Types of Wire Rope Products
There are a wide variety of products that are produced using wire rope. The demand for wire rope products is due to its strength, durability, and reliability. Since the basic purpose of wire rope is to lift and move heavy materials and items, the most common type of wire rope product is the wire rope sling.
Wire Rope Slings –
Though the construction of soft eye wire rope sling is very similar for all types, there are certain variations applied to slings to adjust them to fit different applications. Slings are configured in various ways to fit different types of loads. These changes are referred to as hitches.
Vertical Hitch: A vertical hitch is where one eye of the wire rope is attached to the hook and the other eye is attached to the load.
Thimble hand spliced wire rope sling: To add to the strength of wire rope slings and lessen the stress on a small area of the eye, a thimble, a U shaped piece into which the wire rope fits, is placed in the eye, which helps the sling to retain its natural shape. The thimble is positioned to prevent the hook or load from coming in contact with the wire rope.
Coiled Wire Rope –
Coiled wire rope is made from bundles of small metal wires that are twisted into a coil. It comes in many varieties and is easy to store since it does not require a spool. Coiled wire rope is produced in coils. When it is not in use, it springs back into a coil, which makes it easy to handle.
Cable Wire Rope –
Cable wire rope is 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.
Push Pull Wire Rope –
Push pull wire rope assemblies are used to send force and are used in the aircraft, exercise, medical, automotive, and office equipment industries. Unlike using a single heavy wire, push pull assemblies made with wire rope are stiffer and have a larger bend radii for smoother motion of the wire.
Wire rope lanyards are a standard wire rope product that have a multitude of uses. They are produced using the same process that is used to produce wire rope with the same numbering categorizing system. Lanyards are used to hold fasteners, hardware, or components to prevent loss of an item or prevent injury.
As can be seen in the image below, lanyards come with a variety of connectors to specifically fit an application. Custom designed lanyards are designed for unusual and unique functions where a standard lanyard will not fit. The variety of connectors allows the lanyard to be easily connected.
Chapter Four – How Wire Rope Products are Made
In many ways, wire rope is a form of machine with multiple moving parts. Normally, when we think of a machine, we imagine a device with a motor, drives, and gears. Wire rope does not have any of those components but does fit the definition of being a complex mechanism. It has moving parts that work together to move heavy materials and loads.
The main function of wire rope is to do heavy lifting, which is very dependent on endless wire rope sling. The type of sling is determined by the quality of the wire rope used to form them and whether several ropes have been braided or wound together.
The Parts of Wire Rope
The parts of wire rope are wire, a core, strands, and lubricant.
Wire is the smallest part of wire rope but makes up the various strands. The composition of the wire can be steel, iron, stainless steel, copper, or other types of metal wires and are produced in different grades. The individual wires can be coated or bright, meaning uncoated.
Strands are sets of wires that are twisted together and are placed in a helical pattern around the core. The size of the wire determines its abrasive qualities with larger wires being more abrasive and less flexible than smaller ones.
The core is the center of the wire rope and serves as a support for the strands and helps the wire rope keep its position when it is under stress or bearing a load.
Lubrication is applied during the manufacturing process to reduce friction between the wires and strands as well as protection from corrosion and rust. The tight winding of the wires enhances the ability of the wire rope to retain the lubrication which is essential to its longevity.
Manufacture of Wire Rope Slings
Of all of the products that are made from wire rope, slings are the most common and widely used. These looped wire ropes come in different varieties and grades depending on the type of wire used. Also, to enhance wire sling performance, several wire ropes may be wound together to form a sturdier and more reliable sling.
For delivery for processing, wire rope is spooled. The production of grommet wire rope sling begins with unspooling the wire rope.
