Abstract
Apparatus for loading and unloading a vehicle comprising a supporting frame having a pair of parallel spaced horizontally extending elongated tracks supported near the ends thereof by upstanding legs and elongated cross members operatively secured to said tracks adjacent the upper ends of said legs thereby defining a loading space within said frame. A hoist carrier is mounted on the tracks for movement longitudinally thereof. The carrier lies substantially within the plane of the tracks near the top of the space. A hoist boom is pivotally mounted on the carrier adjacent one of the tracks, the boom extending horizontally beneath the carrier and being swingable across the space between the tracks. The boom is also movable with the carrier longitudinally of the frame.

Apparatus for loading and unloading a vehicle comprising a supporting frame having a pair of parallel spaced horizontally extending elongated tracks supported near the ends thereof by upstanding legs and elongated cross members operatively secured to said tracks adjacent the upper ends of said legs thereby defining a loading space within said frame;
- a hoist carrier frame mounted on said tracks for movement longitudinally thereof, said carrier frame lying substantially within the plane of said tracks to be disposed at the top portion of said space;
- a hoist boom pivotally connected to said carrier frame adjacent one of said tracks, said boom extending horizontally beneath said carrier frame and swingable across said space between said tracks, said carrier frame including elongated elements secured together in the shape of a sector of a circle, the arcuate portion of said carrier frame serving as a trackway, said pivotal connection being adjacent to the apex formed by said two straight sides, said boom having first means movably engaged with said trackway to support swinging movement of said boom, said carrier frame having second means movably engaged with the other of said tracks, one straight side of said sector being disposed parallel to one of said tracks and having third means movably engaged with said one track at longitudinally spaced points thereon, the other straight side of said sector extending between said tracks.
