Common Types of Steel Wire Ropes for Cranes
Wire ropes used in cranes are mainly multi-strand, high-strength, fatigue-resistant, and bending-resistant.
Main types
- Linear contact wire ropes
- Surface contact wire ropes
- Galvanized anti-corrosion wire ropes
- Compacted strand wire ropes (high-end, wear-resistant)
By Structure (Most Popular)
1.6×19 Classification
- Features: Rigid, wear-resistant, high tensile strength
- Applications: Hoisting, luffing, long-distance lifting
- Used for: Truck cranes, gantry cranes, port cranes
2.6×37 Classification
- Features: Flexible, good bending resistance, long fatigue life
Applications: Small drums, frequent lifting
Used for: Overhead cranes, electric hoists
3.18×7 / 18×19 Rotation-resistant Wire Ropes
- Features: Non-rotating, stable lifting, high safety
- Applications: Tower cranes, port cranes, high-altitude lifting
4.Compacted Strand Wire Ropes
- Features: High density, ultra wear-resistant, long service life
- Applications: Heavy-duty, high-frequency industrial use
- Used for: Heavy cranes, export to Europe & America
By Surface Treatment
- Bright (Uncoated) Wire Rope
- For indoor, dry environments
- Cost-effective, general working conditions
Galvanized Wire Rope (Hot-dip / Electro-galvanized)
- Anti-rust, anti-corrosion, salt-spray resistant
- For:
◦ Coastal and high-humidity areas
◦ Ports, docks, outdoor projects
◦ Export equipment (Indonesia, Brazil, USA)
Application Guide
- Overhead Cranes: 6×37, flexible, galvanized
- Electric Hoists: 6×37, high strength
- Gantry & Port Cranes: Rotation-resistant, galvanized
Truck Cranes: 6×19, wear-resistant
- Mining & Steel Mills: High temperature resistant, galvanized
Selection Tips
- Frequent lifting → choose flexible 6×37
- Outdoor/coastal → must use galvanized
- Heavy-duty working → choose compacted strand
- High-altitude lifting → choose rotation-resistant
- Small drum → choose more flexible rope
- Our Advantages for Export Equipment
- High-strength crane-grade wire ropes
- Hot-dip galvanized for corrosion resistance
- Good bending and fatigue resistance
- Suitable for harsh environments (humid, coastal, dusty)
- Comply with international standards for global markets
