A pair of beams or rails extend between the supports and are simultaneously raised and lowered for elevating an automobile supported on a pair of tracks spanning the beams or rails. The tracks are movable toward and away from each other to accommodate vehicles of different width. There are provided devices for moving one of the rails relative to the other. The moving devices comprises a rack on each of the rails, a pair of pinions carried by the rails in engagement with the racks, devices interconnecting the pinions for simultaneous movement and devices for rotating the pinions.
