Can fall arresters and descent arresters be used interchangeably

Netizens often inquire about whether fall arresters can be used as a substitute for descent arresters? In fact, many people currently do not understand the essence of fall arresters. Some people mistakenly believe that fall arresters are used for high-altitude escape. In fact, fall arresters and descent arresters are two completely different devices. Below, Crown Airlines will take you to understand.

A descent device is a safety rescue device that allows people to slowly descend along a rope (belt). It can be installed in building windows, balconies, or flat roofs using specialized installation tools, and can also be installed on high-rise fire trucks to rescue victims in high-rise building fires. It drives the planetary gear reduction mechanism inside the main engine to operate and generate friction with the friction block inside the friction wheel hub through a descent rope, ensuring the safe descent of the user to the ground.

The anti fall device is not a slowly descending rescue device. It not only does not slowly descend, but also aims to prevent descent, that is, it can quickly complete self-locking at the moment of falling, avoiding the occurrence of falling accidents. It belongs to high-altitude operation equipment rather than rescue or self rescue equipment. When a falling accident occurs, it will quickly engage with the ratchet and pawl to brake, which is fundamentally different from the anti fall device. So the two are absolutely irreplaceable.
