Abstract
A two-position lift bridge is used with a jack-stand power unit including a forward end, a rearward end, a pair of upward side flanges, with the rearward end having a hydraulic cylinder. A rear cover plate extends horizontally from the side flanges and over the cylinder, and has vertical apertures for positioning the lift bridge, and has a threaded vertical aperture for securing the lift bridge. The frame has a pair of parallel lift arms having forward end that are extendable by the cylinder. Each forward end has a leveling pad pivotally attached having an outwardly extended flange, and one having a vertical aperture and a threaded aperture. The lift bridge includes a rectangular plate one side having downward extending corner flanges with horizontal openings for engaging one of the outwardly extended flanges of the leveling pad. The other side of the plate has a pin extending downward for engaging the aperture in the other leveling pad, and includes a vertical aperture that is aligned with the threaded aperture of the leveling pad for receiving a fastener. The lift bridge can be stored on the cover plate and secured with the fastener. The lift bridge can be positioned on the forward ends of the lift arm by placing the corner flanges on the outward flange of one leveling pad, then positioning the downward pin into the aperture in the other leveling pad, and secured with the fastener.
