Abstract: End and side panels, welded together to form a frusto-pyramid, are surmounted by a dished wheel-receiving platform, for supporting a truck etc wheel. The units are wide open underneath, for stacking. Hand holes in the end panels allow the units to be manhandled and stacked. A cross-brace under the platform strengthens the structure, and holds the stacked units apart.
