Embodiment 1
[0022] like Figure 1-Figure 5 As shown, a high load-bearing steel wire rope for hoisting is formed by twisting six outer strands 1 symmetrically wrapped around a metal core, and the metal core includes a twisted metal core central strand 3 and a metal core outer strand 2. The outer layer strand 1 is a compacted strand of the Silu-Valenton composite structure, and the outer layer strand 2 of the metal core and the central strand 3 of the metal core are point contact structures.
[0023] The outer layer strand 1 is a compacted strand formed by twisting a central steel wire with 30 steel wires of 3 different diameters in total, and is in the form of a Siru-Walington composite structure.
[0024] The outer strands 2 of the metal core and the central strand 3 of the metal core are twisted by 6 steel wires wrapped around one central steel wire, and are in a point contact structure.
[0025] Its preparation method is:
[0026] On the stranding car, the steel wires are arranged thr...
