Description

Technical Field

[0001] The utility model belongs to the technical field of the structural design of safety anti-falling devices, and particularly relates to a falling prevention device for electric power construction. Background Art

[0002] Anti-falling at high altitudes in the State Grid is a very important task. Because in electric power construction, falling from high altitudes is a very serious safety problem. The occurrence of major accidents will not only cause casualties, but also have a serious impact on power supply. Therefore, anti-falling work at high altitudes in the State Grid must be highly emphasized and strict preventive measures must be taken. It has been widely applied and practiced in China's electric power construction and has also achieved remarkable results.
