Wire ropes are used in many industrial applications, usually for lifting or pulling, but they can also be found in other uses. Wire ropes are made out of wire strands that are twisted together to make wire rope continuous lengths.
The wire is first wrapped around the base wire, creating wire strand bundles. These wire strand bundles are then tightly twisted together until a wire rope appears.
Different materials cover the wire rope to protect it from corrosion, heat, water, or other harsh environmental conditions. To protect the wire rope from outside elements, wire ropes are either coated with a layer of lubricant or have another layer wrapped around them before being used.
Some wire ropes are lubricated with wire rope lubricants to protect wire ropes before or during wire rope assembly.
There are wire rope lubricants for wire rope installation and wire outdoor rope uses. Wire rope lubricant is not the same as wire strand oil, applied on wire strands to keep them from rusting together.
Wire rope lubricant is applied on wire rope by wire rope manufacturers before the wire ropes are shipped to customers. Cradle, spooling, and other wire rope assembly operations should be done immediately after wire rope installation to prevent wire strand breakage. Wire ropes used for outdoor applications must first be treated with wire rope lubricant because wire ropes are susceptible to rust.
The wire rope lubricant should be applied evenly on wire ropes to prevent wire ropes from damaging each other.
The wire rope lubricant is applied to protect wire ropes from outside elements, so wire rope slings are free of rust when used to lift heavy materials.
All wire ropes should be properly maintained to extend their working life. Cable slings and wire cable cranes that pull wire ropes must be fitted with wire rope clips to prevent wire strand breakage.
