Abstract

A winch with handheld battery powered tensioning and payout unit provides uniform loading of all winches and allows for safe easy loading and payout. A method and apparatus is provided for retrofitting manual winches, in particular manual marine winches, to be operable with a handheld battery powered tensioning and payout unit.

Abstract

A manual marine winch includes a winch housing; a rotating drum assembly supported on the housing; a winch line selectively spooled and un-spooled on the drum; a manually actuated control for spooling and un-spooling the winch line including a handle for selectively tensioning the drum and moveable between a position engaged with the drum for winch line tensioning and stowed position wherein the handle is not engaged with the drum; a tension holding mechanism comprising at least one ratchet gear coupled to the drum, at least one pawl selectively engaged with at least one ratchet gear to hold tension on the winch line, and a knockout configured to selectively disengage each of the pawls to allow for release of tension on the winch; and a biasing mechanism selectively engaged by the handle and configured to bias the handle toward the stowed position when the handle is engaged with the drum.

Abstract

A manual marine winch includes a safety loading handle and integrated locking dog release. The winch includes a handle for selectively tensioning and selectively releasing tension on winch; a tensioning ratchet gear coupled to the drum assembly for selectively tensioning the winch; a tensioning ratchet pawl mounted on the handle and selectively engaged with the tensioning ratchet gear for tensioning of the winch; at least one tension holding ratchet gear coupled to the drum assembly for holding tension on the winch; at least one locking dog pawl selectively engaged with each tension holding ratchet gear to hold tension on the winch; and a knockout member carried on the handle and configured to selectively disengage the locking dog pawls from the tension holding ratchet gears to allow for release of tension on the winch.

• B66D 1/06 - Safety cranks for preventing unwanted crank rotation and subsequent lowering of the loads

Abstract

A self-aligning roller chock comprises a deck mounting structure which includes a boss member coupled to the deck and a swivel base plate rotationally coupled to the boss member for rotation about an axis substantially perpendicular to the deck; a pivot assembly coupled to the swivel base plate; a frame coupled to the pivot member and configured to pivot relative to the deck mounting member about the pivot assembly; and a sheave wheel rotationally mounted within the frame adapted to receive rigging line therein. The chock will pivot about two axes providing a self-aligning horizontal and vertical alignment with a resulting force of the rigging line. The self-aligning roller chock may further include a spring coupled to the frame and partially supporting the weight of the frame and the sheave wheel at least when the axis of the sheave wheel is non-parallel to the plane of the deck.

Abstract

A manual marine winch includes a safety knockout override preventing release of winch tension without the handle in stowed position. The winch includes a housing; a rotating drum on the housing; a winch line on the drum; a control for spooling and un-spooling the winch line on the drum, wherein the control includes a handle for selectively tensioning the drum and moveable between a position engaged with the drum and a disengaged stowed position; a tension holding mechanism on the housing comprising a ratchet gear coupled to the drum, a pawl selectively engaged with the ratchet gear, and a knockout configures to selectively disengage the pawl from the gear to allow for release of winch tension; and a safety knockout override coupled to the housing and selectively engaged by the handle and configured to prevent release of winch tension when the handle is not in the stowed position.

Abstract

A manual marine winch includes a winch line including a wire rope, a pair of spaced side plates, a rotating spool assembly supported between the side plates and including a drum, wherein the drum defines a wire rope stacking space on the drum for storing a single stack of wire rope, and a manually actuated control for spooling and un-spooling the wire rope in the wire rope stacking space on the drum.
