Wire Rope 8X19S Features:

• 8-strand anti-rotation structure: The 8-strand symmetrical twisting design significantly reduces the rotation torque during operation, and reduces the self-rotation amplitude by more than 50% compared with the 6-strand rope. It is especially suitable for long-distance suspension or multi-turn traction scenarios to avoid the shaking of the hanging objects or the entanglement of the rope body.

• Westerly (S) strands are enhanced and wear-resistant: each strand adopts the Westerly arrangement of "1 center wire + 6 inner wires + 12 outer thick wires", and the outer layer is all thick steel wires. The wear resistance is 10%-15% higher than that of the Warinton (WS), which is suitable for working conditions with frequent contact with pulleys.

• High breaking force: Under the same diameter, the total steel wire cross-sectional area of the 8-strand structure is larger, and the breaking force is about 15% higher than that of 6×19S, which is suitable for medium and heavy loads of 30-80 tons. The steel core (IWRC) version can withstand higher impact loads.

• Even force distribution: 8 strands have more contact points with the drum/pulley, and the pressure per unit area is smaller, which can reduce local stress concentration and extend the service life under multi-layer winding or high-frequency retraction and release conditions.

• Moderate flexibility: Although the outer layer of thick steel wire accounts for a high proportion, the 8-strand design makes up for the rigidity and can be adapted to pulleys ≥20 times the rope diameter. The bending performance is better than the 8-strand compacted strand rope of the same specification, taking into account both wear resistance and rope winding flexibility.

Wire Rope 8X19S Typical applications:

• 8×19S wire rope is suitable for medium and heavy duty, multi-turn or wear and torsion resistance scenes with the characteristics of "8-strand anti-rotation, Westerly wear resistance, and high breaking force". Typical uses include:

• Lifting machinery: 30-80 ton truck crane main hook, crawler crane luffing mechanism, especially suitable for long boom conditions, reducing the rotation and shaking of the hanging objects; tower crane hoisting trolley traction rope, resistant to frequent friction with the pulley.

• Port operations: lifting ropes for small and medium-sized container quay cranes, grab traction systems for bulk terminal gantry cranes, outer thick steel wires are resistant to seawater corrosion and wear, and the 8-strand structure is suitable for multiple pulley steering.

• Mine hoisting: cage hoists for medium and deep mines (hoisting height 500-2000 meters), the steel core (IWRC) version can withstand heavy loads, and the anti-rotation property reduces the torsional stress when the drum is wound.

• Engineering traction: traction ropes for large equipment translation (such as bridge support installation), temporary knots for steel structure hoisting, high breaking force suitable for heavy loads, anti-rotation to avoid knotting during traction.

• Elevators and ropeways: traction ropes for heavy-duty freight elevators, load-bearing ropes for small and medium-sized passenger ropeways in mountainous areas, taking into account stable operation and wear resistance, and suitable for multi-wheel steering traction systems.
