A high deck multi-level ambulance cart. An upper frame forming a bed is supported above a lower frame, having wheels, by forward and rearward legs. The upper frame supports a longitudinal beam. The upper ends of the legs are slidably mounted on the beam and have multiple positions along the beam secured by releasable stops. By sliding the upper ends of the legs to selected positions, the upper frame can assume the following positions: (a) a transport position in which the frame is horizontal and legs are generally vertical; (b) a loading position in which the frame is shifted to an upwardly-inclined position by sliding the forward legs in a forward directon; (c) an intermediate position in which the upper frame is lowered to a horizontal position, below its transport position, by sliding the upper ends of the legs in a rearward direction while swinging the lower ends of the legs forward; (d) an in-car position with the legs swung rearwardly to lie against the upper frame.
