ABSTRACT:
The present invention relates to a laser gauging apparatus for measuring a vehicle during the construction of and the repair of the vehicle. The apparatus includes a T-shaped rail arrangement. On one of the rails, a laser carriage is mounted which carries a laser along the rail. Laser measuring instruments are mounted on the other rail. The laser gauging apparatus projects a beam having a horizontally extending portion and a vertically extending portion. The horizontally extending portion defines a horizontal datum plane under the vehicle from which measurements can be taken to the vehicle to determine the correct position of datum points on the vehicle. In accordance with the present invention there is also provided a laser target which can be suspended from the datum vehicle point. The target when suspended and when intersecting the laser beam, indicates that the vehicle reference datum point is in proper position.
