Testing standards for locking performance of speed differential anti fall devices

The locking system composed of internal ratchet and pawl combination plays a decisive role in the safety of the use of the differential anti fall device. The locking system means that when a person or heavy object falls, the safety rope can automatically lock and stop falling. So, how should the locking performance of the differential anti fall device be tested?

When detecting the speed difference anti fall device, we should first hang the anti fall device on a fixed frame, hang a heavy object of about 80KG (simulating human body weight) with a rope from a high altitude, and then instantly release the rope to allow the heavy object to fall freely and impact downwards. This is the internal locking mechanism of the speed differential anti fall device, which will quickly and automatically lock to ensure the safety of the heavy object. After releasing the load, the internal locking mechanism will automatically resume use.

This is the performance test of the internal lock of the speed differential anti fall device. Only by checking the normal performance of the internal lock can the safety of the operation be ensured, and the safety of high-altitude operations can be fully guaranteed during high school operations. Regularly inspect the anti fall device to ensure its stable performance and protect the personal safety of high-altitude workers.
