PROBLEM TO BE SOLVED: To save labors for maintenance by easily adjusting elongation of main cables 21 of an elevator for connecting bridge suspending two cars 12, 112 by a series of main cables 21. SOLUTION: A first car 12 and a second car 112 installed to a first bridge pier 11 and a second bridge pier 111 supporting a connecting bridge 4, and an adjusting weight 24 are suspended by a series of main cables 21. A take-up machine 22 and a braking machine 23 are interposed between both of the cars 12, 112 so as to wrap the main cables 21. Under a condition that the adjusting weight 24 is locked to a fixing part 11, the take-up machine 22 is actuated, and the cars 12, 112 are elevated in directions opposite to each other. Thereafter, the braking machine 23 is actuated to hold the cars 12, 112 at a predetermined position. When the main cables 21 are elongated, the lock of the adjusting weight 24 is released and lowered under a condition that the braking machine 23 is actuated. Length of the main cable 21 at a portion for suspending the adjusting weight 24, so as to keep the length of the main cable 21 at the portion for suspending both of the cars 12 and 112 within a predetermined range. As a result, even when the main cable is elongated, there is no need of cutting and shortening the main cable, so as to save labors of maintenance. COPYRIGHT: (C)2005,JPO&NCIPI
