Its standard 6×37 construction—6 outer strands, each containing 37 wires (typically in Warrington-Seale lay)—delivers exceptional flexibility while maintaining reliable load capacity. Available in diameters from 5 mm to 60 mm, it offers tensile strength of 1570 MPa to 1960 MPa, complying with ISO 9001 and GB/T 20118 standards. The 37-wire strands (smaller wire diameter than 6×19 ropes) enable use with small pulleys (≥16× rope diameter), and the rope supports both fibre core (FC) and steel core (SC) options for tailored performance. This rope is ideal for dynamic applications like overhead cranes, elevators (light-duty), and entertainment rigging, where flexibility and fatigue durability are critical.

• 37-Wire Strand Advantage: 37 smaller wires per strand (vs. 19 in 6×19) enhance flexibility, allowing bending around pulleys as small as 16× rope diameter—perfect for overhead cranes with tight pulley systems.
• Warrington-Seale Lay: This lay pattern balances wire size (alternating small/large wires) to maximize metal fill factor (85%) while maintaining flexibility, reducing fatigue failure by 30% in high-cycle use.
• Fibre Core (FC): Reduces weight by 15% and enhances shock absorption, suitable for light-duty dynamic applications (e.g., entertainment rigging, small elevators).
• Steel Core (SC): Increases tensile strength by 20% and reduces elongation to ≤1.5%, ideal for medium-duty dynamic lifting (e.g., factory overhead cranes, delivery truck lifts).
6×37 (10-40 mm diameter, SC core) powers factory overhead cranes (for machine parts, assembly lines) and automotive production line hoists—its flexibility allows smooth spooling on multi-layer drums, and SC core resists heavy load elongation.
6×37 (5-16 mm diameter, FC core) is used in theater rigging (stage curtains, lighting) and residential small elevators (≤500 kg capacity)—its lightweight FC core and high flexibility enable precise, quiet operation (≤55 dB).
6×37 uses 37 smaller wires per strand (vs. 19 larger wires in 6×19), reducing wire rigidity and enabling bending around smaller pulleys—critical for dynamic applications like overhead cranes.
At 1770 MPa tensile strength, the 16 mm 6×37 (FC) rope has a minimum breaking load of 280 kN, suitable for 56 kN safe working load (5:1 safety factor) in theater rigging or small elevators.
Inspect every 4 weeks for wire fraying (focus on pulley contact points); reapply lubricant (every 3 months) to reduce friction—this extends service life by 25% in industrial overhead crane applications.
