Abstract: A winch (1) for pulling a cable (C) for maneuvering a load is composed of two motorized drums (3) each including an active cylindrical peripheral surface (5) equipped with several annular grooves (6), the cable intended to be wound around the two drums (3) according to a helical arrangement. The motorized drums are each formed from at least three pulleys (11), that can each be rotated around a common central axis (10), cooperating with their own dedicated motor element (4) and including a cylindrical peripheral surface equipped with at least one of the grooves: two pulleys known as outer pulleys (11a, 11d), positioned between which is at least one pulley known as a central pulley (11b, 11c). The central pulleys include at least one axial cylindrical extension, the cylindrical peripheral surface of which constitutes a rotation bearing for the central cylindrical surface of at least one of the other pulleys.
