摘要：
A powered ambulance cot and methods of raising and lowering the cot as well as loading and unloading the cot are disclosed. The cot includes a support frame and legs, each leg having a wheel. An actuator of an actuation system interconnects the frame and legs, and is configured to effect changes in elevation of the frame relative to the wheel of each of the legs. A control system controls activation of the actuation system, and detects both the actuator at a first location relative to the frame, where the first location is remote from a second location and which situates an end of the actuator that is remote from each wheel closer to the frame, and a presence of a signal requesting a change in elevation of said support frame to thereby cause the legs to move relative to the support frame.
