Abstract

A winch comprises a capstan (2) provided with a plurality of circumferential grooves (11). The grooves (11) comprise a high friction material and the density of the material of each groove (11) is different, so that the coefficient of friction of the cable bearing surface increases from the load end to the tail end of the capstan (2).
