Abstract
A manual marine barge winch includes a housing, a winch-line holding drum mounted for rotation on the housing, a winch-line coupled to the drum and adapted to be wound onto and off of the holding drum to tension and pay out the winch, a drum drive for rotating the drum to tension and to pay out the winch line, and at least one winch-line engaging roller adapted to engage the winch line at least during tensioning of the winch. Preferably at least one of the winch line engaging rollers is a powered or driven roller for driving the winch line.
Claims19
A manual marine winch comprising:
- a housing;
- a winch-line holding drum mounted for rotation on the housing;
- a winch-line coupled to the drum and adapted to be wound onto and off of the holding drum to tension and pay out the winch;
- a drum drive for manually rotating the drum to tension and to pay out the winch line, wherein the drum drive includes a drum gear attached to the holding drum and a drive pinion engaging the drum gear and a manual rotation input mechanism coupled to the housing for selective operation by the user, wherein manual operation of the manual rotation input mechanism rotates the drum gear through the drive pinion;
- a first winch-line engaging, driven roller adapted to engage and drive the winch line at least during tensioning of the winch wherein the winch-line engaging roller is coupled to and coaxial with the drive pinion;
- a second winch-line engaging, driven roller spaced circumferentially along the drum from the first winch-line engaging, driven roller and adapted to engage and drive the winch line at least during tensioning of the winch;
- and
- a driven gear co-axial with the second winch-line engaging, driven roller spaced circumferentially along the drum gear from the drive pinion.
