A collapsible hydraulically operated ambulance cot (2) having a support frame,a wheeled base, a support mechanism (16) disposed therebetween, and a liftsystem (10) for hydraulically moving the upper (12) frame relative to thelower frame (14) is disclosed. The lift system (10) permits a single attendantto raise the cot (2) from a lowered position to a raised position, and aninfinite number of positions therebetween, and to raise the wheeled baserelative to the support frame to situate the cot onto an elevated surface suchas the transport deck of an ambulance. A manual override is also provided toconserve battery (30) power and as a back-up in no-power situations. It is tobe appreciated that the above described manual override mode may be used whenraising or lowering the cot (2) without power assist, dropping theundercarriage (11) when unloading from a vehicle, and lifting theundercarriage (11) when loading into a vehicle.
