Is it necessary for tower crane drivers to wear speed differential anti fall devices

In recent years, various high-altitude work sites such as construction sites have increased their supervision of high-altitude work safety. Speed differential fall arresters have been equipped for workers such as tower crane drivers and power workers who perform high-altitude work. Many workers who are already accustomed to safety belts and safety ropes believe that the existence of fall arresters is a burden, with repeated safety protection functions and safety belts, and increased load capacity. There is no need to wear an additional fall arrester.

The anti fall device is hung near the control room of the tower crane. When the tower crane driver climbs the tower crane in a normal state, the anti fall device is indeed a protective equipment without a sense of presence. As the height of the tower crane driver's climb increases, the steel wire rope of the anti fall device will sense the change in human weight and move upwards, reducing the load-bearing capacity of the steel wire rope. The steel wire rope will automatically retract inward. As long as the worker climbs carefully during the climb, the anti fall device will hardly work.

But when encountering light rain weather, the tower crane frame will become slippery. At this time, it is very important to wear a speed differential anti fall device. Once the tower crane driver accidentally slips and falls, the anti fall device can quickly lock the descent system within a few seconds, preventing the tower crane driver from falling to the ground. In this regard, the protective function of the anti fall device is far superior to safety belts, safety ropes and other protective systems.
