Abstract
The frame of the chassis includes pairs of beams projectable forwardly and rearwardly, respectively from a center frame section on which a load-carrying body is mounted. The forward beam pair and the rear beam pair are projected from the center section corresponding distances by hydraulic jacks connected respectively between such beam pairs and the central section. The jacks are connected to transfer fluid between them, and fluid under pressure is supplied to the jacks to extend one jack and to contract the other jack simultaneously.
