[0002] During the construction of the upper structure of the suspension bridge, catwalks are needed as construction channels and platforms to ensure the operation requirements of each sub-project. One set of catwalks is set up upstream and downstream, and a transverse channel needs to be set up between the two sets of catwalks at a certain interval to facilitate the passage of workers, that is, the transfer of materials and equipment, etc. At the same time, it can also improve the comfort of workers, which is crucial to improving the overall stability and wind resistance of the catwalk.

The catwalk line is a catenary, and there will be large differences in the installation angles at different transverse channels. It is more troublesome to process and manufacture transverse channels according to different angles. Utility Model Content
