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.

1. An apparatus for supporting one wheel of a heavy, low-ground-clearance, vehicle during servicing, wherein:the apparatus is made of pieces of sheet metal, including a platform, including spaced opposed front and rear end panels, and including spaced opposed left and right side panels; the panels are welded together, in such manner that the apparatus has the general configuration of an upturned hollow box, with the platform on top; a wheel-receiving depression is formed in the platform; the apparatus has a bottom rim, which is adapted for resting on the ground, and the bottom rim is so arranged as to spread the load of the wheel onto a comparatively large area of the ground; at least some of the panels slope inwards, whereby either the end panels or the side panels are further apart at the bottom than at the top; the apparatus is wide open at the bottom; and the apparatus is capable of being arranged with other, similar, apparatus, one above and partially inside another, in a stack.
