Rock climbing, which used to be regarded as an expert activity, is now loved by many people, regardless of gender, age and age. This is because people gradually realize that rock climbing is by no means a dangerous activity as long as they have basic skills. But among the basic techniques of rock climbing, knots account for the largest proportion. The basic method of rock climbing is to unite members to ensure each other's safety and continue climbing; In other words, when a person is climbing, other members can ensure that they are prevented from falling. Its safety is more secure than the way of climbing. But if you want to use this skill flexibly, you must learn all kinds of knots, and at the same time, you must correctly understand the operation method of climbing rope and really master your own movements. What's more, a slight negligence in rock climbing will cause irreparable tragedy, so the operation of knots must be cautious and correct.
Rock climbing protection measures
The person in charge of safety should cooperate with the team leader to recover the climbing rope. In case of accidental slip, the guarantor must control and prevent the climbing rope from slipping. Because climbers take protective measures while keeping a proper distance, as long as the main protective rope is not loose, people will not fall after controlling the climbing rope action; At the same time, the person in charge of safety must also do a good job of self-safety protection for himself.
1. Tie the rope to the safety officer's belt.
The climbing rope tied to the safety belt can be completed by using one of double splayed knots, human knots or deformed human knots. The double eight-character knot is solid, so don't worry about whether it will be loose. The disadvantage is that it is not easy to untie. On the other hand, although the knot does not have this shortcoming, it may loosen automatically if it is not handled at last. Judging from these places, the deformed human knot will not loosen, and it is easy to disassemble, which has been loved by many climbers recently. No matter what kind of knot you use, never forget to check the knot again before climbing.
Double splayed knot
Tie a splayed knot in the middle of the rope, then bypass the waist and thread the end of the rope through the knot in the opposite direction.
Weighing knot
After the knot is tight, tie a half knot and fix it.
Deformation is called human knot.
First, weigh the knot, then wind the rope head around the rope loop again and tighten it.
Make a rope loop
Tie the two ends of a rope together to form a rope loop, which can be divided into rope loop and belt loop. Although this kind of thing is sold in the market, with a little hands, you can make ropes or belts around you into ropes and belts of different sizes. When you make it yourself, you can make a loop with water knots, while the rope loop is made of fishermen's knots.
Rope ring is an indispensable thing in the protective measures to create safe support points for rock climbing; In addition, it can also play a role in unexpected situations, so it is best to make more preparations in advance in case of emergency.
3. Take measures to ensure that
When a climber accidentally falls, the technique of controlling it and stopping it from falling is called ensuring measures. The method of determining the leader is different from that of determining the second climber. In addition, the self-rescue measures to avoid falling rocks and the connection guarantee set by the team leader to shorten the falling distance as much as possible are quite distinctive methods. Make sure you only need to use two kinds of knots, double knots and knots, but you need more organized rope climbing skills, so you must really learn them.
Create a support point
Ensure that the climber's support point or rescue measures can be made of climbing nails, trunks or screws. The most common method is to tie the rope to the bracket with knots. If the supporting points come from more than two places, the rope loop must be made to bear the same force on each supporting point.
Self-help measures
Members must take self-help measures when ensuring work or climbing to the top. The method is to tie the climbing rope of your seat belt to the climbing hoop with a double knot.
The guarantee measures are implemented on the leaders.
Tie the climbing rope through the figure-eight ring and the hook ring at the waist, and send it out with the body as the support point. If you accidentally fall down, the eight-character ring will play a containment role. As long as you hold on to the rope tightly, you can stop further descent. The guarantee measure is to wrap the rope tied to the support point around the waist.
There are two ways to cover the climbing rope through the figure of eight, but the method of A can make the climbing rope smoother.
Guarantee measures for subsequent members
Subsequently, the member's safeguard measures are to make support points on the remaining climbing nails, trunks or screws, and then use the above method A or B to pass the climbing rope through the eight-character ring.
Step 4 hang straight down
The technique of descending to climb the ground along a fixed climbing rope is called hanging straight descent, and the method used in the past is called "tying shoulders", which is the way of winding the climbing rope around the shoulders to produce braking; But recently, the eight-character ring is the mainstream. When fixing the climbing rope, just put the rope on the trunk of the descending place. If there is no suitable tree there, you can use climbing nails as support points and set rope traps for climbing ropes; However, at this time, it is necessary to check whether the falling support point is firm. Usually, half of the climbing ropes are used, but if the descending distance is too long, two ropes can be used in combination; Don't forget to fix the rope end.
Connect two climbing ropes
When the descent distance is too long, the two ropes can be connected with a double fisherman's knot.
Rope head treatment method
Method for preventing rope from winding easily
The rope head hanging downwards must be made into double splayed knots or single knots.
Stop falling and climb again.
When the rope stops halfway or climbs again before reaching the bottom, you can tie a rope ladder knot on the rope to make a rope loop, and then put the rope around the safety belt. Once the Prussian knot is stressed, it will tighten and be fixed on the rope; The knot can be adjusted freely when no force is applied.
