Mountaineering equipment is generally divided into main rope and auxiliary rope. Generally, the length of the main rope is about 60-100 meters, the diameter is about 10 mm, and the weight requirement per meter is about 0.08 kg. The tensile strength of this climbing rope is average. The requirement must not be less than 1800 kg. Mountaineering ropes were generally made of jute in the past, but now they have been switched to nylon fibers as raw materials. There is also the main rope with a diameter of 8–9 mm. This rope weighs 0.06 kg per meter and has a tensile strength of not less than 1600 kg. It is mainly used for climbing steep and dangerous rock walls.
So far, climbing ropes and carabiners are still essential equipment in mountaineering. The selection of climbing ropes, climbing, descending and protection, and other mountaineering techniques are generally carried out centered on the climbing ropes. Iron locks, safety belts, and mountaineering items can only play a role when linked with climbing ropes and carabiners.
Early climbing ropes were generally made of cotton and then developed to use hemp.
Modern climbing ropes are designed and produced according to the requirements of modern mountaineering. All climbing ropes are made of mesh ropes with a layer of the outer net on the outside of several strands of woven ropes instead of ordinary nylon ropes. According to the different requirements of use, there are mainly two types of wear resistance and friction, and the outer net of the climbing rope is also divided into single-woven or double-woven. Generally speaking, the climbing rope with a single-woven outer net has less friction and is more wear-resistant. There are various colors of climbing ropes. Generally speaking, the ropes used by different members of the same mountaineering team are best separated in color so as not to lose things during technical operations.
The average climber always thinks that the pulling force of the climbing rope is an essential technical parameter. Connect the number of falls (UIAAFULL) to these parameters.
knotting method
First of all, I will introduce a method that is usually used. This is a method of dividing the rope into left and right sides, and the rope can be tied without knots. When dividing the rope, the length of one time is preferably equal to the maximum distance between the hands. If it is too short, the tied rope may become too large. It can also be placed on the wrist when one hand cannot handle it when tying up.
Other knotting methods of climbing ropes
1.Backed-upSquareknot, in the case of no carabiner, this method is the best choice for connecting two ropes because it is easier to untie after bearing weight.
2. Doublefisherman’sknot, the most suitable for the carabiner to connect the rope loop (runner) or the rope that is permanently placed (not often untwisted) because it is more difficult to untie after bearing weight.
3. Clovehitch double tack, easy to tie and adjust. This is more suitable for the erection of carabiner fixing points.
4. Gargaknot is a knot that can limit the rope’s movement only in one direction. The carabiner is suitable for towing some not too heavy objects, significantly when no one can help you tow.
5. Munterhitch, this knot can be used for security, especially when you lose security equipment or don’t have equipment. It is best not to use the Italian half knot to descend; otherwise, the rope will be easily tangled. Italian half knot + a rope loop (runner) + a carabiner, equivalent to a simple sling and descender. It is the best necessary equipment for a climber every time you climb a mountain. Sometimes you can prepare it yourself. Sometimes you can help other people.
