Problems solved by technology

[0004] However, mountaineering and rock climbers carry a variety of different types of climbing ropes for travel at the same time. If they choose to use them, it is not only troublesome to use, but also increases the load of the rock climbers, which is not conducive to the development of rock climbing and the safety protection of rock climbers.

Abstract

The application discloses a three-in-one power climbing rope and three-in-one power climbing rope equipment. The three-in-one power mountaineering rope includes nylon fiber rope core and nylon fiber sheath, the sliding rate of the sheath core is less than 0.1%, the static elongation rate is less than 8%, the first maximum elongation rate is less than 35%, the shrinkage rate is less than 5%, and the knotting coefficient The linear density is less than 1, and the linear density is less than 50 g / m. The diameter of the power climbing rope is 8.5-9.32 mm, and the diameter of the rope core is set at 7.2-8.3 mm. Power mountaineering rope combines the functions of traditional single rope, half rope and double rope. It is light in weight and high in strength. It can effectively absorb the impact force of the user and has a good buffering effect. In industrial operations, outdoor rescue and other fields with a fall coefficient greater than or equal to 0.3, it reduces the user's carrying load and effectively protects the user's personal safety.

Description

technical field [0001] The application belongs to the technical field of fiber ropes, and in particular relates to a three-in-one power mountaineering rope, a manufacturing method thereof, and three-in-one power mountaineering rope equipment. Background technique [0002] Rock climbing is a very popular sport. There are two main purposes of mountaineering and rock climbing equipment: one is to ensure the safety of the sport, and the other is to make climbers perform better. Among them, the power climbing rope is always the most important equipment in mountaineering. Power climbing ropes usually have high extensibility in order to reduce the impact on the descent of climbers and facilitate operation. They can be used as climbing ropes, and their drag loads can be buffered on huge walls, cliffs or caves. [0003] Power climbing ropes are divided into single rope, half rope and double rope. A single rope is a power climbing rope that can be used alone. It is used alone and i...
