回路。 A negative brake device includes a spring that applies force to the side that brakes a drum driven by a hydraulic motor, and a brake cylinder that operates to the side that releases the brake by supplying pressure oil, and a spring and pressure that applies force to the side that locks the drum. In a winch equipped with a lock device having a lock cylinder that operates on the side that releases the lock by oil supply, between a circuit that supplies pressure oil to the brake cylinder and a circuit that supplies pressure oil to the lock cylinder, A winch brake characterized in that a low pressure selection valve is provided to connect the circuit with lower hydraulic pressure of both circuits to the brake cylinder, and the spring force of the negative brake device is made larger than the spring force of the lock device. Tuning circuit between the device and the drum lock device.
