装置。 A first cylinder and a second cylinder, which are arranged with their piston rods facing each other in a straight line, are connected to a hydraulic power source and a tank via a three-position solenoid switching valve, and the solenoid switching valve is connected to one extreme position. When switching to the forward position, the second cylinder is set to neutral and the first cylinder is set to the forward limit, and when the electromagnetic switching valve is switched to the normal position, the first cylinder is set to neutral and the second cylinder is set to the forward limit. A three-position control device, characterized in that when the second position is determined by the first cylinder and the electromagnetic switching valve is switched to the other extreme position, the third position is determined by the backward limit of the first cylinder.
