ABSTRACT:
A vehicle levelling device includes a vehicle body with a rear section and a rear axle carried under the rear section of the vehicle body to provide support therefor. A support yoke is hingedly mounted to the vehicle body for pivotal movement about a transverse axis in a vertical plane. The support yoke holds the rear axle in a manner that the rear axle can rotate about a longitudinal axis. A hydraulic cylinder is attached to the vehicle body at a first end and to the support yoke at a second end so that it can be operated to lower or raise the rear section of the vehicle body with respect to the rear axle to thereby bring a tilted forklift into a horizontal position. Operation of the hydraulic cylinder is controlled by an electronic controller which in turn receives a tilt signal from a tilt sensor.
