Abstract
A patient transport apparatus operable by a user for transporting a patient along stairs. A seat section is coupled to a support structure. A track having a belt is attached to the support structure and is arranged for selective operation between: a retracted position, and a deployed position to engage stairs. A drive system with a motor is disposed in rotational communication with the belt to control movement along stairs in the deployed position. A user interface us arranged for engagement to selectively adjust operation of the drive system between: an active state for controlling movement of the belt with the motor, and an inactive state. A braking controller is configured to sense movement of the belt in the inactive state, and to control the motor to limit movement of the belt in the inactive state to effect corresponding limited movement of the patient transport apparatus along stairs.
