ABSTRACT:
A weight vehicle apparatus useful for calibrating vehicle scales incorporates a unique pivoted suspension system which uniformly distributes the weight contained in the vehicle apparatus over the surface upon which it rests. The suspension system comprises three axle assemblies: a rearward axle having steerable wheels which is pivoted about the longitudinal axis of the vehicle, a forward axle position having individually driven wheels which are secured to a bogie-like subframe which is transversely pivoted relative to the vehicle and a third axle positioned between the front and rear axles and pivotally secured to the bogie-like subframe for motion about the longitudinal axis of the subframe as well as about the transverse axis of the vehicle apparatus.
