cat-walk is the most important passage and place for working at high altitude in the construction of suspension bridge superstructure, and its profile, structural safety and anti-wind stability are related to the quality, progress and work safety of all main work sections in the construction of the whole superstructure. The load bearing cables are the main load-bearing components in cat-walk structure, usually made of twisted steel wires. In the construction of superstructure of Taizhou Bridge, for the cat-walk load bearing cable wire ropes for repeated use, complete inspection plan is formulated with reference to relevant specification in China, with good effect in ensuring the structural safety of constructing cat-walk and lowering construction cost, and this is of positive significance to the repeated use of cat-walk wire ropes in bridge construction in China.
