Abstract:
A power assist system for manually operated winches, including an electric motor (40), a motor controller (42), and a winch handle (20) with a radio module (46), enabling wireless communicating to the motor controller (42). The system is suitable for mounting onto winches (10) that has a shaft (11) accessible from the underside, typically through the deck of a sailboat. The motor (40) supplies additional turning force to the winch (10) to assist the manual operation. Sensors (31) in the winch handle measures the amount and direction of manual force and send it wirelessly to the motor controller (42) to control the motor (40). The radio signals (48) sent to the motor controller (42) has a unique address corresponding to the winch (10) it is connected to. The unique address is picked up by reading an NFC tag (13) on the winch. When the winch handle (20) is removed from the winch (10), the address is deleted, preparing the handle (20) for use on a different winch.
Abstract:
A cable winch (20) is described comprising: a hollow shaft gear-motor (1) operatively connected to at least one transmission arm (7); a load cell for fine reading of said driving torque; a toothed axis (10) supported by a first bearing support device (8) and by a second bearing support device (9); a driving pulley (2) comprising a groove for passing a suspension cable inside it; a guide element (11) of the cable; a cable puller element (5) for extracting the suspension cable from the throat; a trolley (6); a container consisting of a first containing element (3) and a second containing element (4); wherein the traction force is ensured by the friction of the cable in the groove of the driving pulley (2) and by the pressure exerted by the trolley (6) which, by means of at least one spring and a plurality of idle wheels, pushes the suspension cable against the walls of the throat.
Abstract:
A vertical transport apparatus includes a housing, a motor supported by the housing, a first drum, a second drum, and a tensioning control assembly. The first and second drums are operatively coupled to the motor and positioned to rotate relative to the housing. The first and second drums are positioned to enable rope to move therearound so that the housing can selectively ascend or descend along the rope. The tensioning control assembly is engaged with the rope to maintain the rope engaged with the first and second drums.
Abstract:
A mooring post unit is provided with a cable holding device on top of the mooring post. The cable holding device has a first pulley wheel, a second pulley wheel and a cable clamp, arranged to guide a mooring cable from a ship over the first pulley wheel to the clamp, back and forth via the second pulley wheel. A hydraulic force limiter is coupled between the second pulley wheel and the mooring post. The hydraulic force is expandable and compressible in the direction of a force exerted by the axis of the pulley wheel. The hydraulic force limiter temporarily gives way when a peak in the force exceeds a threshold. The clamp comprises a pair of drums, around which the mooring cable runs back and forth. By synchronously rotating the drums, the mooring cable may be hauled in or paid out under stress.

Le cabestan comprend un ensemble fixe (1), une poupée (2) guidée en rotation autour d'un axe vertical (ΑΑ') et une transmission de mouvement circulaire et de couple d'entraînement (4), en relation d'entraînement avec la poupée (2) et avec un axe central (3). L'ensemble fixe (1) comprend une platine horizontale (10), un arbre de guidage (12), recevant des paliers (130) de la poupée (2) et comportant une embase (120) montée en fixation sur des éléments cylindriques (11), rigidement fixés à la platine. La transmission de mouvement (4) est du type cycloïde et comprend au moins un étage de transmission réducteur formé d'un élément d'entrée (41), entraîné par un organe (30), et d'un élément de sortie (42), en relation d'engrènement avec la denture de l'élément (41) et avec la poupée (2), la denture de l'élément (41) et la denture de l'élément (42) étant formées d'une succession d'éléments de denture en nombre différents pour réaliser une réduction.
Abstract:
Treuil (1) à adhérence comprenant au moins un bâti (2), une poulie (3) montée sur ledit bâti (2), ladite poulie (3) comprenant un axe (4) et une roue (5) munie d'une gorge (6) périphérique externe pour la réception d'un câble, des moyens (7) d'entraînement en rotation de ladite roue (5) et des moyens (15) de maintien par appui du câble à l'intérieur de la gorge (6) de la roue (5).

Abstract:
The invention describes a winch (1) for nautical use or for devices for lifting and lowering on a rope, comprising a fixed stator body (2) and a rotor body (3) fixedly connected to the stator body. The rotor body is able to rotate around a longitudinal axis(a-l) to wind a rope on its outer surface. The winch is provided with a self -tailing device (6) in turn comprising two half -pulleys (61, 62 ), a lower half -pulley (61) and an upper half -pulley (62 ), mounted opposite one another and coaxial to the rotor body. The two half -pulleys, at the upper portion of the outer surface of the rotor body, define a circumferential throat (63) intended to at least partially house a winding of the rope. One half -pulley is fixed with respect to the rotor body and the other half -pulley is moveable parallel to the longitudinal axis to vary the dimensions of the circumferential throat. Advantageously, the winch comprises a device (8 -11) for adjusting the position of the mobile half -pulley along the longitudinal axis; the adjustment device is able to be activated by the user in real time and in all conditions of use of the winch.
Abstract:
The instant invention concerns a proceeding and an arrangement in connection with a winch for a sheet or a halyard on a sailing boat. This is, besides for sheeting-in, constructed to also allow veering-out of sheet or halyard rope arranged thereon by means of means that normally otherwise are intended for sheeting-in, more precisely a crank possibly having an appurtenant transmission integrated in the winch or the corresponding motor drive and appurtenant transmission, for driving of a drum belonging to the winch and a self-tailing unit arranged at the upper end of the same. The last-mentioned one has upper and lower rope guide rings as well as means in the form of an expedient arm for directing the rope into and out of the self-tailing unit in a controlled way. The invention embraces suspension and spring-mounting means for at least one of the rope guide rings that are arranged in such a way that this/these obtain(s) a mutually static and dynamic motion pattern. This pattern is such that, in connection with forcing apart the rope guide rings somewhere along the periphery thereof, for instance, by the arrangement of a rope between the same, the corresponding opposite portions of the rope guide rings automatically approach each other, for clamping of the rope arranged therebetween.
