摘要： A retractable warping winch with a supporting housing, adapted to be stably fixed to a deck of a vessel at an opening thereof, and a bell, including a base and a drum integral to each other. The bell is movably supported by the housing so that it can vertically shift therein between an extracted working position and a retracted rest position. The winch also includes a driving mechanism to rotate the bell, including a motor and a transmission. The driving mechanism includes a drive hub mounted in the housing. The base of the bell is mounted in the drive hub to be rotatably integral therewith and free to axially shift with respect thereto. The drive hub is mounted in the housing to be rotatably free and axially constrained thereto. The motor is mounted on the housing, externally and laterally thereto.

摘要： 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.
