ABSTRACT:
In combination with a treadway upon which a vehicle, whose structure is to be realigned, is positioned, an improved alignment apparatus interconnecting the treadway and a selected portion of the vehicle structure. The alignment apparatus has a base assembly having a horizontal leg with a vertical member attached thereto, and a clamping assembly secured to the vertical member for attachment to the vehicle structure. The horizontal leg is adapted to rest on the treadway and is interconnected to a plurality of spaced openings in the treadway. The alignment apparatus may be rigidly secured to the treadway, or may slide across the treadway in response to a pulling force applied either to the vehicle or the alignment apparatus all while supporting the vehicle structure.
