摘要：
A tamping machine for compacting soil has a crank mechanism for producing a directed vibration. The crank mechanism is coupled to a spring assembly. The parts of the crank mechanism which move back and forth linearly are made from a material with a density less than that of steel. This construction prevents vibrations which are unpleasant for the person operating the working machine from occurring.
