ABSTRACT:
A multi-capstan winch has a pair of haulage capstans and at least one delivery capstan associated therewith. In delivering cable to the haulage capstans, the delivery capstan considerably reduces the loading on the cable, thereby allowing haulage capstans of a reduced diameter and weight. The delivery capstan is preferably coaxial with one of the haulage capstans, is a single groove capstan, has a relatively larger diameter than that of the haulage capstans, and has a cable wrap of greater than 180 degrees, but less than 306 degrees, preferably on the order of 220 degrees. Advantageously, the winch is driven by a chain of gears having the majority of the gears being mounted on shafts which lie substantially in a horizontal plane passing through the axes of the capstans.
