Developing and Research on Equipments Specialized in Construction of Runyang Suspension Bridge

The deck erection gantry is a specialized equipment for erection of suspension bridge deck segments,it has mainly two forms of winch type and hydraulic lifting type. By analysing service conditions and performance index of the gantry and investigating the same kind of deck erection gantries at home and abroad, a new-type of full hydraulic, modular, and concentrated controlled gantry with wide range of application is designed and developed in light of actual conditions of steel box girder erection in Runyang Suspension Bridge.
