Workers must wear speed differential anti fall devices when replacing billboards on the rooftop

There are particularly many strong winds in spring, with wind speeds around level 3. Strong winds are a high-risk period for falling objects from high altitudes. The raging winds not only break tree branches and topple vehicles, but also blow away or damage billboards on high-rise buildings. Once the billboard is scratched, it will affect the normal promotion of the business. Therefore, billboard installers need to climb several meters or tens of meters high to replace the billboard.

Replacing high-rise billboards at a height exceeding 2 meters is considered high-altitude work, which poses a risk of personnel and billboard falling. According to the national safety management regulations for high-altitude workers, high-altitude workers must wear speed differential fall arresters when replacing billboards.

This safety device is designed specifically for high-altitude workers. During operation, the upper hook of the protective device is hung on a fixed point above the worker, and the lower hook is connected to the safety belt worn by the worker. As the worker moves back and forth, the steel wire rope inside the protective device will freely expand and contract back and forth, which not only does not hinder the installation work of the worker, but also provides good protection.

The protective function of the speed differential anti fall device is usually in a suspended state. Once high-altitude workers experience rapid descent when replacing high-rise billboards, the protective function will be quickly activated to prevent personnel from continuing to fall, thereby protecting their personal safety.
