A large capacity mobile storage system having a plurality of storage units and a plurality of interconnected support assemblies for rolling movement. Each of the support assemblies includes a frame and a pair of spherical shaped hardened steel support wheels. Only one of the support assemblies includes a pair of guide rollers disposed perpendicular to its associated support wheels in order to maintain rolling movement of the storage system along a linear path. The support wheels of the other support assemblies are allowed to move independently from one another in order to prevent the scrubbing action of the supporting apparatus. The supporting assemblies also include a drive track and a sprocket disposed at one end of the storage unit with a drive mechanism. This feature helps to keep the floor area between the flat tracks uncluttered. The apparatus compensates for a significant degree of unlevelness and undulation of the flat tracks caused by an unlevel floor upon which the flat tracks are mounted.

[ What is claimed is:] [1.] A large capacity movable storage supporting apparatus for movably supporting a storage system, the storage system including at least one storage unit, the storage supporting apparatus comprising:a plurality of generally rectangular flat tracks secured to a floor generally parallel to one another;a plurality of corresponding support assemblies for directly supporting said storage system at spaced apart points along said storage system;each of said support assemblies including a pair of rotationally supported support wheels for supporting said storage system for rolling movement in accordance with one of said flat tracks, each of said support wheels having a spherical surface for engaging its associated flat track;a pair of rotationally supported guide rollers in association with only one of said support assemblies for maintaining rolling movement of said support wheels in a generally linear path on said flat track;an elongated drive track fixedly disposed to said floor adjacent to the flat track secured farthest from a user engageable drive mechanism;a drive shaft operably interconnected with all of said support assemblies;a drive element fixedly coupled to said drive shaft and engaged with said drive track; andsaid user engageable drive mechanism operably associated with said drive shaft to enable rotation of said drive shaft, to thereby cause said drive element to drive said support assemblies simultaneously along said flat tracks with low rolling resistance, wherein said support assemblies which do not incorporate said guide rollers move independently of each other in a non-linear path.
