ABSTRACT:
A winch includes hydraulically operated brake and clutch means which comprise part of a drive train supported by and located within a cavity defined by a housing. The drive train includes an output shaft located as the uppermost shaft of the drive train and including a portion extending through a wall of the cavity and axially into one end of a hollow, open-ended cable drum located exteriorly of the cavity and having one end rotatably mounted in a wall of the housing and having its other end rotatably mounted on the output shaft. Coupled to hydraulic fluid circuitry for conveying operating fluid to the brake and clutch means is a lubrication fluid circuit for supplying lubricating fluid to bearings supporting the cable drum and to bearings and other components of the drive train, the lubrication fluid circuit including the interior of the cable drum.
