ABSTRACT:
A vehicle with a vertically adjustable auxiliary axle and having its center of gravity located behind the auxiliary axle so that when said axle is moved down to a testing position where its wheels engage the ground, the front wheels of the vehicle are raised off the ground and the entire vehicle weight is supported by the rear wheels and the auxiliary wheels. When the auxiliary axle is in a testing position, the distance between the outer edges of the contact surfaces of the auxiliary and rear wheels is on the order of but not greater than 10 feet. The vehicle may be rolled over a scale platform while in the testing position so that a known weight is applied in an infinite number of 10 foot sections. The scale may be calibrated to accurately reflect the known weight under all different applications of that weight.
