Abstract
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(a-) 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.
