ABSTRACT:
Mobile shelving apparatus comprises rails that are leveled by stacks of interlocking shims. The shims are placed under and interlock with rail support brackets at the joints in the rails. Rail spreaders used to align the rails are also leveled with and interlock with the shims. The mobile shelving apparatus includes a carriage platform supported on the rails by wheel assemblies that are assembled to the platform without fasteners. Wheels are retained to bearings by swaging portions of the wheels onto the bearing outer races. The bearing inner races are retained on respective shafts by swaging rings onto the shafts. The wheel assembly shafts are secured to the platform by swaging the ends of the shafts to the platform. The invention further comprises an upright anchor clip for joining the platform to the carriage framework that stores selected items.
