ABSTRACT:
A winch has a final epicyclic reduction drive to its drum. The planetary gearing of the drive is borne in a web of the drum. Input to the final drive is via a ring driven either directly from a drive shaft or via reduction drive trains spaced axially from the final drive in the base of the drum. The drum may be of carbon-fibre material.
