The invention relates to a winding, particularly a winch, arrangement (100) comprising a two speed manually operable winding member (10) and a drive unit (20) comprising a motor (21). The drive unit (20) comprises a transmission arrangement connected to a motor shaft (25), an outgoing shaft (22) with an outer gear wheel (23). The transmission arrangement is adapted to allow the outgoing shaft gear wheel (23) rotate in the same direction but at different speeds depending on rotational direction of the motor (21). The manual winch (10) is adapted for reception of the outgoing shaft (22) allowing the winch drum (1) to be motor (21) driven. The drive unit (20) comprises means (67,68) allowing engagement/disengagement of the outgoing shaft gear wheel (23) from the manually operable winding member (10) and the winding arrangement can be used as a two-speed manual or a two speed motor driven winding arrangement.

The invention describes a winch for nautical use or for devices for lifting and lowering on a rope, comprising a fixed stator body and a rotor body fixedly connected to the stator body. The rotor body is able to rotate around a longitudinal axis to wind a rope on its outer surface. The winch is provided with a self-tailing device in turn comprising two half-pulleys, a lower half-pulley and an upper half-pulley, 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 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 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.

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-1) 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.

A power assist system for a manually operated winch includes a winch having a central winch shaft, an electric motor with a drive shaft and a motor control unit, a winch handle adjusted for manually operating the winch, and a control input device. The electric motor and the drive shaft are connected to the winch and the central winch shaft through a connection module placed below said winch. The winch handle is arranged to temporarily and mechanically connect with an upper end of the central winch shaft to allow manual operation of the winch. The control input device includes one or more electronic unit(s), built into, or mounted onto said winch handle. The control input device is further arranged to send wireless control signals through radio transmitter and receiver to the motor control unit. The wireless control signals are arranged to be temporarily but uniquely linked to the motor control unit to selectively control the winch that the winch handle is temporarily connected to. The control input device is adjusted to send different wireless control signals to the motor control unit depending on the direction the winch is manually operated in. The winch handle is adjusted to generate and/or store the energy needed to operate the control input device.

A power-assisted winch includes a rotatable drum for receiving a line thereabout. The power-assisted winch further includes a trigger mechanism configured to be releasably engaged upon a force exerted on the line. The trigger mechanism selectively activates a power source providing power to the winch to assist with hauling the line when engaged.

A winch handle (10, 20) locking system comprising a winch handle (10, 20) with a bit (11, 22) adapted to mate with a socket (11, 12) in a winch (10). The bit (11, 22) employs a first magnetic member, a magnet guide (23), interacting with a second magnetic element, a permanent magnet (12), inside the socket (11, 12). The magnet is fixed to the winch (10) at a position allowing the winch handle bit (22) to mate with the socket (11, 12) and securing a desired attraction force between the winch (10) and the winch handle (10, 20). Furthermore, a magnetic sensor (25) is placed at the magnet guide (23) in the bit (11, 22) and sends a trigger signal to electronics in the winch handle (10, 20) when the bit (11, 22) is fully mated into the socket (11, 12). An NFC antenna (24) in the bit (11, 22) is tuned to pick up a unique signal from an NFC tag (14) inside the socket (11, 12) of the winch (10) to allow the electronics in the winch handle (10, 20) to uniquely control a motor connected to the winch (10).

The invention relates to a winding, particularly a winch, arrangement (100) comprising a two speed manually operable winding member (10) and a drive unit (20) comprising a motor (21).
