Function of fall arrester in aerial work

The "double locking device" structure adopted by the fall arrester for high-altitude operation has the advantages of stable locking, high safety factor and good reliability, and can effectively solve the accidents caused by hitting other objects due to excessive falling and swinging range of inclined operation. The fall arrester control system adopts special steel and special treatment, which is light and impact resistant. The shell adopts aluminum alloy, which is light and non-aging. The safety rope shall be aviation steel wire rope. The sling and safety belt are flame retardant and resistant to high temperature of 200 ℃. When using differential fall arrester, it must be protected according to gb24544-2009 specification for automatic fall protection differential fall arrester. When using differential fall arrester, the principle of hanging high and using low must be adhered to. Hanging high and using low does not mean that people working at heights must hang fall arrestors at heights. The high hanging of the anti falling device can be realized by the hanging rod of the anti falling device.

The fall protection device for high-altitude operation is mainly composed of fall arrester, track, direction converter, connecting rope, fixed connection and other main components. Each component is indispensable. They form a complete individual. When workers encounter stepping on the air, they quickly make a series of reactions to protect the safety of high-altitude operation of workers. Before fixing the fall arrester, we must carefully check the safety of the fixed points. Some fixed points are located in the outdoor environment and are exposed to wind, rain and sun all year round, resulting in a sharp decline in their performance and the fragility of hard metal, so we should pay attention to these. The place where the fall arrester is fixed must be a solid object, and it is certain that it is more than 6 times that of the suspended object. When fixing, just pass the nylon sling rope over the solid blunt side structure above, and then hang the iron hook on the nylon rope on the "n" ring.

The operator can use the connecting rope to connect the safety belt and speed differential fall arrester on his body. When the second gear high-altitude operation step is empty at any position of the pole and tower in the taxiway in the guide rail through the fall arrester, the operator can be firmly locked on the track to prevent casualties caused by falling from the air.
