How to use rock climbing descent
For excellent rock climbers, the upper and lower limb strengths are coordinated. For beginners or athletes who are not skilled enough, upper body strength is more important. When climbing, it is often the upper limb pull-up. The lower limbs press and lift the legs to move the body. What safety equipment is needed for climbing? Rock movement has certain dangers, so the equipment for safety equipment and rock climbing is part of the rock climbing movement, which is the safety guarantee for climbers, especially in the climbing of natural rock walls. The choice of climbing shoes is generally 2 yards smaller than the usual shoes, but the beginners choose the same shoe size as the peace shoes when they choose climbing shoes, so that they can adapt to the feeling of climbing shoes more quickly. In the next half year, they may find that the climbing shoes are big and need to change the rock climbing again. Shoes; in addition, climbing personal equipment refers to seat belts, descenders, safety locks, rope sets, safety helmets, rock climbing shoes, magnesium powder and powder bags, etc. Let's take a closer look at how to use rock climbing descenders?First, eight word loop descender use:The eight-word loop descender is a commonly used descender that increases the friction by controlling the 8 points formed by the rope in the 8-word loop to control the descending speed. When retracting the eight-character ring, be sure to handle it gently. If the ring is cracked, even if it is small, it should be stopped immediately.Bind the safety rope to the 8-word ring lowering device, pick up the rope at the fixed point (remaining a distance of about 1.5 meters from the fixed point), then fold the rope, insert it from the large ring of the 8-ring ring, and put it in the small ring. Upper, then connect the small ring of the 8-word ring lowerer to the safety buckle on the safety belt.When you wear a non-slip glove to lower it, be sure to note that when using the 8-word loop lowering device, one hand should grasp the rope at the upper end of the 8-ring ring lowering device, and the other hand grasp the rope below the 8-word ring. By gripping, slow down the rope at the lower end of the 8-word loop lowering device for safe lowering.The splayed ring does not require a particularly high diameter for the rope used, and the scope of application is relatively large. For example, the large ring of the A-shaped eight-ring ring can fit the rope of 8.3mm or more. In turn, the small ring of the A-type is suitable for the rope of 8.3mm or less.The correct entry can prevent the 8-word ring from falling, it is very likely to fall in extreme circumstances, and it may be delayed because of your failure to check back or your more serious consequences!However, the 8-word ring has a big problem, especially when it is used in an indoor climbing hall. Because of its braking principle, the protective rope is wound through the 8-word ring. After repeated use, the rope will be twisted into a mess. Hard to clean up.Second, the use of ATC descenderATC is a descender that uses * as a wide range of protectors in addition to the "8" subring in recent years. It is much simpler than the mechanical protector structure, and the operation is as simple as the "8" ring. However, compared with the "8" ring, the advantage of the big one is that the rope is not prone to deformation after being locked, causing curling and twisting. In addition, the ATC relies on the brake end to press down to generate the rope type and increase the friction. Therefore, the ATC moves into the brake end and the climbing end. Pay attention to the rope direction required by the legend on the protector when loading the rope.ATC requires stricter diameters for the ropes used than the "8" ring, typically 8.3mm-12mm, such as E/F/H. But if the ATC needs to match a small diameter rope, then choose a small diameter ATC. For example, G and H, the diameter of G is 7.5 mm - 8.2 mm, and the diameter of H is 8.1 mm - 11 mm.Third, mechanical brake type descenderThe mechanical brake type protector is much more complicated to operate than the "8" ring type protector and the ATC type protector. In particular, there are very strict regulations on the loading rope, and if it is wrong, the fatal danger can occur directly.The mechanical brake type protector is also very different in comparison with the "8" sub-ring type and the ATC type protector. They are generally only used for descent (single rope) and top rope protection (single rope). Its * outstanding advantage is that it can be self-locking and can be controlled like Stop by controlling the free rope end by hand to control the descent speed.The adventure movement has its inherent dangers. It is the responsibility of every explorer to use the equipment correctly and use the technology reasonably. When the equipment is used incorrectly, the consequences are not related to this article.Even with a wealth of expedition experience and the use of equipment in full accordance with the correct operating procedures, the potential for accidents caused by the natural environment and human factors cannot be avoided. This is what every explorer should know before engaging in the sport.
