A lift table includes a support table assembly mounted on a scissor arm mechanism. The support table assembly is raised and lowered automatically upon the imposition or removal of loads so that the height of the plane on which articles are being handled remains generally constant. Raising and lowering is effected via a lift spring assembly that acts without the assistance of any pneumatic or hydraulic actuators. The scissor arm mechanism of the lift table has angled arms and low-friction rollers to facilitate raising and lowering of the support table assembly and optimizing operation of the lift spring assembly. The resulting mechanically operated lift table is simple, reliable, and can be easily transported from location to location.
