Abstract
An improvement to lifting devices where a service cable 1 and hoist rope 2 are wound around one another, wherein the load-bearing rope 2 is wound around the cable 1 that is paid off from a cable winch 13 so that when the wound cable and rope 2 leave the device, the higher tension on the rope pulls that into an axial configuration with the service cable 1 helically coiled around it.
