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.

Wire Rope can be seen all around us, even if we may not always register it! It is most commonly used to lift or support objects but can sometimes just be used for aesthetic purposes and it can have many advantages.

Even aviation and marine industries along with water and sewage treatment facilities use it -though often the stainless-steel variety due to its high corrosion resistance.

Steel cable is also often used for architectural purposes as it is known for its strength, versatility and aesthetic properties. A common example is suspension bridges.

One of the reasons for the wide range of uses is the different end fittings that can be attached to the rope to enable them to fit to any anchor point and also to adjust to the required tension.

In our workshop we produce many different types of rope assemblies on a daily basis, some of the most common types we produce are trailer ropes, rigging rope, lifting slings, zip wires and many custom assemblies. We often supply many multiples of these to our regular customers; however we are happy to make individual ropes for special tasks.

Rope wire comes in many different constructions, for example, right or left hand lay; wire or fibre core, and the amount or fibres and wires included in the completed rope. It can easily become confusing especially if you add in the non-rotating rope option. Talk to the specialists about your needs to ensure you get the right one for your intended purpose. Using the wrong rope can be disastrous.

Stainless steel wire rope is used in different tasks and areas togalvanized rope, this is because of its differing properties. Due to the fact that stainless steel is aesthetically pleasing to the eye it is popular for home interior projects likebalustrade on stairs, hanging shelves or other decorative features. As stainless is very corrosion resistant its outdoor use is endless, perfect for highlighting garden areas or as decking balustrades.

Stainless steel is a steel alloy made from many elements. It is different from standard steel because of the chemical compounds it contains, specifically Chromium and Carbon. The Chromium mass must be a minimum of 10.5% and carbon no more than 1.2% to be stainless steel.

One of the main advantages is its corrosion resistance which increases as the chromium content is raised, or Molybdenum is added. This means it will not succumb to uniform corrosion and rust so can be used for applications where the rope may get wet, such as in marine environments. Indeed, our ropes are graded AISI 316 so they can be used in marine environments. They also comply with EN12385 and EN10264.

It also resists staining so the aesthetics of the wire rope will not change, making it an attractive choice for many interior design projects for things such as barriers and balustrades in public areas such as shopping malls and public attractions.

At Rope Services Direct, our range is second to none and we can supply you with stainless steel wire rope. If you would like to find out more, please don’t hesitate to contact us on 01384 78004.

We also supply to the water treatment industries where it is constantly utilised in wet conditions. The marine and aviation sectors also these ropes for many tasks. More commercially these ropes are used in architecture and as safety barriers in public areas.

There are many different diameters available. They are commonly found in diameters ranging from 3mm to 76mm. It’s important to choose the right diameter as a 50mm rope would be no use round a pulley with a groove of 10mm.

One of the most important considerations is how you will use it. This is especially true if it is being used in the lifting industry, where if the rope fails then serious injuries can occur. It is of the upmost important that you examine the rope for signs of wear and if in any doubt, do not use. It is also a good idea to have a regular inspection and testing schedule, carried out by a suitably qualified person so that you know the rope is fit for purpose and safe.

Whatever type of rope wire you choose, it is important to be aware of the properties and construction of it so that you are using the correct rope and also enhances your safety knowledge.

In manufacturing it, hundreds of tiny metal filaments are wrapped, twisted and braided together to make the inner wires. These will then turn into strands by twisting together the smaller inner wires / filaments. Twisting strands in various ways around a central core is what makes the wire rope. It is how they are twisted which gives them their differing properties e.g. non-rotating, low stretch, higher breaking strength. There are also different constructions depending on left and right hand lay.

Note: The numbers used when describing a rope denote the number of wires and strands within it. For example, a 6 x 36 wire rope has 6 strands made of 36 wires. Likewise, a 7 x 19 has 7 strands with 19 wires. Strength and/or flexibility is provided when the strands are twisted around an inner core which can be steel wire or fibre core.

Due to their construction, it’s important to identify any broken wires or strands which could have severe consequences if used without inspection and testing. However, if a few strands break during a specific lift, it is more likely the intact wires and strands will hold the load whilst it is safely lowered – then the rope can be destroyed. It is this property which makes them safer than chains because if a chain link breaks then the load will likely fall.

There are many factors which can affect them, including bad coiling using pulleys and sheaves etc., grooves that are too big or too small, excessive pulling angles or twisting the rope in the opposite way to its ‘lay construction’, dirt ingress and poor lubrication to name but a few.

Handling it can impart numerous hazards. From metal splinters when cutting the rope to acute bruising if the rope abruptly recoils so vital safety strategies must be adapted when handling the product.

Before unreeling – make sure the floor space is clear so that the rope can be pulled off the reel in a straight line safely. The rope must always be pulled from the top, not the bottom of the reel and it should be pulled in a straight line which should minimise the danger of bending or kinking the wires, which will permanently damage it and make it unusable.

If it"s in a coil rather than a reel, then the only safe way to remove the rope is to carefully roll the coil in a similar way to pushing a child’s loop, again ensuring the surrounding area is clear of debris.

Equally, it can be damaged when it is being reeled back up again after use. You need to keep it wound tightly and wind it the same way the wire has been wound out which will avoid reverse bending of the rope. You should also ensure the wire is wound over the top of the reel to ensure it’s even and to avoid the bottom layers crushing.

Storage should be ideally on a rack, stand or pallet and not on the ground. It is also important to store the rope in a clean, cool and dry environment as moisture or condensation can develop amid the wires and begin the decay process rendering the rope unusable – waterproof containers and breathable tarpaulin like bags should ideally be used if the rope is stored outside.

Wire ropes are lubricated during manufacture but further lubrication at frequent intervals should be done, especially if it’s being stored for long periods of time. This will help to shield it from moisture ingress.

You should try to keep the rope elevated, off the floor to allow good air circulation. Reduce the risk of the rope becoming contaminated with dirt, dust and other particles that may affect it.

Storing rope should be done in such a way that it will not be at risk from any accidental damage. Either whilst in storage or whilst removing the rope from the storage area.

Overall, always remember manufacturers guidelines and instructions should be followed at all times to keep safe and prolong the life of the rope. If you are unsure if a rope is fit for purpose, always get it inspected and load tested which ought to be done regularly anyway.

The use of wire rope, sometimes called steel cable, steel sling rope, or steel rigging wire, is extremely popular in the material handling industry. Wire ropes come in a huge variety of designs and constructions, all suited for different lifting applications. Each type of wire rope has benefits and drawbacks. What all wire ropes have in common however, is that they are made up of steel wires which form individual stands. These strands are laid in a helical pattern around a fiber or steel core to form the rope. Different wire configurations and strand structures offer specific benefits to fit virtually any rigging application. These benefits include:

Selecting the correct wire rope for your rigging application often requires the rigger to make a compromise between different steel cable properties. For example, a wire rope with a small number of large outer wires will be more resistant to crushing, but less resistant to bending fatigue. Conversely, a wire rope with a larger number of small outer wires will be more bending fatigue resistant but less crushing resistant. These differences not only change the way the wire rope is used but they also change the way the wire rope is to be properly cared for.

Here at Tri-State Rigging Equipment we pride ourselves on providing our customers with only the highest quality steel wire ropes, from only the most reputable manufacturers. We can provide you with any rigging product on the market so if you cannot find what you are looking for, or if you don’t know exactly what you need, call or email our sales team to speak with a rigging product specialist.

The wires of a cable rope are the smallest component and are twisted together to form individual strands. Wires can be constructed in a variety of materials and grades, all affecting the properties offered by the cable rope. These materials include:

These different materials and grades affect the cable rope’s strength, bending fatigue resistance, corrosion resistance, wear resistance, and curve of the wire rope.

The strands of the steel cable consist of two or more wires and are laid in a helical pattern around the core. The way strands of steel cable are laid affect the properties offered by the steel cable.

The job of the core inside a steel cable rope is to support the strands and keep them in place relative to each other when bending and when under load. Wire rope cores can be made of a variety of materials including natural fiber, synthetic fiber and steel.

The lubrication of a steel cable rope is extremely important and often overlooked. Wire rope lubricant is added during the manufacturing process and penetrates the wire rope throughout, core included. The purpose of wire rope lubrication is twofold. First, it reduces friction between wires and strands. Second, it provides corrosion resistance to wires, strands and the core. A lack of proper lubrication is very serious and is cause to remove any and all affected wire rope from service.

In a preformed steel wire rope, the wires and strands are manufactured into the helical shape they will take when the wire rope is constructed. Preformed wire rope offers more flexibility and fatigue resistance than non-preformed wire rope. This allows the rigging wire to be uniformly spooled on a drum.

When riggers talk about the lay of a rope, they are talking about two things. One, the way the wires are laid to form a strand (right or left), and two, the way the strands are laid around the wire rope core (regular, lang, or alternate).

Regular Lay: The wires are parallel with the core of the rope. The direction of the wires is opposite to the direction of the strands. Compared to lang laid wire rope, regular lay offers more crushing and rotation resistance, allowing it to spool better on a drum.

Lang Lay: The wires are laid at an angle to the wire rope core. The direction of the wires is the same as the direction of the strands. Compared to other wire rope lays, lang lay offers more bending fatigue and abrasion resistance.

Wire ropes can be constructed using one of the five main strand patterns or a combination of two or more of the basic strand patterns. The wire rope strand pattern refers to the number of wires per layer, the number of layers, and the size of the wires. The strand pattern of a wire rope is a very important determining factor when it comes to choosing the correct wire rope for your specific rigging application. The five basic strand patterns are:

Filler Wire: This strand pattern is constructed by laying two layers of same sized wires around a center. The outer layer will have 2x the amount of wires than the inner layer. In the valleys of the inner wires are small filler wires to fill in the gaps between the inner and outer layers.

Seale: A layer of same sized wires smaller than the center wire is laid around the center. The outer layer consists of the same amount of wires as the inner layer but bigger in size. The outer wires lay in the valleys of the inner wires.

Warrington: This strand pattern consists of two wire layers. A layer of wires is laid around a same sized center wire to form the inner layer. The outer layer is formed by laying wires of alternating sizes, big and small, around the inner layer. The larger outer wires lay in the valleys of the inner wires and the smaller outer wires lay on the crowns of the inner wires.

Combination: A combination wire rope strand pattern is constructed by combining two or more of the strand patterns above to form a single unique strand pattern.

Fiber cores offer riggers more flexibility due to their natural or synthetic polypropylene fibers. This also means, however, that fiber core wire ropes are more susceptible to crushing and are not suitable for high heat environments.

In environments that exceed 180° F, a steel wire rope core should be used. Steel wire rope cores can be either an independent wire rope or an individual wire rope strand. Steel wire rope cores offer greater support for the strands and wires of the steel cable when compared to fiber cores.

The classification of a wire rope is based on the number of strands, as well as the number of wires in each strand. Below is a table of the most common wire rope configurations arranged in specific classifications.

In addition to the general classifications of steel wire rope, here at Tri-State Rigging Equipment, we also offer a wide range of specialty wire rope constructions. These include:

Rotation Resistant Wire Rope: This special construction of steel cable rope is designed to resist twisting and turning while under load. Rotation resistant wire rope must be specially cared for to prevent introducing twist into the rope.

Compacted Strand Wire Rope: This special type of wire rope is constructed using compacted outer strands. The outer strands are run through rollers or a die before the rope is closed. This increases the density of the outer stands and gives the steel cable rope a smoother outer surface. Compacted strand wire ropes offer greater strength and durability than standard round wire rope.

Swaged Wire Rope: Unlike a compacted wire rope, a swaged wire rope is compacted using a swaging machine after the wire rope had been closed. The outer wires of a swaged wire rope can be either compacted or round. Like compacted strand wire rope, swaged wire rope offers more strength and durability when compared to similar sized round wire ropes, however, it offers less bending fatigue resistance.

Plastic Coated Wire Rope: This type of wire rope is coated in a layer of plastic to protect the rope from abrasion, wear, and environmental factors. A drawback to plastic coated wire rope is that the plastic coating covers the strands and wires making it harder to inspect the wire rope.

Plastic Impregnated (PI) Wire Rope: A plastic impregnated wire rope is filled internally with a matrix of plastic that fills the gaps between wires and strands. This plastic filling reduces internal friction and improves bending fatigue resistance.

Plastic Coated or Plastic Filled IWRC Wire Rope: This type of wire rope features an independent wire rope core that is either filled or coated in plastic. This reduces internal friction in the wire rope and gives the wire rope greater bending fatigue resistance.

Tri-State Rigging Equipment is a service provider and distributor for all steel wire rope and steel cable for rigging and lifting, serving clients from coast to coast, Canada, Mexico and especially focused in the states of Missouri, Illinois, Indiana, Iowa, Kansas, Nebraska, Arkansas, Mississippi, Tennessee, Kentucky, South Carolina, Florida, and Oklahoma.

Domestic wire rope is defined by the Committee of Domestic Steel Wire Rope and Specialty Cable as wire rope that is stranded and closed in the USA. It is key to note that the requirement allows for some of the materials making up the rope product to be imported from outside of the USA.

The Buy America Act requires 100% of a product to be manufactured in the USA, including the steel mill products. To fit Buy America requirements, the melting of the steel, the stranding, and the closing process must be performed within the USA.
