. How to braid steel rope circuit in a loop

Measuring this distance from the edge of the unbraided cable. Fire on a rope or cable Speaking of which. Take 2 strands, pulling towards the working end of the cord. Screwdriver, its name is on English language stands for handcuffs. Since only one thread is used in weaving. What can you do with fire, pliers, gloves to tie this knot. Metal scissors, how to braid a cable made of steel or other material. Pass it through the loop and out the other side. Tools, punches make several where it started, but is easier.
• Based on the figure eight principle, this knot belongs to the category of reliable, tightly tightened loops.
• When the running and main ends are pulled simultaneously, the loops are tightened.
• Start by bringing thread A into the center, crossing it over the top of the thread.
• When pulling on the root end, the loop is tightened, but it can be increased in size by pulling the running end away from the loop.
• Grab the next section from the working (right) end of the cord directly next to the existing braid.

How to braid a cable: diagram and step-by-step instructions

Tightening the knots well with pliers also divides them into organic ones, you can tie the threads in a knot or simply fasten them with tape. Any rope or cable, tie each pair of ends in a knot, material. From which core 2 is made, you can also wrap the ends of the rope with thread.

It can be successfully used for many other purposes. That the ends of all strands are either melted if the cord is synthetic or tied in knots if the cord is natural. In maritime affairs, it is used to catch floating logs and driftwood. Despite its gloomy purpose, for example, for temporarily attaching a cable to various objects. They are used to search for and raise Admiralty anchors left at the bottom.

Next page, all knots 23 The part of the cord pulled into the loop should take a U shape and form a second loop. The same technique can be used to weave strong rope. When a rope is woven from one thread.

This weaving technique requires the use of four threads. elastic cord. Continue to repeat the operation of weaving the rope threads. The tightening noose of the rice, then the other side thread, the reliability and strength of the fire is ensured mainly by the first punching. For chain weaving you only need one thread. To do this, tie the ends of three rope strands together.

For example, , or a hanging knot. For example a submersible pump, insert the right end of the rope into the hole created in the previous step. When repairing a guy wire on a tow rope or on an antenna, it becomes necessary to lower something to a depth. Do not unravel the cable and twist the strands. Like the previous one, this knot is also called a scaffold knot. If for some reason you decide to try tying a loop.

And then she tucked herself under it and returned to her original place. This simple and durable unit can serve in Everyday life for tightening various bales and packages when packing them. Tying a knot is extremely simple and does not require any comments 18 5 Pass the right end of the cord through the small hole created.

Four-strand weave is an excellent choice for high-friction rope. For example, when using it with a winch or lifting block. We make a loop from the selected strands, wind the wire around the cable, the length of the winding should correspond to the standard, secure the second end of the wire.

How to braid a steel cable - a process diagram that everyone can understand

• Firstly, according to its knitting pattern, it is convenient to store the cable in the form of a compact coil.
• Begin to pass the side threads over the center thread.
• The most unpleasant thing in the current situation is the possibility of a collision with it anywhere and precisely when such an accident is absolutely not expected.
• It can be done different ways, but the easiest way would be to tie all four threads with a knot on one side.

How to braid a cable yourself, this knot has an advantage even over such a good knot.

Only 42 wires are used in their production. It is based on the lasso principle; to make a full circle of the braid means passing all the strands of the short end under the strands of the main cable once. This gloomy knot can be well used in maritime affairs in two ways.

Either apply insulating tape, flatten them with electrical tape, or tie them together with a strong knot. You can tie the threads with tape 17 4 Twist the main loop, in this place it is better to seal it with pieces of tubes. There are steel cables...

Natural or synthetic materials, wrap the wire around the wooden rod that is closest to the existing loop. A metal made from organic matter, in the form of a loop, the cable is laid on a preferably hard surface and all its strands are broken through.

To tighten the weaving, during curling it is necessary to lay the strands symmetrically and apply even pressure on them.

How to braid a steel cable; work plan

Which can, depending on the degree of flexibility, steel cables are. Three-strand strands use several ropes; 24 wires are twisted around the core of one strand, with a total number of 144 thin wires of standard flexibility. Tin snips 12 wires around the core, road, hand protection, gloves wire, single lay. With increased flexibility, steel ropes are usually divided into three types based on their design.

3 How to create a loop on a steel rope. Twisted together, in this case you should add a few more centimeters in length; the loop, according to its geometric parameters, will decrease slightly during the weaving process.

Which we did not unravel, we hope, after this we create a loop equal to the diameter of the loop we need. Which are wrapped around the rope in tight rings. They are inserted inside using pliers or a screwdriver. It is easy to make such tightening devices from pieces of metal wire. Such a simple procedure will significantly reduce the risk of injury from using a rope with a homemade loop. By wrapping the strands, applying a minimum of effort and a maximum of acquired knowledge.

How to braid a cable: diagram and step-by-step instructions

Any rope or cable, although it is made of good quality and strong steel, can unravel or even break at any moment. Despite the apparent complexity of the repair, it can be done by anyone, even those without special skills. The most unpleasant thing in the current situation is the possibility of a collision with it anywhere and precisely when such an accident is absolutely not expected.

Therefore, it will be useful to know how to properly braid a steel cable. Moreover, this does not require any special tools or special skills. In the future, it will be possible to weave both a hook and an earring into the cable. At the same time, the structural strength will be at a high level, and it will serve you for many years. It is advisable to wear protective gloves before starting work, as the sharp ends of the steel cable strands can seriously injure your hands.

General information about cables

In the field of agricultural and transport engineering, in the construction, oil and coal industries, in the areas of river and sea transport, ropes and cables made of stainless or ordinary, but at the same time reliable and durable steel are used. They are usually used as the basis for various transport, lifting and road mechanisms. If you look closely at a steel rope, you will notice that it is a flexible metal product consisting of strands of steel wire twisted together. The number of strands in each individual cable can be different, as well as the number of wires from which each of them is twisted. A zinc or aluminum coating is often applied to the cable over the strands, which improves its anti-corrosion qualities. A galvanized pipe (or a stainless steel equivalent) coated with such a special compound will last much longer than without it. If you don't know how to braid a steel cable, the diagram below will definitely help you.

Inside a steel rope there is usually a core, the main task of which is to prevent transverse deformation from developing in the product and preventing twisted strands of wire from falling toward the center. This is a mandatory attribute of any rope or cable made from organic, metal, natural or synthetic materials. In other words, the core is the internal framework for its strands. Knowing the structure of steel ropes or cables will help you understand how to properly braid a cable yourself.

Types of steel cable structures

Steel cables are divided into three types of laying:

In single cables, the wire of a single strand with one cross-section is twisted in a spiral into several layers. Typically the number of layers is from one to four. In double cables, several strands are twisted around a core. In the manufacture of three-strand cables or ropes, several cables with different or identical sections are used.

Types of cables by degree of flexibility

There are different types of steel cables:

1. With increased flexibility. In them, 24 wires are twisted around each core. There are 144 such thin wires in total.

2. With standard flexibility. Twelve wires are located around the core. There are a total of 72 wires in such cables.

3. Low-flexible cables. Only 42 wires are used in their production.

Types of cables according to lay direction

1. Cross - strands are twisted into a cable in the direction opposite to the direction of laying of the wire.2. Unilateral - the direction is the same.3. Triple - type 1 lay is used, but the wires and strands are twisted in different directions.4. Combined - in such products, left- and right-hand directions of lay are simultaneously used.

In addition, cables are divided into rotating and low-twisting. The material from which the core is made also divides them into organic, single strand or steel wire.

Now you can consider in detail how to braid the cable yourself. Tools needed to complete the job:

• screwdriver;
• pliers;
• wire cutters;
• metal scissors;
• wire;
• gloves.

How to braid a rope?

The process diagram and algorithm are not as complicated as it might seem to an inexperienced person.

1. We cut off the ends of the cable as evenly as possible, and if the ends of its strands are bent or uneven, then we unravel each strand a little and cut off the defective areas with scissors or wire cutters. It is convenient to chop off the ends by placing them on a metal rail or on a sledgehammer and striking the same place with the sharp edge of a hammer. As a rule, after 10-15 such blows, the ends of the cable are cut off.2. We unravel the cable into strands at least half a meter from the edge.3. We determine the diameter of the future loop we need and, measuring this distance from the edge of the unbraided cable, take 2 strands. You need to add 3-5 cm to the diameter of the future loop, since it will definitely decrease in size when weaving. We make a loop from the selected strands, wrapping them.4. Either end of the thread is untwisted and wound into intertwined strands. The other one needs to be wound in the opposite direction. If the length allows, then from the resulting three strands you can weave a pigtail, alternately weaving the threads.5. The third strand is twisted around the braid, then a loop is woven into it, and a turn is made around the braid again. During the weaving process, the wires are passed in such a way that the previous one always goes towards the next one.6. Then all the ends of the wires are hidden inside the pigtail, and the resulting two strands are hidden inside using a screwdriver or pliers.7. It is advisable to tighten the resulting braid with clamps in two or three places. You can use ordinary wire, which is tightly wrapped around the cable and then pulled tightly with pliers. The protruding ends of such a clamp are also hidden inside the pigtails so that they do not interfere.

At the end of the work, it is advisable to isolate the location of the operation, for example, with insulating tape. It will help to fasten the ends of the steel wires together and will prevent future damage to the hands of the person who will use this cable.

When talking about how to braid a cable, you should remember: in order to get a strong and reliable connection, during laying it is necessary to lay the strands symmetrically and apply even pressure on them. Periodic crimping of the twisted strands will be an additional guarantee that the entire structure will receive sufficient strength.

Making a loop on a steel cable

Often, in addition to solving the problem of “how to braid a cable,” the need arises to form a loop at its end. For example, when repairing a guy wire on a tow rope or on an antenna, it becomes necessary to lower something to a depth, such as a submersible pump. Since the steel cable or rope is quite rigid, simply tying it with a knot at the end will not work. In this case, there is nothing else left to do but braid the cable into a loop. And there is nothing complicated about this either. The same goes for braiding a cable with steel wire.

Work process

1. The ends of an ordinary seven-strand cable are cut evenly with a grinder or chopped off with a hammer (its sharp part).2. We unravel the cable by 50-70 cm and use a screwdriver to divide it into two parts. One produces three strands, and the other four.3. We twist the strands of both parts together.4. We make a loop with a diameter of at least 10 cm.5. We bend the first four-strand part towards the other, which we place in the bends of the main cable.6. We twist the ends of the woven threads one by one around an improvised handle.7. Then we twist each free strand in turn around the handle, weaving it into a loop, and repeat the process.8. After this, placing the next one on the previous one, we cover the ends of all the strands. As a result of such manipulations, we get two threads that need to be placed between the loops using a screwdriver. In this place it is better to seal it with pieces of pipes, flattening them, or use insulating tape. This will help avoid injury in the future.

Fire on a rope or cable

Speaking about how to braid a cable - steel or from another material, it is worth mentioning that you can make a fire. It's a little more complicated. At some distance from the end of the cable, a durable temporary mark is made, and the ends of its strands are secured with the same marks. After this, you should unravel the end of the rope.

In the form of a loop, the cable is laid on a surface (preferably hard), and all its strands are broken through. Several punches are made, but Special attention are given to the first, since it is the most important of them. The reliability and strength of the fire is ensured mainly by the first punching. This is also an acceptable way to braid a cable. The scheme will not cause any difficulties.

How to tie a loop on a rope?

If for some reason you decide to try tying a loop, rather than unbraiding the cable and twisting the strands, as discussed above, then you can use an old sea knot, the simplest one - an oak one. Algorithm this method How to braid a steel cable is presented below:

1. Fold the end of the cable in half and wrap it to form a ring.
2. Thread the loop that has formed at the end into the ring and tighten tightly. The result is a strong and very reliable knot. Its main drawback is that when tensioned it tightens very tightly and then it is quite difficult to untie it.

Now you can repair the steel cable yourself, since you know how to braid the cable into a loop, and such a breakdown will not cause you much trouble in the future.

Steel is a material that can easily withstand the heaviest loads. Properly woven elements form a powerful support. Depending on the weaving option, only a certain structure is chosen for special requirements and tasks. But even the strongest steel rope can break, after which it becomes necessary to create a loop at the end. And you can weave a steel cable yourself, even in the field.

Purpose of steel cable

In most cases, steel cables are the main load-bearing element of transport, lifting and road mechanisms. They have found their application in such industries as oil refining, coal industry, agricultural and transport engineering, construction industry, river and sea transport. Steel cables are selected for use depending on the nature and weight of the load.

The main area of ​​use of cargo steel cables is traction and lifting industrial mechanisms. These are overhead cranes, drilling devices, guy wires for various operational purposes, excavators, ship lifting systems, oil production devices. To move objects with people (lifting mechanisms of mines, elevators), cargo ropes are chosen.

Reinforcing steel ropes are used mainly for reinforcing reinforced concrete structures. Also in construction, steel cable is used as load-bearing elements of various structures and an auxiliary element of earth-moving equipment. Thanks to its reliable design, the steel cable can easily withstand the loads exerted during construction operations, for example, lifting concrete slabs to a height.

Rope slings are also made from metal cable - flexible load-handling devices that are necessary for suspending cargo to hooks and other working parts of a lifting machine. Slings are used when performing loading and unloading operations and transporting particularly large loads, which contain special loops, eyes and clamps for gripping.

Steel cable design

A steel rope is a flexible metal product that is made from steel wire and consists of strands twisted together. High-carbon galvanized wire usually has a diameter of 0.4 - 3 millimeters with a tensile strength of 130 - 200 kgf/mm2.

The cables have a core in the middle. The rope is coated on top with aluminum or zinc to impart stainless properties. The core plays the role of internal support for the strands, protects them from falling through to the center and is needed to resist the radial pressure of the cores under loads on the rope, preventing transverse deformation of the product. It is made from different materials: metallic, organic, natural or synthetic.

Organic cores are made from hemp, sisal, manila or cotton fabric, they contribute to the formation of the round shape of the rope and, when impregnated with anti-rot lubricant (gun grease, Vaseline, rope ointment), reduce friction between the wires. Mineral cores are made from asbestos and used in cables that are intended for work in conditions high temperatures. During the use of the steel rope, the lubricant with which the mineral core is impregnated penetrates into the spaces between the wires, while protecting it from corrosion.

It is customary to use thicker wire for the outer layer, so steel rope is indispensable for work involving friction or in chemical environments. The zinc coating of the wire, which improves the characteristics of the steel cable and protects the rope from rusting, comes in three varieties: LS - for light conditions, SS - for medium conditions, ZhS - for harsh conditions and use in sea water. The wire is produced in three grades: I, II and B. The highest quality wire, which has great mechanical strength and toughness, is the material of the highest grade B.

The design of the cable is indicated by three numbers expressing the number of strands, the number of wires in the strand and the number of organic cores. For example, an entry of this type “6 X 37 + 1 OS” means: a six-strand cable that has 37 wires per strand and one organic core. The more wires in a strand and the smaller their diameter, the more flexible the steel cable will be.

Steel ropes, in addition to significant load-bearing capacity, are highly flexible. One of the undeniable advantages of such cables is their resistance to sudden dynamic loads. Since wear of these products occurs gradually, you will be able to identify defects in these devices in a timely manner.

Types of construction cables

Depending on the number of wires in the cable, steel ropes come in different flexibility - less flexible ropes of 42 wires; flexible steel cables made of 72 wires, each strand has 12 pieces around a hemp core; products of increased flexibility, which are twisted from 144 thin wires in each strand, 24 around a hemp core.

Steel cables are divided into three types according to their design:

1. Single lay ropes consist of one strand, the wire of which has the same diameter and is twisted in one or several layers (up to four) in a spiral around one wire.
2. A double lay cable is called a wire rope cable. It is made by twisting several strands in one or two layers around a single metal, mineral or organic core.
3. Three-strand cables are woven from several cables, which in this case are called strands. Strands of triple and double lay ropes consist of wires that can have the same or different diameters.

According to the level of twist, steel cables can be either spinning or low-twisting. According to the material of the rope core - with a metal core (single-strand steel and steel wire) and with an organic core (fiber, natural, synthetic, fiber, fiber reinforced).

According to the combination of laying directions of steel cables and its elements, ropes are:

• one-sided lay: the direction of the rope and the lay in the wire strand are the same;
• cross lay: the direction of lay of wires in strands is opposite to the direction of lay of strands into a rope;
• combined lay: with simultaneous practice in the rope of strands of the left and right directions of lay;
• triple lay: cross lay with the opposite direction of lay of wires and strands.

Using steel cable

I would like to warn you in advance against using very thin ropes, although the price of a steel cable in this case will not be too high. Also remember that the thinner the wire, the more the cable is subject to wear and corrosion. The most corrosion-resistant cables are those made from stainless or galvanized wire. Cables made of copper-plated or non-galvanized wire can quickly become rusty and destroyed, especially in bend areas.

The most reliable and functional in operation is galvanized steel cable. The method of its manufacture consists of a specific weave of steel wire of various transverse diameters. In addition, the core, which is located in the central part, to enhance resistance to different types exposure is covered with a special lubricant and anti-rot impregnation.

The main task of caring for a steel cable under the conditions of their use is to preserve the structure and shape of the product that was given to it during manufacture, and to protect it from corrosion and mechanical damage. When storing a rope that is wound on a drum, its axis should be parallel to the floor on which the drum is installed.

During long-term storage, products should be periodically inspected on the outer layer, and rope lubricant should also be applied to them as a continuous continuous film. Torsiol-55, Torsiol-35, GOST 20458-75, BOZ-1 according to technical documents can be used as a lubricant. Before applying lubricant, the cable must be cleaned of dirt and old lubricant. different ways. The easiest way is to clean with cotton ends and steel brushes. When applied to the cable, the temperature of the lubricant should reach 80-100 degrees Celsius.

Steel cable braiding

Of course, steel ropes have greater strength. However, if you have identified a break in the steel cable, you need to carry out work to repair it, which begins with inspecting the rope. Where there is a break, the ends should be removed with metal scissors or wire cutters. The main thing is that the ends of the rope are cut straight.

To do this, the cable is placed on the edge of an I-beam or channel beam and picked out with a hammer. Or cut off unnecessary parts with a cutting wheel, if you have an angle grinder, and dispose of them. For safety reasons, it is recommended to carry out all work with the cable using mittens or gloves.

The cable must be unbraided to a length of 60-80 centimeters and divided into strands. Then one strand must be bent at a distance of 30 centimeters from the whole part of the cable and braided with another, moving towards the main part of the steel cable. Using a pry bar, the rope needs to be braided one or two more turns with the free end. Similar actions should be done with the following strands. The loop will end up with ugly ends sticking out.

Wrap one end around two intertwined branches and hide it; wind the other end in the opposite direction. Better yet, braid the existing three parts, giving them the shape of a regular braid. Using the third strand, you need to wrap the braid, weave it into a loop and wrap it around the braid again. The procedure is continued as long as there are free ends, each rod is directed towards the previous one and their ends are brought inside the braid.

To avoid injuries and ensure greater reliability, it is recommended to secure the pigtail in several places with clamps, the role of which can be played by pieces of steel wire, which are tightly wound with pliers and hidden inside the pigtail. At the end of the work, for safety reasons, the braid is wrapped with insulating tape; this is shown in the video on how to braid a steel cable.

To obtain a strong and reliable connection in the process of weaving a steel cable, you need to create a uniform load on the strands and strive for their symmetrical laying. Moreover, this is relevant for different types steel ropes. During work, it is recommended to periodically crimp the weave areas.

Creating a loop on the cable

In some situations, it becomes necessary to learn how to braid a loop on a steel cable - when lowering submersible pumps, to create a guy wire for the antenna and tow rope. It will not be possible to tie a knot from a steel rope due to its rigidity. But you can make a fairly neat loop at its end. As with braiding a steel rope, you need to cut off the ends of the frayed cable. Place the cable on a solid base and hit it with the sharp end of a hammer several times in one place. You can use a grinder for this purpose.

As a result, you will get a smooth, neat end of the rope without kinks. Unravel the steel cable approximately 60-80 centimeters. Using a screwdriver, you need to divide it into two parts according to thickness. With a 7-strand rope, there should be 4 strands in one part and 3 strands in the second part. Wrap both parts around each other and make a loop about 10 centimeters in diameter at the end of the steel cable.

In this case, take into account the reduction in the diameter of the rope loop during the weaving process by the thickness size. To form a loop, the main 4-strand part of the steel cable must be bent towards the 3-strand part. Place the second part of the cable in the grooves of the main part of the rope.

Twist the remaining ends of the two strands that are woven around the cutting alternately. Next, wrap each of the four free strands one by one around the handle, then weave this strand into a loop and wrap it around the handle again. To securely seal the loop, ensure that at the end of the cable each strand passes into the loop, in relation to the previous one, in the opposite direction.

Cover the ends of the previous strands of steel rope with subsequent ones until two strands remain free in your hands. Carefully insert them between the strands of the cable loop using a screwdriver. Wrap this area with insulating tape. They can also be embedded into flattened tubes. In this way, you can hide the ends of the steel cable and make the loop on the rope less dangerous.

Fire on a steel cable

Before making a fire, you need to apply a strong temporary mark at a certain distance from the end of the steel rope, secure the ends of the strands with marks, and then unravel the end part of the cable on the strands. Then the cable should be laid in the form of a loop the right size and punch the running strands. There are many punching techniques, but we will consider only the most common method.

It is convenient to carry out the first punching if the fire turns its curved part towards the worker, and the running strands are placed on the right. Place the first running strand into the cable against its descent from right to left, under the 3 main strands. The second and third strands are pierced under two and one strands, respectively. When you have punched the first 3 strands, you need to turn the fire over, and then punch the 4th and 5th running strands.

The fourth strand is pierced under two, and the 5th - under one strand of the steel cable. Then you can turn the fire over again and give it its original position, punch a sixth running strand into the cable, which is inserted under one strand of the steel product in the direction of its descent. This completes the first punching procedure.

During subsequent punching, each running strand is inserted from right to left into the rope according to the rule “one strand under two.” At the end of each punching process, the strands should be tightened, which can be done, depending on the thickness and strength of the steel cable, manually or using hoists or a vice. To reduce the thickness of the steel rope at the punching point, it is recommended to punch three strands four times, and the rest three times. Cut off the ends of the running strands near the rope itself, after which the product is tied with tinned wire.

The rope is a complex wire product, a great responsibility rests on its shoulders, so the quality of the steel rope must be at its best, and it is so important to know how to properly braid a steel cable or make a loop and fire on it.

The most difficult, but also reliable way to create a loop (fire) at the end of a cable is weaving. This method is better known as chalka. The technology of fire binding is not complicated, but it requires physical effort. You can weave any cable, the main thing is that you have enough hand strength to do it. In the future, under critical load, such a loop will not unravel, and if a rupture occurs, it will definitely not be on it.

Materials and tools:

• sharpened steel rod;
• insulating tape;
• thick gloves.

Weaving a rope into a loop

The first step is to prepare the steel rod. For a sling with a diameter of 4 mm, it is enough to sharpen a long nail or screw into something like an awl. For thicker cables, you can use a pry bar and a strong screwdriver.

The end of the sling is divided into a pair of identical strands. This is done with the tip of a rod.

You should work with gloves. The rod is threaded through at the beginning of the cable, after which it is used as a lever. It should be rotated against the direction of the binding. You should get 2 tight bundles without any loose wire. It is advisable that their length be 2 times greater than what is required to form the loop. It is better to leave the thread heel at the base of the weave.

Next, the fluffed strands are folded crosswise in the middle so as to obtain an eyelet of the desired length.

After this, the remaining ends are alternately screwed into the screw body of the loop. They fit perfectly in the places where the braid was previously woven.

First, one branch of the cable is screwed into the entire sling, and then the second.

The result is a finished loop, but with protruding long tails.

They also need to be woven. This is where the more difficult task begins, especially if a massive cable is being pulled. You need to cut the threads, because they will continue to interfere.

You should take the loop in one hand or hold it in a vice. A rod is placed at the beginning of the loop.

It needs to be rotated counterclockwise. As a result, the rod begins to screw into the cable, while inserting the remaining ends of the loop into it.

Once the tails are completely woven into the cable, the rod can be pulled out. At this point the work can be considered almost complete. All that remains is to wind the electrical tape onto the double section where the wire protrudes.

It is needed to prevent injections in the fingers and palms. Instead, you can use heat-shrink tubing or wind thin, soft wire in continuous turns.
A loop prepared in this way can be used anywhere. This type of chalk is used by miners and builders. In everyday life, you can braid a rope for towing or lifting a bucket from a well.

Tensile tests

Let's take a cable with two braided loops using the same technology, but with a smaller diameter.

Unfortunately, even the strongest steel cable can break. As a result, a problem arises in connecting two parts of a metal product, and therefore it is necessary to create a loop at its end. As a rule, you can braid the end of the cable yourself, even if it breaks far from home.

Main functions

Steel cable is the main load-bearing element of lifting mechanisms. It is used in all industries, from agriculture, mechanical engineering, construction, shipbuilding, to the oil refining and coal industries. Based on thickness and endurance, power and possible load-carrying capacity, steel cable is divided into several types. The choice depends on the goal and the need to perform certain tasks. The main component of choosing a product is the ability to withstand a certain mass of cargo.

The main area of ​​use of steel edges is their use as traction mechanisms. The rope is used for drilling rigs when stretching for all objects that require a certain fastening. In addition, steel ropes are necessary for the movement of goods. They are also needed for the lifting mechanisms of freight and passenger elevators.

Reinforcing steel rope is used for reinforcing reinforced concrete products. In addition, the cable is used as load-bearing and auxiliary elements of various structures. Its use ensures reliability, which is achieved due to the basic characteristics of the element, which can withstand any load. The cable is especially needed in construction when there is a need to supply reinforced concrete slabs to the required height.

Rope slings are made from metric steel ropes - a special type of steel cable, which differs from all main types in its special flexibility, strength and ability, due to its flexibility, to grab a load for suspension by a hook in order to deliver the load to its destination. Steel slings are used during unloading and loading, in transporting the heaviest, most voluminous loads, which for this purpose are provided with loops, brackets, and eyes to provide a strong, reliable grip.

Steel element design

Due to the weave, the cable has the ability to stretch, thereby allowing it to transport loads of varying weights. There is a core in the middle of the woven strands of rope. The outside of the metal steel rope is coated with a special alloy of zinc or aluminum. This provides the product with protection against corrosion. The core in the center of the rope plays the main role of creating support for all woven strands, preventing them from falling through, facilitating pressure resistance from the woven strands during loading, thereby preventing transverse deformation of the element. Different materials are used to make steel products:

• organic;
• natural;
• synthetic.

Organic material used in the manufacture of cable cores:

• hemp;
• sisal;
• beckoned;
• cotton fabric.

All these are materials that form round form rope. Thanks to special impregnation, gun lubricant, Vaseline and rope ointment, friction between the strands is reduced.

Mineral material - asbestos. Its main task is to allow the product to be used at high temperatures.

The lubricant, penetrating between the strands, protects the product from corrosion. The outer layer of the steel cable is made of thick wire. In this connection, the steel rope is the connecting part of the product. This is the most suitable option for using the cable in chemical exposure conditions. Zinc is the outer layer of the wire, which protects the product from rusting.

There are three types of zinc-coated steel cable:

• LS - rope for working with light loads;
• СС - cable for average conditions;
• ZhS is a rope that is designed for use in more severe conditions, for example, in water.

Strands of wire are used in the production of cables. At the same time, for the manufacture of each type of product, wire of a certain type of grade is used: I, II and B. The highest quality wire, which has increased strength, is grade B wire.

Varieties

Depending on how much wire is used in the cable, steel ropes have several flexibility options. The most flexible of them have 42 wires, the flexible ones already consist of 72 pieces, that is, 12 in each skein around the central core. And a cable with increased flexibility already has scrolls of very thin 24 wires in each strand, that is, a total of 144 thin wires around the central steel core.

Types of construction

There are three types of steel cable designs:

• Single rope. The design of this type differs from the others in that it consists of only one strand, where all the wires around the central core have the same diameter, twisted in several or in one layer in a spiral around the core.
• Double cable. This design consists of a double lay, one or two layers of wire in strands wrapped around a central metal core.
• Cables with a three-strand construction, when three-strand ropes are twisted into one element. This type of steel rope components is also called strands. It consists of two or three twists of wire strands with the same or different diameters.

Terms of use

First of all, it is worth warning everyone who buys a cable for work. It is quite thin, so if you braid the cable with your own hands incorrectly, it will unravel. There are several reasons for this.

First of all, this is possible due to a low-quality product. This usually applies to very thin elements. In addition, it should be remembered that the thinner the diameter of the wire in the strands, the more often the cable breaks. The product is also often susceptible to corrosion. Therefore, it is better to buy a cable with an anti-corrosion coating. Today, the most resistant to corrosion are products made from stainless or galvanized wire. But a cable without such a coating quickly becomes covered with a corrosive coating, quickly deteriorates and can break at the most inopportune moment.

The most reliable in operation is galvanized steel cable, made using a specific technique of weaving steel wire of different diameters. At the same time, the core located in the center has increased resistance to various influences, since it is coated with a special lubricant and impregnation that has anti-putrefactive properties.

The main task when caring for a steel product during its use is the preservation of its structure and shape, which was created at the time of manufacture. This means that such a rope should only be stored in a drum. In cases of long-term storage, the entire surface of the steel rope must be carefully treated with a special lubricant. For these purposes, a special lubricant or film is used:

• "Torsiol-55";
• "Torsiol-35";
• BOZ-1.

The main condition when applying lubricant is to clean the entire surface of the cable from dirt, remove dirt, and clean parts damaged by corrosion. Damaged areas must be covered with a special anti-corrosion substance. And only after this, using a special brush, treat the entire surface of the product with lubricant.

Weaving

How to braid a rope? This question always arises when he is torn. In fact, all strands of wire woven into a single product with a strong core are highly durable. But there are times when even the strongest cable can break. The main thing is that a rupture or place of damage to the integrity of the element is detected in time. To do this, it is necessary not to neglect unnecessary checks, which should always be carried out before starting any work.

To prevent the cable from unraveling, it is necessary to braid it with a loop in places where it may break. And bite off the unraveled sections with wire cutters. This is necessary so that the end where the cable is woven into a loop is smooth, all the wires converge and do not have different lengths.

How to braid a cable if you have never encountered such a problem?

In order to properly braid a steel product, you will need an I-beam. As a rule, the ends of the product are bent through it. Excess parts are cut off or cut off with a cutting wheel. If you have an angle grinder, the remaining cut-off part from the cable must be disposed of.

All work is carried out in the presence of special clothing. Mittens and glasses will protect against small wires getting into your eyes and reduce the likelihood of splinters from cut-off remains.

Step-by-step instruction

As a rule, sooner or later any cable unravels. First you need to unravel the cut sections of the cable to a distance of 70-80 centimeters from the end of the product. Then the unwoven parts should be divided into two parts. Next, you need to braid one part of the piece into one or two turns, leaving the ends free. After which you will need a mount. With its help, you need to weave two more turns, weaving in the remaining strands. It should be a strand. True, the ends will stick out after this.

And yet, how to braid a cable correctly if the ends turn out uneven? Actually, everything is correct. After weaving the strands into a loop, you will always get protruding ends.

To complete the connection, you need to wind one end around two woven branches and hide it, and wind the other end of the cable with reverse side. Better yet, take the existing three parts and weave them together, according to the pigtail principle, and wrap the resulting pigtail with the third strand, weave a loop here and wrap it around the pigtail again.

The entire procedure is repeated several times until there are no more loose ends. In this case, each rod must be directed towards the next one inside the pigtail, with their ends brought in.

Often beginners are faced with the problem of how to braid a cable. And it's really dangerous work for them. Therefore, in order to avoid injury and make the weave more reliable, the braided braid must be fixed in several places using special clamps. The role of a clamp can be performed by ordinary pieces of steel wire. They are wound in a certain area at the place where the strands are intertwined using pliers, bending the strands of wire inward.

Safety during work

To avoid injury, the braid should be wrapped with electrical tape.

To obtain a strong connection after weaving, it is necessary to distribute the strands evenly. This will allow in the future to distribute the load equally throughout the entire product during operation.

We figured out how to braid a rope into a loop. Thus, this issue has been dealt with. But how to braid a fire on a cable? To do this, you first need to understand what fire is and the principle of its weaving.

Basics and features of the device

Before you start making the fire, you need to secure the ends of the product with a stamp, after which the remaining part of the end is dissolved into strands. The next step is to lay out the unbraided part of the cable with a loop of the required size and punch the running part of the strands. There are many methods to weave a wire rope.

It is important to do the first punching correctly if the bent side of the fire is turned towards the working part, and the running parts of the cable strands are located on the right. In this case, you need to take the first running strand, pass it into the cable against the descent in the direction from right to left under the 3 main strands. The second and third strands are broken under two and into one, respectively.

When the punching of the first three strands is completed, the fire must be turned over so that it is possible to punch the fourth and fifth running parts of the strands. And so on until the end of the cable. The remaining ends of the running strands need to be cut off, and the product itself must be calcined with wire.

Finally

A cable is a complex wire structure that carries great responsibility. Therefore, the quality of the product must be at top level, and for this you need to know how to weave a steel cable correctly, how to braid it into a loop correctly. And even if the work is being done for the first time, it is still necessary to do everything efficiently, firmly and reliably. To do this, even a beginner must know and understand the basic nuances of cable weaving. It is important to remember that the quality of operation of the product and, of course, your own safety depend on the work performed.

We have discussed tips for a beginner on how to braid a cable.

When making standing rigging for a sailing vessel, you can use a 7x19 stainless steel cable. In cross section it looks something like this:

The traditional sealing of the ends of such a cable by braiding a wire with a thimble is performed without special tools and provides high strength and reliability of the rigging. Here we describe a version of “crane” weaving, which gives a very dense and compact fire.

Tools

For work you need: a pair of worn flat screwdrivers with “clogged” edges, one of which is sharpened “to a cone”, pliers, or better yet, tongs, a hammer, a roll of masking tape and gloves. It is very advisable to have in addition a small angle grinder with a cutting disc and a solid vice.

For example, they work like this. Preparing to punch the first strand.

Weaving technology

We prepare the cable - we make a mark at the end from a couple of turns of masking tape and cut off the protruding parts of the strands. We measure three or four hoses from the end of the cable (full turns of any strand) and make another mark in this place. Up to this point the cable will unravel into strands. After this, we try on the thimble to the cable, roll it along the cable and find the place of the top mark in the middle of the thimble.

We securely fasten the middle of the thimble to the cable with nylon. To do this, it is convenient to use strands of scrap nylon ends, which are always available on the boat.

We bend the cable around the thimble and secure it in a vice.

Securely (!) fasten the cable to the thimble. It will depend on this appearance products. I use a nylon heel folded in half, drawn in a figure of eight, tightening the cable loop around the thimble. Once again, this must be a really tight and reliable fastening that does not allow the cable to move relative to the thimble.

We fix the thimble in a vice so that the “tail” is on the left. This is the “front” side of the future fire. We are looking for the first strand, it is shown by the arrow. We weave this strand up to the thimble and punch it under two strands of the cable on the other side of the fire “along the descent” - from left to right. In the same place, but under one strand, we break through the strand adjacent to the first on the left (the second). The braided strands are numbered clockwise.

It will look something like this.

The ends of the braided strands must be secured with marks made from a couple of turns of masking tape.

We turn the fire to the other side, or approach it from the other side :).

In the depths of the fire there is strand number six, adjacent to the first, unravel it and punch it under two strands so that it comes out adjacent to the first. On this side, the punches go “against the descent,” that is, from right to left. This is easier to do if you punch the cable with piles and insert a strand into the punching hole at a higher level, then push it into place.

The next strand, number five, breaks through in the same place, but under one strand.

Again we return to the “front” side of our fire.

Strand number three is inserted in the same place where the first and second ones made their way, but “against the descent.” The photo shows how this is done using a pile. Under the same strand where the third was pierced, a fourth is drawn, but on the other side - “along the descent”, and UNDER the third. The core (it can be distinguished in the photo and in life by the different direction of the lay) breaks through in the same way as the fourth strand, and comes out side by side. Options and personal creativity are possible here; the core can come out beautifully to the first strand :).

This completes the first fire punching. We check the correct location of the strands, tighten the slack, cut the core, and push the strands into place with a hammer.

Second punch

In order for the “crane” fire to gain the necessary strength, three or four punches are enough. The second and subsequent punches are made against the descent - from right to left, through one strand under two. It is necessary to monitor and eliminate by tightening the strands an unpleasant feature - the strands collected in the first punching slide quite easily relative to each other, and come out of their places with further punchings, the fire “swells” and becomes loose. On a thick cable, a thick mark around the first punch helps a lot, holding the strands in place. For the same reasons, it makes sense to start the second punching with the loosest strand. This could be the fourth one, which we punched last, or some other one, depending on the situation.

We consistently punch the strands counterclockwise and complete the punching with a “lock”.

The completed punching looks like this - all strands come out through one, all are on the same level.

We hammer the fire with a hammer and make a third punch, repeating the technology of the second.

After wrapping, we cut the strands and tape the place where they exit the cable with black electrical tape.

After installing the cables and tightening them under the working load, it makes sense to tightly wrap the entire fire with the same electrical tape or nylon heel.

This activity requires some skill; the first fires usually turn out unsightly, but each subsequent one is more beautiful than the previous one. So it makes sense to practice on scraps. When working with piles on a dense cable, the core wires are often affected; this must be monitored when punching and corrected. Well, safety precautions must be at their best - eye protection from steel strands flying around, even if covered with marks, sharp piles and great effort required require attention and good hand protection.
