[0002] As an important load-bearing member inside an arch bridge, the main function of the hanger is to transfer the load borne by the bridge deck to the arch rib. In a steel arch rib arch bridge, the hanger effectively transfers the weight of the bridge deck and other loads to the arch rib through its tension, and the arch rib then disperses the load to the pier or foundation. The top of the hanger needs to be precisely docked with the top of the steel arch rib to ensure the overall stability and safety of the structure. However, due to the high top of the steel arch rib, the environmental complexity of high-altitude operations, the accuracy requirements, and safety risks, the installation of the hanger is difficult.
