Abstract
The present invention is directed toward an apparatus for quickly configuring a jack to raise a load from its rest position. In particular, the present invention provides a jacking mechanism that telescopes from a locked, elevated position to a locked, lowered position in order to situate the jacking mechanism for raising a load. Correspondingly, the present invention provides a jacking mechanism that telescopes from its locked, lowered position to its locked, elevated position for stowing the mechanism between uses.
