Abstract: The main part of Yinghe Bridge on Xiangyang Road of Fuyang is a composite system bridge with three-span through beam and arch bridge,the construction scheme of segmental assembling with cross-bridge gantry crane is used for the main bridge.According to the construction scheme and the main bridge structure,two portal cranes are used as the lift-ing equipment separately with 15 m rise height,45 m gauge and 40 m lifting height,45 m gauge.Combined with the actual situation of the main bridge’s complex terrain,this paper made a research on the key installation technology of large gauge gantry crane,and introduced the rail bracket design,technological process of assembling outriggers and main girders by the large truck crane and notice items of the installation.Practice had proved that the installation technology was feasible and could provide a reference for similar portal crane installation.
