A portable, lightweight, and low relief profile turntable is equipped for the universal mounting of different winches and winch-type apparatus suitable for use on the deck of a ship or other surface. The turntable is capable of mounting to an increased number of potential locations on deck where it may be easily manipulated to achieve a useful direction and an optical fleet angle.

The invention is an extendable winch assembly, that include a winch, having a drum for winding and unwinding a line and a first motor for driving the drum about a winding axis. The assembly also includes a winch mount for mounting the winch to a vehicle, the winch mount. The winch mount includes a base attached to the vehicle and extendable arm attached at one end to the base, wherein the extendable arm is configured to move the winch from a retracted position proximate the vehicle to an extended position spaced from the vehicle. The winch mount also includes a plate attached at an other end of the extendable arm, wherein the winch is attached to the plate in such a way as to allow the winch to pivot about a pivot axis perpendicular to the winding axis.

A winch is described that includes a drum, a motor and transmission, and a tensioner. The motor and transmission apply torque to the drum, thereby enabling the drum to draw in and let out a line. The tensioner is positioned adjacent to the drum, such that when the line passes between the tensioner and drum, the line is in frictional contact with the tensioner and drum. The tensioner rotates with a linear speed exceeding a linear speed of the drum as the line is let out from the drum, and rotates freely as the line is drawn onto the drum. Methods for making and using the winch are also described.

The present disclosure presents a webbing take-up device, which comprises: a spool; a lock section that is restricted from rotating at a time of a vehicle emergency so as to limit rotation of the spool in the pull-out direction; a force limiter mechanism that permits rotation of the spool in the pull-out direction at a force limiter load or greater when rotation of the spool in the pull-out direction with respect to the lock section is being limited; a switching member that switches a load value of the force limiter load by switching between a rotation-restricted state and a rotation-enabled state; and a mounting member that includes a switching member mounting section at which the switching member is disposed, and a restriction section that is engaged with the switching member so as to restrict displacement of the switching member disposed at the switching member mounting section.

A rope guiding device used in connection with the rope hoist to guide a hoisting rope. The inventive rope guiding device of a rope hoist for guiding a hoisting rope on a rope drum which rope drum may be adapted to rotate in order to wind the hoisting rope around the rope drum or off the rope drum to hoist and lower a load adapted on the hoisting rope, the rope guiding device comprising at least one guiding element to guide the hoisting rope of the rope hoist, and a screw to move said at least one guiding element, is characterized in that wherein the rope guiding device is supported to the body of a trolley of the rope hoist by means of a support arrangement which support arrangement comprises first pivotings and second pivotings adapted to a substantially 90-degree angle in relation to said first pivotings.

A winch for a power generating system using a tethered airborne device, the winch comprising a drum rotatable about its main axis a guiding apparatus arranged to guide an airborne device tether to wind and unwind around the drum; wherein the drum is rotatable relative to a pivot point to move in a first plane and the guiding apparatus is disposed relative to the drum to move along part of an orbital path around the drum in a second plane substantially perpendicular to the main axis of the drum, thereby allowing alignment of the winch with respect to an unwound length of the tether.

A bell design crown block for a top mounted compensator includes a removable, tilting sheave block mounted within the outside perimeter of a crown block yoke. An actuator installed in the crown block actuates the tilt function. No hinge adaptor is required and the sheave block does not hang past or below the crown block yoke. When used in a floating platform application, idler sheaves are mounted on the crown block yoke and an optional interface beam may be provided for the active heave cylinder head.

A hoisting system for hoisting a load relative to a body includes a hoisting cable, a hoisting mechanism selectively operable to deploy and retract the hoisting cable, and a guide mechanism movably mounted to the body at a position between the body and the hoisting cable. The guide mechanism includes at least one locking device that selectively locks the guide mechanism against movement in a first direction.

A system and method for a load-facing winch are described for hauling or lifting loads at least 30 from center of the primary support object. The load-facing winch includes a winch-mount that includes a housing, a center-pivot, a mounting-plate, and a plurality of springs. The mounting-plate is attached to the winch and tilts and/or turns about the center-pivot, which allows the winch to face the load. By directing the winch to face the load, angular resistance against a moving fairlead may be reduced.

A multi-functional system for the self-recovery of a wheeled vehicle. The system includes: a dished adaptor plate permanently fixed to a driven wheel of a vehicle by capturing beneath the wheel retaining bolts or nuts; a drum plate driven in rotation directly by the adaptor plate or indirectly via a driven plate driven in rotation by the adaptor plate and by a torque-transmitting appliance situated between the driven plate and the drum plate; complementary attachment elements provided on the drum plate and the drum permitting the rapid attachment of the drum to the drum plate; a tow cable fixed to and wound around the drum and led off to a secure anchor point such that subsequent driving of the wheel in the appropriate rotational sense applying tension to the tow cable, thereby assisting in recovery of the vehicle.
