特徴とする油圧駆動ウィンチ。A winch drum driven by a hydraulic motor connected via a clutch, a clutch cylinder that engages the clutch, a brake that biases the winch drum in the braking direction with a spring, and releases the brake against the biasing force of the spring. In a hydraulically driven winch consisting of a brake cylinder that acts in the direction, a winch operating valve and a winch operating valve that control the supply and discharge of high-pressure oil stored in the pressure accumulator to the clutch cylinder and the brake cylinder, respectively, correspond to the operating position and the free fall position. A brake operation valve for controlling the supply and discharge of pressure oil in the hydraulic motor drive circuit, and an oil drain pipe connected to the brake operation valve is connected to the tank via the B port of the winch operation valve, and the B A hydraulically driven winch, characterized in that the port is closed when the winch operating valve is in a free lowering position.
