  • Patent number: 8500102
    Abstract: A retractable jack foot for a trailer hitch jack is disclosed, for rapidly raising and lowering the tongue of a trailer. The retractable jack foot solves multiple prior art problems discussed above in the “Description of Related Art,” such as: trailer hitch jacks not being long enough to reach the ground and still lift the trailer to a sufficient height (small distance travel); the laborious, time-consuming practice of cranking a trailer hitch jack all the way to the ground before finally causing lift in the trailer. In both cases, blocks of wood or other spacers are sometimes used to reduce the travel of the jack. The retractable jack foot of the present disclosure, solves those problems, by providing a “built in” block, or foot, pivotally attached to the bottom of the trailer hitch jack. The jack foot can be rotated into and out of position as desired, to quickly lengthen or shorten the jack.

  • Publication number: 20100155682
    Abstract: An improved jacking system for a liftboat with a high speed manifold system with high speed motors and high speed planetary gear drives, a heavy lift manifold system with heavy lift motors and heavy lift planetary gear drives, and bypass valves for diverting hydraulic pressure between the high speed manifold system and the heavy lift manifold system. The improved jacking system makes the boat easier to position precisely and expands the weather and sea condition envelope the liftboat can operate in by reducing its exposure to multiple impact stresses while jacking up in rough sea conditions. The improved jacking system also serves as a safety device which can quickly “tag” the bottom to stop and stabilize the liftboat's motion in a close situation.
