Differential speed device: an essential protective device for construction operations on tower cranes

An accident occurred in Suzhou City, Anhui Province, where a worker fell from a tower crane. Both workers were seriously injured and were sent to the hospital for treatment. The cause of the accident was that three workers were installing tower crane cables, but during the construction process, two workers slipped and fell, resulting in an accident.

After confirmation, these three workers only wore safety helmets during construction on the tower crane and did not wear any other safety protection measures. If they wear a differential before construction, the differential can lock in time when they fall, preventing them from continuing to fall and avoiding an accident.

So, I would like to remind everyone again that when engaging in high-altitude operations, it is necessary to wear a differential gear, which can save lives in a timely manner in times of danger.
