Winch (1) comprising a drum (2), a cable (6) which can be wound around the drum (2), means (7) for fastening the load (20) to the cable (6), a motor (3) with a motor shaft (4), a control (17) for the motor (3) that drives the motor shaft (4) to rotate in two opposite directions, and mechanical transmission means (5) for transmitting the rotational movement of the motor shaft (4) to the drum (2), said means (5) being configured so as to allow, in the state in which the motor shaft (4) is driven to rotate in a first direction D1, the transmission of the rotational movement of the motor shaft (4) to the drum (2) in the direction of winding the cable (6) around the drum (2). In the state in which the motor shaft (4) is driven to rotate in the second direction D2, the mechanical movement transmission means (5) are configured so as to not allow the transmission of the rotational movement of the motor shaft (4) to the drum (2), and at least part of these mechanical means (5) is configured to form, in this second operating mode, a brake preventing the drum (2) from being driven to rotate.
