A steering jack (11), actuated by a pressurised fluid controls the pivoting of the cylinder supports (4 and 5) of the grader roller (road roller). This jack is connected to the chassis by means of an articulation (15) allowing the angular and lateral movements of the jack with respect to the chassis. By virtue of this arrangement, the cylinders lie perfectly inscribed inside the trajectory when the roller changes direction. <IMAGE> |
