Patient Transport Apparatus Having Track Assembly Brace

A patient transport apparatus for transporting a patient along stairs. The patient transport apparatus includes a support structure including a rear support assembly and a track assembly extending from the support structure. The track assembly includes a rail extending between a first and second rail ends. The track assembly further includes a roller adjacent to the first rail end, a motor supporting a pulley adjacent to the second rail end, and a belt supported in engagement with the roller and the pulley. The track assembly further includes a lateral brace operatively attached to the rail and defining a brace configured to abut at least a portion of the belt to retain the belt in engagement with the roller for limiting lateral movement of the belt relative to the rail occurring in response to force acting on the belt between stairs and the roller during operation of the motor.
