<p>The soil compaction apparatus (1) comprises a compaction plate (2) and at least an excentric rotatingly driven mass for creating a vibration. The plate (2) is provided with a shaft (5), arranged perpendicularly to the plate, and on which there is rotatingly mounted the excentric weight (10), at a predetermined distance from the plate (2). The excentric mass (10) may thus move in a plane parallel to the plate (2). By displacing the excentric mass (10) along the shaft (5), it is possible to decrease or increase the excentric effect, that is to say the lever effect on the compaction plate (2).</p> |
