Multiple level roll-in cot

A multiple level elevating cot adapted to be rolled into emergency vehicles, the cot having a wheeled undercarriage supporting a cot frame having a leading end and a trailing end, and adapted to selectively secure the cot frame in a plurality of elevational positions. The cot frame includes a pair of side extension arms provided between the leading end and the trailing end, each of the side extension arms being adapted to slidably extend outwardly from a stowed position adjacent the cot frame to an extended position substantially perpendicular to the cot frame. The cot further includes a drop frame that may be lengthened and sidearm supports positionable in vertically-up, vertically-down, substantially horizontal, and a folded position relative to the cot frame. The cot frame may form a part of an integral stretcher or may serve as a carrier to which a separable top structure mounts.
