For all of the currently known environmental matters, we have accrued as of December 31, 2020 a total of $899,000 which, in our opinion, is sufficient to deal with such matters. The Company is not aware of any environmental condition or any operation at any of its facilities, either individually or in the aggregate, which would cause expenditures to have a material adverse effect on its results of operations, financial condition or cash flows and, accordingly, has not budgeted any material capital expenditures for environmental compliance for fiscal 2021. Like many industrial manufacturers, the Company is involved in asbestos-related litigation. In continually evaluating costs relating to its estimated asbestos-related liability, the Company reviews, among other things, the incidence of past and recent claims, the historical case dismissal rate, the mix of the claimed illnesses and occupations of the plaintiffs, its recent and historical resolution of the cases, the number of cases pending against it, the status and results of broad-based settlement discussions, and the number of years such activity might continue. Based on this review, the Company has estimated its share of liability to defend and resolve probable asbestos-related personal injury claims. This estimate is highly uncertain due to the limitations of the available data and the difficulty of forecasting with any certainty the numerous variables that can affect the range of the liability. The Company will continue to study the variables in light of additional information in order to identify trends that may become evident and to assess their impact on the range of liability that is probable and estimable. Based on actuarial information, the Company has estimated its net asbestos-related aggregate liability including related legal costs to range between $5,400,000 and $9,700,000 using actuarial parameters of continued claims for a period of 37 years from December 31, 2020. The Company's estimation of its net asbestos-related aggregate liability that is probable and estimable, in accordance with U.S. generally accepted accounting principles approximates $7,150,000, which has been reflected as a liability in the Condensed Consolidated Balance Sheet as of December 31, 2020. The recorded liability does not consider the impact of any potential favorable federal legislation. This liability will fluctuate based on the uncertainty in the number of future claims that will be filed and the cost to resolve those claims, which may be influenced by a number of factors, including the outcome of the ongoing broad-based settlement negotiations, defensive strategies, and the cost to resolve claims outside the broad-based settlement program. Of this amount, management expects to incur asbestos liability payments of approximately $2,000,000 over the next 12 months. Because payment of the liability is likely to extend over many years, management believes that the potential additional costs for claims will not have a material effect on the financial condition of the Company or its liquidity, although the effect of any future liabilities recorded could be material to earnings in a future period. A share of the Company’s previously incurred asbestos-related expenses and future asbestos-related expenses are covered by pre-existing insurance policies. The Company had been engaged in a legal action against the insurance carriers for those policies to recover past expenses and future costs incurred. In March of fiscal 2020, the Company came to a tentative agreement with the insurance carriers to settle its case against them for recovery of a portion of past costs and future costs for asbestos-related legal defense costs. The agreement was finalized during the quarter ended September 30, 2020. The terms of the settlement require the carriers to pay gross defense costs prior to retro-premiums of 65% for future asbestos-related defense costs subject to an annual cap of $1,650,000 for claims covered by the settlement. The reimbursement net of retro-premiums is approximately 47% which resulted in a $1,830,000 increase to the Company’s asbestos liability during the nine months ended December 31, 2020. In addition, the insurance carriers are required to reimburse the Company for past defense costs through the date of the settlement amounting to $3,006,000. Of this amount, $2,842,000 has been paid prior to December 31, 2020 with the remaining expected to be paid before the end of fiscal 2021. The reimbursement for past cost is recorded net of a contingent legal fee of $1,500,000 which was paid in the third quarter of fiscal 2021. Further, the insurance carriers accept 100% coverage for indemnity costs related to all covered cases. Estimates of the future cost sharing have been included in the loss reserve calculation as of December 31, 2020 and March 31, 2020. The Company has recorded a receivable for the estimated future cost sharing in Other assets in the Condensed Consolidated Balance Sheet at December 31, 2020 in the amount of $8,391,000, which offsets its asbestos reserves. The Company is also involved in other unresolved legal actions that arise in the normal course of business. The most prevalent of these unresolved actions involve disputes related to product design, manufacture and performance liability. The Company's estimation of its product-related aggregate liability that is probable and estimable, in accordance with U.S. generally accepted accounting principles approximates $5,234,000, which has been reflected as a liability in the Condensed Consolidated Statement of Operations as of December 31, 2020. In some cases, we cannot reasonably estimate a range of loss because there is insufficient information regarding the matter. Management believes that the potential additional costs for claims will not have a material effect on the financial condition of the Company or its liquidity, although the effect of any future liabilities recorded could be material to earnings in a future period. The following loss contingencies relate to the Company’s Magnetek subsidiary: Product Liability Magnetek has been named, along with multiple other defendants, in asbestos-related lawsuits associated with business operations previously acquired but which are no longer owned. During Magnetek's ownership, none of the businesses produced or sold asbestos-containing products. For such claims, Magnetek is uninsured and either contractually indemnified against liability, or contractually obligated to defend and indemnify the purchaser of these former business operations. The Company aggressively seeks dismissal from these proceedings. Based on actuarial information, the asbestos-related liability including legal costs is estimated to be approximately $626,000 which has been reflected as a liability in the Condensed Consolidated Balance Sheet at December 31, 2020. Litigation-Other In October 2010, Magnetek received a request for indemnification from Power-One, Inc. ("Power-One") for an Italian tax matter arising out of the sale of Magnetek's power electronics business to Power-One in October 2006. With a reservation of rights, Magnetek affirmed its obligation to indemnify Power-One for certain pre-closing taxes. The sale included an Italian company, Magnetek, S.p.A., and its wholly owned subsidiary, Magnetek Electronics (Shenzhen) Co. Ltd. (the “Power-One China Subsidiary”). The tax authority in Arezzo, Italy, issued a notice of audit report in September 2010 wherein it asserted that the Power-One China Subsidiary had its administrative headquarters in Italy with fiscal residence in Italy and, therefore, is subject to taxation in Italy. In November 2010, the tax authority issued a notice of tax assessment for the period of July 2003 to June 2004, alleging that taxes of approximately $2,300,000 (Euro 1,900,000) were due in Italy on taxable income earned by the Power-One China Subsidiary during this period. In addition, the assessment alleges potential penalties together with interest in the amount of approximately $3,200,000 (Euro 2,600,000) for the alleged failure of the Power-One China Subsidiary to file its Italian tax return. The Power-One China Subsidiary filed its response with the provincial tax commission of Arezzo, Italy in January 2011. A hearing before the Tax Court was held in July 2012 on the tax assessment for the period of July 2003 to June 2004. In September 2012, the Tax Court ruled in favor of the Power-One China Subsidiary dismissing the tax assessment for the period of July 2003 to June 2004. In February 2013, the tax authority filed an appeal of the Tax Court's September 2012 ruling. The Regional Tax Commission of Florence heard the appeal of the tax assessment dismissal for the period of July 2003 to June 2004 and thereafter issued its ruling finding in favor of the tax authority. Magnetek believes the court’s decision was based upon erroneous interpretations of the applicable law and appealed the ruling to the Italian Supreme Court in April 2015. The tax authority in Arezzo, Italy also issued a tax inspection report in January 2011 for the periods July 2002 to June 2003 and July 2004 to December 2006 claiming that the Power-One China Subsidiary failed to file Italian tax returns for the reported periods. In August 2012, the tax authority in Arezzo, Italy issued notices of tax assessment for the periods July 2002 to June 2003 and July 2004 to December 2006, alleging that taxes of approximately $8,200,000 (Euro 6,700,000) were due in Italy on taxable income earned by the Power-One China Subsidiary together with an allegation of potential penalties in the amount of approximately $3,400,000 (Euro 2,800,000) for the alleged failure of the Power-One China Subsidiary to file its Italian tax returns. On June 3, 2015, the Tax Court ruled in favor of the Power-One China Subsidiary dismissing the tax assessments for the periods of July 2002 to June 2003 and July 2004 to December 2006. On July 27, 2015, the tax authority filed an appeal of the Tax Court's ruling of June 3, 2015. In May 2016, the Regional Tax Court of Florence rejected the appeal of the tax authority and at the same time canceled the notices of assessment for the fiscal years of 2004/2005 and 2005/2006. The tax authority had up to six months to appeal the decision. In December 2016, Magnetek was served by the Italian Revenue Service with two appeals to the Italian Supreme Court regarding the two positive judgments on the tax assessments for the fiscal periods 2004/2005 and 2005/2006. In March 2017, the tax authority rejected the appeal of the assessment for 2005/2006 fiscal year. The tax authority had until October 2017 to appeal this decision. In October 2017, Magnetek was served by the Italian Revenue Service with an appeal to the Italian Supreme Court against the positive judgment on the tax assessment for fiscal year 2005/2006. In November 2017 Magnetek filed a memorandum with the Italian Revenue Service and the Italian Supreme Court in response to the appeal made by the tax authority. In February 2018 an appeal hearing was held at the Regional Tax Court of Florence regarding the Italian tax authority's claim for taxes due for fiscal 2002/2003. In October 2018 Magnetek was served by the Italian Revenue Service with an appeal to the Italian Supreme Court against the positive judgment on the tax assessment for fiscal year 2002/2003. In November 2018 Magnetek filed a memorandum with the Italian Supreme Court in response to the appeal made by the tax authority. The Company believes it will be successful and does not expect to incur a liability related to these assessments. Environmental Matters From time to time, Magnetek has taken action to bring certain facilities associated with previously owned businesses into compliance with applicable environmental laws and regulations. Upon the subsequent sale of certain businesses, Magnetek agreed to indemnify the buyers against environmental claims associated with the divested operations, subject to certain conditions and limitations. Remediation activities, including those related to indemnification obligations, did not involve material expenditures during the first nine months of fiscal year 2021. Magnetek has also been identified by the United States Environmental Protection Agency and certain state agencies as a potentially responsible party for cleanup costs associated with alleged past waste disposal practices at several previously utilized, owned or leased facilities and offsite locations. Its remediation activities as a potentially responsible party were not material in the first nine months of fiscal year 2021. Although the materiality of future expenditures for environmental activities may be affected by the level and type of contamination, the extent and nature of cleanup activities required by governmental authorities, the nature of Magnetek's alleged connection to the contaminated sites, the number and financial resources of other potentially responsible parties, the availability of indemnification rights against third parties and the identification of additional contaminated sites, Magnetek's estimated share of liability, if any, for environmental remediation, including its indemnification obligations, is not expected to be material. In 1986, Magnetek acquired the stock of Universal Manufacturing Corporation (“Universal”) from a predecessor of Fruit of the Loom (“FOL”), and the predecessor agreed to indemnify Magnetek against certain environmental liabilities arising from pre-acquisition activities at a facility in Bridgeport, Connecticut. Environmental liabilities covered by the indemnification agreement included completion of additional cleanup activities, if any, at the Bridgeport facility and defense and indemnification against liability for potential response costs related to offsite disposal locations. Magnetek's leasehold interest in the Bridgeport facility was assigned to the buyer in connection with the sale of Magnetek's transformer business in June 2001. FOL, the successor to the indemnification obligation, filed a petition for Reorganization under Chapter 11 of the Bankruptcy Code in 1999 and Magnetek filed a proof of claim in the proceeding for obligations related to the environmental indemnification agreement. Magnetek believes that FOL had substantially completed the clean-up obligations required by the indemnification agreement prior to the bankruptcy filing. In November 2001, Magnetek and FOL entered into an agreement involving the allocation of certain potential tax benefits and Magnetek withdrew its claims in the bankruptcy proceeding. Magnetek further believes that FOL's obligation to the state of Connecticut was not discharged in the reorganization proceeding. In January 2007, the Connecticut Department of Environmental Protection (“DEP”) requested parties, including Magnetek, to submit reports summarizing the investigations and remediation performed to date at the site and the proposed additional investigations and remediation necessary to complete those actions at the site. DEP requested additional information relating to site investigations and remediation. Magnetek and the DEP agreed to the scope of the work plan in November 2010. The Company has recorded a liability of $403,000 included in the amount specified above, related to the Bridgeport facility, representing the best estimate of future site investigation costs and remediation costs which are expected to be incurred in the future. The Company has recorded total liabilities of $581,000 for all environmental matters related to Magnetek in the consolidated financial statements as of December 31, 2020 on an undiscounted basis. In September of 2017, Magnetek received a request for defense and indemnification from Monsanto Company, Pharmacia, LLC, and Solutia, Inc. (collectively, “Monsanto”) with respect to: (1) lawsuits brought by plaintiffs claiming that Monsanto manufactured polychlorinated biphenyls ("PCBs"), exposure to which allegedly caused injury to plaintiffs; and (2) lawsuits brought by municipalities and municipal entities claiming that Monsanto should be responsible for a variety of damages due to the presence of PCBs in bodies of water in those municipalities and/or in water treated by those municipal entities. Monsanto claims to be entitled to defense and indemnification from Magnetek under a so-called “Special Undertaking” apparently executed by Universal in January of 1972, which purportedly required Universal to defend and indemnify Monsanto from liabilities “arising out of or in connection with the receipt, purchase, possession, handling, use, sale or disposition of” PCBs by Universal. Magnetek has declined Monsanto’s tender, and believes that it has meritorious legal and factual defenses to the demands made by Monsanto. Magnetek is vigorously defending against those demands and has commenced litigation to, among other things, declare the Special Undertaking void and unenforceable. Monsanto has, in turn, commenced an action to enforce the Special Undertaking. Magnetek intends to continue to vigorously prosecute its declaratory judgment action and to defend against Monsanto’s action against it. Discovery is currently underway in both actions. We cannot reasonably estimate a potential range of loss with respect to Monsanto’s tender because there is insufficient information regarding the underlying matters. Management believes, however, that the potential additional legal costs related to such matters will not have a material effect on the financial condition of the Company or its liquidity, although the effect of any future liabilities recorded could be material to earnings in a future period. As of December 31, 2020, the Company has recorded a reserve of $60,000 for legal costs incurred to date and expected to be incurred related to this matter. Separately, the Company previously filed suit against Travelers in District Court seeking coverage under insurance policies in the name of Magnetek’s predecessor Universal Manufacturing. In July 2019, the District Court ruled that Travelers is obligated to defend Magnetek under these policies in connection with Magnetek’s litigation against Monsanto. The Court held that Monsanto’s claims against Magnetek fall within the insuring agreement of the Travelers policies and that none of the policy exclusions precluded the possibility of coverage. The Court also held that Travelers prior settlements with other insureds under the policies did not cut off or release Magnetek’s rights under the policies. Travelers moved for reconsideration of that order and the Court denied the motion to reconsider on September 22, 2020. As a result the Court’s prior order granting Magnetek partial summary judgment and requiring Travelers’ to reimburse Magnetek’s defense costs to date and fund its defense costs moving forward is now binding, subject to Travelers right to appeal a final order.

Income Taxes

Income Tax Disclosure [Abstract]
Income Tax Disclosure	13. Income Taxes Income tax expense (benefit) as a percentage of income (loss) from continuing operations before income tax expense was 9% and 13% in the quarters ended December 31, 2020 and December 31, 2019, respectively, and (45)% and 20% for the nine-month periods then ended, respectively. Typically these percentages vary from the U.S. statutory rate of 21% primarily due to varying effective tax rates at the Company's foreign subsidiaries, and the jurisdictional mix of taxable income for these subsidiaries. For the three months ended December 31, 2020, the rates are lower than the U.S. statutory rate as a result of pre-tax losses in certain jurisdictions. For the nine months ended December 31, 2020, the rates are lower than the U.S. statutory rate as a result of the impacts associated with pre-tax losses in the U.S. related to the pension settlement expense recorded of $18,933,000 for the year, the U.S. R&D credit, and the utilization of net operating losses that previously had a full valuation allowance against them. The Company estimates that the effective tax rate related to continuing operations will be approximately (2)% to (4)% for fiscal 2021 resulting from a pre-tax loss primarily due to the termination of one of the Company's U.S. pension plans. Refer to the Company’s consolidated financial statements included in its 2020 10-K for further information on income taxes.

Leases [Abstract]
Lessee, Operating Leases	15. Leases The Company's leases are classified as operating leases and consist of manufacturing facilities, sales offices, distribution centers, warehouses, vehicles, and equipment. For leases with terms greater than twelve months, at lease commencement the Company recognizes a right-of-use ("ROU") asset and a lease liability. The initial lease liability is recognized at the present value of remaining lease payments over the lease term. Leases with an initial term of twelve months or less are not recorded on the Company's Condensed Consolidated Balance Sheet. The Company recognizes lease expense for operating leases on a straight-line basis over the lease term. The Company's leases have lease terms ranging from 1 to 15 years, some of which include options to extend or terminate the lease. The exercise of lease renewal options is at the Company’s sole discretion. When deemed reasonably certain of exercise, the renewal options are included in the determination of the lease term. The Company’s lease agreements do not contain material residual value guarantees or any material restrictive covenants. The following table illustrates the balance sheet classification for ROU assets and lease liabilities (in thousands): Balance sheet classification December 31, 2020 March 31, 2020 Assets Other assets $ 36,310 $ 38,125 Current Accrued liabilities 7,826 6,924 Non-current Other non current liabilities 29,251 31,629 Total liabilities $ 37,077 $ 38,553 Operating lease expense of $2,342,000 and $2,299,000 and $6,953,000 and $6,833,000 for the three and nine months ending December 31, 2020 and December 31, 2019, respectively, is included in income from operations on the Condensed Consolidated Statements of Operations.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Effects of New Accounting Pronouncements	Effects of New Accounting Pronouncements ASU 2016-13 (Topic 326) - Adopted in fiscal 2021 In November 2019, the FASB issued ASU No. 2019-11, "Codification Improvements to Topic 326: Financial Instruments - Credit Losses." The ASU allows, among other aspects, companies to make accounting policy elections to simplify certain aspects of the presentation and measurement of accrued interest on receivables as well as certain practical expedients for disclosure of accrued interest and financial assets secured by collateral maintenance provisions. The ASU was adopted in connection with the adoption of ASU 2016-13 described below. In May 2019, the FASB issued ASU No. 2019-05, "Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief." The ASU allows companies to elect, upon adoption of ASU 2016-13, the fair value option on financial instruments that were previously recorded at amortized cost and are within the scope of ASC 326-20 if the instruments are eligible for the fair value option under ASC 825-10. The ASU was adopted in connection with the adoption of ASU 2016-13 described below. In November 2018, the FASB issued ASU No. 2018-19, "Codification Improvements to Topic 326: Financial Instruments - Credit Losses." The ASU changes the effective date of ASU 2016-13, Financial Instruments - Credit Losses, to fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). The standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. ASU 2016-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. The Company adopted this standard and all related standards effective April 1, 2020. Refer to Note 3 (Revenue & Receivables) for the transition impact and further details. Other Topics adopted in fiscal 2021 In August 2018, the FASB issued ASU No. 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820)." The ASU changes the fair value measurement disclosure requirements including new, eliminated, and modified disclosure requirements of ASC 820. For instance, the ASU requires the addition of disclosures for Level 3 fair value measurements with unrealized gains and losses included in other comprehensive income and disclosure of the range of the weighted average used to develop significant unobservable inputs for Level 3 measurements. The ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those years, with early adoption permitted for any eliminated or modified disclosures. The Company adopted this standard effective April 1, 2020 and the standard did not have a material impact on the financial statements for the three and nine months ended December 31, 2020. Other Topics not yet adopted In August 2020, the U.S. Securities and Exchange Commission ("SEC") issued its rule Modernization of Regulation S-K Items, which modernizes the disclosure requirements in Regulation S-K, Item 101, “Description of Business”; Item 103, “Legal Proceedings”; and Item 105, “Risk Factors.” The SEC stated that the final rule is intended to improve the readability of disclosures, reduce repetition, and eliminate immaterial information, thereby simplifying compliance for registrants and making disclosures more meaningful for investors. The SEC rule was effective November 9, 2020 and the Company will adopt the rule in conjunction with its Form 10-K. In March 2020, the FASB issued ASU No. 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." The ASU is elective and is relief to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. Optional expedients are provided for contract modification accounting under topics such as debt, leases, and derivatives. The optional amendments are effective for all entities as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020 through December 31, 2022. We are currently evaluating the impact the standard will have on our consolidated financial statements if we chose to elect.
