Description of Business	Description of Business
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position of Columbus McKinnon Corporation (the Company) at December 31, 2014, the results of its operations for the three and nine month periods ended December 31, 2014 and December 31, 2013, and cash flows for the nine months ended December 31, 2014 and December 31, 2013, have been included. Results for the period ended December 31, 2014 are not necessarily indicative of the results that may be expected for the year ending March 31, 2015. The balance sheet at March 31, 2014 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Columbus McKinnon Corporation annual report on Form 10-K for the year ended March 31, 2014.
	The Company is a leading designer, marketer and manufacturer of material handling products and services which efficiently and safely move, lift, position and secure material. Key products include hoists, rigging tools, cranes, and actuators. The Company’s material handling products are sold globally, principally to third party distributors through diverse distribution channels, and to a lesser extent directly to end-users. During the three and nine months ended December 31, 2014, approximately 59% and 58% of sales were to customers in the U.S, respectively.

Acquisitions	Acquisitions
	On June 1, 2013, the Company acquired 100% of the outstanding common shares of Hebetechnik Gesellschaft m.b.H (“Hebetechnik”) located in Austria, a privately owned company with annual sales of approximately $10,000,000. Hebetechnik has been a value-added partner of the Company in the lifting industry in the Austrian market for over 20 years. The results of Hebetechnik are included in the Company’s condensed consolidated financial statements from the date of acquisition. The acquisition of Hebetechnik is not considered significant to the Company’s consolidated financial position and results of operations.
	The acquisition of Hebetechnik was funded with existing cash. The purchase price has been allocated to the assets acquired and liabilities assumed as of the date of acquisition.  The excess consideration of $5,324,000 was recorded as goodwill.  The identifiable intangible asset consisted of order backlog at the date of the acquisition and was estimated to have a three month useful life. Goodwill recorded in connection with the acquisition is deductible for Austrian tax purposes. The assignment of purchase consideration to the assets acquired and liabilities assumed was as follows (in thousands):
	Working capital	$	212
	Other current assets	58
	Property, plant and equipment	446
	Goodwill	5,324
	Long term debt	(193		)
	Total	$	5,847
	On February 28, 2014 the Company acquired 100% of the outstanding common shares of Unified Industries, Inc. (“Unified”) located in Howell, Michigan, a privately-owned company with annual sales of approximately $13,000,000. Unified designs, manufacturers and markets overhead aluminum light rail workstations primarily used in automotive and other industrial applications. Unified's products are a natural extension of the Company's hoist portfolio and are expected to broaden the scope of the Company's bundled product solutions. The results of Unified are included in the Company’s consolidated financial statements from the date of acquisition. The acquisition of Unified is not considered significant to the Company’s consolidated financial position and results of operations.
	The acquisition of Unified was funded with existing cash. The purchase price has been preliminarily allocated to the assets acquired and liabilities assumed as of the date of acquisition. The excess consideration of $6,980,000 was recorded as goodwill. The identifiable intangible assets acquired include engineered drawings of $4,960,000, customer relationships of $2,300,000, trademark and trade names of $1,200,000, backlog of $185,000, and non-compete agreements of $14,000. The weighted average life of the acquired identifiable intangible assets subject to amortization was estimated at 20.3 years at the time of acquisition. Goodwill recorded in connection with the acquisition is not deductible for U.S. income tax purposes.
	The preliminary assignment of purchase consideration to the assets acquired and liabilities assumed is as follows (in thousands):
	Working capital	$	3,854
	Property, plant and equipment	210
	Identifiable intangible assets	8,659
	Other long term assets	97
	Other long term liabilities	(3,293		)
	Goodwill	6,980
	Total	$	16,507
	On December 30, 2014 the Company acquired 100% of the outstanding common shares of Stahlhammer Bommern GmbH (“STB”) located in Hamm, Germany, a privately-owned company with annual sales of approximately $17,800,000. STB manufactures a large range of lifting tools and forged parts that are able to withstand particularly heavy, static and dynamic loads, including single and ramshorn lifting hooks. The Company believes STB is a strong strategic fit allowing further expansion of the rigging business globally. The results of STB are included in the Company’s consolidated financial statements from the date of acquisition. The acquisition of STB is not considered significant to the Company’s consolidated financial position and results of operations.
	The acquisition of STB was funded with existing cash. The purchase price has been preliminarily allocated to the assets acquired and liabilities assumed as of the date of acquisition. At December 31, 2014 the fair values of the assets acquired and liabilities assumed have been preliminarily estimated based on their carrying values due to the proximity of the acquisition to the quarter end date and pending the finalization of their fair values. Revisions to these estimates as fair values are finalized will be reflected in the financial statements throughout the measurement period. The excess consideration of $14,623,000 has preliminarily been recorded as goodwill. Goodwill recorded in connection with the acquisition is not deductible for German income tax purposes.
	The preliminary assignment of purchase consideration to the assets acquired and liabilities assumed is as follows (in thousands):
	Working capital	$	9,100
	Property, plant and equipment	8,597
	Other liabilities	(6,570		)
	Goodwill	14,623
	Total	$	25,750
	In connection with the acquisition of STB, the Company withheld $5,819,000 to be paid to the seller at upon satisfaction of certain conditions. Of this amount, $1,210,000 is expected to be paid to the seller within one year of the acquisition and the remaining $4,609,000 is expected to be paid to the seller in a time period exceeding one year of the acquisition. The Company has recorded assets on its condensed consolidated balance sheet at December 31, 2014 of current restricted cash of $1,210,000 within prepaid expenses and other and long term restricted cash of $4,609,000 in other assets. Further, the Company has recorded a short term liability to the seller of $1,210,000 within accrued liabilities and a long term liability to the seller of $4,609,000 within other non current liabilities.
	For our acquisitions, goodwill represents future economic benefits arising from other assets acquired that do not meet the criteria for separate recognition apart from goodwill, including assembled workforce, growth opportunities and increased presence in the markets served by the target companies.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“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 Topic 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.
	When valuing its derivative portfolio, the Company primarily uses readily observable market data in conjunction with internally developed discounted cash flow valuation models and, consequently, the fair value of the Company’s derivatives is based on Level 2 inputs.  The Company uses quoted prices in an inactive market when valuing its Subordinated Debt, represented by the 7 7/8% Notes due 2019, registered under the Securities Act of 1933, as amended (7 7/8% Notes) and, consequently, the fair value is based on Level 2 inputs. The carrying value of the Company’s senior debt approximates fair value based on current market interest rates for debt instruments of similar credit standing and, consequently, its fair value is 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

	Senior debt	(3,608		)	—		(3,608		)	—
	The Company did not have any nonfinancial assets and liabilities that are recognized at fair value on a recurring basis.
	The carrying amount of these financial assets and liabilities are the same as their fair value with the exception of the subordinated debt whose carrying value is a liability of $148,890,000 at December 31, 2014 and $148,685,000 at March 31, 2014.
	Interest and dividend income on marketable securities are recorded in investment (income) loss.  Changes in the fair value of derivatives are recorded in foreign currency exchange (gain) loss or other comprehensive 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.
	Assets and liabilities that were measured on a non-recurring basis during the nine months ended December 31, 2014 and year ended March 31, 2014 include assets and liabilities acquired in connection with the acquisitions of Hebetechnik, Unified, and STB described in Note 2. The estimated fair values allocated to the assets acquired and liabilities assumed relied upon fair value measurements based primarily on Level 3 inputs. The valuation techniques used to allocate fair values to working capital items; property, plant, and equipment; and identifiable intangible assets included the cost approach, market approach, and other income approaches.  The valuation techniques relied on a number of inputs which included the cost and condition of property, plant, and equipment and forecasted net sales and income. For STB, the fair values of the assets acquired and liabilities assumed have been preliminarily estimated based on their carrying values due to the proximity of the acquisition date to the quarter end date of December 31, 2014. Revisions to these estimates as fair value calculations are completed will be reflected in the financial statements throughout the measurement period. For Unified, significant valuation inputs included an attrition rate of 8% for customer relationships, an engineering cost per hour of $57.20 for the engineered drawings, and a royalty rate of 1.5% for trademark and trade names. For Hebetechnik, significant valuation inputs included a weighted average cost of capital of 12.3%.

	At cost - FIFO basis:
	Raw materials	$	69,936		$	55,072

	LIFO cost less than FIFO cost	(18,388		)	(19,483		)
	Net inventories	$	107,421		$	97,576
	An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. 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.

Marketable Securities [Abstract]
Marketable Securities	Marketable Securities
	All of the Company’s marketable securities, which consist of equity securities and fixed income securities, have been classified as available-for-sale securities and are therefore recorded at their fair values with the unrealized gains and losses, net of tax, reported in accumulated other comprehensive loss in the shareholders’ equity section of the condensed consolidated balance sheet unless unrealized losses are deemed to be other-than-temporary. In such instances, the unrealized losses are reported in the condensed consolidated statements of operations and retained earnings within investment income. 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 in the condensed consolidated statements of operations and retained earnings.
	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.
	In accordance with ASC Topic 320-10-35-30 “Investments – Debt & Equity Securities – Subsequent Measurement,” the Company reviews its marketable securities for declines in market value that may be considered other-than-temporary. The Company generally considers market value declines to be other-than-temporary if there are declines for a period longer than six months and in excess of 20% of original cost, or when other evidence indicates impairment.  We also consider the nature of the underlying investments, our intent and ability to hold the investments until their market values recover, and other market conditions in making this assessment. There were no other-than-temporary impairments for the three and nine months ended December 31, 2014 or December 31, 2013.
	During the nine months ended December 31, 2014, certain investments that were previously written down were sold at a gain of $58,000. There were no such gains or losses recorded for the nine months ended December 31, 2013.
	The following is a summary of available-for-sale securities at December 31, 2014 (in thousands):

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets
	Goodwill is not amortized but is 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 reporting segment level as defined under ASC Topic 280-10-50-10 “Segment Reporting – Disclosure.” The Company has five reporting units.  Only three of the five reporting units carried goodwill at December 31, 2014 and March 31, 2014.
	When we evaluate the potential for goodwill impairment, we assess a range of qualitative factors including, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for our 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, we proceed to a two-step impairment test.
	In accordance with ASC Topic 350-20-35-3, the measurement of impairment of goodwill consists of two steps. In the first step, the Company compares the fair value of each reporting unit to its carrying value. As part of the impairment analysis, the Company determines the fair value of each of its reporting units with goodwill using the income approach. The income approach uses a discounted cash flow methodology to determine fair value. This methodology recognizes value based on the expected receipt of future economic benefits. Key assumptions in the income approach include a free cash flow projection, an estimated discount rate, a long-term growth rate and a terminal value. These assumptions are based upon the Company’s historical experience, current market trends and future expectations.
	We performed our qualitative assessment during the fourth quarter of fiscal year 2014 and determined that it was not more likely than not that the fair value of each of its reporting units with goodwill, other than Duff-Norton, was less than that its applicable carrying value. Accordingly, the Company did not perform the two-step goodwill impairment test for any of its reporting units other than the Duff-Norton reporting unit. The Company performed step one of the two-step impairment test for the Duff-Norton reporting unit. Based on the results of the two-step impairment test during the fourth quarter of fiscal 2014, the Company determined that the Duff-Norton reporting unit's fair value was not less than its applicable carrying value.
	Future impairment indicators, such as declines in forecasted cash flows, may cause additional significant impairment charges. Impairment charges could be based on such factors as changes in the Company’s stock price, forecasted cash flows, assumptions used, control premiums or other variables.
	A summary of changes in goodwill during the nine months ended December 31, 2014 is as follows (in thousands):
	Balance at April 1, 2014	$	119,303
	Acquisition of STB (see Note 2)	14,623

	Balance at December 31, 2014	$	130,523
	Identifiable intangible assets acquired in a business combination are amortized over their useful lives unless their useful lives are indefinite, in which case those intangible assets are tested for impairment annually (or upon identification of impairment indicators) and not amortized until their lives are determined to be finite.
	Identifiable intangible assets are summarized as follows (in thousands):

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments
	The Company uses derivative instruments to manage selected foreign currency 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, the effective portion of changes in the fair value of the derivative is recorded as accumulated other comprehensive gain (loss), or “AOCL,” and is reclassified to earnings when the underlying transaction has an impact on earnings. The ineffective portion of changes in the fair value of the derivative is reported in foreign currency exchange (gain) loss in the Company’s condensed consolidated statement of operations and retained earnings. For derivatives not classified as cash flow hedges, all changes in market value are recorded as a foreign currency exchange (gain) loss in the Company’s condensed consolidated statements of operations and retained earnings. The cash flow effects of derivatives are reported within net cash provided by operating activities.
	The Company has a foreign currency forward agreement in place to offset changes in the value of an intercompany loan to a foreign subsidiary due to changes in foreign exchange rates. The notional amount of this derivative is $590,000 and the contract matures on April 15, 2016. This contract is marked to market each balance sheet date and is not designated as a hedge.
	The Company has foreign currency forward agreements in place to hedge changes in the value of recorded foreign currency assets and liabilities due to changes in foreign exchange rates at the settlement date. The notional amount of those derivatives is $356,000 and all contracts mature within two months. These contracts are marked to market each balance sheet date and are not designated as hedges.
	The Company has foreign currency forward agreements that are designated as cash flow hedges to hedge a portion of forecasted inventory purchases denominated in a foreign currency. The notional amount of those derivatives is $472,000 and all contracts mature within five months of December 31, 2014.
	The Company has derivative contracts with one counterparty as of December 31, 2014. The Company is exposed to credit losses in the event of non performance by the counterparty on its financial instruments. The counterparty has an investment grade credit rating. The Company anticipates that the counterparty will be able to fully satisfy its obligations under the contracts.
	The Company's agreements with its foreign exchange contract counterparty contain provisions pursuant to which the Company could be declared in default of its derivative obligations. As of December 31, 2014, the Company had not posted any collateral related to these agreements. If the Company had breached any of these provisions as of December 31, 2014, it could have been required to settle its obligations under these agreements at amounts which approximate the December 31, 2014 fair values reflected in the table below. During the nine months ended December 31, 2014, the Company was not in default of any of its derivative obligations.
	From its December 31, 2014 balance of accumulated other comprehensive loss, the Company expects to reclassify approximately $58,000 out of accumulated other comprehensive loss during the next 12 months.

Debt Disclosure [Abstract]
Debt	Debt
	At December 31, 2014 and 2013 the Company has access to borrow funds under a revolving credit facility (Current Revolving Credit Facility). The Current Revolving Credit Facility provides availability up to a maximum of $100,000,000 and has an initial term ending October 31, 2017.
	Provided there is no default, the Company may request an increase in the availability of the Current Revolving Credit Facility by an amount not exceeding $75,000,000, subject to lender approval. The unused portion of the Current Revolving Credit Facility totaled $94,884,000 net of outstanding borrowings of $0 and outstanding letters of credit of $5,116,000 as of December 31, 2014. The outstanding letters of credit at December 31, 2014 consisted of $717,000 in commercial letters of credit and $4,399,000 of standby letters of credit.
	Commitment fees are payable against the unused portion of the revolver based on the applicable rate. Interest on an outstanding borrowing used against the revolver is payable at varying rates depending on the type of outstanding borrowing and its associated interest rate plus its associated applicable rate. The two potential interest rates used are either a Base Rate (equivalent to a fluctuating rate per annum equal to the higher of (a) the Federal Funds Rate plus 1/2 of 1%, (b) the rate of interest in effect for such day as publicly announced from time to time by Bank of America as its "prime rate.", or (c) LIBOR plus 100 basis points or a Eurocurrency Rate (equivalent to LIBOR plus a Mandatory Cost).
	The applicable rate is determined based on the pricing grid in the Current Revolving Credit Facility which varies based on the Company's total leverage ratio and borrowing type at December 31, 2014. The mandatory cost is intended to compensate the lenders for the cost of European banking requirements.
	The Current Revolving Credit Facility is secured by all U.S. inventory, receivables, equipment, real property, subsidiary stock (limited to 65% of non-U.S. subsidiaries) and intellectual property.
	The corresponding credit agreement associated with the Current Revolving Credit Facility places certain debt covenant restrictions on the Company, including certain financial requirements and restrictions on dividend payments, with which the Company was in compliance as of December 31, 2014. Key financial covenants include a minimum fixed charge coverage ratio of 1.25x, a maximum total leverage ratio, net of cash, of 3.50x and maximum annual capital expenditures of $30,000,000.
	At December 31, 2014 and 2013, the Company has outstanding $150,000,000 7 7/8% Senior Subordinated Notes due 2019 registered under the Securities Act of 1933, as amended (7 7/8% Notes). The offering price of the notes was 98.545% of par after adjustment for original issue discount.
	Provisions of the 7 7/8% Notes include, without limitation, restrictions on indebtedness, asset sales, and dividends and other restricted payments. On or after February 1, 2015, the 7 7/8% Notes are redeemable at the option of the Company, in whole or in part, at a redemption price of 103.938%, reducing to 101.969% and 100% on February 1, 2016 and February 1, 2017, respectively and are due February 1, 2019. In the event of a Change of Control (as defined in the indenture for such notes), each holder of the 7 7/8% Notes may require the Company to repurchase all or a portion of such holder’s 7 7/8% Notes at a purchase price equal to 101% of the principal amount thereof. The 7 7/8% Notes are guaranteed by certain existing and future U.S. subsidiaries and are not subject to any sinking fund requirements.
	On January 23, 2015 the Company announced it elected to redeem its 7 7/8% Notes. The 7 7/8% Notes will be redeemed at a redemption price of $1,039.38 per $1,000 of principal amount of 7 7/8% Notes, plus interest on the 7 7/8% Notes up to, but excluding the redemption date of February 23, 2015 (“Redemption Date”). All interest will cease to accrue on and after the Redemption Date.
	On January 23, 2015, the Company entered into a new $150,000,000 senior secured revolving credit facility and established a new $125,000,000 delayed draw senior secured term loan facility. The Company’s Current Revolving Credit Facility was terminated. Both the revolver and the new term loan have five-year terms maturing in 2020. The proceeds from the new term loan and a $25,000,000 draw on the revolver will be used to redeem the 7 7/8% Notes. The Company expects to record an $8,500,000 debt retirement charge, which includes the call premium.
	The gross balances of deferred financing costs were $4,133,000 as of December 31, 2014 and March 31, 2014. The accumulated amortization balances were $1,978,000 and $1,531,000 as of December 31, 2014 and March 31, 2014 respectively.
	On June 22, 2007, the Company recorded a capital lease resulting from the sale and partial leaseback of its facility in Charlotte, NC under a 10 year lease agreement. The Company also has capital leases on certain production machinery and equipment. The outstanding balance on the capital lease obligations of $2,361,000 and $3,608,000 as of December 31, 2014 and March 31, 2014 respectively, are included in senior debt in the consolidated balance sheets.
	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, 2014, unsecured credit lines totaled approximately $6,290,000, of which $0 was drawn. In addition, unsecured lines of $11,553,000 were available for bank guarantees issued in the normal course of business of which $4,124,000 was utilized.
	The current and long term portion of the Company’s other senior debt consists primarily of capital lease obligations and debt acquired in the acquisition of STB.
	In December 2014, the Company acquired STB as described in Note 2.  As part of the acquisition, the Company assumed debt. The outstanding balance of the debt assumed as of December 31, 2014 is $6,254,000. The debt is included in the current portion of long term debt in the consolidating balance sheets as the Company expects to fully pay off the debt in the fourth quarter of fiscal 2015 using current funds.

For the three and nine months ended December 31, 2014 an additional 35,000 in contingently issuable shares were not included in the computation of diluted earnings per share because a performance condition had not yet been met.
	On July 26, 2010, the shareholders of the Company approved the 2010 Long Term Incentive Plan (“LTIP”).  The Company grants share based compensation to eligible participants under the LTIP.  The total number of shares of common stock with respect to which awards may be granted under the plan is 1,250,000 including 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.

Loss Contingency [Abstract]
Loss Contingencies	Loss Contingencies
	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 asbestos-related aggregate liability including related legal costs to range between $6,700,000 and $11,200,000 using actuarial parameters of continued claims for a period of 37 years from December 31, 2014.  The Company's estimation of its asbestos-related aggregate liability that is probable and estimable, in accordance with U.S. generally accepted accounting principles approximates $8,202,000, which has been reflected as a liability in the consolidated financial statements as of December 31, 2014. 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 settlement payments and legal defense costs of approximately $2,000,000 over the next 12 months. Because payment of these costs 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.
	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. 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 $4,594,000, which has been reflected as a liability in the consolidated financial statements as of December 31, 2014. 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.

Income Taxes	Income Taxes
	Income tax expense as a percentage of income from continuing operations before income tax expense was 23% and 12% in the quarter ended December 31, 2014 and December 31, 2013, respectively and 25% for both nine-month periods then ended. Typically these percentages vary from the U.S. statutory rate 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 nine months ended December 31, 2014 income taxes as a percentage of income before income taxes was lower than our projected rate for fiscal 2015 due to a recently issued tax regulation that results in the utilization of certain tax credits relating to previous fiscal years. The credits result in an income tax benefit of $1,431,000 for the nine months ended December 31, 2014 and reduced the effective tax rate by 4%. For the three and nine months ended December 31, 2013 income taxes as a percentage of income before income taxes was not reflective of the U.S. statutory rate due to the reversal of a reserve for an uncertain tax position in the amount of $1,249,000. The reserve for the uncertain tax position was reversed as a result of the expiration of the statute of limitations. We estimate that the effective tax rate related to continuing operations will be approximately 23% to 28% for fiscal 2015.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Effects of New Accounting Pronouncements	Effects of New Accounting Pronouncements
	In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements — Going Concern (Subtopic 205-40).” ASU 2014-15 addresses management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2016. Early adoption is permitted. The Company does not expect that the adoption of this guidance will have a material impact on our consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, "Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period." ASU 2014-12 requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2015. The Company does not anticipate that the adoption of this standard will have a material impact on its consolidated financial statements. The Company is evaluating the potential impact of this adoption on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-11, "Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures." ASU 2014-11 changes the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. ASU 2014-11 also requires new disclosures about transfers that are accounted for as sales in transactions that are economically similar to repurchase agreements and increased transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. This ASU is effective for the first interim or annual period beginning after December 15, 2014. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2016. The Company is evaluating the potential impact of this adoption on its consolidated financial statements.
	In April 2014, the FASB issued ASU No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 changes the criteria for disposals to qualify as discontinued operations and requires new disclosures about disposals of both discontinued operations and certain other disposals that do not meet the new definition. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2014. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists." ASU 2013-11 requires entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward when settlement in this manner is available under the tax law. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this standard did not have a significant effect on the Company's consolidated financial statements.
	In April 2013, the FASB issued ASU No. 2013-07, "Presentation of Financial Statements (Topic 205): Liquidation Basis of Accounting." The objective of ASU 2013-07 is to clarify when an entity should apply the liquidation basis of accounting. The update provides principles for the recognition and measurement of assets and liabilities and requirements for financial statements prepared using the liquidation basis of accounting. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this standard did not have an effect on the Company's consolidated financial statements.
	In March 2013, the FASB issued ASU No. 2013-05, “Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” This ASU addresses the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this standard did not have an effect on the Company's consolidated financial statements.
	In February 2013, the FASB, issued ASU No. 2013-04, “Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for which the Total Amount of the Obligation Is Fixed at the Reporting Date.” This ASU addresses the recognition, measurement, and disclosure of certain obligations resulting from joint and several arrangements including debt arrangements, other contractual obligations, and settled litigation and judicial rulings. The ASU is effective for public entities for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this standard did not have a significant effect on the Company's consolidated financial statements.
