What is the critical value for locking the steel wire rope of the speed differential anti fall device

The speed differential anti fall device is equipped with a dual locking system, flame retardant safety rope, and steel wire rope that is not easily worn off, with a high safety factor. Therefore, it has become a safety protection equipment in high-altitude operations, and there is no restriction on the height and position of the work point. As long as there is a stable suspension point, the anti fall device can ensure the safety protection effect.

The speed differential anti fall device is suspended at a fixed lifting point using a high hanging and low use method. As long as the worker is walking at a normal speed during normal operation, the steel wire rope inside the anti fall device will not be locked. As long as the length of the steel wire rope is within the range of the worker's movement and the worker is working in a relatively safe position, the steel wire rope will always maintain a free extension and contraction state and will not affect the worker's normal operation.

When the staff completes high-altitude operations, moves upwards or removes the hanging ring of the anti fall device, the safety rope will automatically retract into the interior of the cover. If during the operation, the staff wears a fall arrester and the descent speed of the steel wire rope exceeds 2 meters per second, the anti ratchet double basin braking system inside the fall arrester will control the steel wire rope to prevent it from continuing to fall.

So, the critical value of the double locking system inside the speed differential anti fall device for locking the steel wire rope is 2 meters per second.
