About this construction
Why 35 strands?
More strands in more opposing layers means more complete torque cancellation. 35W×7 is the most rotation-resistant construction in the range, which is what you want on a long single-part lift where the load has nothing to stop it turning.
Why does the range start at 18 mm?
Fitting 35 strands into a smaller diameter makes each strand very fine and fragile. Below 18 mm the 18-strand and 19-strand constructions do the job better.
Is it as strong as a 6-strand rope?
Not at the same diameter. Dividing the steel across more strands costs some breaking force, and you're buying rotation resistance and flexibility with it. If you need maximum force as well as rotation resistance, look at the compacted 35W×K7.
How does it compare to 35W×K7?
35W×K7 has compacted strands, so it carries more load at the same diameter and resists drum crushing better. 35W×7 is the standard-strand version, and the sensible choice where those gains aren't worth the cost difference.
Selecting 35-strand rope
Maximum rotation resistance
Thirty-five Warrington strands in opposing layers cancel torque more completely than any other construction we make. It's the rope for long single-part lifts on tower cranes, mobile cranes and drilling rigs, where a spinning load is a hazard rather than an inconvenience.
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.
Ordering
Cut, reeled and shipped to spec
Reels run to 3,000 m, with custom lengths cut to order. Every shipment carries a mill certificate and test report, packed for sea freight and shipped CIF from the Yangtze Delta.
MOQ 1,000 m, negotiable.
