Wire rope manufacturers produce their products in order to provide a high load capacity, versatile alternative to weaker ropes like manila rope or hemp rope. Wire rope products are used for a wide variety of motion transmission applications, among them: lifting, baling, tie down, hoisting, hauling, towing, mooring, anchoring, rigging, cargo control, guidance and counterbalance. They can also be used as railing, fencing and guardrailing.

Wire rope is a must-have for many heavy duty industrial applications. From mining to forestry to marine and beyond, there’s wire rope for almost every job. Some of the many industries in which wire rope is popular include: construction, agriculture, marine, industrial manufacturing, fitness, sports and recreation (plastic coated cables for outdoor playground equipment and sports equipment), electronics, theater (black powder coated cables for stage rigging), mining, gas and oil, transportation, security, healthcare and consumer goods.

Wire rope as we know it was invented just under 200 years ago, between 1831 and 1834. At that time, the goal was to create a rope strong enough to support work in the mines of the Harz Mountains. Invented by Wilhelm Albert, a German mining engineer, this wire rope consisted on four three-stranded wires. It was much stronger than older rope varieties, such as manila rope, hemp rope and metal chain rope.

While studying at Freiburg School of Mines, a man named L.D.B. Gordon visited the mines in the Harz Mountains, where he met Albert. After he left, Gordon wrote to his friend Robert Stirling Newall, urging him to create a machine for manufacturing wire ropes. Newall, of Dundee, Scotland, did just that, designing a wire rope machine that made wire ropes with four strands, consisting of four wires each. After Gordon returned to Dundee, he and Newall, along with Charles Liddell, formed R.S. Newall and Company. In 1840, Newall received a patent for “certain improvements in wire rope and the machinery for making such rope.”

In 1841, an American manufacturer named John A. Roebling began producing wire rope for suspension bridges. Soon after, another set of Americans, Josiah White and Erskine Hazard, started incorporating wire rope into coal mining and railroad projects, forming Lehigh Coal & Navigation Company (LC&N Co.). In 1848, wire rope from their wire rope factory in Mauch Chunk, Pennsylvania provided the lift cables needed to complete the Ashley Planes Project. This project sought to improve the performance and appearance of the freight railroad that ran through Ashley, Pennsylvania, by adding lift cables. This increased tourism and increased the railroad’s coal capacity. Before, cars took almost four hours to return; after, they took less than 20 minutes.

Wire rope likewise changed the landscape (again) in Germany, in 1874, when an engineering firm called Adolf Bleichert & Co. used wire rope to build Bi-cable aerial tramways. These allowed them to mine the Ruhr Valley. Several years later, they also used wire rope to build tramways for the German Imperial Army and the Wehrmacht. These tramways were wildly successful, opening up roads in Germany and all over Europe and the USA.

Since the 1800s, manufacturers and engineers have found ways to improve wire rope, through stronger materials and material treatments, such as galvanization, and different rope configurations. Today, wire rope makes possible many heavy industrial processes. It has become a necessity of the modern world.

Strands are made by tightly twisting or braiding individual wire together. One strand could have anywhere between two and several dozen wire filaments depending on the necessary strength, flexibility, and weight capacity.

One of the most dynamic elements of wire cables is the inner core. The strands are wrapped around the core, and it can be made of different metals, fibers, or even impregnated fiber materials. For heavy applications, cores are often made of a different strand of wire called an independent wire rope core (IWRC). An IWRC has a considerable amount of flexibility and it is still very strong. In fact, at least 7.5% of the strength increase in a wire rope can be attributed to an IWRC.

While they sometimes use other metals, like aluminum, nickel, copper, titanium, and even bronze for some applications, manufacturers primarily produce wire rope from steel. This is because steel is very strong and stretchable. Among the most common types they use are: galvanized wire, bright wire, stainless steel and cold drawn steel.

Of the wire rope steels, cold drawn carbon steel wire is most popular, although stainless steel wire rope is sometimes employed as well. Stainless steel rope is most popular for its anti-corrosive properties. Bright wire rope, a type of ungalvanized steel wire rope, is also popular. For added strength and durability, galvanized steel wire rope/galvanized steel cables are a very popular choice. Galvanized aircraft cable, for example, is always a must in aerospace.

When choosing or designing a custom wire rope for your application, suppliers consider factors such as: the environment in which the rope will function, required rust resistance, required flexibility, temperature resistance, required breaking strength and wire rope diameter. To accommodate your needs, manufacturers can do special things like: make your rope rotation resistant, color code your rope, or add a corrosion resistant coating. For instance, sometimes they specially treat and coat a cable with plastic or some other compound for added protection. This is particularly important to prevent fraying if the wire rope is often in motion on a pulley.

Manufacturers and distributors identify the differences in wire cable by listing the number of strands and the amount of wires per strand so that anyone that orders understand the strength of the cable. Sometimes they are also categorized by their length or pitch. Common examples of this include: 6 x 19, 6 x 25, 19 x 7, 7 x 19, 7 x 7, 6 x 26 and 6 x 36.

More complex wire rope identification codes connote information like core type, weight limit and more. Any additional hardware like connectors, fasteners, pulleys and fittings are usually listed in the same area to show varying strengths and degrees of fray prevention.

Cable wire rope is a heavy-duty wire rope. To give it its high strength, manufacturers construct it using several individual filaments that are twisted in strands and helically wrapped around the core. A very common example of cable wire rope is steel cable.

Spiral rope is made up an assemblage of wires with round or curved strands. The assemblage features at least one outer layer cord pointed in the opposite direction of the wire. The big advantage of spiral ropes is the fact that they block moisture, water and pollutants from entering the interior of the rope.

Similarly, stranded rope steel wire is made up of an assemblage of spirally wound strands. Unlike spiral rope, though, its wire patterns have crisscrossing layers. These layers create an exceptionally strong rope. Stranded rope may have one of three core material types: wire rope, wire strand or fiber.

Wire rope chain, like all chains, is made up of a series of links. Because it is not solid, wire rope chain is quite flexible. At the same time, it is prone to mechanical failure.

Wire rope slings are made from improved plow wire steel, a strong steel wire that offers superior return loop slings and better security. The plow wire steel also shields rope at its connection points, which extends its working life. Wire rope slings, in general, provide their applications with increased safety, capacity and performance. Wire rope sling is a rope category that encompasses a wide range of sub-products, such as permaloc rope sling, permaloc bridle slings and endless slings. These and other wire rope slings may be accompanied by a wide variety of sling terminations, such as thimbles, chokers and hooks.

Wire rope offers its user many advantages. First, design of even distribution of weight among strands makes it ideal for lifting extremely heavy loads. Second, wire rope is extremely durable and, when matched properly to the application, can withstand great stress and elements like corrosion and abrasion. In addition, it is very versatile. Its many iterations and the ways in which the rope can treated means that users can get rope custom fit for virtually any application.

Depending on the type of wire rope with which you are working and your application, you may want to invest in different accessories. Among these accessories are: wire rope clips, steel carabiners, fittings, fasteners and connections.

To ensure that your wire rope quality remains high, you must regularly inspect them for wear and degradation. The right wire rope should be selected for a particular use. Watch out for performance-impacting damage like: rust, fraying and kinks. To make sure that they stay in tip-top shape, you should also clean and lubricate them as needed. Check for this need as a part of your regular inspection.

Rope care is about more than inspection. It’s also about making an effort to use and store them properly every time you use them. For example, never exceed your rope’s rated load and breaking strength. Doing so will not only cause the weakening of your cable, but it may even cause immediate breakage. In addition, always store your wire rope cable in a dry and warm area, away from those elements that could cause premature rusting or other damage. Finally, always carefully wind your wire rope when you’re done with it, so as to avoid kinks. If you follow all these tips and treat your wire rope assemblies well, they will reward you with a long and productive service life.

Always make sure that you purchase wire rope that matches your industry and regional standards. Some of the most widely referenced standards organizations for wire rope include: ISO, ASTM International and OSHA. Talk over your specifications and application with your wire rope supplier to figure out what’s best for you.

A wire rope is a type of cable that includes several wire strands laced together to form a single wire. Generally, both the terms “wire” and “rope” are used interchangeably with “wire rope”; however, according to the technical definition, to be labeled a wire rope, the cable must have a thickness of at least 9.52 mm. As a versatile, high load capacity alternative to natural fiber ropes such as hemp and manila, wire rope provides motion transmission through nearly all angles, tie down, counterbalance, guidance, control, or lift.

Modern wire rope was invented by Wilhelm Albert, a German mining engineer, between 1831 and 1834. He developed them in order for work in the mines in the Harz Mountains. This rope replaced weaker natural fiber ropes, like hemp rope and manila rope, and weaker metal ropes, like chain rope.

Albert’s rope was constructed of four three-stranded wires. In 1840, a Scot named Robert Stirling Newall improved upon this model. A year later in the United States, American manufacturer John A. Roebling started producing wire rope, aimed at his vision of suspension bridges. From there, other interested Americans, such as Erskine Hazard and Josiah White, used wire rope in railroad and coal mining applications. They also applied their wire rope techniques to provide lift ropes for something called the Ashley Planes project, which allowed for better transportation and increased tourism in the area.

Approximately twenty-five years later, back in Germany in 1874, the engineering firm Adolf Bleichert & Co. was founded. They used wire rope to build bicable aerial tramways for mining the Ruhr Valley. Years later they built tramways for both the Wehrmacht and the German Imperial Army. Their wire rope systems spread all across Europe, and then migrated to the USA, concentrating at Trenton Iron Works in New Jersey.

Over the years, engineers and manufacturers have created materials of all kinds to make wire rope stronger. Such materials include stainless steel, plow steel, bright wire, galvanized steel, wire rope steel, electric wire, and more. Today, wire rope is a staple in most heavy industrial processes. Wherever heavy duty lifting is required, wire rope is there to facilitate.

Wire rope is strong, durable, and versatile. Even the heaviest industrial loads may be lifted with a well-made wire rope because the weight is distributed evenly among constituent strands.

There are three basic elements of which wire ropes are composed: wire filaments, strands, and cores. Manufacturers make wire rope by taking the filaments, twisting or braiding them together into strands, and then helically winding them around a core. Because of this multiple strand configuration, wire rope is also often referred to as stranded wire.

The first component, the filaments, are cold drawn rods of metal materials of varying, but relatively small diameter. The second component, the strands, can individually consist of as few as two or as many as several dozen filaments. The last component, the core, is the central element around which strands are wrapped; wire rope cores maintain a considerable amount of flexibility, while increasing strength by at least 7.5% over the strength of fiber core wire ropes.

The helical winding of the strands around the core is known as the lay. Ropes may be right hand lay, twisting strands clockwise, or they may be left hand lay, twisting strands counter-clockwise. In an ordinary lay, the individual strands are twisted in the opposite direction of the lay of the entire rope of strands to increase tension and to prevent the rope from coming unwound. Though this is most common Lang"s lay has both the strands and the rope twisted in the same direction while alternate lays, as the name suggests alternate between ordinary and Lang style lays. While alternative rope designs are available, the helical core design is often favored, as it allows a wire cable to hold a lot of weight while remaining ductile.

There are many design aspects that wire rope manufacturers consider when they are creating custom wire rope assemblies. These include: strand gauge (varies based on application strength, flexibility, and wear resistance requirements), wire rope fittings (for connecting other cables), lay, splices, and special coatings. Specially treated steel cable and plastic coated cables, for instance, are common to many application specific variations of wire rope such as push pull cable assemblies used in transferring motion between two points.

Suppliers typically identify wire cable by listing both the number of strands and the amount of wires per strand respectively, though stranded cable may alternatively be measured by their lay and length or pitch. For example, a door-retaining lanyard wire rope is identified by its 7 x 7 construction, and wire rope used for guying purposes is identified by its 1 x 19 construction. The most common types are 6 x 19, 6 x 25, 19 x 7, 7 x 7, 7 x 19, 6 x 26, and 6 x 36.

An ungalvanized steel wire rope variety. This uncoated wire rope can also be designed to resist spinning or rotating while holding a load; this is known as rotation resistant bright wire rope.

Also called a coiled wire rope, a coiled cable is a rope made from bundles of small metal wires, which are then twisted into a coil. Wire rope and cable can come in a huge variety of forms, but coiled cables specifically provide the benefits of easy storage and tidiness. Unlike other wire ropes, coiled cables do not require a spool for storage. Because it has been coiled, the cable will automatically retract into its spring-like shape when it is not in use, making it incredibly easy to handle.

A type of high strength rope, made of several individual filaments. These filaments are twisted into strands and helically wrapped around a core. One of the most common types of wire rope cable is steel cable.

Wire rope made not as one solid piece, but as a piece made up of a series of metal links. Wire rope chain is flexible and strong, but it is more prone to mechanical failure than wire rope.

Push pull cables and controls are a particular type of control cable designed for the positive and precise transmission of mechanical motion within a given system. Unlike their counterpart pull-pull cables, these wire rope assemblies offer multidirectional control. Additionally, their flexibility allows for easy routing, making them popular in a number of industrial and commercial applications.

Iron and steel are the two most common materials used in producing wire ropes. A steel wire is normally made from non-alloy carbon steel that offers a very high strength and can support extreme stretchable forces. For even more strength and durability, manufacturers can make stainless steel wire rope or galvanized steel wire rope. The latter two are good for applications like rigging and hoisting.

Technically, spiral ropes are curved or round strands with an assemblage of wires. This gathering of wires has at least one cord situated in the opposite direction of the wire in the outer layer of the rope. The most important trait of this rope is that all the wires included are round. The biggest benefit of this category of rope is that it does not allow the entrance of pollutants, water, or moisture.

Contain an assemblage of strands placed spirally around a core. Stranded rope steel wire patterns have different layers that cross each other to form an even stronger cable or rope. Stranded ropes contain one of three types of core: a fiber core, a wire strand core, or a wire rope core.

Provide an added level of security to a manufacturing production application. Wire rope slings are made from improved plow steel wire ropes that, apart from offering added security, also provide superior return loop slings. Plow steel wire ropes improve the life of a mechanism by shielding the rope at its connection points. The key objective of wire rope slings is to enhance the safety of an application while increasing its capacity and performance. Rope slings are also available in various sling termination options, such as hook type, chokers, and thimbles.

The eye in this rope sling is made using the Flemish Splice method. Just like a typical sling, a Permaloc rope sling improves safety and provides reverse strength meaning that the uprightness of the eye does not depend on the sleeves of the metal or alloy. Additionally, permaloc rope slings offer an abrasion resistance feature that makes them long lasting.

These slings have all the features that most other slings offer. However, compared to their counterparts, Permaloc bridle slings provide better load control, wire rope resistant crushing, robust hooks and links that work for a longer duration, and help save on maintenance requirements.

Manufacturers produce wire rope for many different reasons; from cranes to playground swings, wire ropes have something for everyone. Among the many applications of wire rope are hoisting, hauling, tie down, cargo control, baling, rigging, anchoring, mooring, and towing. They can also serve as fencing, guardrails, and cable railing, among other products.

Some of the industries that make use of wire rope include industrial manufacturing, construction, marine, gas and oil, mining, healthcare, consumer goods, and transportation. Others include the fitness industry, which uses plastic coated cable products in weight machines, the theater industry, which uses black powder coated cables for stage rigging, the recreation industry, which uses plastic coated cables for outdoor playground equipment, and the electronics industry, which uses miniature wire rope for many types of electronic equipment and communications devices.

Wire ropes are typically made from cold drawn steel wire, stainless steel wire, or galvanized wire. They may also be made from a wide variety of less popular metals, including aluminum, nickel alloy, bronze, copper, and titanium. However, nearly all wire ropes, including control cables, are made from strands of cold drawn carbon steel wires. Stainless steel rope and cables are subbed in for highly corrosive environments. Galvanized cables and galvanized wire rope are popular for their increased strength and durability; these qualities are important to specialized ropes like galvanized aircraft cable.

A core may be composed of metal, fiber or impregnated fiber materials depending on the intended application. Cores may also be another strand of wire called an independent wire rope core (IWRC).

Wire rope, depending on its application, is subject to many standard requirements. Among the most common of these are the standards detailed by OSHA, ASTM International, and ISO. Per your application and industry, you’ll likely have others you need to consider. To get a full list, talk to your service provider.

To determine the safety factor, which is a margin of security against risks, the first step involves knowing the type of load that the rope will be subjected to. The load must consider the shock loads and blowing wind effects. The safety factor is characterized in ratios; typical are 4:1 and 5:1. If a ratio is 5:1, then the tensile strength of a wire rope must be five times of the load it will be subjected to. In some applications, the ratios can go up to 10:1.

By weighing all these factors carefully, the wire rope that you will buy will be safe to use and last considerably. For the best advice and guidance, though, don’t go it alone! Find a great wire rope supplier that you can trust. You’ll know you’ve found the right supplier for you when you talk to one that can not only fulfill your requirements, but shows that they are excited to go the extra mile for you. For a company like this, browse the list near the top of the page.

As the cables play an integral role in the safety of many operations and structures, careful analysis of a wire rope and all of its capabilities and features is vital. Important qualities and physical specifications you must consider include wire rope diameter, breaking strength, resistance to corrosion, difficulty of flattening or crushing, bendability, and average lifespan.

Each of the aforementioned considerations should be compatible with the specific application for which the rope is intended as well as the environment in which such operations are undertaken. Temperature and corrosive environments often require specially coated wire ropes with increased durability.

When you use your industrial wire rope, the first thing to remember is to not exceed your rope’s rated load and breaking strength. If you do not stay within these parameters, you risk causing your rope to weaken or even break.

Rust, kinks, fraying and even carefully performed splicing will all have an impact on the performance of wire ropes. To maintain the integrity of your wire rope assembly, you need to inspect them regularly and clean and lubricate them as needed. In addition, you need to store them out of the wet and cold as much as possible. Also wrap them up properly, so they are not kinked.

Steel that is designed for applications, which require greater safety features with no increase in diameter size and the highest resistance to abrasive wear. This steel is fifteen percent stronger than Improved Plow Steel, and the tensile strength of this grade ranges from 280,000 to 340,000 psi.

A high-carbon steel having a tensile strength of approximately 260,000 psi that is roughly fifteen percent stronger than Plow Steel. Most commercial wires are made from IPS.

A low carbon steel wire of approximately 10,000 psi, which is pliable and capable of repeated stresses from bending around small sheaves. This grade is effective for tillers, guys and sash ropes.

The manner in which the wires are helically wound to form rope. Lay refers specifically to the direction of the helical path of the strands in a wire rope; for example, if the helix of the strands are like the threads of a right-hand screw, the lay is known as a right lay, or right-hand, but if the strands go to the left, it is a left lay, or left-hand.

A classification of wire rope according to its breaking strength. The rank of grades according to increasing breaking strengths is as follows: Iron, Traction, Mild Plow Steel, Plow Steel, Improved Steel, Extra Improved Steel.

The act of fastening a termination to a wire rope through physical deformation of the termination about the rope via a hydraulic press or hammering. The strength is one hundred percent of the wire rope rating.

A grade of rope material that has a tensile strength range of 180,000 to 190,000 psi. Traction steel has great resistance to bending fatigue with a minimum of abrasive force on sheaves and drums, which contributes to its long use in elevators, from which the steel gets its name.

It is composed of wire strands that are braided together. Wire braid is similar to stranded wire. The difference between the two is the fact that stranded wire features strands that are bundled together, rather than braided.

Essential parts of cable assemblies, wire rope assemblies and wire rope slings that assist spliced or swaged rope ends in connecting to other cables and keeping cables and rope from unraveling.

A wire rope cable assembly is a metallic rope consisting of bundles of twisted, spiraled, or bonded wires. While the terms wire rope and cable are often used interchangeably, cables are typically designated as smaller diameter wire ropes, specifically wire ropes with a diameter less than 3/8 inch. Therefore, wire rope cable assemblies are typically utilized for lighter duty applications.

Or cable assemblies, are cables which are composed of many spiraled bundles of wire. These cables are used to support hanging objects, connect objects, pull or lift objects, secure items, and much more.

Wire ropes are a common tool, often considered a machine, and have many applications. Each type of rope is used for specific tasks and varies in strength, flexibility, abrasion resistance, etc.

Galvanized wire rope is a steel write rope with a layer of zinc, which helps in preventing the ropes from corrosion and rusting. Mostly suitable for construction in wet places, these wire ropes prevent the deposition of dust in the inner steel.

Stainless steel wires are very common in industrial and commercial industries and offer a decent degree of protection against corrosion and rust. Most often used in indoor applications, stainless steel will not do good in outdoors as it does in indoor usage.

With time, galvanized wire rope coatings will wear off, but may still be resistant to chemicals or rust. Stainless steel wire rope is highly resistant to corrosion, or harsh chemicals.

Stainless steel wire rope is made using standard alloy used in ropes or cables, whereas, galvanized wire ropes are steel wires that have gone through the galvanization process.

Galvanized wire ropes are suitable for marine locations and constructions around them. Objects or constructions around these locations are exposed to wetness and dampness at all times.

Wire ropes have been widely used in the lifting, luffing, and trolley traction mechanisms of container cranes (hereinafter referred to as quay cranes). It is the main flexible component in the use of container quay cranes. It has the advantages of large carrying capacity, good flexibility, smooth transmission, impact resistance, no noise during high-speed movement, safety and reliability. With the development of container quay crane manufacturing technology, the current development direction of quay cranes is large-scale, high-speed, and high-efficiency. The reach of the quay crane is getting longer and longer, and the lifting load is getting larger and larger. In the long-distance transmission of wire rope, It also showed deficiencies such as sagging caused by its own weight, and large bounce at the moment of starting. How to choose and use the appropriate wire rope has become a problem that the quay crane management workers must study.

A steel wire rope is a rope made of multiple steel wires twisted according to certain rules. It is composed of a rope-making steel wire, a rope core, and rope grease. The main components of steel wire rope are: twisting method, contact state, number and shape of rope strands, rope core material, etc.

There are currently three types of single-twist steel wire ropes, double-twist steel wire ropes, and three-twist steel wire ropes. Among them, single-twist and double-twist steel wire ropes are common.

1.1.1 Single-twist steel wire rope: A rope made of several steel wires at one time, which is characterized by high rigidity of the rope and poor winding performance.

1.1.2 Double-twisted steel wire rope: Double-twisted steel wire rope can also be composed of two structural forms: co-twisting (sequential winding) and alternating twisting (interleaving). The same direction twisted steel wire rope has good flexibility, low abrasion and long service life, but it is easy to loosen and twist and knot. Generally, it is only used in the situation where there is a rigid guide rail or the rope end will not rotate freely. The twisting direction of the strands in the alternating twisted steel wire rope is opposite to that of the rope, and it is not easy to twist loosely, but the rope is slightly more rigid and has a shorter service life. Most of the container quay cranes use alternately twisted steel wire ropes.

There are three types of contact states between adjacent layers of steel wires in the steel wire rope strand: point contact, line contact, and surface contact.

1.2.1 Point contact: The lay lengths of the steel wires in each layer of the strand are different, and they cross each other. The steel wires at each intersection point are in point contact, so the contact stress is high, and there is a secondary bending stress. The linearity of the point contact rope is better, but the resistance to bending fatigue is poor, and the service life is short. It has been gradually replaced by the line contact rope.

1.2.2 Line contact: Each layer of steel wire in the strand is twisted in parallel over the entire length, and the outer layer of steel wire is located in the groove formed between the inner layer of steel wires, and is in line contact with it. The contact stress is low, the bending fatigue resistance is good, the structure is relatively compact, the utilization factor of the metal section is high, and the service life is on average 1-2 times higher than that of the point contact rope. Commonly used on quayside cranes are 6xwS (31), 6XWS (36) and so on.

1.2.3 Surface contact: The shape of the steel wire in the strand is formed by a special extrusion or drawing method, and they are in surface contact with each other. Its advantages are: it is not prone to wire breakage, corrosion resistance and wear resistance are good, and it can withstand large lateral forces, but its flexibility is poor. It is not suitable for installation in places with reverse winding or small pulleys.

There are 6 strands, 8 strands, 9 strands, etc. of wire rope strands commonly used in quay cranes, among which 6 strands are the most common. The more the number of outer strands, the better the contact between the steel wire rope and the pulley and drum rope groove, and the longer the service life. The metal filling rate of the 8-strand rope is lower, and its breaking force is about 10% lower than that of the 6-strand rope with the same diameter, but its wear resistance and life are better than that of the 6-strand rope. Currently, many users use it in the quay crane lifting system. Strand rope structure.

1.4.2 Steel wire rope core (1wRC): Steel wire rope or rope strand is used as the rope core. This type of steel wire rope has high strength, can withstand higher pressure and higher working temperature, has poor oil storage performance, and has poor flexibility and elasticity.

In recent years, foreign countries have designed and produced a new type of plastic-filled steel wire rope, which is made by twisting the steel core part with special plastic and then twisting the outer strands of steel wire. This kind of wire rope can knead the advantages of fiber core and steel core wire rope, reducing internal friction, at the same time, the structure is more stable, the internal lubrication and anti-corrosion performance is significantly improved, and the metal surface area is not reduced while maintaining the interception load.

The difference in quality between imported steel wire rope and domestic steel wire rope is mainly reflected in the manufacturing process of steel wire rope. Raw material processing, manufacturing technology, manufacturing equipment, design concepts, technical standards and many other technical aspects are far behind the world"s technologically advanced countries, resulting in the quality of domestic steel wire rope. Problems such as short life cycle and low technical quality have appeared. It is specifically manifested in the following aspects:

Wire rod is the main raw material for manufacturing steel wire rope, and its quality directly affects the quality of steel wire rope. Improving the quality and stability of the wire rod is the key to improving the quality and stability of the wire rope.

The quality of domestic wire rods and the quality of wire rods in developed countries in the world are mainly due to the fluctuations in the internal components of the wire rods, the segregation of components, the low purity, the existence of undesirable structures (low degree of sorbite), porosity in the center, shrinkage cavities, cracks, etc. Inclusions and so on. Surface defects of wire rod include surface cracks, surface irregularities, and diameter fluctuations. The fluctuation and uniformity of the carbon content in the wire rod and the presence of harmful components. These have caused the performance fluctuation of the domestic steel wire to be greater than the world advanced level, which is the main factor causing the unstable fluctuation of the fatigue performance of the domestic steel wire rope. At present, the quality of domestic Baosteel wire rod is relatively stable in China. If domestic wire rope is selected, it should be agreed with the manufacturer to use wire rod from a designated steel mill to prevent the quality of the wire rod from affecting the service life of the wire rope.

The fluctuation of the steel wire diameter has a certain impact on the structure of the steel wire rope. From the perspective of steel wire manufacturing technical standards, domestic standards have a wider range of fluctuations than those of advanced countries in the world.

The precision control of steel wire diameter in steel wire ropes in advanced countries in the world is very strict, generally between 0.01mm and 0.02mm. However, the precision control range of domestic steel wire diameter is relatively large, generally within ±0.03mm.Even if the steel wire fluctuates within the specified range of the standard, it may cause complicated force on the steel wire rope, damage the steel wire, and cause the wire rope to break early.

There is a big difference between the heat treatment process technology control of steel wire ropes in China and the international advanced level, which is also one of the reasons for the reduction of the service life of steel wire ropes.

The raw materials for the manufacture of steel wire ropes first undergo a heat treatment process. The heat treatment process applies a certain temperature heating to the raw materials used in the manufacture of steel wire ropes, and is quenched in the lead liquid medium to obtain a good metallographic structure-sorbite. The factors that affect the sorbite transformation during the heat treatment are mainly the furnace temperature of the heating furnace, the wire temperature of the steel wire, and the lead temperature of the lead pot. These temperature changes directly affect the Soxhlet content of the steel wire. Due to the high level of automatic control of steel wire heat treatment in foreign countries, the furnace temperature, wire temperature, and lead temperature are generally controlled within 5 degrees Celsius, while domestic heat treatment is generally at 10 degrees Celsius or higher. Fatigue and broken wires have a certain effect.

The foreign advanced level of wire production equipment generally uses advanced linear wire drawing machines. Its advantage is to reduce the torsion of the wire during the drawing process, and the cooling performance of this wire drawing machine is good, which has a greater effect on improving the performance of the wire. . Many domestic steel wire rope manufacturers use wire drawing machines for wire production equipment. During the drawing process, the steel wire has an axial torsion phenomenon. This axial torsion phenomenon has a greater impact on high-strength steel wires. In addition, the multi-thread drawing machine has many guide wheels and many twists of the steel wire, which loses the fatigue resistance of the rope-making steel wire.

There are various advanced wire rope structures abroad, and they are dominated by multi-wire contact, multi-strand (above six strands), pressed surface and plastic-coated wire rope. The optimized steel wire rope structure has a longer life span than ordinary steel wire ropes. For example, the life of the wire rope after pressing is about 1.5-2 times longer than that of the wire rope without pressing, and the life of the line contact wire rope is 1.5-2 times that of the point contact wire rope. In the structural design of foreign steel wire ropes, the gap value between the strands in the rope and the gap value between the steel wires in the strands and the steel wires are considered, so that the steel wire rope is under stress, between the strands and the strands of the wire rope, and between the steel wires and the steel wires. The contact stress between each other is the most reasonable to avoid the early wire breakage of the wire rope due to the concentration of contact stress between the steel wire and the steel wire.

The structure of domestic steel wire ropes is relatively simple, mainly point-contact steel wire ropes, with less line contact, multiple strands, pressing surface and plastic coating. In the structural design, the gap value between the strands in the rope and the gap between the steel wires in the strands and the gap between the steel wires in the strands are not fully considered. The contact stress between the steel wire and the steel wire in the strand is unreasonable, resulting in the concentration of the contact stress between the steel wire and the steel wire, which leads to the early wire breakage of the wire rope. At present, the precise design of steel wire rope structure has attracted the attention of various domestic manufacturers, and the gap in the design of steel wire rope structure is gradually narrowing.

Foreign steel wire rope greases are researched by specialized institutions, and special greases are manufactured for different purposes and occasions. For example, a foreign company uses steel wire rope with many corrosive components, and the steel wire rope is generally used for about half a year. After the expert analyzes the use environment of the wire rope, select the grease suitable for the environment, and the service life of the wire rope can reach more than 4 years. However, a famous domestic steel wire rope manufacturer once provided steel wire ropes to users in the north. The steel wire ropes did not use low-temperature resistant lubricants, which led to the failure of the grease accumulation and abnormal breakage of the steel wire rope when encountered in severe cold weather. Domestic steel wire rope manufacturers do not carefully select the grease used for steel wire ropes, which is also one of the reasons for the unstable quality of domestic steel wire ropes.

At present, there are many types of wire ropes on the market. Choosing the right wire rope is very important for safe production, cost control, and improving the efficiency of quay crane equipment. Based on these considerations, the role of value engineering in management can be highlighted, and reasonable cost performance can be satisfied. Various needs in business management.

Based on the quay crane equipment of the company where the author works, the main form of failure of the hoisting wire rope in the past was broken wire and fold, the diameter of the wire rope was worn less than 4%, and the core rope was corroded and broken wire. In response to these circumstances, it was decided to use the 8-strand surface contact steel core steel wire rope with imported new triangular plastic filling and wear-resistant technology to achieve mechanical isolation between the main strand and the main strand, and the steel core and the outer strand to isolate, buffer, reduce wear, and reduce vibration. Anti-corrosion effect, but also improve the internal lubrication performance, prolong the service life, and reduce maintenance costs.

·Delivery size: the actual diameter of the steel wire rope is 29.6mm, the actual average diameter of the steel wire is 1.1mm; the main rope lay length is 165mm

Since the author’s company put this type of steel wire rope into use in 6 heavy-duty bridge cranes in June 2004, the volume of the operating box has basically been in the range of 263,000 to 286,000 TEU, and the diameter of the steel wire after wear is 27.0-27.6mm, and the internal and external lubrication conditions are good.

For container terminal companies with relatively idle quay crane operations, if the quay crane has a sufficient maintenance cycle to complete the replacement of the wire rope, the above-mentioned N and C effects can be ignored, and it is wise to choose domestic wire rope.

In stricter senses, the term wire rope refers to a diameter larger than 9.5 mm (3⁄8 in), with smaller gauges designated cable or cords.wrought iron wires were used, but today steel is the main material used for wire ropes.

Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure. While flaws in chain links or solid steel bars can lead to catastrophic failure, flaws in the wires making up a steel cable are less critical as the other wires easily take up the load. While friction between the individual wires and strands causes wear over the life of the rope, it also helps to compensate for minor failures in the short run.

Wire ropes were developed starting with mining hoist applications in the 1830s. Wire ropes are used dynamically for lifting and hoisting in cranes and elevators, and for transmission of mechanical power. Wire rope is also used to transmit force in mechanisms, such as a Bowden cable or the control surfaces of an airplane connected to levers and pedals in the cockpit. Only aircraft cables have WSC (wire strand core). Also, aircraft cables are available in smaller diameters than wire rope. For example, aircraft cables are available in 1.2 mm (3⁄64 in) diameter while most wire ropes begin at a 6.4 mm (1⁄4 in) diameter.suspension bridges or as guy wires to support towers. An aerial tramway relies on wire rope to support and move cargo overhead.

Modern wire rope was invented by the German mining engineer Wilhelm Albert in the years between 1831 and 1834 for use in mining in the Harz Mountains in Clausthal, Lower Saxony, Germany.chains, such as had been used before.

Wilhelm Albert"s first ropes consisted of three strands consisting of four wires each. In 1840, Scotsman Robert Stirling Newall improved the process further.John A. Roebling, starting in 1841suspension bridge building. Roebling introduced a number of innovations in the design, materials and manufacture of wire rope. Ever with an ear to technology developments in mining and railroading, Josiah White and Erskine Hazard, principal ownersLehigh Coal & Navigation Company (LC&N Co.) — as they had with the first blast furnaces in the Lehigh Valley — built a Wire Rope factory in Mauch Chunk,Pennsylvania in 1848, which provided lift cables for the Ashley Planes project, then the back track planes of the Summit Hill & Mauch Chunk Railroad, improving its attractiveness as a premier tourism destination, and vastly improving the throughput of the coal capacity since return of cars dropped from nearly four hours to less than 20 minutes. The decades were witness to a burgeoning increase in deep shaft mining in both Europe and North America as surface mineral deposits were exhausted and miners had to chase layers along inclined layers. The era was early in railroad development and steam engines lacked sufficient tractive effort to climb steep slopes, so incline plane railways were common. This pushed development of cable hoists rapidly in the United States as surface deposits in the Anthracite Coal Region north and south dove deeper every year, and even the rich deposits in the Panther Creek Valley required LC&N Co. to drive their first shafts into lower slopes beginning Lansford and its Schuylkill County twin-town Coaldale.

The German engineering firm of Adolf Bleichert & Co. was founded in 1874 and began to build bicable aerial tramways for mining in the Ruhr Valley. With important patents, and dozens of working systems in Europe, Bleichert dominated the global industry, later licensing its designs and manufacturing techniques to Trenton Iron Works, New Jersey, USA which built systems across America. Adolf Bleichert & Co. went on to build hundreds of aerial tramways around the world: from Alaska to Argentina, Australia and Spitsbergen. The Bleichert company also built hundreds of aerial tramways for both the Imperial German Army and the Wehrmacht.

In the last half of the 19th century, wire rope systems were used as a means of transmitting mechanical powercable cars. Wire rope systems cost one-tenth as much and had lower friction losses than line shafts. Because of these advantages, wire rope systems were used to transmit power for a distance of a few miles or kilometers.

Steel wires for wire ropes are normally made of non-alloy carbon steel with a carbon content of 0.4 to 0.95%. The very high strength of the rope wires enables wire ropes to support large tensile forces and to run over sheaves with relatively small diameters.

In the mostly used parallel lay strands, the lay length of all the wire layers is equal and the wires of any two superimposed layers are parallel, resulting in linear contact. The wire of the outer layer is supported by two wires of the inner layer. These wires are neighbors along the whole length of the strand. Parallel lay strands are made in one operation. The endurance of wire ropes with this kind of strand is always much greater than of those (seldom used) with cross lay strands. Parallel lay strands with two wire layers have the construction Filler, Seale or Warrington.

In principle, spiral ropes are round strands as they have an assembly of layers of wires laid helically over a centre with at least one layer of wires being laid in the opposite direction to that of the outer layer. Spiral ropes can be dimensioned in such a way that they are non-rotating which means that under tension the rope torque is nearly zero. The open spiral rope consists only of round wires. The half-locked coil rope and the full-locked coil rope always have a centre made of round wires. The locked coil ropes have one or more outer layers of profile wires. They have the advantage that their construction prevents the penetration of dirt and water to a greater extent and it also protects them from loss of lubricant. In addition, they have one further very important advantage as the ends of a broken outer wire cannot leave the rope if it has the proper dimensions.

Stranded ropes are an assembly of several strands laid helically in one or more layers around a core. This core can be one of three types. The first is a fiber core, made up of synthetic material or natural fibers like sisal. Synthetic fibers are stronger and more uniform but cannot absorb much lubricant. Natural fibers can absorb up to 15% of their weight in lubricant and so protect the inner wires much better from corrosion than synthetic fibers do. Fiber cores are the most flexible and elastic, but have the downside of getting crushed easily. The second type, wire strand core, is made up of one additional strand of wire, and is typically used for suspension. The third type is independent wire rope core (IWRC), which is the most durable in all types of environments.ordinary lay rope if the lay direction of the wires in the outer strands is in the opposite direction to the lay of the outer strands themselves. If both the wires in the outer strands and the outer strands themselves have the same lay direction, the rope is called a lang lay rope (from Dutch langslag contrary to kruisslag,Regular lay means the individual wires were wrapped around the centers in one direction and the strands were wrapped around the core in the opposite direction.

Multi-strand ropes are all more or less resistant to rotation and have at least two layers of strands laid helically around a centre. The direction of the outer strands is opposite to that of the underlying strand layers. Ropes with three strand layers can be nearly non-rotating. Ropes with two strand layers are mostly only low-rotating.

Stationary ropes, stay ropes (spiral ropes, mostly full-locked) have to carry tensile forces and are therefore mainly loaded by static and fluctuating tensile stresses. Ropes used for suspension are often called cables.

Track ropes (full locked ropes) have to act as rails for the rollers of cabins or other loads in aerial ropeways and cable cranes. In contrast to running ropes, track ropes do not take on the curvature of the rollers. Under the roller force, a so-called free bending radius of the rope occurs. This radius increases (and the bending stresses decrease) with the tensile force and decreases with the roller force.

Wire rope slings (stranded ropes) are used to harness various kinds of goods. These slings are stressed by the tensile forces but first of all by bending stresses when bent over the more or less sharp edges of the goods.

Technical regulations apply to the design of rope drives for cranes, elevators, rope ways and mining installations. Factors that are considered in design include:

Donandt force (yielding tensile force for a given bending diameter ratio D/d) - strict limit. The nominal rope tensile force S must be smaller than the Donandt force SD1.

The wire ropes are stressed by fluctuating forces, by wear, by corrosion and in seldom cases by extreme forces. The rope life is finite and the safety is only ensured by inspection for the detection of wire breaks on a reference rope length, of cross-section loss, as well as other failures so that the wire rope can be replaced before a dangerous situation occurs. Installations should be designed to facilitate the inspection of the wire ropes.

Lifting installations for passenger transportation require that a combination of several methods should be used to prevent a car from plunging downwards. Elevators must have redundant bearing ropes and a safety gear. Ropeways and mine hoistings must be permanently supervised by a responsible manager and the rope must be inspected by a magnetic method capable of detecting inner wire breaks.

The end of a wire rope tends to fray readily, and cannot be easily connected to plant and equipment. There are different ways of securing the ends of wire ropes to prevent fraying. The common and useful type of end fitting for a wire rope is to turn the end back to form a loop. The loose end is then fixed back on the wire rope. Termination ef
