  • Patent number: 8215867
    Abstract: A compacting device (40) for attachment to an earthmoving machine (2) to compact a substrate is described. The compacting device (40) includes a plurality of wheel assemblies (41, 42, 43) mounted for rotation in bearings (46). A support is also provided, having a base part (48) that is adapted to be mounted to the earthmoving machine (2). One or more bearing support members (47) extend from the base part (48) and between the wheel assemblies (41, 42, 43) to support the bearings (46). Each wheel assembly (41, 42, 43) includes a set of ground-contacting feet (44) secured to and peripherally spaced apart around a rim portion of the wheel assembly (41, 42, 43). In this arrangement, when the device (40) is rolled over the substrate a first foot of said set of ground engaging feet (44) contacts the substrate between axial width limits that differ from axial width limits of a second foot of said set of ground engaging feet (44).
