ABSTRACT:
A wheel for a powered vehicle operating along a hard brittle surface is equipped with cleats 21 having non-metallic wear tips 31 mounted upon a metallic base 36 welded to the wheel circumference 10. The material forming the wear tips 31 has density and hardness insufficient to chip or erode the brittle work surface but of sufficient toughness for demolition of solid wastes. An elongate bracket in a medial portion 26 of the wear tip and base have complimentary portions for attachment of tip to base in a twist resisting connection. An adhesive bond unites the tip and base in one embodiment, FIGS. 4-7, and mechanical couplings unite the parts in others, FIGS. 7-13. Certain embodiments, FIGS. 8-13, have provisions for readily releasable locking of the parts for field replacement of worn cleats.
