る油圧駆動ウィンチ。[Claims for Utility Model Registration] Brake member 1 biased in the braking direction by spring 21
In a hydraulically driven winch, the winch drum 8 □ is equipped with a winch drum 8 □ and a first brake cylinder 18 that receives hydraulic pressure to act on the brake member 16 in the releasing direction against the biasing direction of the spring 21 . A mask cylinder 29 is actuated by the pedal 28, a second brake cylinder 30 receives hydraulic pressure from the master cylinder 29 and acts on the brake member 16 in the braking direction, and a first brake cylinder 30 operates. ' The mask cylinder 29 is interposed in the supply circuit to the rake cylinder 18 and is normally energized in a position communicating with the tank.
A hydraulically driven winch comprising a brake control valve 3-4 which is switched to a position communicating with a hydraulic pressure source when supplied with hydraulic pressure.
