Background technique

With the continuous popularity of outdoor mountaineering, ascenders are increasingly used as important self-protection equipment for mountaineering and caving enthusiasts in various countries when passing through dangerous areas. The ascender is mainly used for climbing on steep terrain. It is used in conjunction with seat belts and main ropes when caving ascends or protects. In addition, the ascender is also an important part of the hauling system, usually replacing the "claw rope" (also known as "chicken claw rope", namely "Prusik"). It is the core device used by fire and rescue agencies to pull heavy objects when dealing with accidents, and it acts as a "repeated lifting" device in the lifting system.

At present, ascenders are divided into three types: hand-held ascenders, chest ascenders and foot ascenders, among which hand ascenders are further divided into left-hand and right-hand. Use the left and right hand ascenders. Each ascender should have its own rope ladder. When the left hand rises, the rope ladder will drive the left foot to lift. After the left hand is in place, start to pull with the left hand and step on the left foot to make the body rise. After the left foot is stable, start the right hand. the same action. Climb the body upwards by moving left and right in sequence.

In the existing hand-held ascender, a rope wrench is pivotally connected to one end of a handle, and a pulley block is fixedly connected to the other end. Since the design of the fixed part of the handle is the same as that of the pivot part, it cannot be configured and assembled with other pulley blocks, so that the ascender cannot be used to replace the required pulley block according to the user's preference or expertise.
