Patient transport apparatus with electro-mechanical braking system

Abstract:

A patient transport apparatus comprises a base, a patient support deck, a wheel assembly, and a braking system. The wheel assembly includes a wheel and a braking mechanism. The braking system includes a linkage assembly, a manual actuator, and an electrical braking assembly. The linkage assembly is arranged to place the braking mechanism in a braked state and a released state. The manual actuator moves the linkage assembly manually to place the braking mechanism in the braked state and the released state. The electrical braking assembly includes a driving assembly that moves to a first position and to a second positing that causes the linkage assembly to place the braking mechanism in the braked state and the released state, and to a home position that allows the linkage assembly to move relative to the driving assembly to enable the braking mechanism to be manually actuated with the manual actuator.
