Steel wire rope is a deep processed product with high carbon steel hot rolled wire rod as the primary material, which occupies an important position in the national economy, especially in mining, metallurgy, oil, coal, ocean transportation, forestry, ports, construction and other operations. In addition to being used for binding, towing and slings, it is mainly used for carrying people and objects in various forms of transmission and trekking equipment. It is widely used in planning, and its quality is directly related to industrial production and safety.
1. It can be divided into aerial ropeway, mine excavation, hoisting equipment, drilling well equipment, fishery, offshore facilities, elevators, aviation, etc.
2. According to the structure, it can be divided into single strand rope, multi strand rope and multi process wire rope.
3. According to the surface conditions, it can be divided into: smooth surface, galvanized (zinc alloy or other metal coating), coated (coated) plastic steel wire rope and compacted forging rope.
4. It can be divided into point contact, line contact and surface contact wire ropes according to the twisting characteristics (wire contact in strand).
5. It can be divided into round strand and special-shaped strand (such as triangular strand, elliptical strand and sector strand) wire rope according to the shape of strand section.
6. According to the lay method, it can be divided into: right cross lay (ZS), left cross lay (SZ), right co lay (ZZ) and left co lay (SS) wire ropes. There are also mixed lay (aZ or aS) wire ropes abroad.
7. According to the type of rope core, it can be divided into: wire strand core (IWSC), wire rope core (IWRC), natural fiber core (NFC) and synthetic fiber core (SFC) wire ropes.
