摘要：A vibratory compacting roller adapted to be coupled to a prime mover andequipped with hydrostatic driving and vibration exciting means, both drivingly connectedto a hydraulic power generator located on said prime mover, is provided with recessedtamping elements distributed in parallel adjacent rows around the periphery of the rollercylinder face with a peripheral offset between adjacent rows. The tamping elements areof trapezoidal design with a semi-circular recess extending centrally from the base to theshort side, said recess rendering a vibrational compacting roller with tamping elementsequal in weight to a plain vibratory compacting roller of the same over-all diameter.
