Apparatus is provided for determining the relationship between a vehicle\s thrust line and the vehicle\s body center line. A movable light source is located externally of and independent of the vehicle and serves to establish a pair of reference light beams falling in parallel planes and which are spaced apart sufficient to permit a vehicle to be positioned longitudinally therebetween. The vehicle\s thrust direction is determined by mounting sensors on the nonsteerable wheels so as to extend transversely away from the vehicle\s body to intercept the ligh...
Apparatus for use in determining the relationship between a vehicle\s thrust line and its body center line wherein said vehicle has at least one steerable wheel spaced longitudinally from a pair of laterally spaced nonsteerable wheels and comprising: movable light source means located independently of and remote from said vehicle for establishing a pair of parallel reference light beams extending from a position located forwardly of said steerable wheel and directed rearwardly alongside and spaced outwardly from said nonsteerable wheels and wherein said ...
