Abstract (en)
[origin: WO2009016317A1] The present invention relates to a winch for pulling a cable (C), in particular a synthetic cable for manoeuvring a load. This winch (1) is composed of two motorized drums (3) each comprising an active cylindrical peripheral surface (5) equipped with several annular grooves (6), said cable (C) being intended to be wound around the two drums (3) according to a helical arrangement. In accordance with the invention, the motorized drums (3) 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 means (4) and comprising a cylindrical peripheral surface equipped with at least one of the grooves (6): 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 (11b, 11c) comprise at least one axial cylindrical extension, the cylindrical peripheral surface of which constitutes a rotational bearing for the central cylindrical surface of at least one of said other pulleys (11).
