Date Jun. 28, 1990.Compaction plank for a road-finishing machine for incorporating and compacting freshly laid roadmaking material (3), preferably having a variable effective width. To this end, the compaction plank preferably comprises a main plank and laterally extendable adjusting planks. It also has a base plate (2, 18) for flattening the roadmaking material (3) associated with one or more bar-shaped, driven stampers (5, 6). Two stampers (5, 6) are provided, namely a front stamper (5) arranged in front of the base plate (2, 18) in the direction of travel (4) of the road-finishing machine and a rear stamper (6) arranged between the elements of the base plate (2, 18). The stampers (5, 6) are preferably interconnected by a two-armed lever (7), each stamper (5, 6) being connected with one of the two lever arms (7a, 7b), and the lever (7) can be driven so as to oscillate about its bearing point (8). |
