ABSTRACT:
A vehicle repair and alignment apparatus for correcting and aligning misshapened vehicle frames and outer body panels comprises a frame having a pair of elongate track members with slotted rails provided along the outer edges thereof, vertical pull towers pivotably mounted on a respective semicircular platen slidingly engaged on each rail enabling selective angular orientation of the pull towers with respect to the track members, and two pairs of vertical bolster cylinders powerably positionable in both horizontal directions within the track members each having clamp elements provided on the upper ends thereof for anchoring the vehicle to the apparatus. Horizontal displacements of the bolster cylinder pairs are effected remotely by actuating electric motors while vertical motion of the clamp elments are accomplished by fluid lifters. Proximity sensors on each clamp element automatically signal the limits of vertical motion when a body portion on the underside of the vehicle is within grasp.
