Secondly, once the welded hanging walkway is installed, it is difficult to dismantle and move, which limits the flexibility of the construction site. Most importantly, this type of hanging walkway needs to be cut off after use, resulting in a waste of materials. On the other hand, the traditional hanging walkway has a simple structure and poor safety protection. Utility Model Content
