The intricacies of the structure and specifications of wire ropes can be confusing because of all the different options available. Regardless of the difference between final wire ropes, four main components make up the foundation for all rope specifications. Call us if you are looking for world-class rigging supplies.
- Cores make up the center of the rope, and it is usually constructed from natural fibers, synthetic fibers, and steel that are designed to support strands. Cores significantly improve the overall strength of wire ropes while also providing anchors to keep strands in position while the rope is experiencing stress from loading and unloading.
- Wire that surrounds a core is typically constructed from materials like:
- Bronze wire rope
- Steel wire rope
- Stainless Steel wire rope
- Iron wire rope
When choosing materials, engineers must also consider that material grades in different sizes deliver a range of strength for final ropes (curve/fatigue, wear/corrosion).
- Strands of two or more wires are twisted in specific patterns to form strands. Strands lay around the core typically in helical or spiral patterns. Wires with smaller diameters are more flexible than larger wires. A large wire is ideal when resistance to abrasion is an essential characteristic.
- Lubrication is an essential component of wire ropes. Think about what would happen to a car without any oil or lubricant, and then think about what your wire rope would experience under similar circumstances. Common lubricants include:
- Foams
- Minerals
- Petroleum gas
- Grease
Lubrication reduces friction as wires move across one another and external elements.
