Abstract:

Apparatus and method for straightening the bodies and frames of automobiles and other vehicles. The apparatus includes a bench having a low profile with retractable lifts which permit the bench to be positioned substantially flat on the ground so that a vehicle can be driven over it. The vehicle can then be raised and lowered with the bench, as required. The vehicle is secured to the bench, and a puller which can be adjusted about both horizontal and vertical axes is connected to the bench and the vehicle for pulling on desired portions of the vehicle. Both the puller and the means for securing the vehicle to the bench are attached to the bench with wedges which enable them to be removed and repositioned, as required.
