An assembly for actuating a work support surface in perpendicularly extending fashion relative to a load bearing surface. A drive motor includes a first end fixed to a location along the load bearing surface, a second extending and linearly translatable end securing to an underside of the work support surface. A pair of support channels are arranged at equidistant and opposite extending sides relative to the drive motor. Each of the support channels are secured in parallel spaced and extending fashion along the load bearing surface relative to a direction of linear translation of the motor. A pair of support brackets each include upper edges securing to underside locations of the work support surface, corresponding side edges being secured in freely slidable fashion through an open extending edge defined within a face of each of the support channels. A switch secured to a location of the work support surface is actuated to operate the drive motor to raise and lower the work support surface.
