摘要：
A patient transport apparatus for transporting a patient over a surface. The patient transport apparatus has support wheels coupled to a base and swivelable about swivel axes. An auxiliary wheel assembly is coupled to the base and includes an auxiliary wheel configured to move between a plurality of wheel positions, and an actuator operably coupled to the auxiliary wheel to move the auxiliary wheel between the plurality of wheel positions. A sensing system with a sensor is provided to detect a motion condition of the patient transport apparatus. A controller is coupled to the sensing system and to the actuator, and is configured to drive the actuator to move the auxiliary wheel between the plurality of wheel positions based on the motion condition of the patient transport apparatus.
