Steel box girder lifting project background:
The key project in the upper reaches of the Yangtze River—Jiangjin Baisha Yangtze River Bridge, the connecting line project spans the east and west banks of the Yangtze River. The total length of the project line is 3160 meters, the total length of the bridge is 1300 meters, and the main bridge has a main span of 590 meters. On the premise of ensuring epidemic prevention and control and construction safety, the project progress of the box girder suspension bridge is progressing in an orderly manner. The project adopts 4 sets of 400T and 4 sets of 260T lifting cylinders of Cairn special steel hinge line to lift and assemble the steel box girder of the suspension bridge. The travel problem for more than 200,000 people will also shorten the distance of material transportation between the north and south of the Yangtze River, and greatly reduce the transportation cost, which is of great significance to promoting the optimization of the transportation network in the southwest of Chongqing and even the upper reaches of the Yangtze River.
