ーン等ウィンチの微速制御装置。The servo piston is equipped with a servo piston that changes the angle of the inclined plate of the variable pump, and the hydraulic pressure acting on the oil chambers at both ends of the servo piston changes in response to the pilot pressure of the control valve and the discharge pressure of the variable pump. A switching valve is connected to a regulator configured to minimize the discharge amount when it is open, and the one oil chamber of the 1 servo piston is connected to the tank via the switching valve, and a switching operation is performed on the switching valve.
A slow-speed control device for a winch such as a crane, which is characterized by a continuous actuator.
