装置。A winch drum is fixedly attached to the shaft driven by the motor, and the first
The motor is configured to be able to rotate forward and reverse by supplying pressure oil from the pump through the hoisting side piping and the hoisting down side piping by operating a directional switching valve, A bypass pipe equipped with an unload valve is provided in between, and a low-pressure oil pipe from the second pump is connected to the lower-volume pipe located between the bypass pipe and the motor. A winch device for a hydraulic crane, characterized in that a pilot pipe taken out from a midway part is guided to the unload valve, and a directional switching valve is further provided at a required position of the low pressure oil pipe.
