6 mm diameter steel wire rope, taking the commonly used 6*19 structure as an example, has a strength level of 1570MPa, the lowest breaking tension of hemp core is 18.7 kN, about 1.9 tons, and the minimum breaking strength of steel core is 20.1 kN, about 2.05 ton. The safety factor is 6, and the maximum lifting capacity of a single rope is 340 kg. If there is a moving pulley or a high-strength steel wire rope is used, the lifting capacity can be increased.

A steel wire rope is a spiral steel wire bundle in which steel wires with mechanical properties and geometric dimensions that meet the requirements are twisted together according to certain rules. The steel wire rope consists of steel wires, rope cores and lubricants. lipid composition. A steel wire rope is first twisted into strands from multiple layers of steel wire, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. In material handling machinery, it is used for lifting, pulling, tightening and carrying. The steel wire rope has high strength, light weight, stable operation, not easy to break suddenly, and reliable operation.
The main function of the rope core is to support the steel wire rope to achieve a stable cross-sectional structure. The rope core includes steel core and fiber core. The fiber core includes natural fiber core and synthetic fiber core. Natural fiber core such as sisal, jute, cotton thread, etc., and synthetic fiber core includes polyethylene and polypropylene filament, etc. The natural fiber core can store more grease, lubricate the wire rope and extend the service life of the wire rope.
