Zusammenfassung: | The invention discloses a parallel laid compacted strand steel wire rope for container equipment and a production method thereof. The lay pitch multiple of the steel wire rope is 6.0-6.8 times; the steel wire rope comprises a metal rope core; six first outer layer strands are arranged around the metal rope core; and the steel wire rope has a structure of 6*K36SFi+IWRC-28mm. The production method comprises the following steps of: calculating the diameter of the steel wire as a finished product and the diameter of the steel wire as a raw material; treating discs with the same diameter and different steel models and drawing the discs into the steel wires with corresponding diameters as the raw materials; thermally treating the steel wires as the raw materials and drawing the steel wires into the steel wires with corresponding diameters as the finished products; and twisting the steel wires as the finished products into outer layer strands and metal rope cores, wherein the outer layer strands adopt two compressio |
