ABSTRACT:
The present invention relates to a soil compactor equipped with at least one movable drum. To generate the desired compacting forces, the drum is equipped with two oppositely rotating exciter shafts which are matched to one another in their phase positions so that, if the exciter shafts are vertically superposed, their centrifugal forces act horizontally and in the same direction, thus causing a moment free horizontal force to be exerted on the drum axis, while, with the exciter shafts disposed in a juxtaposed arrangement, the centrifugal forces are amplified in the vertical direction and compensate one another in the horizontal direction.
