Wire Rope 6x37 Features:

• Better flexibility

Compared to 6x19 (19 steel wires in a single strand, with a thicker wire diameter), 6x37 has more single-strand steel wires and a thinner diameter (e.g., 16mm rope, 6x19 single-wire diameter is about 1.8mm, 6x37 is about 1.2mm), so when bending with a small radius (such as passing through a small pulley or drum), the bending stress distribution is more uniform, and the bending fatigue life is increased by 30%~50%.

• Good impact and vibration resistance

The multi-wire structure can absorb impact energy through slight deformation between steel wires, and is suitable for scenes with intermittent load fluctuations (such as elevator operation and crane luffing).

• More uniform surface contact

The outer layer has a large number of thin steel wires, a larger contact area with pulleys and drums, and reduced wear per unit area, which is suitable for working conditions that require frequent retraction and release (such as winches and elevator traction)

• Our wire ropes are fully tested: each batch of products is fully tested for 12 indicators including "breaking force, bending fatigue, torsion times, diameter deviation, appearance defects", etc., and is equipped with a "non-destructive flaw detector" rarely seen in the industry, which can accurately identify hidden defects such as internal broken wires and inclusions, with a factory pass rate of 100%.

Wire Rope 6x37 Typical applications:

• Based on its "medium strength + medium flexibility" characteristics, 6x37 wire rope is mainly used in the following scenarios:

• Elevator industry: as a traction rope (matching elevator special pulleys, the diameter is usually 8~12 times the rope diameter), it needs to meet the requirements of frequent starting and stopping and small radius bending (such as residential/commercial elevators, freight elevators).

• Small and medium-sized lifting equipment: such as auxiliary hooks and electric hoists of 10~50 tons truck cranes (the lifting height is high and needs to be frequently retracted and released).

• Lifting machinery: mine hoists (non-deep mines, lifting height ≤500 meters), material hoists for construction.

• Ropeways and cable cars: small passenger ropeways (operating speed ≤3m/s), traction or load ropes for freight cable cars.

• Agricultural and engineering machinery: tractor traction ropes, boom cables of excavators (need a certain degree of flexibility to adapt to the swing of the mechanical arm).
