single layer wire rope for sale

While some use these two terms interchangeably, technically wire rope refers to a diameter greater than 3/8”. Cable rope - also called aircraft cable - applies to all smaller variations.

Consequently, aircraft cable is only used for lighter-duty purposes, such as winch lines, fences, and railings, while wire rope can be using for lifting, towing, hoisting, etc. Both are ideal for outdoor environments because the strength and length remain constant regardless of whether they are wet or dry.

Generally composed of wires, strands, and a core shaped in a spiral pattern, wire rope is incredibly durable. Steel wires are aligned in a precise helix geometric pattern to form a strand in a process known as "stranding." A "closing" comes next, where the strands are laid around the core to form a wire rope.

The greater the diameter, the greater the break strength. Our selection of 1/8" stainless steel cable has a break strength of less than 2,000 lbs., while our 2-1/2" wire rope has a break strength of more than 600,000 lbs.!

Right hand and left hand designations indicate which way the strands wrap around the core of the steel rope, while regular lay and Lang lay designations specify which way the wires that make up the strand are formed in the helix pattern.

Regular lay means the wires are rotated opposite the direction of the strands around the core. Lang lay means the wires are twisted in the same direction as the strands wrapped around the wire rope core.

Our wire rope lay is right hand regular lay, with strands wrapped around the core to the right, and the wires making up the strand turned and rotated to the left.

Independent wire rope cores (IWRC) are made from steel, offer more support to the outer strands, and have a higher resistance to crushing. IWRC also offer more resistance to heat and increase the strength of the rope.

This refers to how many strands make up the rope and how many wires make up one strand. For instance, a 6x26 wire rope has 6 strands around a core with 26 wires making up each strand.

All wires consist of layer(s) arranged in a specific pattern around a center. Pattern designation is affected by the size of the wires, the number of layers, and the wires per layer. Wires can utilize either a single pattern style or a combination of them, known as a combined pattern:

Warrington - Two layers of wires. The outer layer has two diameters of wire (alternating between large and small), while the inner layer has one diameter.

Although wire rope is extremely strong, it can become damaged with improper use, making it unsafe to use. It"s important to have regular inspections for breaks, corrosion, overuse wear, and kinks.

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.

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.

Our company can supply bright wire rope, galvanized wire rope, stainless steel wire rope, compacted wire rope, rotation resistant wire ropes, mining wire rope, elevator wire rope, crane wire rope and gas & oilfield wire ropes. Here are some details to solve the problem that may puzzle you whether you are browsing the web or picking up steel wire ropes.

Bright steel wire ropes mean no surface treatment is applied to the rope. Therefore, they have the lower price among these three wire ropes. Generally, they are fully lubricated to protect the rope from rust and corrosion.

Galvanized steel wire ropes feature compressed zinc coating for providing excellent corrosion resistance. With higher break strength yet lower price than stainless steel, galvanized steel wire ropes are widely used in general engineering applications such as winches and security ropes.

Stainless steel wire ropes, made of quality 304, 305, 316 steels, are the most corrosive type for marine environments and other places subjected to salt water spray. Meanwhile, bright and shiny appearance can be maintained for years rather than dull as galvanized steel wire ropes.

Steel wire ropes are composed of multiple strands of individual wires that surrounding a wire or fiber center to form a combination with excellent fatigue and abrasion resistance. These wires and strands are wound in different directions to from different lay types as follows:

Beside above lay types, alternative lay ropes which combine regular lay and lang lay together and ideal for boom hoist and winch lines, can also be supplied as your request.

Two main methods about seizing steel wire ropes in conjunction with soft or annealing wire or strands to protect cut ends of the ropes form loosening.

Wire rope is technically defined as multi-wire strands laid geometrically around a core while also used more generally as a term to classify multiple product families including aircraft cable, coated aircraft cable, general purpose wire rope, strand, rotation resistant wire rope, compacted/swaged wire rope, and cable laid wire rope.

Aircraft cable does not fit the definition of wire rope in the strictest sense as it does not have an independent core, but rather a strand core, in which the center is one of the strands that is laid with the outside strand layers. Aircraft cable is available in diameters 3/8" or less with breaking strengths similar to that of equal diameter independent wire rope core (IWRC) and is available in stainless steel and galvanized steel.

Wire rope can be galvanized via three processes. Listed from least corrosion-resistant to the most corrosion-resistant, they are electro-galvanizing, hot-dip galvanizing, and drawn-galvanizing. In addition to being the most corrosion-resistant types of galvanized wire rope, drawn-galvanized has another added benefit which is a breaking strength that is the same as bright wire rope does. Electro-galvanized and hot-dip galvanized wire rope have breaking strengths that are approximately 10% lower.

Wire rope is specified by the number of strands in the rope, the number of wires in each strand, and a description of the core’s material of construction. For example, the notation “6x7 FC” means that the rope has six strands with seven wires in each strand and a fiber core. Commonly used core designations include FC (fiber core), independent wire rope core (IWRC), wire strand core (WSC), and poly core (PC).

There are two elements to wire rope lubrication, the core, and outer strands. IWRC wire rope always has a lubricated core (unless specially ordered as otherwise). Bright wire rope always has lubricated outer strands.  Galvanized wire rope can be manufactured in either dry finish or lubricated with respect to the outer strands.  Typically stainless steel wire rope is manufactured with a lubricated IWRC and dry finish outer strands.

19x7 wire rope is recommended for hoisting unguided loads with a single-part line. The rotation-resistant properties of this rope are superior to those of the 8x19 class wire ropes, and are secured by two layers of strands. The inner strands are left lay, while the 12 outer strands are right lay, which enables one layer to counteract the other layer’s rotation.

Galvanized wire rope (steel) features a compressed zinc coating for providing excellent corrosion resistance. With a higher break strength, yet lower price than stainless steel wire rope, galvanized steel wire rope is widely used in general engineering applications such as winches and security ropes.

The bright class of industrial wire rope is produced without a surface treatment—making the rope less likely to untwist or kink while giving it a stronger crush resistance than lay ropes. Generally, they are fully lubricated to protect the rope from rust and corrosion. Also available in USA-made.

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. Most types of stranded ropes only have one strand layer over the core (fibre core or steel core). The lay direction of the strands in the rope can be right (symbol Z) or left (symbol S) and the lay direction of the wires can be right (symbol z) or left (symbol s). This kind of rope is called 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,formerly Albert’s lay or langs lay). 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.

Industrial wire ropeis used for a multitude of applications. Smaller wire ropes are found on exercise equipment and wire fencing, while ticker rope styles are used for aerospace and aircraft construction and suspension bridge reinforcement. Further, wire ropes are utilized by countless industries, including the military, construction, warehousing, automotive, and engineering.

Singe the application and requirements for wire rope is so varied,industrial wire rope suppliersoffer numerous specifications. Narrowing down through these options can be tricky if you are unsure of the exact requirements your application needs.can impact the use, durability, and strength of the wire ropes, and some types are specifically designed for unique functions.

One of the firstwire rope specificationsto narrow down is the material of the rope itself. While wire rope is generally made from steel, but it may also be made from iron, bronze, copper, and even titanium. Further, there are different types of steel grades and finishes available.

Most steel wire ropes are made from plow steel, which contains .5 to .95 percent carbon. Most wire ropes are available as either IPS (improved plow steel) or EIPS (extra improved plow steel). These improvements are based on the amount of carbon added in. So IPS are10% strongerthan traditional plow steel and EIPS is 10% stronger than IPS.

A steel grade measures the material’s strength and pliability. The higher the grade, the most weight the wire rope can sustain. Each level of grade is about 10% stronger than the next.

The lowest grades for wire rope are mold plow and plow steel. These are often used for hauling and logging, but are not approved for overhead lifting applications.Industrial wire ropesarefrom improved plow steel (IPS) or extra improved plow steel (EIPS).

Stainless steel wire ropes have an additional grading system that uses numbers to measure the amount of chromium added. 302-grade is an extremely tough type of stainless steel that is highly heat-resistant due to its high carbon content. 304 is highly versatile and corrosion resistant as it has chromium and nickel added. Grade 316 is considered theforwire ropesas it has a bit more flexibility with lower carbon content.

The nextwire rope specificationis the construction of the rope, meaning the number of strands woven together to form the rope. The general rule of thumb here is that the fewer strands in a rope, the stiffer it will be. So, when flexibility is necessary, you should opt for a wire rope with a higher strand count.

The number of strands and wires are written out as strand X wire count. A strand is made up of individual wires wrapped together, then each of the strands is woven together to form the rope. So, a 6 X 19 wire rope is made of 6 strands of 19 wires each.

Industrial wire ropes can be made of different patterns and arrangements. This impacts the wire rope’s performance and flexibility, so different patterns may be better suited for certain applications.

Filler Wire – The interior layer is made of uniform strands, then half the number of strands are added in a smaller diameter. The outer layer contains the same amount and size of strands as the inner layer.

Seale – A larger internal code strand is surrounded by two layers of an equal number of strands. One is a smaller diameter while the outermost layer is the same size as the inner core.

Warrington – This rope is made from two alternating diameters which are woven together so the smaller strands fill in the “valleys” between the larger strands.

The performance of a wire rope is the description of the lay or the direction the strands are wrapped in. This subtle difference can actually influence many factors, like the rope’s flexibility and fatigue resistance.

Regular Lay – The wires of the rope align with the axis, so the direction of the strands is opposite to the strand lay. This reinforces the wire rope to protect it from crushing and makes it more resistant to rotation.

Lang Lay – This is the opposite of the Regular Lay, so the wires and strands are going the same direction as the core. This increases the fatigue resistance of the rope and is best for abrasive applications.

Next, you will need to narrow down the finishes for thewire ropes. A bright wire rope has no coating, so the steel is completely exposed. This is only recommended for applications where the rope will not be exposed to moisture or water, as the steel is not rust-proof.

Galvanized steel is coated in a thin layer of molten zinc. This provides a protective barrier for added durability and corrosion resistance. The zinc coating gives the rope a more matte appearance.

Although wire ropes are incredibly durable, the steel will wear out faster if it is exposed to harsh elements. Constant friction and changing temperatures and humidity in the air can weaken the metal and lead to wires breaking or corroding.

Wire ropes may be lubricated to reduce friction and protect the rope from corrosion. This is optional, but it can be beneficial for certain uses. Wire rope lubricants can be made from minerals or oils and may be either thin and runny or thick and tacky.

Wire rope is a collection of metal strands that have been twisted and wound to form the shape of a helix with the purpose of supporting and lifting heavy loads and performing tasks that are too rigorous for standard wire. On shipping docks, rigging, and load bearing equipment, wire rope is attached to swivels, shackles, or hooks to lift a load in a controlled, even, and efficient manner.

The uses for wire rope include adding support to suspension bridges, lifting elevators, and serving as additional reinforcement for towers. The design of wire rope, with its multiple strands wrapped around a stable core, provides strength, flexibility, and ease of handling for applications that have bending stress.

Individual designs of wire rope involve different materials, wire, and strand configurations as a means for supporting and assisting in the completion of lifting or supportive applications.

The term wire rope encompasses a wide range of mechanical tools that are made to perform heavy and extreme lifting jobs. Wire rope is a complicated and complex tool with multiple moving parts capable of moving in unison. A 6 by 25 wire rope has 150 outer strands that move as one in an intricate pattern supported by a flexible core.

An essential part of the design of wire rope is the required clearance between the strands to give each stand the freedom to move and adjust when the rope bends. It is this unique feature that differentiates wire rope from solid wire and other forms of cable.

The basic element of wire rope is wire that is used to configure, shape, and form the rope. Typically, steel, stainless steel, and galvanized wires are the first choice with aluminum, nickel alloy, bronze, copper, and titanium being second possibilities. The choice of wire is dependent on the type of work the wire is going to be used to perform with strength, flexibility, and abrasion resistance being the major determining factors.

Stainless steel wire rope has all of the basic qualities of galvanized and general wire rope with the added benefits of corrosion and rust resistance; this makes it the ideal choice for harsh and stressful conditions.

Steel wire rope is classified as general purpose wire rope and comes in a wide variety of sizes, diameters, and strengths. It is the most common type of wire rope and is used for several industrial, manufacturing, and construction applications.

Before going further into the discussion of how wire rope is made, it is important to understand the numbers used to describe each type. All wire ropes have a core around which wires are wound. The various styles of cores vary according to the construction and design of the requirements of the wire rope that is being produced.

Wire rope is classified by the number of strands it has as well as the number of wires in each strand. The most common classification is a seven wire rope that has one strand in the center and six around its circumference. This type of wire rope is lightweight with a very simple construction. The majority of wire ropes are more complex and intricate with multiple intertwining strands and wires.

What must be understood about wire rope is that it has a complicated configuration. It is actually wires wrapped around wires to form bundles that are wrapped around other bundles. In the case of a seven wire wire rope, the core has bundles of wires wound around it; this can be seen in the image below.

The first step in wire rope creation is the production of wire strands where wires are wound around a single core wire. The number of wires included in the strand is dependent on the specified strength, flexibility, and size requirements of the rope. Once the strand is completed, it is straightened before being moved to wire rope construction.

Like wire ropes, strands have different patterns; patterns are the arrangements of the wires and their diameters. Though most strands have a core, there are strand patterns that have three or four wires without a core that are referred to as centerless strands. The design of each strand pattern is meant to enhance the strength of the wire rope and improve its performance.

For a multiple layer strand, the layers of wire are placed over one another in successive order. The placement of the wires on top of each other must be such that they fit smoothly and evenly.

The Warrington pattern is like the multiple layer pattern with one variation. Like the multiple layer pattern, the inner wires and the core are the same and have the same diameter. The difference is in the outer layer, which has wires of alternating sizes of large and small with larger diameter wires laying in the valleys of the inner wires.

All of the wires of a filler pattern are the same size. What makes this pattern unique is the insertion of small wires in the valleys of the inner wires to fill the gap between the inner and outer layer.

The flattened strand pattern is also known as the triangular strand, which can be triangular or oval. Three round wires form the core. The outer flattened surface has a greater sectional metallic area; this makes this pattern stronger and longer lasting.

The core of a wire rope runs through the center of the rope and can be composed of a variety of materials, which include synthetic fibers, natural fibers, a single strand, or another wire rope. The core supports the wound strands, helps maintain their position, is an effective lubricant carrier, and provides support.

Wire ropes with fiber cores are restricted to light loads and are not used in severe, harsh, or stressful conditions. Polypropylene and nylon are types of synthetic fiber cores and can be used in conditions where there is exposure to chemicals.

Cores made of wire are classified as independent wire cores. The core of a wire rope with a wire core is actually a wire rope with another wire rope serving as the core, as can be seen in the diagram below. These types of wire ropes are used where the rope will be exposed to exceptional resistance and crushing.

A strand, or wire strand core, is exactly like the rest of the strands of the wire rope with wires of the same diameter and size as the other strands.

The choice of core and creation of the strands are the simplest yet most essential parts of wire rope construction. Wire rope lays, the method used to wind the strands, is more complex and involves several choices.

Lay is a term used to describe three of the main characteristics of wire rope: direction, relationship, and linear distance. The strands can be wrapped around the core going right or left. Right or left refers to the direction of the strands wrapped around the core and the wires within the strands. The linear distance is how far a strand moves when it is making a revolution around the core.

In a regular lay, the wires and strands spiral in opposite directions. With a right hand regular lay, the wires spiral to the left and the strands to the right. In the left hand regular lay, the wires spiral to the right and the strands to the left. This type of lay is easy to handle but wears out quickly because the crown wires are in contact with the bearing surface.

In the Lang, or Albert, lay, the wires and strands spiral in the same direction with right hand lay being the most common. The wires in a Lang lay appear to run parallel to the center line of the rope. The difficulty with Lang lay wire ropes is handling since they tend to kink, twist, and crush.

Wire rope is an exceptionally strong tool that has been configured and designed to withstand the stress placed upon it through rigorous and continual use. In most applications, wire rope has to endure extreme stress and strain. It is for these reasons that coatings have been developed to protect wire rope from abrasions, corrosion, UV rays, and harmful and damaging chemicals.

Three main types of coatings are used to protect wire rope: polyvinyl chloride (PVC), polypropylene, and nylon. Of the three types, PVC is the most popular.

In cases where there are severe and hazardous working conditions, polypropylene is the recommended choice since it is capable of protecting wire rope against corrosion and chemical leaching. Additionally, it is resistant to impact damage and abrasion. Polypropylene is a tough, rigid, and crystalline thermoplastic that is made from a propene monomer and is resilient as well as inexpensive.

Braided wires are electrical conductors made up of small wires that are braided together to form a round tubular braid. The braiding and configuration of braided wire makes them very sturdy such that they do not break when flexed or bent. Braided wires are widely used as conductors, are commonly made from copper due to copper"s exceptional conductivity, and can be bare or coated depending on the application.

Braided wire can be round and tubular or flat. Round tubular braids fit in most spaces where flat braided wire will not. Flat braided wire begins as round braided wire which is flattened on a capstan. They are exceptionally strong and designed for medical and aircraft applications.

Metals used to make wire rope are various grades of stainless steel, bright steel, and galvanized steel. Though the majority of wire rope manufacturers use these three metals, other metals such as copper, aluminum, bronze, and monel are also used on a limited basis.

The most important aspect of wire rope is the wire and the metal from which it is made. The strength and resilience of wire rope is highly dependent on the quality of metal used to make it, and these are essential factors to be considered when purchasing it.

Bright steel wire does not have a coating and is rotation resistant, (designed to not rotate when lifting a load). It is drawn from hot rolled rods that are put through a die to match its specific dimensional tolerances, mechanical properties, and finish. Bright wire is used as a single line in conditions that require a rope that will resist cabling.

Galvanized steel has a zinc coating for corrosion resistance and has the same strength and durability as bright steel. Environmental conditions determine the use of galvanized steel. In mildly severe and slightly harsh conditions, galvanized steel wire is an economical replacement for stainless steel.

In the manufacturing process, galvanized wire goes through the process of galvanization, a method of coating steel wire with a protective and rust resistant metal. Galvanized wire is exceptionally strong, rust resistant, and flexible enough to meet the needs of a variety of applications.

Wire rope made from copper is mostly used for electrical applications due to its exceptional electrical characteristics. The benefits of copper wire rope are its durability, flexibility, and resilience compared to standard copper wire. The strength of copper wire rope is seen in its use in applications where there are vibrations and shaking.

The wire rope lubrication process begins during its fabrication and continues during its use. Lubrication of wire rope is designed to lower the amount of friction it endures and provide corrosion protection. Continued lubrication increases the lifespan of wire rope by preventing it from drying up, rusting, and breaking.

The types of lubricants for wire rope are penetrating or coating with coatings covering and sealing the outside of the rope. Penetrating lubricants go deep into the rope and seep into the core where they evaporate to form a thick coating or film.

The application of the lubricant is dependent on the type of core. Fiber cores absorb the lubricant and serve as a reservoir that retains the lubricant for an extended period of time. With metal cores, the lubricant is applied as the wire is twisted into strands to give complete saturation and coverage of the wires.

There are several types of greases that are used as wire rope lubricating agents and are made up of oil, a thickener, and additives. The essential components are the base oil and additives, which influence the behavior of the grease. The thickener holds the base oil and additives together. The amount of base oil in a grease is between 70% and 95% with an additive of 10%.

The additive in grease enhances the positive properties of the oil and suppresses the negative properties. Common additives are oxidation and rust inhibitors as well as pressure, wear, and friction reducing agents.

Of the many choices for lubricants, vegetable oil is the easiest to use and penetrates the deepest. The design of the additives for vegetable oils gives them the necessary qualities required to penetrate deep into a wire rope. The exceptional penetration provides protection against wear and corrosion. Since vegetable oil is a fluid, it helps in washing the wire rope to remove external abrasive contaminants.

Wire rope is widely used in machines, structures, and varied lifting applications. Its type, size, and requirements are determined by how it will be used. Regardless of its use, wire rope guarantees exceptional strength and provides high quality and excellent performance.

The lifting of heavy loads for centuries involved the use of hemp rope or chains, neither of which was a guaranteed or substantial method. Early in the 18th Century, between 1824 and 1838, Wilhelm Albert, a German mining engineer, combined the twisting of hemp and strength of chains to create today‘s wire rope.

The most common use of wire rope is as a part of a crane hoist wherein it is attached to the hook of the hoist and wrapped around a grooved drum. The tensile strength and durability of wire rope makes an ideal tool for lifting and keeping loads secure. Though it is used in several industries, it is very popular for production environments wherein materials need to be lifted quickly and efficiently.

In addition to its many lifting applications, the strength and stability of wire rope is useful in other applications, especially in the aerospace industry. Pedals, levers, and connectors in the cockpit of an aircraft are connected with wire rope. The wires provide for the passage of power between systems and mechanisms; this allows control of the aircraft. Wire rope is used to control propeller pitch, cowl flaps, and the throttle. It also assists in lowering and minimizing vibrations.

Tires are reinforced with wire rope to increase their durability and strength. All automotive production environments make use of wire ropes for supplying materials, moving heaving loads, and positioning equipment. Wire rope can be found in the production of steering wheels, cables, exhausts, springs, sunroofs, doors, and seating components.

As surprising as it may seem, the place that wire rope has the greatest use is in the home, where its strength, long life, endurance, and resilience provide guaranteed protection and performance. The main reason wire ropes are so popular for home use is cost.

Inexpensive, easy to obtain, easy to install, and easy to maintain, wire ropes provide an additional method for performing home repairs and structural support. Their excellent flexibility and sturdiness combined with their invisibility has made wire rope an ideal solution to several home maintenance issues. It is used to support staircases, fences, decks, and hang plants.

The search and production of crude oil has relied on wire ropes for centuries to lift drill bits, insert shafts, and support oil rigs on land and the water. When equipment, machinery, and tools have to be lowered into the depths of the earth and sea, wire ropes are the tool that the oil industry relies on to do the job.

Many of the tasks of oil production require tools that are capable of enduring severe and harsh conditions. Wire ropes have to withstand enormous pressure, extraordinary stress, and a wide range of temperatures. The use of wire rope includes maintaining oil rig stability and moorings for offshore rigs.

Wire rope has long been a standard component for the transportation industry, from the cable cars of San Francisco to the lift chairs for ski resorts. For many years, cable cars have relied on heavy duty cables (wire ropes) to be pulled by a central motor from multiple locations. It is a method of transportation that has existed for centuries.

In Europe, funiculars use cables that hang from a support to move cars up and down a mountain with cables moving in opposite directions. The word funicular is from the French word funiculaire, meaning railway by cable. The terms wire rope and cable are used interchangeably when discussed by professionals. The first part of funicular, or funiculaire, is from the Latin word "funis," meaning rope.

The major use for wire ropes in the food and beverage industries is as a means for lifting and moving heavy loads. Wine barrels and containers full of ingredients are lifted and placed through use of cranes and wire ropes. They are also part of conveyor systems that move products from one station to another.

From the beginnings of amusement rides up to the present, wire ropes have been an essential part of attraction construction and safety. They pull cars on roller coasters, hold cabins that swing, and move carriages through haunted houses. The main concern of amusement parks is safety. The strength, stability, and guaranteed performance of wire ropes ensures that people who attend amusement parks will have a good time and stay safe.

The rigging used to complete the stunts in modern movies depends on wire rope for safety. Much like in amusement rides, wire ropes protect performers from injury and harm as they hang above a scene or carry out an impossible move.

The live theater industry uses wire ropes to raise and lower curtains, support overhead rigging, and hold backdrops and scenery pieces. During a production, rapid and efficient movement is a necessity that is facilitated by the use of wire ropes.

Wire rope is a tool that we tend to envision as indestructible, unable to succumb to any form of damage. Though it is exceptionally sturdy and strong as well as capable of enduring constant use, it is just as susceptible to breakdown as any other tool.

To avoid serious harm and damage, wire ropes should be scheduled for regular inspections. There are situations that can damage or break a wire rope; these should be understood prior to the problem arising.

Guide rollers have the potential to damage and cause abrasions on wire rope if they become rough and uneven. Of the various elements of a crane and lift, guide rollers have the greatest contact with the mechanism‘s wire rope. Regular inspection of guide rollers will ensure they are not damaging the rope or causing abrasions.

Bending is normally a regular part of wire rope usage; this occurs repetitively as the rope passes through a sheave. As a wire rope traverses the sheave, it is continually bent and develops cracks or breaks. The cracking and breaking are exacerbated by movement on and off the groove of the drum. Normally, the breakage happens on the surface and is visible. Once it appears, it accelerates to the core of the rope.

A bird cage is caused by a sudden release of tension and a rebound of the rope. This type of break requires that the rope be replaced since the place of the break will not return to its normal condition.

Wire ropes are multi-layered; this makes them flexible and torque balanced. The layering inside and outside creates flexibility and wear resistance. Relative motion between the wires causes wear over time, which leads to internal breakage. The detection of these breaks can be indicated by an electromagnetic inspection that calculates the diameter of the rope.

Kinked wire rope is caused by pulling a loop on a slack line during installation or operation; this causes a distortion in the strands and wires. This is a serious condition that necessitates rope replacement.

Corrosion damage is the most difficult cause of wire rope damage to identify, which makes it the most dangerous. The main reason for corrosion is poor lubrication that can be seen in the pitted surface of the rope.

The types of damage and problems listed here are only a small portion of the problems that can be caused if a wire rope is not regularly lubricated and inspected. Various regulatory agencies require that wire ropes be inspected weekly or monthly and provide a list of factors to examine.

As with any type of heavy duty equipment, wire rope is required to adhere to a set of regulations or standards that monitor and control its use for safety and quality reasons. The two organizations that provide guidelines for wire rope use are the American Society of Mechanical Engineers (ASME) and the Occupational Safety and Health Administration (OSHA).

All wire rope manufacturers and users closely follow the standards and guidelines established by OSHA and ASME. In the majority of cases, they will identify the specific standards they are following in regard to their products.

OSHA‘s regulations regarding wire rope fall under sections 1910, 1915, and 1926, with the majority of the stipulations listed in 1926 under material handling, storage, use, and disposal.

"Running rope in service shall be visually inspected daily, unless a qualified person determines it should be performed more frequently. The visual inspection shall consist of observation of all rope that can reasonably be expected to be in use during the day‘s operations. The inspector should focus on discovering gross damage that may be an immediate hazard."

"The inspection frequency shall be based on such factors as rope life on the particular installation or similar installations, severity of environment, percentage of capacity lifts, frequency rates of operation, and exposure to shock loads. Inspections need not be at equal calendar intervals and should be more frequent as the rope approaches the end of its useful life. Close visual inspection of the entire rope length shall be made to evaluate inspection and removal criteria."

ASTM A1023 covers the requirements for steel wire ropes with specifications for various grades and constructions from ¼ in. (6 mm) to 31/2 in. (89 mm) manufactured from uncoated or metallic coated wire. Included are cord products from 1/32 in. (0.8 mm) to 3/8 in. (10 mm) made from metallic coated wire.

United States Federal Spec RR W 410 covers wire ropes and wire seizing strands but does not include all types, classes, constructions, and sizes of wire rope and strands that are available. The purpose of Spec RR W 410 is to cover more common types, classes, constructions, and sizes suitable for federal government use.

Wire rope and wire seizing strand covered by United States Federal Spec RR W 410 are intended for use in general hauling, hoisting, lifting, transporting, well drilling, in passenger and freight elevators, and for marine mooring, towing, trawling, and similar work, none of which are for use with aircraft.

API 9A lists the minimum standards required for use of wire rope for the petroleum and natural gas industries. The types of applications include tubing lines, rod hanger lines, sand lines, cable-tool drilling and clean out lines, cable tool casing lines, rotary drilling lines, winch lines, horse head pumping unit lines, torpedo lines, mast-raising lines, guideline tensioner lines, riser tensioner lines, and mooring and anchor lines. Well serving wire ropes such as lifting slings and well measuring are also included in API 9A.

Wire rope is a collection of metal strands that have been twisted and wound to form the shape of a helix with the purpose of supporting and lifting heavy loads and performing tasks that are too rigorous for standard wire.

Individual designs of wire rope involve different materials, wire, and strand configurations as a means for supporting and assisting in the completion of a lifting or supportive task.

Steel Wire rope is a very complex machinery element which primary function is the transmission of tensile forces. Its basic constructional design allows repeated changes in the direction of pull through reeving systems incorporating drums and sheaves. General purpose wire ropeshave been developed and standardized in national and international standards . However the increasing demand for higher breaking strength, greater flexibility, better rotation resistance , and extended rope life cannot be met by such general purpose steel wire ropeconstructions. Horizon Cable is a stocking distributor for Python Wire Rope, which through research, development and engineering over many years has developed rope constructions that have significantly improved operating life. There are vast array of applications that Python Wire Rope can be installed by Horizon Cable Service in Oklahoma, Texas, Wyoming, Kansas, North Dakota and New Mexico to improve service life. Below are a few of the proven applications for our high performance wire ropes:

One benefit to High Performance Wire Rope is the increased breaking strength over standard wire ropes. This is achieved in the manufacturing process by compaction processes. Standard ropes are drawn which create a round outer circumference, but compacted ropes have flat outer service. The two types of compaction are STRAND COMPACTION and SWAGE COMPACTION. Strand compaction is the most popular, in this process the compaction is applied to the individual wires, where the swage compaction is applied to the entire wire rope itself. Both have their advantages for particular applications.

Rotation resistant ropes can fall under three different classes Spin Resistant, Rotation Resistant, and Non Rotating. In all of these types of wire ropes the outer layer is twisted opposite for the inner layers. Rotation resistant and spin resistant ropes will have one inner layer, while non-rotating lines will have multiple inner strands rotating a different direction from the outers.

6 strand high strength swage compacted rope that is perfect for applications that require a crush resistant rope to be used in multi-layer winding systems; e.g. boom hoist on lattice boom mobile and tower cranes

Python Compac 18 is recommended for bot multipart load and single part applications where medium rotational stability is needed. Use as main and auxiliary hoist line on Grove, link belt, Manitowoc, Terex and other us made mobile and truck cranes. Also used very successfully as a pulling rope on underground cable pulling winches.

Main and auxiliary hoist line for European type mobile and for all types of construction tower cranes which require a high strength rotation resistant rope construction. Excellent rotation resistant properties make this rope the preferred choice for all single and multiple line reeving systems.

Steel wire rope is a strong and durable rope used for fastening, securing, and positioning equipment because of its characteristics such as rigidity, toughness, and strength. Steel wire rope’s bending fatigue resistance is increased by adding a layer of plastic between outer strand, through an independent wire rope core (IWRC), and by increasing the area of contact between the sheave and steel wire rope.

Focus on bringing on new advancements and various other experimentation to South Africa by the key players is contributing to the growth of the South Africa steel wire rope market.

Increasing use of steel wire rope in mining, and oil and gas offshore transportation has largely contributed to the market growth. Ropes required at offshore need to be able to withstand extreme environmental conditions and which is why steel wire rope is used.

Corrosion resistance is one of the key trends that is increasing the demand for steel wire ropes. It increases the cost-effectiveness of the steel wire ropes as the non-corrosive nature keeps the wire intact, particularly in vital installations, and further enhances durability.

The report gives a detailed analysis of the following key players in the South Africa steel wire rope market, covering their competitive landscape and latest developments like mergers, acquisitions, investments, and expansion plans.

The strands in regular lay flows in the opposite direction due to which they have higher stability and greater resistance to crushing. These characteristics have resulted in regular lay type occupying a significant segment of the South Africa steel wire rope market.

The flow of the strands in lang lay are in same direction which makes pulling, lifting, pushing, and hoisting of objects easier. Lang lay steel wire ropes are also abrasion resistant and have superior tolerance to fatigue.

Alternate lay is a combination of lang lay and regular lay. It contains three strands of lang lay and other three of ordinary lay along, resulting in a combination of properties of both the lay types. Alternate lay steel wire ropes are typically used for special applications.

Different applications of steel wire ropes can benefit from different coating materials. Nylon is usually applied as a coating in order to prevent damage and corrosion of the steel wire rope. Meanwhile, vinyl and PVC are used as a coating for galvanised steel wire rope and stainless steel.

PVC is used for resistance from water and harsh weather conditions. PVC is widely adopted by individuals because it is cost-effective too. Nylon is tough when compared to other coatings which is why is used for various load running application. Nylon is considered for the largest market share holder in the South Africa steel wire rope market due to its toughness and damage protection capabilities.
