作するようにしたことを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 equipped with a winch operation valve that controls pressure oil supply and discharge between a brake cylinder, a clutch cylinder, and a brake cylinder, the winch operation valve is a check valve, and a cam that pushes open the check valve is provided. A cam profile is formed on one side of the spout 1 to switch the pressure oil supply and discharge to the clutch cylinder and the brake cylinder in three modes, and a cam profile is formed on the other side of the spool to switch the pressure oil supply and discharge to the clutch cylinder and the brake cylinder. A hydraulically driven winch, characterized in that a cam profile is formed to switch between two types, and a winch operating valve is operated by appropriately selecting one of these two cam profiles.
