ABSTRACT:
Apparatus for aligning the axle of a vehicle such as a truck, bus, etc., comprises a carriage adapted to be rolled into position adjacent the axle, a beam mounted on the carriage to pivot about a horizontal axis orthogonal to the axle, and means for projecting a laser ray coaxial with the pivot axis of the beam and onto a target positioned forwardly of the axle at a predetermined location with respect to the frame of the vehicle. The underside of the axle is engaged by a pair of forks adjustably carried by the beam to position the beam parallel to the axle. A centering mechanism is provided to center the laser with respect to the axle by causing the beam pivot axis to move laterally into a central position between the wheels of the vehicle. Preferably, the laser also projects a ray rearwardly through a central bore in the beam pivot pin to facilitate alignment of the laser with the pivot axis of the beam.
