Non-ground engaging lifting apparatus for detachable gooseneck trailers

摘要

The present invention is comprised of cylinders with extensible pistons which extend between first points located on a trailer and second points located on a gooseneck which interconnects the trailer to a tractor. The gooseneck and the trailer are rotatably coupled to one another at a common pivot point. The first points and second points are arranged relative to one another such that as the piston in the cylinder is extended or retracted, the gooseneck and trailer are respectively raised or lowered relative to the ground. The gooseneck is arranged so that it substantially encloses the cylinders throughout their entire range of travel thereby protecting them from damage. In addition, a locking apparatus permits locking the pistons to both the first and second points to present rotation of the gooseneck relative to the trailer. Thus the gooseneck and trailer can be removed from the tractor as a single unit.
