Abstract
A road finisher comprising a chassis is described, the chassis being movable on a travelling gear and carrying a front stock hopper, a primary drive unit an incorporated secondary drive units. The road finisher is provided with a paving screed which is dragged at the rear and which is articulated on the chassis via laterial outriggers, as well as with a lifting device which is provided between the chassis and the outrigger and by means of which the paving screed can be moved to a transport position raised from the ground. The troublesome influence of the paving screed when the road finisher travels for the purpose of transportation is reduced or eliminated to a large extent in the case of such a road finisher. For this purpose, the road finisher is provided with a dynamic absorber system comprising an actuable support for the paving screed occupying the transport position, the support being elastic relative to the chassis and effective in the lowering direction, as well as an absorber mass defined by the paving screed.
