Patent ID: 7780394

Claim:
A synchronized rotative lift apparatus for receiving a vehicle hitch comprising: a) a primary worm gear powering system comprising: a pair of worm gears connected by a worm screw shaft, first and second pillow block bearings, each of said first and second pillow block bearings being joined to a respective one of said worm gears, means for rotating said worm screw shaft; b) a first arm bar lift having a first end section projecting perpendicularly from said first pillow block bearing, a second arm bar lift having a first end section projecting perpendicularly from said second pillow block bearing, each arm bar lift having an angular midsection extending from its respective first end section at an obtuse angle, each arm bar lift having a second end section extending at an obtuse angle from its respective angular midsection parallel to its respective first end section; c) a lift platform for loading and unloading cargo for transport; d) a pair of pillow block bearings disposed on the underside of said lift platform, wherein each of said second end sections of said arm bar lifts extends into a respective one of said pair of pillow block bearings, each of said second end sections being rotatively disposed with respect to its respective pillow block bearing; and e) a receiver to provide means of attachment to the hitch of a vehicle; f) wherein said lift platform maintains a substantially horizontal orientation throughout a 360 degree swing due to the second end sections of said arm bar lifts remaining on the same horizontal plane as they rotate within said pillow block bearings of said lift platform; g) wherein said lift platform is moved between a lowered position and a raised position by rotating said worm screw shaft thereby synchronously rotating said worm gears and their respective arm bar lifts.
