ABSTRACT:
A site preparation/concrete finishing apparatus for operation in an area having a base surface above which concrete reinforcing elements have been positioned prior to pouring of concrete within the area and for use in finishing concrete poured within the area. The site preparation/concrete finishing apparatus comprises a movable vehicle having at least one lift arm, a plurality of specially-tailored wheels for supporting the movable vehicle entirely within the area in continuous contact with the surface and for enabling continuous movement of the movable vehicle relative to the surface absent damage to the concrete reinforcing elements beneath the movable vehicle, and a concrete finishing device connected to the lift arm for fine grading and leveling of the area and for screeding and floating concrete poured within the area. Each wheel of the plurality of wheels includes a hub and a plurality of members extending radially therefrom. Each member of the plurality of members has a first end near the hub and a distal second end, and includes an arcuate surface proximate the second end. Each member also tapers over at least a portion of the distance between the first and second ends. The arcuate surface of each member aids in preventing the trapping of a concrete reinforcing member between the base surface and the site preparation/concrete finishing apparatus. The tapered portion of each member tends to direct a concrete reinforcing member contacted by the member slidably away from a longitudinal axis of the member.
