Knotting method of mountaineering rope

The most commonly used equipment for mountaineering is climbing rope, and the method of connecting rope and rope with other equipment by knotting is called tying rope technology. A rope is lifeless, but once you tie a few knots to it, it becomes omnipotent at once. Rope tying technology is the basic technology to ensure the safety of rock climbing. Let's get familiar with the knotting skills!

climbing rope

There are two kinds of main rope and auxiliary rope. The length of the main rope is 60- 100 m, the diameter is about 10 mm, the weight per meter is about 0.08 kg, and the tensile strength is not less than 1800 kg. In the past, it was mainly made of jute, but recently nylon fiber has been used as raw material. Another main rope with a diameter of 8-9 mm weighs 0.06 kg per meter, and the pulling force is not less than 1600 kg, which is used for climbing steep rock walls.

Knotting method

Drag the knot.

A knot that can restrict the rope from moving in only one direction, which is suitable for towing some light objects (such as rope climbing; It can be used to drag your backpack, especially when no one helps you carry it.

Italian half knot.

This knot can be used to make sure, especially when you lose or don't bring your equipment, it's best not to drop it intentionally, or the rope will get tangled easily. Italian half knot+a runner)+a big mouth with a lock shackle, which is equivalent to a simple sling and descending device. It is the best necessary equipment for a climber to climb every time. Sometimes you can use it yourself, sometimes you can help others.

Water knot

Hit the main rope. Although it is also known as the European knot, many climbers like to use it to connect two descending ropes, because it will not get stuck when stressed like other knots, but after knotting the water knot, a rope head of about 10 cm must be left. Level the belt. The water knot is difficult to untie once it is hit on a flat belt, so it is often used on a runner that does not need to be untied.

Call it a human knot (Boolean knot).

Knots, known as the king of knots, are often tied with safety belts. Simple knot is not practical, you must add a single knot to use it. You must learn how to tie a knot on your body, on things and with your eyes closed.

A splayed knot.

Mostly used for climbing or connecting with protection points. In rock climbing competition, the protective rope must be directly connected with the safety belt with a figure-of-eight knot. It is easy to learn, distinguish between right and wrong, relatively strong and not easy to loosen. Its disadvantage is that it is not easy to untie after being stressed strongly.

Bow.

Bow can be used for mountaineering or outdoor activities, and its main uses are as follows: 1, connecting climbers in the middle of mountaineering (glacier multi-group March); 2, aerial workers can use it as a pedal ring; 3. When temporary protection is needed in the field, this knot can be used as a grasping clamp; 4. If the rope is damaged, this knot can also be used to isolate the damaged part;

Double knot

This is the most common knot (stump, iron lock, etc.). ) Connect the fixed point open in the middle, which is easy to untie when the load at the rope end disappears. The advantage is that it is easy to adjust the length of the rope between the protector and the protection point after knotting, and it is not necessary to untie it. Widely used in mountain road construction and pioneer climbing.

Flat knot

Flat knots are easy to tie and are widely used outdoors. The earliest flat knot was also used to bind objects on ships, and later it was gradually used for climbing, but the flat knot should bind objects and should not be used for climbing. But if you tie a fall-proof knot at the end of a flat knot, is it a good knot? Ping fisherman's knot? It can also be used for operations such as falling, and it is easier to untie than a fisherman's knot after being stressed.

fisherman's bend

1. Connect the ends of the rope to form a lasso for use;

2. After connecting ropes with the same diameter, do double rope descent;

3. Connect a small lasso and tie a knot;

4. Connect the auxiliary rope (diameter >; 7mm) rope for protection station;

Advantages: high strength, firmness and high safety.

Disadvantages: it is not easy to untie after being stressed, especially the wet, thin and soft rope, which can hardly be untied after several uses.

Grab the knot.

There are many ways to tie knots with different names, such as Autoblock, which plays a braking role when descending, Klemheist knot, Bachman knot, which is used as a direct iron lock for elevators, and Prusik knot that we are all familiar with. The rope for catching knots is softer than the main rope, otherwise it will affect the effect. Both ends of the rope need to be connected with double fisherman's knots. When the knot is stressed, it will grab the main rope, and it can move up and down on the main rope when it is not stressed.

Use:

1, using its temporary braking in the process of descent to play the role of secondary protection;

2. In the rescue system, the grasping knot plays the role of one-way stress;

3, temporary protection, replaceable riser;

Advantages:

Simple play, double protection;

Can protect the brake driver from being scalded during long-distance or suspension descent;

Disadvantages:

It is difficult to judge the number of winding turns. Too much will get stuck, too little will fail.

Rope tail knot

The rope end knot is a knot tied at the end of the climbing rope head, in order to prevent the rope from suddenly leaving the descender due to insufficient length during the descent. This knot is used when the weather is bad or it is getting dark and windy, or when the falling ground is out of sight. Of course, it can also protect inexperienced climbers. In recent years, rock climbing accidents caused by rope head falling off are increasing, so this kind of knot should be an indispensable part of any descent operation, especially in long-distance descent, ice climbing and natural rock climbing.

Play:

Similar to a fisherman's knot, wrap a rope head back at least 4 times;

Thread the rope head back from the wound rope loop and tighten it;

Repeat the above steps on the other rope head;

After laying, the length of each rope head and rope tail shall be at least 8 cm;

Ordinary coil rope.

Play:

1, draw the rope from one end to the other.

2. Leave 50 cm at one end as the final knot.

3. Take the same length of rope at a time and keep each strand separate (cordless loop).

4. After putting it away, tie a knot in the middle of the rope and wrap the original rope head back to form a rope loop. Use the remaining rope end to wind more than 5 times in the direction of the rope loop before passing through the rope loop.

5. Tighten both ends of the rope and tie a knot to prevent them from falling off.

Reeling rope

When climbing in the wild, sometimes you have to walk a long way, and some routes need to be climbed while walking. Therefore, it is not convenient to follow the ordinary rope winding method every time. At this time, we usually take the method of winding rope.

Play:

1, draw the rope from one end to the other.

2. Grasp the two rope ends of the rope in your hand at the same time, and leave a 3-arm-long rope on the ground to finish the fight.

3. Pick up the double-stranded rope and spread it evenly on both sides of the hand by ordinary rope winding method.

4. Pick up the reserved rope head and wrap it around the whole rope for more than 3 times.

5. After passing the rope through the middle to form a loop, pass the end of the rope and tighten it.

6. Put the rope behind your back, lift the two rope ends with both hands, cross them on your chest, bypass the waist and the whole bundle of rope.

7. Tie the remaining end of the rope in a flat knot at the waist.
