ABSTRACT:
A mobile base assembly for movably supporting machinery comprises stamped corner members, extension members, support wheel attachments, caster wheel assemblies, and at least two stops for supporting the machinery in a stationary position. The extension members and the corner members each have a plurality of holes. The holes in the extension members can be aligned with the holes in the corner member for receipt of bolts to fasten the extension member to the corner member. Further, each caster wheel assembly has a lifting mechanism that allows the mobile base assembly to be raised and lowered. The mobile base assembly is mobile in the raised position and stationary in the lowered position. In an alternative embodiment the support wheel attachments and caster wheel assemblies are attached directly to the machinery.
