Use with ropes, ascenders, descenders, flat belts, etc. In the field of fire protection, safety hooks are mainly used to protect firefighters from falling during operation, and are also used in hauling systems. In the engineering field, the use of safety hooks is mainly to protect the safety of high-level builders. Both ends of the safety rope are connected to safety hooks, the safety hook at one end is hooked to the semicircle on the safety belt, and the safety hook at the other end is hooked to other fixed buildings (anchor points) after climbing. The parameters of the safety hook are working tension (WS) and blasting tension (BS). According to different standards and manufacturers, the parameters of the safety hook are also different.
The process flow for using snap hooks typically involves selecting the appropriate size and type of snap hook for the application; attaching the snap hook to the rope or cable; attaching the other end of the rope or cable to the anchor point or accessory; and using the spring-loaded gate to quickly and easily connect or disconnect the two items.
