Abstract: The invention relates to a cable-based lifting device intended to move loads using multiple cables (1) coupled to an equal number peripheral grooves (2) provided in a single driving pulley (3). The invention comprises: a power unit (6) formed by a motor, a brake, a centrifugal brake and gear reducer, all mounted on a supporting shaft (7); a housing (8) which can be secured to the load to be lifted and in which the aforementioned supporting shaft (7) is housed; a structure (9) which can pivot in relation to the shaft (7) and in relation to the housing (8), said structure containing a pinion coupled to the output of the gear reducer of the power unit (6) and meshed with a toothed wheel (10) that rotates integrally with and concentrically to the driving pulley (3) about the shaft (5); and rollers (11).
