[0002] High-altitude protective equipment is an important tool to ensure the safety of workers working at heights. They play a vital role in various high-altitude work scenarios. A high-altitude fall arrester is a self-locking fall prevention device that can quickly complete self-locking through the internal ratchet and pawl at the moment the high-altitude worker falls, thereby avoiding the occurrence of falling accidents.
