What is the sliding distance of the self-locking differential

The maintenance of cables and wires at a height of 100 meters, the cleaning and painting of windows and exterior walls of buildings at a height of 100 meters, and the maintenance of large mechanical equipment at a height of 100 meters are all essential for high-altitude operations. The use and protection of self-locking differential devices are indispensable for them. The existence of differential devices is a life-saving tool and a reliable protective equipment that can be entrusted to life. When high-altitude workers experience rapid falling reactions during high-altitude operations, the differential devices can quickly respond, lock the descent system, and the steel wire rope can firmly grasp the high-altitude workers in mid air, preventing them from falling accidents.

Friends familiar with self-locking differential devices know that at the moment of a high-altitude fall accident involving a person wearing a differential device, the differential device will have a brief reaction time and short distance buffering before automatically locking the descent system. Within this time range of less than one minute, the steel wire rope of the differential device, also known as the safety rope, will continue to extend downward with the fall of the human body. As for this sliding distance, the manufacturer's data is no more than 0.2 meters, and the impact force is less than 2949N.

0.2 meters, also known as 20 centimeters, is equivalent to the length of a short ruler. Within this distance range, if there are no obstacles around the descending personnel, they will be safe and sound. However, if there are obstacles, they may collide with the human body and cause certain injuries.

So wearing a self-locking differential does not mean putting on a safety jacket. Before working, the surrounding environment should also be checked.
