Patient transport apparatus with electro-mechanical braking system

A patient transport apparatus comprising:

• a support structure including a base arranged for movement along a floor surface, and a patient support deck to support a patient;
• a movement mechanism coupled to the base and configured for selective operation between a first state to at least partially inhibit movement of the base along the floor surface in one or more degrees of freedom, and a second state to permit movement of the base along the floor surface in at least one degree of freedom;
• a manual operation assembly including a linkage assembly operatively attached to the movement mechanism and defining a positioning slot, and a foot pedal coupled to the linkage assembly and arranged for selective user engagement to move the linkage assembly manually to change operation of the movement mechanism between the first state and the second state;
• and
• an electric operation assembly including a driving assembly having a positioning member disposed in the positioning slot of the linkage assembly, and an electric motor configured to move the positioning member along the positioning slot and into torque transferring engagement with the linkage assembly to electrically change operation of the movement mechanism between the first state and the second state.
