Design and application of 9000KN hydraulic lifting cable-borne crane for suspension bridge steel girder erection

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.
