Abstract
A vibratory compacting roller adapted to be coupled to a prime mover and equipped with hydrostatic drive and vibrator, both drivingly connected to a hydraulic power generator located on said prime mover, is provided with recessed tamping elements distributed in parallel adjacent rows around the periphery of the roller cylinder face with a peripheral offset between adjacent rows. The tamping elements are of trapezoidal design with a semi-circular recess extending centrally from the base to the short side, said recess rendering a vibrational compacting roller with tamping elements equal in weight to a plain vibratory compacting roller of the same over-all diameter.
Claims13
A vibratory compacting roller apparatus, comprising:
- a frame;
- a roller drum, rotatingly received in said frame;
- drive means, connected to said roller drum, for driving said roller drum;
- vibrating means, connected to said roller drum, for vibrating said roller drum;
- a plurality of substantially trapezoidal shape tamping elements disposed about an outer cylindrical surface of said roller drum, each of said tamping elements having disposed therein a recess open toward said outer cylindrical surface, said roller drum and tamping elements being so arranged and constructed that a total weight of said roller drum and said tamping elements is substantially equal to a weight of a plain roller drum of the same overall diameter;
- and
- wherein each of said substantially trapezoidal shape tamping elements is further characterized as including an elongated ground engaging surface having a length greater than a projecting height of said tamping element.
