<\/figure>\n\n\n\nWire rope is a preferred lifting device for many reasons. Its unique design consists of multiple steel wires that form individual strands laid in a helical pattern around a core. This structure provides strength, flexibility, and the ability to handle bending stresses. Different configurations of the material, wire, and strand structure will provide different benefits for the specific lifting application, including:<\/p>\n\n\n\n
- \n
- Strength<\/li>\n\n\n\n
- Flexibility<\/li>\n\n\n\n
- Abrasion resistance<\/li>\n\n\n\n
- Fatigue resistance<\/li>\n\n\n\n
- Crushing resistance<\/li>\n\n\n\n
- Corrosion resistance<\/li>\n\n\n\n
- Rotation resistance<\/li>\n<\/ul>\n\n\n\n
However, selecting the proper wire rope for your lifting application requires some careful thought. Our goal is to help you understand the components of a wire rope, the construction of wire rope, and the different types of wire rope and what they might be used for. This will allow you to select the best performing and longest-lasting wire rope for the job at hand.<\/p>\n\n\n\n
A Wire Rope Is a Machine with Many Moving Parts<\/strong><\/h2>\n\n\n\n
From childhood, many of us have been conditioned to think of a machine as some device with gears, shafts, belts, cams, and assorted whirring parts. Yet, by the rules of physics, an ordinary pry bar is a simple machine, even though it has only one part.<\/p>\n\n\n\n
A wire rope is, in reality, a very complicated machine. A typical 6 x 25 rope has 150 wires in its outer strands, all of which move independently and together in a very complicated pattern around the core as the rope bends. Clearances between wires and strands are balanced when a rope is designed so that proper bearing clearances will exist to permit internal movement and adjustment of wires and strands when the rope has to bend. These clearances will vary as bending occurs, but are of the same range as the clearances found in automobile engine bearings.<\/p>\n\n\n\n
Understanding and accepting the \u201cmachine idea\u201d gives a rope user a greater respect for rope, and enables them to obtain better performance and longer useful life from rope applications. Anyone who uses a rope can use it more efficiently and effectively when they fully understand the machine concept.<\/p>\n\n\n\n

<\/figure>\n\n\n\nThere are four basic components that make up the design of a finished wire rope:<\/p>\n\n\n\n
- \n
- Wires made from metal that form a singular strand<\/li>\n\n\n\n
- Multi-wire strands laid around a core in a helical pattern<\/li>\n\n\n\n
- A fiber or steel core<\/li>\n\n\n\n
- Lubrication<\/li>\n<\/ol>\n\n\n\n
Wire<\/h3>\n\n\n\n
Wires are the smallest component of wire rope and they make up the individual strands in the rope. Wires can be made from a variety of metal materials including steel, iron, stainless steel, monel, and bronze. The wires can be manufactured in a variety of grades that relate to the strength, resistance to wear, fatigue resistance, corrosion resistance, and curve of the wire rope.<\/p>\n\n\n\n
The wires themselves can be coated but are most commonly available in a \u201cbright\u201d or uncoated finish.<\/p>\n\n\n\n
Strands<\/h3>\n\n\n\n
Strands of wire rope consist of two or more wires arranged and twisted in a specific arrangement. The individual strands are then laid in a helical pattern around the core of the rope.<\/p>\n\n\n\n
Strands made of larger diameter wires are more resistant to abrasion, while strands made of smaller diameter wires are more flexible.<\/p>\n\n\n\n
Core<\/h3>\n\n\n\n
The core of a wire rope runs through the center of the rope and supports the strands and helps to maintain their relative position under loading and bending stresses. Cores can be made from a number of different materials including natural or synthetic fibers and steel.<\/p>\n\n\n\n
Lubrication<\/h3>\n\n\n\n
Lubrication is applied during the manufacturing process and penetrates all the way to the core. Wire rope lubrication has two primary benefits:<\/p>\n\n\n\n
