About this construction

How does 19×K7 compare to 18×7?

Same job, more capacity. Compacted strands raise the breaking force at every diameter and improve resistance to drum crushing. 18×7 is the lower-cost option where you don't need either.
Is it as rotation-resistant as 35W×K7?

No. Nineteen strands cancel less torque than thirty-five. For long single-part lifts at height, step up to a 35-strand construction. 19×K7 suits moderate lifting heights where you also want strength and abrasion resistance.
Can I use it on a multi-layer drum?

Better than most rotation-resistant ropes. The compacted outer surface spreads pressure instead of concentrating it on the wire crowns, which is exactly what multi-layer spooling punishes.
Which constructions are included?

19×K7, 19×K19S and 19×K26S. They share diameter and breaking force but differ in wires per strand — tell us your sheave sizes and duty cycle and we'll recommend one.

Selecting 19-strand compacted rope

Rotation resistance with more steel

Compacting the strands puts more metal into the same diameter, so 19×K7 carries noticeably more load than 18×7 while keeping the opposing-layer construction that stops a load spinning. At 30 mm, 1960 grade, that's 653 kN against 547 kN for fiber-core 18×7.

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.
