  • Patent number: 5088855
    Abstract: A device for compacting surfaces includes a frame and wheels rotatably mounted to the frame. At least one compacting cylinder structure is rotatably mounted to the frame and has an operative position between at least two wheels and the surface to compacted. Structure for driving at least two wheels is provided. The frame is provided in the form of a vehicle whereby the weight of the vehicle and the weight of the driver contribute to compacting the surface. The compacting cylinder comprises disk structures mounted about a central shaft. The disks are secured to an inside surface of a cylindrical sleeve of the compacting cylinder which serves to reduce the inside diameter to a size compatible with a small axle diameter and to provide a cavity to support a bearing assembly. A means for engaging and disengaging the driven wheels and the compacting cylinder is provided.
