PROBLEM TO BE SOLVED: To improve brake operability and suppress deterioration in cooling performance, regardless of a change in flow rate of cooling oil.SOLUTION: A brake device of a winch includes a wet multiple disk brake which has an inlet into which cooling oil passing between a plurality of friction plates is introduced and an outlet from which the cooling oil is discharged. The wet multiple disk brake includes: a pressing member for generating brake force by bringing the friction plates into pressure-contact with each other; a pressure-contact force adjustment device for adjusting the pressure-contact force of the friction plates each other by applying driving force to the pressing member; a working force control device for controlling force applied to the pressing member, which is force other than the driving force applied to the pressing member, so that force for increasing the pressure-contact force of the friction plates each other and force for decreasing the pressure-contact force are balanced.SELECTED DRAWING: Figure 2
【課題】冷却油の流量の変化に拘らず、ブレーキ操作性の向上を図るとともに冷却性能が低下することを抑制する。【解決手段】ウインチのブレーキ装置は、複数の摩擦板間を通過する冷却油が導入される入口および冷却油が排出される出口を有する湿式多板ブレーキを備えるウインチのブレーキ装置であって、湿式多板ブレーキは、摩擦板同士を圧接させてブレーキ力を発生させる押圧部材と、押圧部材に駆動力を作用させて摩擦板同士の圧接力を調整する圧接力調整装置と、押圧部材に作用する駆動力以外の力であって、摩擦板同士の圧接力を増加させる力と減少させる力とがバランスするように、押圧部材に作用する力を制御する作用力制御装置とを備える。【選択図】図2
