MBF = minimum breaking force at the stated wire tensile grade (N/mm²). Weights are nominal. Compacted rope is supplied with a steel core; the plastic-injected option adds a polymer layer between the outer strands and the core. Diameters outside 6–80 mm and non-standard grades are manufactured to order — request a quote.
About this construction
How does 8×K26 compare to 6×K36?
Similar breaking force at most diameters, but 8×K26 is more flexible and suits smaller sheaves. 6×K36 holds up slightly better against pure abrasion. Choose by sheave diameter and reeving, not by strength.
This range starts at 6 mm — what are the small sizes for?
Where the rope bends hard and often: small sheave diameters, multiple falls, high cycle counts, tight reeving on compact machines. Flexibility buys fatigue life in exactly those conditions.
Do I need the plastic-injected version?
On multi-layer drums and continuous-duty cranes, usually yes — it reduces internal wear and holds lubricant, which extends service life. For single-layer or lighter duty the standard steel core is fine.
Why compacted 8-strand rather than 6-strand?
Eight strands bend more easily at the same diameter, and compacting them adds back the breaking force and surface hardness that 8-strand normally gives up. It's the combination most crane makers want: flexibility without the usual penalty.
Applications
Flexibility and strength in one rope
Eight compacted strands give a rope that bends easily enough for tight reeving while carrying the load of a compacted 6-strand. It's why 8×K26 turns up across the widest range of cranes we supply — overhead, port, metallurgical, mobile and marine.
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.
