に構成したことを特徴とするアウトリガ回路。 In construction machinery, work vehicles, etc., in which outriggers rotatably mounted on the left and right sides of the vehicle body are extended by hydraulic cylinders, the rod-side oil chambers of the left and right hydraulic cylinders are controlled by pilot-operated check valves. first and second solenoid valves are arranged in an oil passage that communicates the hydraulic cylinder and the hydraulic source so that pressure oil from the hydraulic source is connected to the first solenoid valve when the first solenoid valve is switched. 2 solenoid valves or the rod side oil chambers of the left and right hydraulic cylinders, and on the other hand, switches are provided in the electric circuit for raising and lowering the left outrigger and raising and lowering the right outrigger, and the switches are selected. An outrigger circuit characterized in that the excitation pattern of a solenoid for a solenoid valve is set by operation, and the operation of left and right hydraulic cylinders is controlled.
