An apparatus for supporting a stretcher comprising: (a) a pair of horizontal beams (109, 110), each horizontal beam comprising: (i) first and second submembers (111, 112, 98, 99), each submember having an inboard end and outboard end; (ii) a pivoting hinge connecting the inboard ends of the submembers (111, 112, 98, 99), said pivoting hinge allowing the first and second submembers to move between a first unfolded position in which the submembers align substantially straight and parallel, and a second folded position in which the submembers lie substantially parallel to each other and define an internal space between the submembers; (b) one or more yokes (48, 49, 50, 51) connected to said horizontal beam (109, 110), said yokes adapted to receive a stretcher; (c) said yokes (48, 49, 50, 51) having an independently adjustable height; (d) a plurality of support members, in outwardly canted positions, attached to the horizontal beams (109, 110); (e) a pair of folding, connected cross-bars (3, 4) connecting a first support member (32a, 32c) to a second support member (32b, 32d) thereby maintaining the horizontal beams (109, 110) substantially in parallel when the apparatus is in the first unfolded position; and (f) each of said cross-bars (3, 4) having a hinge point to allow inward motion of the opposing pairs of support members to collapse the cross-bars (3, 4) until the cross-bars lie substantially parallel with each other and with the support members.
