A device for automatically moving vehicles along guide ways of lifts is constituted by a pusher carriage movable horizontally with a corresponding actuator on a guide that is longitudinally fixable to at least one of the guide ways and is provided with at least one pair of arms that are articulated thereto and rotate in a scissor-like fashion on a horizontal plane flush with the upper resting surface of the guide way, from an active position, in which they are parallel one another and adjacent to at least one wheel and lie transversely above the wheel, to an inactive position, in which they are divaricated and aligned parallel to the wheel.
