The present invention relates to a gondola lift having two parallel suspension haulage cables between which the gondolas hang. The two cable loops extend between two stations and each cable is driven by a direct current electrical motor, the two motors being identical and having separate excitation circuits. The armature windings are connected to the same power supply source by two armature circuits including identical resistors which provide an armature voltage drop and a reduction in speed for restoring identical power outputs of the two motors when one of the cables is in advance. The mechanical connections between the cables and the motors include gear boxes, the high speed shafts therefrom being coupled by a control clutch.
