Description

Technical Field

[0001] The utility model belongs to the technical field of safety ladder cages, and in particular relates to a safety ladder cage that can be quickly disassembled. Background Art

[0002] The safety ladder cage is a protective device made of steel material, usually composed of a ladder frame, a guard cage and a platform. The ladder frame is the main structure of the safety ladder cage and is used to support the entire equipment; the guard cage is a protective device made of wire mesh or steel plate, used to protect personnel and materials; the platform is a space for workers to stand and operate. The safety ladder cage has the characteristics of simple structure, easy installation, safe and reliable use, etc. It is one of the essential equipment for high-altitude operations.
