Abstract

A universal measuring bridge for determining the amount of misalignment of the datum points on a damaged vehicle, the bridge including a main beam formed from two extruded box beams, each box beam including a reference surface and an upper and lower track, the box beams being connected with the reference surfaces in a precise parallel spaced relation and the tracks also in a precise parallel spaced relation to each other and to the corresponding tracks on the other side, a slide arm having an upper and lower track and an upper and lower rail on each side and a fixed guide and a movable guide on the bottom for aligning the slide arm on the main beam and a cross slide mounted on each end of the slide arm, the cross slide including a pair of rollers positioned to ride on the lower track on each side of the slide arm and a compensating roller positioned to ride on the upper track, the rollers on the lower track being adjustable with respect to the lower track and movable into engagement with the inside of the rails. An overhead bridge assembly for measuring upper body datum points can be mounted on each end of the main beam, each assembly includes both adjustable cross bars and longitudinally extending bars for supporting both vertical and horizontal pointers.
