Basic Wire Rope Components
Wire rope consists of three basic components:
- the wires that form the strand
- the strands that lay around the core
- the core which the foundation of any wire rope.
These basic wire rope components vary both in complexity and configuration to produce a wide range of wire ropes for specific purposes and applications.
Wires can be made from a variety of materials, the most common being high-carbon steel. This is available in a variety of grades which are pre-determined in the manufacture of the rope based on the intended use and application of the wire rope.
Strands are made up of two or more wires, laid in any one of the many specific geometric arrangements, or in a combination of steel wires with some other materials such as natural or synthetic fibres.
The Core is the foundation of a wire rope; it is made of materials that will provide proper support for the strands under normal bending and loading conditions. Core materials include fibres (hard vegetable or synthetic) or steel. A steel core consists either of a strand or an independent wire rope.
The three most commonly used core designations are: fibre core (FC), independent wire rope core (IWRC), and wire strand core (WSC).
Conventional wire ropes are used in a wide range of applications: lifting, hoisting, lashing, towing, mooring, hauling, logging, drilling, etc. A wide range of sizes and constructions are available for various usages. Different constructions have different characteristics suitable for different uses depending on the design’s requirement of the strength, fatigue resistance, wear resistance, flexibility and abrasion resistance.
How to Measure Wire Rope
Measure the circle just touching the extreme outer limits (crown) of the strands.
