The 1300t bridge crane is the largest bridge crane with single lifting point in the world. It innovatively puts forward the overall scheme of super large bridge which carries the bridge frame with three main beams and hinged ends, the main and auxiliary trolleys running independently, and the steel wire rope multi-layer folding line winding. Developed the super large bridge machine digital prototype.The trajectory mathematical model of the winding guide ring is established. Overcome the seismic analysis and optimization of large critical load bridge; Breakthroughs in the integration of design structure and process manufacturing of large key components such as large beams. The intelligent control system of super large crane has been developed, which has improved the automation, information level, safety, reliability and maintenance convenience of the whole machine. Through the organic integration of traditional design methods and modern design methods, the 1300t single-point bridge crane for the main building of the world's largest hydropower station with large load capacity, small weight, compact structure, stable operation, safety and reliability has been successfully developed, filling the gaps at home and abroad, and providing equipment support for the smooth construction of the national key projects Baihetan and Wudongde Hydropower Station. It has created a new way for the high-end development of super large bridge cranes.
