Steel wire ropes need to be checked repeatedly during production to ensure that they are foolproof. If there are quality problems with the steel wire rope, accidents will occur during the use of the steel wire rope. So what are the main factors affecting the quality of  steel wire ropes? Let me explain to you. 1. The quality of steel wire: The quality of steel wire is mainly determined by the materials and production processes used to produce the steel wire. The unique cold drawing process produces high-quality steel wire. 2. The size of the rope core: The main function of the rope core in the steel wire rope is to support the rope strands and ensure the balance of oil inside the steel wire rope. In exchanges with foreign countries, we learned that the grease content should account for about 1.5% of the total weight of the steel wire rope. Compared with triangular strands, round strand steel wire ropes have a smaller wire capacity than triangular strands. At the same time, the hemp core content of round strands is much greater than that of triangular strands. The grease content of triangular strands and round strands of the same length is basically the same, but because the hemp core content of triangular strands is less than that of round strands, the grease content in the hemp core of triangular strands is much greater than that of triangular strands. It can be concluded that the probability of vicious oil leakage in round strand wire rope during use is lower than that of triangular strand wire rope. 3. The quality of grease: The grease inside the oil-containing wire rope mainly plays the role of lubrication, corrosion prevention and rust prevention, and ensuring the friction coefficient. Good grease can well protect the wire rope and always keep the wire rope in a very stable running state, while poor grease will cause the wire rope to lack oil early, throw oil a lot, and even major accidents such as rope slip. Therefore, the quality of grease is also an important factor affecting the life of the wire rope.

In simple terms, wire rope is a metal rope made of multiple strands of fine steel twisted into strands, and then twisted into a spiral shape with a certain number of strands at the center. Wire ropes are used in a wide range of industries, such as transportation industry, lifting and hoisting industry, etc. In order to help everyone understand the industry where wire ropes are used when working with them, the editor has specially collected some information to share here and hopes it will be helpful to you. Let's take a look without saying too much.   Since wire ropes are used, it is natural to understand their advantages and characteristics. Because wire ropes are made of metal materials, they are naturally incomparable to other materials in terms of strength and so on. They have high strength and good elasticity. Wire ropes made of good steel also have good toughness and are soft and can be wound around some specific goods and have a light weight that will not increase their weight.   Features of wire ropes: Wire ropes can transmit long-distance loads and have a reliable safety factor. When not in use, they are coiled together and do not take up space or space, making them easy to carry. The important point is that they are made of metal materials and are therefore more wear-resistant.   Wire ropes are widely used in many industries, such as machinery, shipbuilding, mining, metallurgy, forestry, and other industries, as well as the lifting and hoisting industry for cargo handling.   The above is a brief introduction to wire ropes. If you need it, Jingle Fasteners will serve you wholeheartedly.

Steel wire ropes are usually classified according to the material of the steel wire, the surface state, the twisting method and the purpose of the steel wire rope. So today, let's follow the editor to learn about the steel wire ropes in the first two classification methods. First, it is classified according to the material. Steel wire ropes are divided into carbon steel wire ropes and stainless steel wire ropes. The former is mainly twisted with steel wires with good carbon structure as raw materials; the latter stainless steel wire rope is twisted with stainless steel wire. Secondly, it is classified according to the surface state of the steel wire rope. This classification is divided into four types, including phosphating coated steel wire rope, galvanized steel wire rope, plastic coated steel wire rope and smooth steel wire rope. Phosphating coated steel wire rope is also called phosphating steel wire rope. This kind of steel wire rope cannot be processed by cold drawing before twisting, but directly twisted into strands, steel cores and steel wire ropes. The phosphating film on the surface can improve the wear resistance and corrosion resistance of the surface of the steel wire used for rope making. Galvanized steel wire rope includes two methods: hot-dip galvanizing and electrogalvanizing. In simple terms, the protection of the steel wire by the galvanized layer is positive protection. The thicker the galvanized layer on the surface, the stronger the anti-corrosion ability. Plastic-coated steel wire rope is a steel wire rope with a certain thickness of plastic on the outer surface or the surface layer of the strand. Smooth steel wire rope requires heat treatment and surface preparation of the raw materials before cold drawing to obtain rope-making steel wire. The steel wire does not need any surface treatment to be directly twisted into strand rope, steel core and steel wire rope.

With the improvement of customer demand and the development strategy of wire rope enterprises, domestic wire rope and cable grease enterprises have improved in many aspects from variety, quality to market competitiveness after ten years of scientific research, production and technical services. They can provide a full range of metal product lubrication and anti-rust products in the domestic and foreign markets. Some products have passed ISO9001:2000 quality system certification, and some products have passed safety certification and ROHS certification. They serve domestic wire rope, cable, and steel wire manufacturers and internationally renowned companies, and provide multi-faceted solutions for lubrication and anti-rust of metal products. 1. Lubrication and maintenance of elevator wire rope Elevator wire rope is a tool that transmits power by friction. It works frequently and runs at a high speed. It requires good friction between the wire rope and the traction wheel, good lubricity between the steel wires and the rope strands, good permeability of the maintenance oil, and good adhesion of the grease to achieve stable and long-life operation. This requires the grease to achieve the following properties: the elevator rope hemp core grease must have high viscosity to slowly supply lubricant to the outer steel wire; the surface grease must have good adhesion and high friction coefficient; the maintenance oil must also have good permeability and construction convenience. 2. Anti-corrosion grease for steel core aluminum stranded wire and aluminum stranded wire Steel core aluminum stranded wire and aluminum stranded wire are overhead conductors. They work under harsh conditions and require anti-corrosion treatment. This is an international practice. Both European and international electricians have relevant standards. Bridge cables also require anti-corrosion treatment. The anti-corrosion grease for steel core aluminum stranded wire has a high dropping point, good low-temperature adhesion, neutral grease, good rust resistance, and meets the two standards of BSEN50326 and IEC61394. It has become the designated grease purchased by well-known foreign companies in China. 3. Rust inhibitor for smooth steel wire and galvanized steel wire Smooth steel wire has two to three months before further processing by customers. In the atmospheric environment, it rusts and turns black, which not only reduces the product image, but also reduces the strength of the steel wire. The rust inhibitor forms a molecular rust-proof film on the surface of the steel wire, consuming 0.3 kg per ton of wire, applying it online, without adding any process, and at a low cost, achieving the purpose of a rust-proof period of more than four months. This rust inhibitor does not affect the next processing, electroplating, and painting process of the product. Galvanized steel wire will grow hair and white rust in a humid environment, which directly affects the product image and sales. The rust inhibitor for galvanized steel wire can effectively prevent white rust and maintain the silver luster of the metal. After the dry film, it has strong water resistance, high and low temperature stability, good metal adhesion, and online application without adding any process. It consumes 0.5 kg per ton, and the rust-proof cost is low. 4. Anti-rust lubricating grease for port machinery wire rope Port machinery wire ropes work at high intensity and high load, and have high standards for the strength and life of the wire ropes. It is even more important to choose excellent grease. IRIS-655, IRIS-255, and IRIS-200 are comparable to imported products in quality, and have been produced, used, and verified by many domestic companies for many years. The product has the characteristics of high dropping point, strong adhesion and good anti-rust lubricity.

The elasticity of stainless steel wire rope refers to the difficulty of elastic deformation under the action of external force. The stronger the elastic performance, the greater the elastic deformation stress generated by the stainless steel wire rope. During the use of stainless steel wire rope, the elasticity may decrease, and the rope body will undergo certain changes, which will have a certain impact on its own formation. Specifically: 1. The diameter of the rope body of the stainless steel wire rope will decrease. 2. The lay pitch of the stainless steel wire rope, that is, the straight-line distance between the starting point and the end point of the stainless steel wire inside the rope body rotating around the strand core or the strand, will be elongated. 3. Because the various parts of the stainless steel wire rope body are pressed against each other, there will be a lack of gaps between the stainless steel wires and between the strands. 4. Fine brown powder will appear in the concave part of the strand. The possibility of wire breakage and rope body breakage of the stainless steel wire rope will be greatly increased. Although the reduction in elasticity will not immediately produce adverse consequences, due to the decrease in the bending performance of the stainless steel wire rope and the decrease in diameter, the wear between the internal stainless steel wires will be aggravated, and the possibility of wire breakage and rope body breakage of the stainless steel wire rope will be greatly increased. The possibility of wire breakage and rope body breakage will be greatly increased.

People who often use slings know that the sling series wire rope products will be "twisted" after being used for a period of time. The twisted wire rope cannot be used anymore, and it is necessary to "relax" immediately to restore the normal state of the wire rope. So what exactly caused the wire rope to twist together? The following editor of the wire rope manufacturer will give you a detailed introduction. In fact, the twisting of the wire rope is caused by abnormal lifting height. Generally speaking, the wire rope is constantly wound and loosened during lifting, and the pressure on the wire rope is constantly increasing, slowly lifting the heavy object. However, the lifting height of the wire rope should not be too high, otherwise the rotational internal force of the wire rope will gradually accumulate, causing the wire rope to rotate, and causing the multiple wire ropes connected to it to entangle with each other, forming a "twisted" state. For cranes with low lifting heights, due to the continuous winding and relaxation of the wire rope, this stress is released periodically and will not cause serious impact on the heavy objects. However, if the lifting height is too high, the rotational internal force of the wire rope will gradually accumulate. When it reaches a certain height strength, the wire rope will rotate. Since the upper end of the wire rope is wound on the drum, the rotation will drive the hook below to rotate in the air and make the multiple strands of wire rope connected to it entangled with each other, which is commonly known as the "twisted twist" phenomenon. Once this happens, the wire rope crane can no longer be used normally, and the wire rope is "released", that is, the wire rope is removed from the drum, straightened, and then rewound on the drum. In summary, if the wire rope you use is always tangled, you can appropriately lower the lifting height and reinstall the wire rope. Do not rashly use a tangled wire rope to avoid accidents.

Stainless steel wire rope is commonly used in modern life. It is very necessary to use this rope in some places where hoisting is required, because it can ensure the safety of construction, so it is very important to choose a stainless steel wire rope with excellent quality. The development of modern industrialization has made stainless steel wire rope more and more widely used. If you want to buy a good stainless steel wire rope, you must first understand some related components, especially the use on related electric locomotives is gradually rising. Some industries use nylon nets, but they are gradually replaced by some wire ropes. Good wire ropes are not easy to deform and break. In the future development of the industry, the field of wire ropes is constantly expanding, and the selection of wire ropes also has grades and standards. Therefore, it is normal for the external environment to be closed for a long time and the insurance premium is closed first. If damage occurs, it can be divided into four levels. If super damage occurs, it will affect the weight of the wire rope at this time, so it should be replaced immediately. After configuring a certain wire rope, it needs to be checked. Stainless steel wire ropes are prone to cutting and related cutting during use. When cutting and processing the light rope head of the current backbone break, a certain head should be selected. If the port is somewhat disintegrated and the wire head of the backbone line is exposed, it can be said that the treatment is killing two birds with one stone.

Overloading of stainless steel wire rope refers to the phenomenon that the weight of the lifting object exceeds the actual load-bearing capacity of the wire rope, resulting in wear and even breakage. The risk of overloading of stainless steel wire rope is very high. In order to reduce this risk, what are the preventive measures for overloading of stainless steel wire rope? The analysis is as follows. 1. Correctly select the safety factor and strive to reduce the impact of other loads on stainless steel wire rope except static load. For example, the bending load can be reduced by increasing the diameter and drum of the pulley, the dynamic load can be reduced, the operation level of the crane driver can be improved, the performance of the crane can be improved, and the friction resistance can be reduced by adjusting the shape of the pulley groove and adding lubricating oil. 2. Strictly abide by the safety operating procedures and eliminate artificial overloading. 3. Install a load indicator, overload limiter or alarm device on the crane to eliminate overloading. The above is a description of the causes of overloading of stainless steel wire rope and an introduction to preventive measures. The overloading phenomenon of wire rope is very dangerous. It will not only cause huge economic losses, but also may cause certain accidents. Therefore, we must read and understand the above content carefully. At the same time, you are also welcome to continue to pay attention to our product knowledge. If you have any needs, please call us for negotiation.

In our lives, wire rope is a kind of hoisting and lifting accessories that are often used. It plays a big role in life, and many construction operations cannot be separated from the participation of wire rope. So what factors affect the service life and price of wire rope? Here we will talk about the factors that affect the price of Wuhan wire rope. Before talking about the price of wire rope, let's first look at what factors affect the service life of wire rope. There are actually two factors that determine the service life of wire rope, namely production process factors and use factors. In the production process of wire rope, we need to ensure the quality of steel wire and twisting process. Only in this way can we ensure the quality of wire rope and extend the service life of wire rope. At the same time, in terms of use, it is necessary to avoid the occurrence of mechanical damage, which is manifested as wear, wire breakage, overload, rust and other phenomena. The main factors affecting the price of wire rope in the market are the quality of wire rope and the supply and storage of wire rope in the market. When the storage volume is high, the price of wire rope will drop accordingly, which is related to the market environment. There is also the quality of the wire rope. The price required for wire ropes of different qualities is also different. At the same time, the model of the wire rope is also a factor that causes the price of the wire rope to change. In daily work, we should try to avoid overweight operations when using wire ropes, because this will be dangerous. Each wire rope has its load-bearing capacity. When we lift or pull, we need to consider the force range of the wire rope to avoid wire breakage.

Do you know how to oil the wire rope? Since the wire rope will be used in some harsh environments, it will cause corrosion and wear of the wire rope over time. Therefore, it should be lubricated regularly during production and use, which can effectively extend the service life. First of all, we need to oil all aspects of the wire rope during the production process. One is the rope core oiling, which is a very important task in the production of wire ropes. Before oiling, the wire rope core should be carefully wiped dry and the oil content of the rope core should be increased as much as possible. We usually know that the higher the oil content of the wire rope core, the better. Such a rope core can improve the lubrication conditions of the wire rope. There are generally two ways to oil the wire rope. One is to immerse the wire rope directly in the oil, and the other method is to use the vacuum oil immersion method. The former is relatively simple, but the inside of its coil is not easy to absorb oil, and the oil absorption is uneven. The vacuum oil immersion method is complicated, but the rope core coil can be immersed in oil, and its oil content is also very high. If we want to oil it later, we can only spray it on the surface or immerse it in the connection between the wire ropes. The surface of the wire rope is oiled by spraying or brushing. The method is to press the wound wire rope into the molten grease for oiling, but this oiling method is easy to cause oil leakage on the surface of the wire rope, and the internal wire rope is not well coated, which will affect the service life of the wire rope.

What is the impact of the service life of elevator wire rope? 1. The nature and number of broken wires The overall design of the lifting machinery does not allow the elevator wire rope to have an unlimited life. For 6-strand and 8-strand elevator wire ropes, broken wires mainly occur on the outer surface. Elevator wire ropes with multiple strands (typical multi-strand structure) are different. Most of the broken wires of this type of elevator wire rope occur inside, so it is an "invisible" break. 2. Wire breakage at the end of the rope When broken wires appear at the end of the rope or near the end of the rope, even if the number is small, it indicates that the part is under great force, which may be caused by incorrect installation of the rope end. The cause of the damage should be found out. If the rope length allows, cut off the broken wires and reinstall them reasonably. 3. Local aggregation of broken wires If the broken wires are close together to form a local aggregation, the elevator wire rope should be scrapped. If such broken wires are gathered in a rope length less than 6d or in any rope strand, the elevator wire rope should be discarded even if the number of broken wires is less than the listed value. 4. Increased wire breakage rate In some applications, fatigue is the main cause of elevator wire rope damage. Wire breakage begins to occur after a period of use, but the number of broken wires gradually increases and the time interval becomes shorter and shorter. In this case, in order to judge the increase rate of wire breakage, the increase in wire breakage should be carefully checked and recorded. This "rule" can be used to determine the future scrap date of the elevator wire rope. 5. Strand breakage If the entire strand is broken, the elevator wire rope should be discarded.

We are already familiar with some basic knowledge of slings, but these cannot be fully summarized, so there are still many knowledge points waiting for us to explore.   1. Procurement and self-production 1. When purchasing slings, you must purchase qualified products with safety certificates, and must not use unqualified products. 2. If the slings are homemade, they should meet the quality requirements stipulated by the state and the industry, and their technical indicators should not be lower than the national and professional standards. 2. Use 1. The user should be very familiar with the contents of the slings. If they are not familiar, they should not operate rashly to prevent danger. 2. The selected slings should meet or adapt to the appearance characteristics and requirements of the workpiece to be hoisted. If they do not meet or adapt, they must not be used. 3. Before using the slings, they should be carefully checked. Only after all the checks are correct can they be used, otherwise they cannot be used. 4. The rope points should be correctly selected before hanging, and the workpiece should be confirmed to be firmly tied before lifting. 5. The slings and accessories used cannot exceed the rated lifting weight. 6. During the operation, the slings and accessories must not be damaged. If necessary, some protective or protective measures can be taken. 7. After the slings are used, they should be returned to the storage place in time and should not be placed at will. III. Management 1. The user unit should establish a management system for slings for effective management. 2. The slings should be checked frequently during daily use. Once defects that affect safe use are found, they should be stopped immediately. 3. The user unit should conduct a comprehensive inspection of the slings every month, and evaluate their safety in accordance with safety technical requirements, and keep inspection records. IV. Storage When the slings and rigging are idle, they should be protected and stored. The storage place must meet the requirements and cannot be exposed to high temperature, corrosion, moisture and rust. Therefore, certain protective measures should be taken to prevent these phenomena from occurring.

(1) The size of the clamp should be suitable for the thickness of the wire rope. The inner clearance of the U-shaped ring should be 1 to 3 mm larger than the diameter of the wire rope. If the clearance is too large, it is difficult to clamp the rope.   (2) When using, tighten the U-shaped bolt until the wire rope is flattened by about 1/3. Since the wire rope deforms after being stressed, the rope clamp should be tightened for the second time after the wire rope is stressed to ensure the firmness of the joint. If you need to check whether the rope clamp slides after the wire rope is stressed, you can add a safety rope clamp. The safety rope clamp is installed about 500 mm away from the last rope clamp. After the rope head is released for a safety bend, it is clamped with the main rope. In this way, if the clamp slides, the safety bend will be straightened, which is easy to detect and reinforce at any time.   (3) The arrangement spacing between rope clamps is generally 6 to 7 times the diameter of the wire rope. Rope clamps should be arranged in sequence. The U-shaped ring part should be clamped on one side of the rope head and the pressure plate should be placed on one side of the main rope.   Uses of wire rope clips:   1. Carbon steel cast wire rope clips are often used for static tying and rope pulling, such as power and communication lines, bundling and fastening.   Forged wire rope clips are often used for lifting and lifting loads, such as various engineering lifting machinery, metallurgical and mining equipment, oil field derricks, port railway loading and unloading, forestry machinery, power equipment, aviation and maritime, land transportation, engineering rescue, salvage of sunken ships, lifting, hoisting and traction rigging of factories and mines.   Stainless steel wire rope clips are used in ship accessories, chemical plants, radiation and other environments because of their corrosion resistance and rust resistance.   2. Features: With the same strength as wire rope, safe to use, beautiful appearance and smooth transition, large safety load for lifting operations, can resist impact loads, and long service life.   3. Precautions for the use of wire rope clips: They cannot be used for a long time, should be checked and scrapped regularly, and cannot be used repeatedly.

Instructions for use of shackles Home ꄲ Instructions for use of shackles 1 Performance characteristics of shackles 1.1 The shackle body is made of high-quality carbon structure or alloy structure forged and heat-treated, with small size and high strength. 1.2 The test load of the shackle is 2 times the limit working load, and the breaking load is 4 times the limit working load. 2 Main uses and scope of application of shackles 2.1 Shackles can be used as end accessories of rigging and directly connected to the hoisted objects during lifting operations. 2.2 Shackles can be used between rigging and end accessories, and only serve as a connection. 2.3 When rigging is used with a beam, the shackle can be used to replace the lifting ring at the top of the rigging and connect with the ear plate under the beam, which is convenient for installation and removal. 2.4 Shackles are the most widely used connection tools in lifting operations, and are mainly used for connection parts that are frequently installed and removed during lifting. 2.5 Type D shackles are mainly used for single-leg rigging; Type B shackles are mainly used for multi-leg rigging. 2.6 BW and DW shackles are mainly used in situations where the rigging will not cause the pin to rotate; BX and DX shackles are mainly used in situations where the pin may rotate and in situations where they are installed for a long time.

(1) The size of the clamp should be suitable for the thickness of the wire rope. The inner clearance of the U-shaped ring should be 1 to 3 mm larger than the diameter of the wire rope. If the clearance is too large, it is difficult to clamp the rope.   (2) When using, tighten the U-shaped bolt until the wire rope is flattened by about 1/3. Since the wire rope deforms after being stressed, the rope clamp should be tightened for the second time after the wire rope is stressed to ensure the firmness of the joint. If you need to check whether the rope clamp slides after the wire rope is stressed, you can add a safety rope clamp. The safety rope clamp is installed about 500 mm away from the last rope clamp. After the rope head is released for a safety bend, it is clamped with the main rope. In this way, if the clamp slides, the safety bend will be straightened, which is easy to detect and reinforce at any time.   (3) The arrangement spacing between rope clamps is generally 6 to 7 times the diameter of the wire rope. Rope clamps should be arranged in sequence. The U-shaped ring part should be clamped on one side of the rope head and the pressure plate should be placed on one side of the main rope.   Uses of wire rope clips:   1. Carbon steel cast wire rope clips are often used for static tying and rope pulling, such as power and communication lines, bundling and fastening.   Forged wire rope clips are often used for lifting and lifting loads, such as various engineering lifting machinery, metallurgical and mining equipment, oil field derricks, port railway loading and unloading, forestry machinery, power equipment, aviation and maritime, land transportation, engineering rescue, salvage of sunken ships, lifting, hoisting and traction rigging of factories and mines.   Stainless steel wire rope clips are used in ship accessories, chemical plants, radiation and other environments because of their corrosion resistance and rust resistance.   2.
