Abstract: A winch includes a rotary drum, a cable which can be wound on the drum in multiple layers, and a brake for braking the rotation of the drum, the brake being calibrated to permit the rotation of the drum beyond a variable torque which decreases as the length of the cable wound on the drum increases.

Abstract: A transfer device for limiting a twisting of a link between an end of the fixed link with respect to a fixed part and an end of the fixed link with respect to a revolving part that can revolve with respect to the fixed part about an axis of rotation, the transfer device for a link includes: a composite drum comprising a set of drums aligned on the axis of rotation about which the link can be wound, the set of drums comprising a fixed drum intended to be secured to the fixed part in rotation about the axis of rotation, a revolving drum intended to be able to revolve about the axis x with respect to the fixed part and a set of at least one loose drum interposed between the fixed drum and the revolving drum, each loose drum being free to rotate about the axis of rotation with respect to the revolving drum and the fixed drum and having a height on the axis.
