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.
Claims21
A mobile base assembly for movably supporting machinery, comprising:
- support members having a support plate and side members, said side members having a plurality of holes;
- extension members each having a first end and a second end and a plurality of holes which can be aligned with the holes in said side member for receipt of fasteners to fasten said extension members to said support members;
- support wheels operatively connected to at least one of said support members for permitting movement of the machinery and for supporting the machinery;
- at least one pivotal wheel assembly operatively connected to at least one of said support members which supports the machinery, said pivotal wheel assembly having a lifting mechanism for raising and lowering the machinery;
- and
- at least one stop for supporting the mobile base in a desired location when said at least one pivotal wheel assembly lowers the mobile base.
A mobile base assembly for movably supporting a piece of machinery, comprising:
- at least two wheel assemblies adapted to be operatively connected to a first portion of the machinery, said wheel assembly including an attachment member having a support lip adapted to be positioned beneath the machinery, wherein said attachment member is adapted to connect to the machinery, and at least one wheel connected to said attachment member by an axle;
- and
- at least one caster wheel assembly connected to a pivotal plate;
- said pivotal plate being connected to a mounting bracket for pivotal movement with respect to said bracket and a lifting mechanism connected to said pivotal plate, said bracket adapted to be operatively connected to a second portion of the machinery, wherein said caster wheel assembly is adapted for raising and lowering the machinery.
A caster wheel assembly for movably supporting machinery, comprising:
- a mounting bracket;
- a pivot plate pivotally connected to said mounting bracket;
- a caster wheel mounted to said pivot plate;
- and
- a lifting mechanism connected to said mounting bracket and operatively engaging said pivot plate;
- said lifting mechanism has a cam surface and is adapted to pivot between first and second position, wherein said first position corresponds to said pivot plate pivoting downwardly with respect to said mounting bracket to raise the machinery so that the machinery can be rolled and said second position corresponds to said pivot plate pivoting upwardly with respect to the bracket to lower the machinery so that the machinery is stationary in position and cannot be rolled.
