| description | To provide a cooling mechanism that can both eliminate the need for a dedicated hydraulic pump to cool a wet clutch and control the pressure increase in the wet clutch caused by the oil cooler, and a crane equipped with the cooling mechanism.SOLUTION: A cooling mechanism for a crane 100 has a hydraulic pump 21 that discharges hydraulic oil, a hydraulic motor 23 that operates upon receiving the hydraulic oil supply, a winch drum 11 driven by the hydraulic motor 23, a wet clutch 6 that switches between a connected state in which the power of the hydraulic motor 23 is transmitted to the winch drum 11 and a disconnected state in which the power transmission is interrupted, an oil cooler 13 for cooling the hydraulic oil, and a cooling target switching valve 15 that can change between a clutch supply state that allows the hydraulic oil to be supplied to the wet clutch 6 and a cooler supply state that allows the hydraulic oil to be supplied to the oil cooler 13.SELECTED DRAWING: Figure 2
【課題】湿式クラッチを冷却するための専用の油圧ポンプを省くことと、オイルクーラに起因する湿式クラッチ内の圧力上昇を抑制することと、を両立できる冷却機構及びこれを備えたクレーンを提供する。【解決手段】クレーン１００のための冷却機構は、作動油を吐出する油圧ポンプ２１と、作動油の供給を受けて作動する油圧モータ２３と、油圧モータ２３により駆動されるウインチドラム１１と、ウインチドラム１１に対して油圧モータ２３の動力が伝達される接続状態と動力の伝達が遮断される遮断状態とを切り替える湿式クラッチ６と、作動油を冷却するためのオイルクーラ１３と、作動油が湿式クラッチ６に供給されることを許容するクラッチ供給状態と作動油がオイルクーラ１３に供給されることを許容するクーラ供給状態との間で変わることが可能な冷却対象切替弁１５と、を備える。【選択図】図２ |
