ABSTRACT:
A device is disclosed for changing the position of a load-carrying component of a transport unit relative to a support surface on which the transport unit is movable, and in which the load-carrying component such as a chassis frame, is carried by at least one support leg which is provided with at least one contact member for the support surface which may be a wheel, caterpillar chains or a pontoon, or with at least one coupling device. The support leg is mounted on the load-carrying component through an articulation designed and arranged to allow swinging movement of the support leg relative to the load-carrying component. The support leg is connected to the load-carrying component through a power actuator unit which is designed and arranged to swing the support leg so as to cause the position of the load-carrying component to change relative to the support surface to an extent corresponding to the degree of angular motion of the support leg. One power actuator unit is designed and arranged to retain the support leg in its set position relative to the load-carrying component, and the other power actuator unit is designed and arranged to become loaded by the load-carrying component together with any load carried by said last-mentioned component.
