A dolly for supporting a tank standing on end is provided with a T-shaped plastic base formed by a crossarm and a leg that are joined by an adjustable interlocking connection. Both ends of the crossarm and the end of the leg remote from the crossarm are provided with arcuate grooves that receive the bead surrounding the bottom of the tank. The heads of fastening screws extend over the grooves to retain the bead therein. A metal axle rod extends through a longitudinal passage in the crossarm. This passage has an open top in the region between the grooves in the crossarm so that a tank on the base engages the rod to be supported directly thereby.
