The locking distance of the speed differential automatic control anti fall device is not related to the length of the steel wire rope

The speed difference automatic control fall arrester is currently a relatively professional high-altitude operation protection equipment. Both construction units and national regulatory departments are vigorously promoting this equipment. The reason for this is that in addition to the anti fall effect of the fall arrester, it is also inseparable from its ability to achieve self-locking function in an instant.

By comparing the speed difference automatic fall arrester with the high-altitude safety belt, we can find that the length of the high-altitude safety belt rope determines the distance that the high-altitude operator can descend after falling. The probability of a secondary collision accident during this period is very high, and if the calculation is incorrect, the safety belt rope worn will be greater than the distance between the high-altitude operator and the ground, making the use of the safety belt meaningless.

The speed difference self-control fall arrester is different. Regardless of the length of the steel wire rope of the fall arrester worn by high-altitude workers, once the worker slips and falls, the fall arrester can complete self-locking within 2 seconds, avoiding the worker from falling for a long time and a long distance, avoiding secondary injuries, and reducing impact force.
