Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a device for multiply operating a first hydraulic cylinder and a second hydraulic cylinder. SOLUTION: Each cylinder has a head side port and a rod side port. This device includes a tank, a pump connected with the tank and a control valve. The control valve has an inlet port connected with the pump, an outlet port connected with the tank and first and second control ports. Each of the devices has at least a port connected with at least a corresponding one of the first and second ports and at least other port connected with a corresponding one of the head side port and the rod side port of the first and second hydraulic cylinders and includes at least two two-position valves operatable so as to selectively change over and flow hydraulic fluid to one of the first and second hydraulic cylinders from each of the first and second control ports of the control valve.
