Non-Rotating Wire Rope: Introduction and Applications

What is Non-Rotating Wire Rope?

Non-rotating wire rope, also known as rotation-resistant wire rope, is a specialized type of wire rope designed to minimize or eliminate the rope’s tendency to rotate under load. This is achieved through a unique construction of multiple layers of strands, where the outer and inner layers are wound in opposite directions. The torque generated by one layer is counteracted by the torque of another, resulting in exceptional stability during lifting operations.

Construction Features

Non-rotating ropes typically have two or three layers of strands. Common configurations include:

• 35WXK7: A 35-strand, multi-layer design with 7-wire strands per layer, offering superior rotation resistance and flexibility.

• 19X7: A basic two-layer rope, used in general lifting operations but with lower rotation resistance than 35WXK7.

• 18X7+IWRC or 19X19: Mid-tier options providing balance between rotation resistance and strength.

For added performance, these ropes can be:

• Plastic-coated (EPIWRC) between core and outer strands to reduce internal wear.

• Galvanized for enhanced corrosion resistance in marine or outdoor applications.

• Compacted to improve strength and smoothness.

• Lubricated during manufacture to extend service life.

Key Advantages

• ✅ High rotation resistance – ideal for single-line lifting and high-lift operations.

• ✅ Reduced risk of rope spinning or load rotation – improves safety and load control.

• ✅ Excellent flexibility and fatigue resistance, especially in high-cycle applications.

• ✅ Longer service life due to improved internal structure and materials.

Typical Applications

Non-rotating wire ropes are used in critical lifting scenarios where stability and safety are paramount:

• Tower cranes

• Mobile cranes

• Overhead cranes

• Offshore and marine winches

• Elevators

• Hoisting in mines and deep shafts

• Rotary drilling rigs
