[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to enable vehicles, pedestrians, etc. to pass smoothly. Bridges can be divided into beam bridges, arch bridges, cable-stayed bridges, and suspension bridges according to their structures.

[0003] A suspension bridge is a bridge with cables or chains that bear tension as its main load-bearing components. It is composed of cables, pylons, anchors, hangers, bridge deck systems and other parts. The cables can play a load-bearing role during use. Since they are in a load-bearing environment across rivers, lakes and seas, they bear dynamic and static loads and are exposed to wind, rain, humidity and polluted air for a long time. The cable body and anchor structure are susceptible to corrosion damage. Before installing the bridge cables, a strength testing device is required to check the strength of the cables.
