る杭打機の油圧回路。 In a hydraulic circuit in which the supply and discharge pipes connected to the inlet and outlet sides of the winch motor are connected to the pump via a control valve, there is a part of the supply and discharge pipe that serves as the pressure oil supply side during auger press-fitting work, and is directed toward the winch motor side. At the same time, a pilot check valve is provided in the supply side supply/discharge pipe at a position between the pilot check valve and the winch motor, and the other end of the control pipe, one end of which leads to the tank, is connected to a position between the pilot check valve and the winch motor. A pressure oil supply pipe from another small pump is connected, and a pilot relief valve is provided at a position between the pressure oil supply pipe connection part of the control pipe and the tank, and the relief pressure of the pilot relief valve is further adjusted. A hydraulic circuit for a pile driver, characterized in that it is equipped with a remote control valve.
