Abstract: A vehicle repair rack having a platform for receiving vehicles for straightening is tilted as it is raised from the floor for easier loading of low vehicles, without the vehicle's bottoming out. The repair rack uses a parallel linkage to raise the platform. The platform is one link of the parallel linkage; and, the link that is parallel to the platform is allowed to elongate as the platform is raised, thereby causing the platform to move into non-parallelism with respect to the elongated link, so the platform is tilted. The parallel linkage includes legs as the other two links, and a connecting rod between the two legs is the elongating link. One end of the connecting rod has a slot that allows the connecting rod to move axially to a limited extent for the elongation.
