Claim 29:
30. An improved auto-chocking enabled cargo dolly that is towable by ground support equipment, the cargo dolly comprising:
a dolly frame,
an axle disposed on the dolly frame;
a set of wheels attached to the axle, wherein the set of wheels supports at least a portion of the dolly frame, wherein each of the wheels contacts ground below the dolly frame and rotates to allow movement of the dolly frame;
an electronic control module disposed on the dolly frame;
a connection sensor disposed on the dolly frame and operatively coupled to the electronic control module, the connection sensor providing connection sensor data to the electronic control module indicating when the dolly frame is connected to the ground support equipment;
a hub-based chocking actuator disposed on the dolly frame and operatively coupled to the electronic control module, the hub-based chocking actuator being responsive to a control input generated by the electronic control module based on the connection sensor data; and
a hub-based chocking assembly comprising
a braking hub extension removably attached directly to at least one of the wheels, and
a friction bracket having a first end responsively coupled to the hub-based chocking actuator and a second end engaging the braking hub extension to hold the braking hub extension in place when the hub-based chocking actuator is actuated by the control signal.
