Description

Technical Field

[0001] This utility model relates to the field of ladder cages, specifically a safe and reliable ladder cage. Background Technology

[0002] Ladder cages are prefabricated light steel structure ladders, consisting of handrails, a cage frame, and connectors. They are suitable for all buildings requiring maintenance and safety ladders and can be used in building maintenance and construction, providing safety protection. Currently, most ladder cages on the market have the cage frame surrounded by several railings, allowing users to work directly on the operating platform. During use, the cage frame is usually connected to the ground with fasteners to determine the installation position of the ladder cage. Over time, because users need to walk back and forth on the operating platform repeatedly, and the bottom of the cage frame is often rigidly connected to the ground, wear and breakage often occur, causing the entire cage frame to tilt. The ladder cage is prone to tilting and swaying during use, resulting in poor stability and low safety, which hinders its widespread use. Utility Model Content
