切換回路。 Two hydraulic drive units are connected in parallel between the pressure line and the tank line via two 4-port, 3-position directional control valves, and a check valve is connected in parallel to each hydraulic drive unit. In addition, the oil inlets of the check valves are connected to each other, and one port of each directional control valve is connected to the tank line via a flow rate control valve, and each of the directional control valves is mechanically or electrically interlocked. At the center position of each directional control valve, connect the pressure line and the hydraulic drive part, connect either the straight or cross position, and when one of the straight or cross position is connected to the pressure line, the other A hydraulic stop switching circuit characterized by being disconnected from the pressure line.
