Speed difference self-control anti fall device combined with safety belt for safety protection during high-altitude operations

The lower hook of the speed differential automatic fall arrester cannot directly contact the human body, so it must be used in conjunction with a safety belt to form a personal fall protection system. This combination is of crucial importance for workplace safety and overall fall protection plans. It can be seen that the implementation of the locking system function of fall arresters cannot be achieved without the support of seat belts.

The key to the direct contact of seat belts with the human body lies in the characteristics of their manufacturing materials and components. Among them, the safety rope made of nylon material and the safety belt body made of polyester or polypropylene material have strong firmness. They can not only firmly restrain the human torso, but also disperse the impact force generated during a fall to multiple parts of the human body such as the chest and shoulders, effectively reducing harm to the human body.

However, the limited length of seat belts makes it difficult to meet the need for human movement back and forth during high-altitude operations. If used in combination with ordinary safety ropes, it is easy to cause collision accidents; When used in conjunction with a speed differential automatic fall arrester with a locking system, it can not only not affect normal operation, but also significantly improve the overall safety factor of protection.
