The utility model discloses an elevator steel wire rope with a polyurethane coating, and provides a steel wire rope. The status of friction between the surface of the steel wire rope and a traction sheave can be improved, the abrasion resistance of the steel wire rope can be improved, and the service life of the steel wire rope can be prolonged. The steel wire rope comprises a steel wire rope core and rope strands, wherein the polyurethane coating with a thickness of 1 to 2mm is arranged outside the rope strands; the steel wire rope core has an 8*19S+8*7 structure; and each rope strand has a 1*19W structure. According to the steel wire rope, due to the arrangement of the polyurethane coating on the surface of the steel wire rope, when the steel wire rope contacts with a rope groove of the traction sheave, the abrasion of the steel wire rope to the rope groove of the traction sheave is reduced, and the abrasion resistance of the steel wire rope can be improved; a polyurethane material has self-lubricating performance, so that the steel wire rope is not required to be lubricated and maintained when being used, and is convenient to maintain. As the 8*19S+8*7 structure and the 1*19W structure are adopted for the steel wire rope, compared with an ordinary steel wire rope with the same diameter and an 8*19S+NF structure, the steel wire rope has the advantage that the fatigue using effects can be improved by over 40 percent during use.
