About this construction

How does 24W×7 compare to 18×7?

More strands in more layers means better torque cancellation, so 24W×7 holds a load steadier on a single-part line. It's also more flexible. 18×7 is the simpler, lower-cost option where rotation demands are moderate.
What does the W mean?

Warrington strand construction — a wire arrangement that alternates thick and thin wires in the outer layer, giving a better balance of fatigue and abrasion resistance than uniform wires.
Where does 24W×7 sit in the non-rotating range?

Between 18×7 and the 35-strand constructions. It suits tower cranes, mobile cranes, rotary drilling rigs and marine cranes where rotation resistance matters but lifting heights don't demand a 35-strand rope.
Should I consider the compacted version?

24W×K7 gives higher breaking force at the same diameter plus better drum crush resistance. If you're running multi-layer drums or need more capacity without changing sheaves, it's worth comparing.

Applications

More layers, steadier loads

Twenty-four Warrington strands in opposing layers cancel torque more completely than an 18-strand rope, so loads sit steadier on a single fall. Flexible enough for tower and mobile crane reeving, with fatigue resistance to match.

Manufacturing

Drawn, stranded and closed in-house

Every rope starts as Baosteel or Shagang wire rod and runs through our own servo-driven drawing and planetary stranding machines. German Fosser lubricant is applied at closing, and each rope is tensile tested against its declared breaking force before it ships.
