Abstract

Winch comprises a rotatable bearing surface for a cable and the friction between the surfaces and a given cable material at a predetermined tension varies continuously or stepwise along a rotational axis. Pref. the coefft. of friction of the surface for a given cable material increases grdually or stepwise along the axis. The surface pref. comprises a high friction material, and more pref. the material is polyurethane, polypropylene, or PVC.
