Application of speed difference anti fall device in large-span grid membrane installation project

When building large venues such as sports stadiums, shopping malls, museums, etc., it is necessary to install and construct a large grid above the building. When installing and welding the fixed grid structure, the staff need to climb up to a height of 52 meters. In front of the high-altitude work platform, they must first wear safety ropes, safety buckles, safety helmets, speed difference fall arresters, safety belts and other high-altitude work protection equipment.

The installation project of large-span grid membrane has the characteristics of complex construction environment, high operational difficulty, high quality requirements of the owner, and high difficulty in membrane structure construction. The function of hanging and installing anti fall devices is to prevent workers from falling from a high altitude, causing rapid body descent, scratching with surrounding building materials, or accidentally falling to the ground. Compared with safety belts and safety ropes, the safety protection level for high-altitude falls is further improved.

Installing large-span grid membrane above large buildings is a long-term, arduous, and complex system engineering. Like other safety protection equipment, speed differential anti fall devices are the prerequisite and guarantee for the safety work of high-altitude workers, playing a crucial role.
