The high falling accidents are caused by high operation, so that the high falling accidents can be simply classified according to the classification form of the high operation. According to the rule of "classification of high-altitude operations" (GB/T3608-2008), operations performed at a high altitude where a height reference plane falls above 2m (including 2 m) are all called high-altitude operations. The conventional safety belt rope is generally 1.5-2 m long, the movable range is small, and the safety belt rope needs to be unhooked and hooked for many times during large-scale operation. The picking and hanging process has a great potential safety hazard. At the moment, the artificial drawing is convenient for the construction production without corresponding protection after unhooking, the safety accident happens at one time-! If the length of the safety rope is simply increased, the impact displacement is larger, the impact force is stronger, and the impact force generated by the safety rope is about 20Kn according to the related test data of 5 meters, which is far beyond the bearing capacity of a common person.
The traditional three-point type or five-point type safety belt has the advantages that the rope length of the traditional safety belt is generally 1.5-2 m, the movable range is small, the hook and the hook are required to be unhooked for many times during large-scale operation, a large potential safety hazard exists in the unhooking and hanging process, and sometimes workers can put into construction production without corresponding protection after unhooking for the convenience of drawing, so that serious safety accidents are easily caused.
