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.
