ABSTRACT:
A method of operating a winch having a winch drum mounted in a housing to reel in and pay out the cable over a plurality of repeated cycles of use during a period of use of the winch. A digital counter is mounted on the housing so as to be responsive to each rotation of the drum in both directions and arranged to generate a total count during the period of use which is indicative of the number cycles so that the winch can be taken out of operation for service when the number of rotations reaches a predetermined maximum. The digital counter includes a follower contacting a raised portion on an edge of the drum so as to be moved by the raised portion for actuating each count of the digital counter.
