The significant effect of adopting the utility model is that the top of the tower column is located in the tower top accommodation space, and the working platform is installed and limited by the two supporting components and the two lateral anti-slip frames, so that the working platform is not easy to move, and the support stability is better.

[0004] In the above technology, although the anti-drop frame is used to limit the support assembly to prevent the working platform from moving easily and make its support more stable, the installation of the cable-stayed bridge requires a lot of length and the cable-stayed cables with different inclined angles need to be assisted by the tower top during installation to help workers ensure the safety of installation at high altitudes. The stress area of ​​the tower top bracket cannot fully guarantee the construction safety by relying on two support assemblies, and the stability of the construction platform is poor.
