ABSTRACT:
A stage or other structure having support legs includes rollers which are mounted so as to be supporting the stage in a first position and having the stage legs support the stage in a second position. A lift mechanism includes actuating pedals near the ground for raising and lowering the assembly. A linkage pivots the roller mounting member between a raised and lowered position relative to a cross member on the frame. A second pedal is selectively engageable by a single foot for retaining the roller assembly in either the raised or lowered positions.
