タグラインの油圧回路。 A hydraulic motor, which functions as a motor when winding the tag line rope and as a pump when unwinding the tag line rope, is directly connected to the tag line drum, and the hydraulic pump discharges to the suction side port of the hydraulic motor during the winding operation. A return pipe to the tank is connected to the discharge side port, and a relief valve for controlling the discharge pressure of the hydraulic pump is connected between both pipes, and the relief valve and the return pipe are connected to each other. A back pressure valve consisting of a check valve with a throttle is provided downstream from the connection point of the hydraulic tag line, and a bypass valve is provided between the discharge pipe and a return pipe downstream of the back pressure valve. Hydraulic circuit.
