The four-strand non-rotating steel wire rope of the truck crane comprises a non-rotating steel wire rope body, the non-rotating steel wire rope body is composed of four outer-layer strands and a rope core, the four outer-layer strands which are independently compacted and the rope core are twisted and forged to form the non-rotating steel wire rope body, and the rope core is composed of a spring type inner core and a hemp core layer. And the hemp core layer is wrapped outside the spring type inner core. According to the non-rotating steel wire rope, the non-rotating steel wire rope body is composed of the four outer layer strands and the rope core, the outer layer strands are composed of the outer steel wire layers and the inner steel wire layers, the twisting rotation directions of the outer steel wire layers and the inner steel wire layers are opposite, the twisting rotation direction of the non-rotating steel wire rope body is opposite to the twisting rotation direction of the outer steel wire layers, and the twisting directions of the multiple layers are opposite. According to the non-rotating steel wire rope structure principle, the load is shared by the inner-layer and outer-layer stranded ropes, the safety coefficient of the steel wire rope is increased, and the service life is greatly prolonged.
