| Abstract: | This paper deals with the construction of lifting and installation of the north main cable saddles of Wuhan Yangluo Changjiang River Highway Bridge by the lifting support made up of the main girder and hoisting trolley of overhead launching gantry. The support is structurally stable, easy to be operational, time-saving, therefore providing an alternative for installation of the cable saddles. Moreover, the utilization of the support also improves the force conditions of the tower top portals for erection of superstructure of suspension bridge and is helpful to the com- parison and selection of the tower top portals. |
