Steel bridge project of Jiaozi Peak Wind Farm in Panxian County, Guizhou Province

The project's bridge superstructure adopts a welded steel truss girder and rectangular hollow steel diagonal bracing design. The bridge is 32.0 meters long and 6.5 meters wide, with a structure including lower flanges, 8 webs, a top flange, and transverse stiffeners, forming a stable overall structure. The bridge has the capacity to bear a 130-ton heavy-duty trailer, spanning a valley, demonstrating its strong crossing ability. During the lifting process, due to geographical limitations, lifting operations could only be performed on one side. Therefore, the engineering team carefully planned and used a 300-ton truck crane in coordination with a 240-ton truck crane to ensure the smooth progress of the lifting work.
