  • Patent number: 10351348
    Abstract: A lifting device includes a body or frame, a track, a lifting mechanism having a trolley moveable relative to the track for lifting an object, a main set of wheels coupled to a base portion of the body/frame, a maneuvering set of wheels coupled to the base portion between at least a portion of the main set of wheels and the trolley and vertically offset from the main set of wheels, and at least one arm extending outwardly from the base portion. The vertical offset between the main set and the maneuvering set of wheels forms a two stage lever which improves the mechanical advantage of the lifting device, thereby decreasing the amount of force needed to recline the object being lifted by the lifting device.

  • Patent number: 6913431
    Abstract: An apparatus for unloading packages, parcels, postal items, baggage, etc., from a container having an open side. The apparatus has a sliding wall that is disposed over the open side of the container when the container is receiving within the apparatus. The apparatus, along with the container, is tilted such that the open side of the container is generally directed downward. From this tilted orientation, the sliding wall of the apparatus is withdrawn, incrementally exposing the open side of the container, permitting the controlled egress of the packages, etc., from the container.
