Steel Wire Rope Construction | Description | Common Applications | Alternative Suggestions |
6×19 Filler (6×25 Fi) |
Contains 6 strands with 19 or 25 wires each. Known for its flexibility and moderate resistance to wear. | Derrick and boom cranes, tower crane hoists, dredger boom hoists, and drilling rigs | Consider 6×36 for greater flexibility and fatigue resistance in applications that need endurance. |
6×36 | Made of 6 strands with 36 wires each. Highly flexible with strong fatigue resistance, but less abrasion-resistant. | Derrick and boom cranes, tower cranes, dredger ladder hoists |
Use 6×19 Filler if you need more abrasion resistance. This option is slightly stiffer. |
18×7 |
Features 18 strands with 7 wires each. Offers excellent rotation resistance. | Tower crane hoists, cranes with high lifting requirements | Substitute with 19×7 for similar rotation resistance if extra stability under load is needed. |
19×7 | Built with 19 strands of 7 wires each. Provides high rotation resistance, often used to minimize twisting. | Tower crane hoists, cranes where anti-rotation is essential |
Try 18×7 as an alternative for moderate rotation resistance needs. |
6×19 Seale |
A single layer of larger outer wires provides higher resistance to wear with moderate flexibility. | Drilling rigs, heavy-duty applications | Consider 6×36 if you prioritize flexibility and fatigue life over abrasion resistance. |
6×7 Galvanized | 6 strands of 7 wires, typically galvanized for corrosion protection. | Sand coring, swabbing, and marine applications |
For added durability, consider a plastic-coated option to improve corrosion resistance. |
6×21 Filler | Often has 6 strands with filler wires, usually left-hand lay, offering moderate flexibility and abrasion resistance. | Percussion drilling rigs |
Use 6×25 Fi or similar constructions for slightly better fatigue resistance. |
6×21 Seale |
Similar to 6×19 but with slightly higher wear resistance due to the Seale arrangement. | General lifting, cranes | Use 6×36 for more flexibility and fatigue resistance if needed. |
6×36 Filler Wire | High-flexibility construction with 36 wires per strand, ideal for environments needing strong endurance against bending fatigue. | Heavy lifting, hoisting, and high-flex applications |
For higher wear resistance, try 6×19 with slightly less flexibility. |
7×19 |
7 strands with 19 wires each, providing excellent flexibility, often used for smaller-diameter ropes. | Small pulleys, winches, control cables | Use 6×19 or 6×36 for larger applications that need similar flexibility. |
Rotation-Resistant Ropes (e.g., 35×7) | Designed to resist rotation under load, with multiple strands that minimize twist. | Cranes, hoisting applications with strict rotation control |
18×7 or 19×7 offer good rotation resistance for less demanding needs. |
