Anti Rotation Series Wire Rope

Product Overview

Anti-rotation (rotation-resistant) wire ropes feature multi-layer strand construction with opposing lay directions, preventing rotation of the load under single-line lifting. Essential for crane main hoist and mobile crane applications.

 

Construction & Design

Multi-layer construction with 2 or 3 strand layers. Outer layer laid in opposite direction to inner layer(s), creating a torque-balanced design that resists rotation. Available with FC or IWRC core.

 

Key Features

• Torque-balanced — prevents load rotation
• Multi-layer counter-rotation design
• Essential for single-line free lifting applications
• Available in 2-layer (17×7, 18×7) and 3-layer (35W×7) constructions
• Higher breaking force compared to same-diameter standard ropes
• Compliant with GB/T 20118, GB/T 8918, ISO 2408, EN 12385 standards
