1. An emergency cot comprising:
a litter frame having a head-end and a foot-end;
a base; and
a lift assembly mounted to said base, said lift assembly including X-frame members coupled to said litter frame by a plurality of foot-end mounts and a plurality of head-end mounts, said plurality of head-end mounts to said litter frame being closer to said head-end than said foot-end of said litter frame, said plurality of foot-end mounts to said litter frame being closer to said foot-end than said head-end of said litter frame, said lift assembly operable to raise or lower said litter frame with respect to said base, wherein said litter frame can be raised between a fully raised position when said lift assembly is fully extended and a fully lowered position when said lift assembly is fully retracted, and wherein said lift assembly is configured to allow said litter frame to be tilted relative to said lift assembly when said lift assembly is fully extended and based on application of a downward force to the foot-end to cause longitudinal movement of a movable member of the plurality of foot-end mounts, wherein the litter frame is tiltable relative to said lift assembly so that said head-end of said litter frame and said plurality of head-end mounts can be raised beyond said fully raised position of said litter frame without decoupling said litter frame from said lift assembly.
