ABSTRACT:
An automatic-slide-forward-lift bridge for use with a jack stand power unit. The power unit has a rectangular frame base and a pair of parallel lift arms with forward ends for raising and lowering the jack stand. The lift arms have leveling pads attached to the forward ends. Each leveling pad includes a rectangular plate oriented vertically having a rearward edge and an upper surface with a flange extending outward for use with the lift bridge, and for use with a compression spring mechanism for biasing the bridge toward the forward ends of the lift arms. The lift bridge comprises a rectangular plate having an upper surface, a bottom surface, a forward end and a pair of sides. Each side of the lift bridge has an inner channel for engaging the outward flange of the respective leveling pad, and each side further has a finger extending rearward from the rectangular plate with a flange extended downward for abutting the rearward edge of the leveling pad.
