  • Patent number: 4950102
    Abstract: A wheel compaction unit for use on the articulated arm of heavy excavation equipment comprises a frame mounted to the equipment arm, the frame including support arms mounting a hub and axle assembly including three independently rotatable bearing mounted hubs. At least one compaction wheel is mounted to each hub, and auxiliary compaction wheels including angled spokes and an offset periphery are provided for mounting to the outside hubs to increase the working width of the wheel compaction unit. The hubs and axle assembly is sealed with ground metal seals and end plates. The periphery of the compaction wheels include spaced-apart presentation supports having angled leading/trailing edges, the presentation supports each supporting a compaction foot integral with the wheel. A removable wear collar closely surrounds the compaction foot and receives the primary impact and abrasion during use of the compaction unit, the wear collars being readily replaceable.
