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. A cutting wheel is alternatively mounted to the central hub for cutting pavement preparatory to excavation.
In a wheel compaction unit of the type generally comprising a plurality of compacting wheels mounted to an axle and frame, the compacting wheels including spaced-apart, radially outwardly protruding compacting feet each having a compacting sole surface, the improvement comprising a wear collar removably mounted closely surrounding each compaction foot, the wear collar defining an opening therethrough sized and shaped to fit over and surround the compacting foot, leaving the compacting sole of the compacting foot exposed while protecting the portions of the compacting foot adjacent the compacting sole surface, whereby the wear collar sustains substantially all of the abrasion, impact, damage and wear inherent in the compaction operation and is replaceable.
In a wheel compaction unit of the type generally comprising a plurality of compacting wheels mounted to an axle and frame, the improvement comprising a compaction wheel integrally fabricated of plate steel and having a periphery configuration characterized by a plurality of spaced-apart compaction feet each deployed on the distal end of a presentation support extending from a circular rim portion of the wheel, each presentation support having angled leading/trailing presentation surfaces and the compaction foot having a height approximately on half the height of the presentation support, and the compaction foot having a rectangular compaction sole surface.
