| 摘要 | PURPOSE:To prevent the runaway of a bogie by movably providing two brake devices along a guide rail. CONSTITUTION:The ram 13d of a brake device 13B is protruded to restrict the shift between a guide rail 6 and the brake device 13, and a hydraulic jack 15 is driven to protrude a ram 15a. Then, a hydraulic unit 12 and the brake device 13A are moved in the B direction. Next, the ram 13d of the brake device 13B is retreated to release the coupling with the guide rail 6, and the ram 13d of the brake device 13A is protruded to restrict the shift between the guide rail 6 and the brake device 13A. Then, when the ram 15a of the hydraulic jack 15 is retreated, the brake device 13B and a bogie 7 are moved in the B direction together with mounted conduits 9. Accordingly, the conduits 9 are towed together with the bogie 7 and are installed. | ||||||
