ABSTRACT:
A lift table mechanism has a thread screw secured upright within a support tube; a driven nut threadedly mounted to the screw which is raised and lowered by rotating around the thread screw; a carriage frame attached to the nut and supporting a table surface; a drive engaging a main driver gear connected to the drive; and an idler gear coupled to the main driver gear and in turn engaging the nut. Alternatively, a cross shaft driver is rotatably coupled between the main driver gear and the idler gear; a cross shaft connects cross shaft drivers of multiple table lift mechanisms wherein the cross shaft drivers rotate concurrently.
