Description

Maintainable safety net picking system Technical Field The utility model relates to the technical field of building safety auxiliary equipment, in particular to a maintainable safety net picking system. Background With the acceleration of the urban process, the scale of the building engineering is continuously enlarged, and the height of the building is gradually increased. Aloft work becomes an integral part of building construction, however, the risk of falling aloft also increases. In order to ensure the life safety of constructors, the safety net is widely applied to construction sites as an important high-altitude anti-falling device. The traditional safety net picking often has the problem of difficult later maintenance in practical application.
