Abstract: An earthmoving scraping device has a bowl-shaped frame with walls and a frame floor that define an interior for transporting material and a walking beam system for the rear wheels thereof that includes a suspension arm pivotally connected between the back end of the frame and a beam, the beam having first and second axles on separate sides of the beam. Connected to the axles is a tire system that includes a cylindrical metal rim with an outer surface and a plurality of solid tire segments, each of the tire segments having at least one track that is connected to a mounting plate, the mounting plates being circumferentially positioned adjacent to the outer surface of the rim.
