Abstract
A hoist for vehicles having two lifting columns arranged at both sides of a vehicle, each having two support arms that are supported in a horizontally pivotal and longitudinally adjustable fashion at their lifting column, and each having at their free end a support plate. These support plates are positionable at support positions underneath a vehicle as specified by the vehicle manufacturer by an appropriate movement of the support arm. The manufacturer support positions are saved as target positions according to corresponding vehicle model in a data memory of the hoist, and coordinates of actual positions of the support plates are determined by measurements and perhaps calculations. A computer makes a comparison between the target and actual coordinates, and enables a lifting process of the support arms only when differences between the target and the actual coordinates are within a predetermined tolerance.
