Abstract
Caster wheel assemblies that may be snap-fitted onto a cylindrical tank or drum are shown and described. Also dolly-wheel assemblies that include an axle supported by two wheels are also disclosed which may be snap-fitted onto a cylindrical tank or drum. The caster wheel assemblies and dolly wheel assemblies disclosed herein may be easily mounted onto a tank or drum without the need for a separate supporting platform. A flexible nature of the caster wheel assemblies and wheel-dolly assemblies enables them to be snap-fitted onto tanks of varying diameters.
