In accordance with the present invention, a patient support apparatus includes a frame, a patient support deck coupled to the frame, a tray positioned below the patient support deck for supporting an x-ray cassette, and a lifting apparatus for lifting the tray toward the patient support deck. The lifting apparatus includes a shiftable member supported for translation relative to the frame in a longitudinal direction. A pair of links are coupled to the shiftable member. A first link of the pair of links has a first end pivotally coupled to the tray and a second end pivotally coupled to the shiftable member. A second link of the pair of links has a first end pivotally coupled to the frame and a second end pivotally coupled to the shiftable member. A handle is coupled to the frame for translating the shiftable member in the longitudinal direction to spread apart the links and lift the tray.
