Abstract： The cable crane system has the advantages of long span and wide transportation space， and is the main hoisting equipment for the construction of suspension bridge of kilometer span bridge in mountainous area. The Kaizhou Lake Bridge， a long-span suspension bridge in Guizhou Province， has completed the transportation and installation of the steel truss girder by using the cable lifting system on one side. Through the discussion on the design and installation scheme of the cable crane system， the difficulties in the application of the cable crane are summarized， which provides a reference for its application in the construction of long-span suspension bridges.
