PURPOSE:To provide a simplified tubing and functional performance by constructing the tubing in such a manner that the hydraulic pressure is supplied from the hydraulic unit for driving each cylinder and solenoid valve unit of the trolley for carrying objects to the trolley transfer device. CONSTITUTION:The hydraulic pressure is supplied from the ports A, B of a hydraulic unit 37 to the ports E1, E2 of a solenoid valve unit 38, and from ports C, D to the ports S1, S2 of a solenoid valve unit 39 respectively. The ports F1, F2; H1, H2; J1, J2; L1, L2; and P1, P2 of the solenoid valve unit 38 are respectively connected to the double motion hydraulic cylinder 12 for moving the transfer device 9 in the fore-to-aft direction, rotor cylinder 20A 20B for driving the objects stopper pin and clamp cylinders 23A1 to 23B2 to supply the hydraulic pressure. Likewise, the ports T1, T2; W1, W2; and Y1, Y2 of the solenoid valve unit 39 are connected to the cylinders 7a-7d for driving the centering cone and the cylinders 14A, 14B for moving top plates 15A, 15B to supply the hydraulic pressure. By this constitution, the hydraulic tubing can be simplified.
