Fall arresters and descent arresters are two completely different types of high-altitude equipment

Many people cannot distinguish between a descent control device and an anti fall device, and often confuse the two. In fact, there are significant differences in their appearance and function. Below, Crown Airlines will analyze these two products in detail.

Different job responsibilities: The main job of the descent device is to slowly descend and escape, using safety hooks or auxiliary ropes to fix it to emergency windows in buildings or temporarily hanging it on fixed objects such as windows, balconies, or building ceilings to slowly descend and escape. The main work content of the anti fall device is high-altitude operation, which is fixed to a sturdy point with a hook to avoid falling accidents.

Different working methods: The key of the descent device is to slowly descend, which drives the planetary gear reduction mechanism inside the main engine through the descent rope to operate and generate friction with the friction block inside the friction hub, ensuring the safe descent of the user to the ground. The focus of the anti fall device is on preventing falls, which achieves instantaneous braking through the engagement and self-locking of the internal ratchet and pawl under high-speed operation, terminating the continued fall of the person who has slipped.

In layman's terms, descent arresters are used to safely reach the ground for evacuees, while fall arresters are used to prevent high-altitude workers from falling to the ground. Although both are high-altitude equipment, the differences are still quite obvious. Now everyone should be more familiar with these two types of equipment.
