[0002] The tower crane safety passage is a passage set up between the building and the tower crane so that the tower crane driver and other operators can safely and conveniently enter the tower crane horizontally from the building. At present, the traditional tower crane safety passage is assembled from steel pipe fasteners and fixed between the steel pipe scaffolding and the tower crane, which interferes with the force of the steel pipe scaffolding. It does not meet the requirements of the specifications and has certain safety hazards. It has become a high-probability deduction point in the inspection of various types of lifting equipment in recent years. In addition, the erection of the steel pipe assembled tower crane safety passage is usually carried out at high altitudes, which not only poses a greater operational risk, but also may cause fasteners to loosen, the load-bearing frame to be unstable, and the protective measures on both sides to be irregular during use, which poses a greater safety hazard.
