A stretcher for transporting a patient along a floor includes an elongated frame, a patient-support deck carried by the frame, and an elongated shaft having a longitudinally-extending axis of rotation. The shaft is coupled to the frame for rotation about the axis of rotation between a first orientation and a second orientation. The stretcher also includes a wheel supported relative to the frame and movable relative to the frame in response to rotation of the shaft. The wheel is in a first position engaging the floor when the shaft is in the first orientation and the wheel is in a second position spaced apart from the floor when the shaft is in the second orientation.
