Leader If you have been climbing, there will be time for a fall; in fact, if you do not fall, you may not try your limit. There are basically two types of fall: 1. You know what's going to happen, even if it's a very short time. 2. You don't know what's going to happen. It's like a broken hand or no obvious reason to drop suddenly. The first one gives you a little time to prepare for a fall, and sometimes you can push it away from the climbing wall and inform your protector to tighten the rope. In this way, you can adjust your position to free your hands and use your feet to push the rope against the climbing wall. The sudden drop is more dangerous, because when you realize that the body has fallen (that is, the part that is surprised), it is not enough to respond. When it falls, it swings and it hits something that doesn't move, or suddenly the momentum may violently pull you toward the climbing wall. Here are some things to watch out for when the leader climbs: 1. Let the master rope be in the best condition at all times and believe in your defender 2. Stay in a falling posture to prevent the head from falling downwards 3. Pay attention to the extension of the main rope and avoid long distance drops 4. Avoid the prominent cornerstone 5. Please pay attention to the pendulum effect when you are climbing [Pendulum] Defender 1, first pay attention to their own safety, can play protective purposes 2, watching the climber's every move 3, protective methods must be correct, immediately stop the climber down 4, the brake must not leave the climbing rope; avoid burning Hand 5, put the brake on the back of the thigh; even add a guide hand tightly catch the brake rope 6, the climber has a major over-protection, the guards use a foot wall to avoid bruising impact When the climber falls, energy is ensured by the system and especially by the rope. If the rope can effectively absorb energy, the impact of the climber will be greatly reduced. When a climber falls and stops, the constant force it produces is called 'impact'. Its value depends on 'fall rate / rate of fall', the weight of the climber and the ability of the rope to absorb energy when it falls. Drop rate The fall rate determines the severity of the fall: the drop rate is the ratio of the length of the rope released divided by the drop distance, and the value is between 0 and 2. The greater the fall rate, the greater the severity of the fall. So the severity of the fall is not the distance to fall, because when the rope is longer, it can extend more to withstand the impact of the fall. Specification requirements When using a single rope, the specification requires that an 80 kg item fall at the first fall rate equal to 2 and the impact force generated shall not be greater than 1200 kg, whereas the impact force of a 55 kg item shall not be greater than the impact force of a 55 kg item. 800 kg weight. impact It is a force that is generated by the fall and transmitted to the climber. At the same time, it is transmitted along the rope to the fixed point, the buckle and the protector. The protection of the rope is to absorb the falling energy to reduce the impact, so it is very important to choose the right rope. The quality of a rope depends entirely on the impact it generates when it falls and whether it can continue to maintain its characteristics after multiple declines. Maximum impact force Based on the specifications of the International Mountaineering Association (UIAA), the impact force generated at the first fall of the drop rate equal to 2 is the maximum impact force, which is also a basic characteristic of a rope. Impact change process In the continuous decline, the rope's power performance will continue to decrease, and the resulting impact will increase. If the impact force of a new rope at the first fall is close to the upper limit, its life will not be too long. Protectors' responsibilities and attitudes Although there is a very safe brake, the safety is only 50 per cent, and another 50 per cent is on the defender. Because there is no defender to brake the rope, the climber will still fall to the end; the other case is that the defender cannot brake the climbing rope in time, and when the brakes are to be braked, the rope is driven by the followers. Accelerate, if defenders catch ropes by hand. His hands will be burned and burned, and pain will be caused by the burns. Because of the pain, of course, he will let go. Because of this series of relationships, the life of the fallen ones has cooled by 90%. Therefore, the guards must wake up when they are protecting. Twelve spirit, always pay attention to the movement of the climber, such as climbers encounter more difficulties, they must pay more attention to the climber's life is controlled in the hands of defenders. So as a defender, you can't relax at any time. The following are the responsibilities and attitudes of defenders: Climbing 1. Ensure that climbers and their physical condition are able to cope with this event 2. Ensure that there is no debris in the climbing stone line area to prevent protection 3. Check all climbing equipment 4. Correct and skilled use of protective equipment 5. Ensure climbing The seat belts have been 'anti-wearing' and correctly playing 'anti-wearing 8 characters' Climbing 1. The movement of those who want to climb 2. The communication between the three parties should be maintained 3. Do not chat with other people or even make a mobile phone 4. The guard should always pay attention to whether the climbing rope is too loose. If it is too loose, it will lose its protective effect. Be firm with climbing ropes until the climber has dropped to safety. 6. Protect the position properly. Do not leave the wall too far. Ningbo XISXI E-commerce Co., Ltd , https://www.petspetstoys.com
6. Protect your body with your hands and feet when you fall. Avoid body hitting the wall. When necessary, use your hand to hold the rope and keep your body in balance. 7. When you fall, use your feet to make a little force to leave the wall and touch the wall again. Protect your body so that it does not hit the wall. 8. Be careful not to hurt your hands or feet. 9. Expected falls will let you know what to do
6, to ensure that their own safety belt has been 'anti-wear' and the lock has been locked steel lock has been 'locked'
7, to ensure the main rope in the guide side; brake rope on the brake side 8, to ensure that the main rope is not entangled with the brake rope
