Japanese Patent JPS6333081
Kind Code:
B2
Abstract:
The apparatus comprises two runners which are situated in front of a crossbar and form the forward supports of a T-shaped beam. A central shank is pivotingly connected to a rocking-lever which rests on two other runners. Twin wheels of the rear axle of a load-bearing vehicle advance, while the apparatus continues to rest on its four runners, from a position in which the wheels are in line with the rear runner of the rocking-lever to a position in which they are in line with the front runner of the rocking-lever. Although both of these runners are successively situated in the zone where the road surface is deformed, their movements are complementary, so that the pivoting axis remains at the same level. The T-shaped beam thus forms a reliable reference for a horizontal plane relative to which measuring arms pivot, so that the movements of feelers aligned with the front runner of the rocking-lever can be recorded.
