Accounting Policies [Abstract]
Advertising	Advertising Costs associated with advertising are expensed as incurred and are included in Selling expense in the Consolidated Statements of Operations. Advertising expenses were $2,410,000, $999,000, and $1,648,000 in fiscal 2022, 2021, and 2020, respectively. The increase in fiscal 2022 was due to increased spending as business returns to pre-pandemic COVID-19 levels as well as the acquisitions of Dorner and Garvey.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers as cash equivalents all highly liquid investments with an original maturity of three months or less.
Concentration of Labor	Concentrations of Labor Approximately 6% of the Company’s employees are represented by two separate U.S. collective bargaining agreements which expire in May 2024 and September 2024. We also have various labor agreements with our non-U.S. employees that we negotiate from time to time.
Consolidation	Consolidation These consolidated financial statements include the accounts of the Company and its global subsidiaries; all significant intercompany accounts and transactions have been eliminated.
Schedule of Equity Method Investments [Line Items]	Equity Method Investment The Company has an investment in Eastern Morris Cranes Company Limited ("EMC") whose principal activity is to manufacture various electrical overhead traveling cranes. This investment represents a minority ownership interest that is accounted for under the equity method of accounting since the Company has significant influence over the investee. As a result, the Company records its portion of the gains and losses incurred by this entity in Investment (income) loss in the Consolidated Statements of Operations.
Foreign Currency Translations	Foreign Currency Translations The Company translates foreign currency financial statements as described in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 830, “Foreign Currency Matters.” Under this method, all items of income and expense are translated to U.S. dollars at average exchange rates during the year. All assets and liabilities are translated to U.S. dollars at the year-end exchange rate. Gains or losses on translations are recorded in accumulated other comprehensive loss in the shareholders’ equity section of the balance sheet. The functional currency is the foreign currency in which the foreign subsidiaries conduct their business. Gains and losses from foreign currency transactions are reported in foreign currency exchange loss (gain).
Goodwill	Goodwill Goodwill is not amortized but is tested for impairment at least annually, or more frequently if indicators of impairment exist, 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 and interdependencies 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 reporting segment level as defined under ASC Topic 280-10-50-10 “Segment Reporting – Disclosure.” As of March 31, 2022, the Company’s one segment is subdivided into three reporting units. Further, the Company adopted ASU No. 2017-04, "Simplifying the Test for Goodwill Impairment (Topic 350)," in fiscal 2018, therefore, is no longer required to compare the implied fair value of goodwill with its carrying value amount as part of step two of the goodwill test. An impairment charge is the amount by which the carrying value is greater than the reporting unit's fair value. When the Company evaluates the potential for goodwill impairment, it assesses a range of qualitative factors including, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for its products and services, regulatory and political developments, entity specific factors such as strategy and changes in key personnel, and overall financial performance. If, after completing this assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value or if economic or other business factors indicate that the fair value of our reporting units may have declined since our last quantitative test, the Company performs a quantitative test. To perform the quantitative impairment test, the Company uses the discounted cash flow method and a market-based valuation model to estimate the fair value of the reporting units. The discounted cash flow method incorporates various assumptions, the most significant being projected revenue growth rates, operating profit margins and cash flows, the terminal growth rate, and the discount rate. The Company projects revenue growth rates, operating margins and cash flows based on each reporting unit's current business, expected developments, and operational strategies over a five-year period. In estimating the terminal growth rates, the Company considers its historical and projected results, as well as the economic environment in which its reporting units operate. The discount rates utilized for each reporting unit reflect the Company's assumptions of marketplace participants' cost of capital and risk assumptions, both specific to the reporting unit and overall in the economy. The Company performed its qualitative assessment as of February 28, 2022 and determined that the quantitative goodwill impairment test was not required for the Rest of Products, Duff-Norton and Precision Conveyance reporting units. Based on various conditions in the current fiscal year, such as financial performance, macroeconomic conditions, and other company specific events, it was determined that the Rest of Products, Duff-Norton's and Prevision Conveyance reporting units fair value were not more likely than not less than its applicable carrying value. See Note 9 for further discussion of goodwill and intangible assets.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company assesses impairment of its long-lived assets in accordance with the provisions of ASC Topic 360 “Property, Plant, and Equipment.” This statement requires long-lived assets, such as property and equipment and purchased intangibles subject to amortization, to be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset group to estimated undiscounted future cash flows expected to be generated by the asset group over its remaining useful life. If the carrying amount of an asset group exceeds its estimated future cash flows, an impairment charge is recognized equal to the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. The fair values are determined in accordance with ASC 820. In assessing long-lived assets for an impairment loss, assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Asset grouping requires a significant amount of judgment. Accordingly, facts and circumstances will influence how asset groups are determined for impairment testing. In assessing long-lived assets for impairment, management considered the Company’s product line portfolio, customers and related commercial agreements, labor agreements and other factors in grouping assets and liabilities at the lowest level for which identifiable cash flows are independent. The Company considers projected future undiscounted cash flows, trends and other factors in its assessment of whether impairment conditions exist. While the Company believes that its estimates of future cash flows are reasonable, different assumptions regarding such factors as future production volumes, customer pricing, economics, and productivity and cost initiatives, could significantly affect its estimates. In determining fair value of long-lived assets, management uses management estimates, discounted cash flow calculations, and appraisals where necessary. There were no impairments recorded related to long-lived assets in the current year.
Intangible Assets	Intangible Assets At acquisition, the Company estimates and records the fair value of purchased intangible assets which primarily consist of trade names, customer relationships, and technology. The fair values are estimated based on management’s assessment as well as independent third party appraisals. Such valuations may include a discounted cash flow of anticipated revenues resulting from the acquired intangible asset. Amortization of intangible assets with finite lives is recognized over their estimated useful lives using an amortization method that reflects the pattern in which the economic benefits of the intangible assets are consumed or otherwise realized. The straight line method is used for customer relationships. As a result of the negligible attrition rate in our customer base, the difference between the straight line method and attrition method is not considered significant. The estimated useful lives for our intangible assets range from 1 to 25 years. Similar to goodwill, indefinite-lived intangible assets (including trademarks on our acquisitions) are tested for impairment on an annual basis. When the Company evaluates the potential for impairment of intangible assets, it assesses a range of qualitative factors including, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for its products and services, regulatory and political developments, entity specific factors such as strategy and changes in key personnel, and overall financial performance. If, after completing this assessment, it is determined that it is more likely than not that the fair value of an indefinite-lived intangible asset is greater than its carrying value, we conclude that the indefinite-lived intangible asset is not impaired. If, after completing this assessment, it is determined that it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value or if economic or other business factors indicate that the fair value of our indefinite-lived intangible assets may have declined since our last quantitative test, the Company performs a new quantitative test. The methodology used to value trademarks is the relief from royalty method. The recorded book value of these trademarks in excess of the calculated fair value triggers an impairment. The key estimate used in this calculation consists of an overall royalty rate applied to the sales covered by the trademark. After performing a qualitative assessment as of February 28, 2022, it was determined that the trademarks were not impaired.
Inventories	Inventories Inventories are valued at the lower of cost and net realizable value. Cost of approximately 35% of inventories at March 31, 2022 and 39% at March 31, 2021 have been determined using the LIFO (last-in, first-out) method. Costs of other inventories have been determined using the FIFO (first-in, first-out) or average cost method. FIFO cost approximates replacement cost. Costs in inventory include components for direct labor and overhead costs.
Marketable Securities	Marketable Securities The Company’s marketable securities, which consist of equity and fixed income securities, are recorded at fair value. Under ASU 2016-01 all equity investments (including certain fixed income securities) in unconsolidated entities are measured at fair value through earnings. Therefore, gains and losses on marketable securities are realized within Investment (income) loss on the Consolidated Statements of Operations. Estimated fair value is based on published trading values at the balance sheet dates. The cost of securities sold is based on the specific identification method. Interest and dividend income are also included in Investment (income) loss on the Consolidated Statements of Operations. The marketable securities are carried as long-term assets since they are held for the settlement of the Company’s general and products liability insurance claims filed through CM Insurance Company, Inc., a wholly owned captive insurance subsidiary. The marketable securities are not available for general working capital purposes.
Property, Plant and Equipment	Property, Plant, and Equipment Property, plant, and equipment are stated at cost and depreciated principally using the straight-line method over their respective estimated useful lives (buildings and building equipment—15 to 40 years; machinery and equipment—3 to 18 years). When depreciable assets are retired, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in operating results.
Research and Development	Research and Development Consistent with prior periods, the Company continues to account for R&D expenses in accordance with the provisions of ASC 730 and are expensed as incurred.
Revenue Recognition, Accounts Receivable and Concentration of Credit Risk	Revenue Recognition, Accounts Receivable, and Concentration of Credit Risk The Company adopted ASC 606, "Revenue from Contracts with Customers," in fiscal 2019. 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 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. The Company generally recognizes revenue for customer 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. For both standard products and custom engineered products, the transaction price is based upon the price stated in either the purchase order or contract. Refer to Note 4 for further details. Additionally, the Company performs ongoing credit evaluations of its customers’ financial condition, but generally does not require collateral to support customer receivables. The credit risk is controlled through credit approvals, limits, and monitoring procedures. Accounts receivables are reported at net realizable value and do not accrue interest. The Company establishes an allowance for doubtful accounts based upon factors surrounding 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. The Company does not routinely permit customers to return product. However, sales returns are permitted in specific situations and typically include a restocking charge or the purchase of additional product. As a result of ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," effective in fiscal 2021, the Company has updated its existing allowance for doubtful accounts policy to comply with the new standard.
Shipping and Handling Costs	Shipping and Handling Costs Shipping and handling costs are a component of cost of products sold.
Share-based Compensation	Stock-Based Compensation The Company records stock-based compensation in accordance with ASC Topic 718, “Compensation – Stock Compensation.” This standard requires all equity-based payments to employees, including grants of employee stock options, to be recognized in the Consolidated Statements of Operations based on the grant date fair value of the award. Stock compensation expense is included in Cost of products sold, Selling, and General and administrative expense depending on the nature of the service of the employee receiving the award. The Company uses a straight-line method of attributing the value of stock compensation expense, subject to minimum levels of expense, based on vesting. See Note 15 for further discussion of stock-based compensation.
Leases	Leases All leases are reviewed for operating or finance classification at their inception. Rent expense for leases that contain scheduled rent increases is recognized on a straight-line basis over the lease term. As described in Note 18, the Company adopted ASC 842, "Leases," effective April 1, 2019 whereas leases with terms greater than twelve months are recorded on the balance sheet as a right-of-use ("ROU") asset and corresponding lease liability. Refer to Note 18 for further details.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Warranties	Warranties The Company offers warranties for certain products it sells. The specific terms and conditions of those warranties vary depending upon the product sold and the country in which the Company sold the product. As noted in the Revenue Recognition note (Note 4), 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 are assurance-type warranties that do not qualify as separate performance obligations under ASC 606. The Company estimates the costs that may be incurred under its standard warranties, based largely upon actual warranty repair costs history, and records a liability in the amount of such costs in the month that revenue is recognized. The resulting accrual balance is reviewed during the year. Factors that affect the Company’s warranty liability include the number of units sold, historical and anticipated rate of warranty claims, and cost per claim. Changes in the Company’s product warranty accrual are as follows:
