| Abstract: | Main cable saddle of Right Branch Main Bridge in Jiangxin Island of Nanjing Yangtze River Tunnel Project has the design weight of 130 t, hoisting height over 80 m. For such ultra-mega-hoisting components, in order to save cost, we cut the saddle into 3 blocks, each block no more than 40 t. We successfully completed the main cable saddle hoisting job by designing and lifting scientifically the steel frame and making the construction program rational. |
