Based on the steel girder hoisting construction of Yangsi Port YangtzeRiver Bridge, the bearing capacity, applicability, safety and operation efficiency of 9000KN hydraulic hoisting cable-borne crane are studied. Considering the structural characteristics and parameters of the bridge, the hoisting methods of special beam segment and the construction cost and safety of double cable-borne cranes, the main parameters of the cable-borne crane of the bridge are determined. Then, the structure of cable-borne crane is checked by ANSYS. Finally, the cable-borne crane has been verified by experiment and applied in engineering. The results show that the structure of 9000KN hydraulic lifting cable-borne cranes is safe, reliable, excellent-performance, energy-saving and environmental. The whole structure of the cable-borne cranes adopts modular design and has strong versatility, which is conducive to installation, transportation and turnover utilization, and has brought better economic benefits to society.
