Systems and methods for improved automatic chocking of a cargo dolly

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;
• a tow bar flexibly attached to the dolly frame, the tow bar having a first attached end movably attached to the dolly frame and a second distal end having a ground support equipment connector disposed on the second distal end, the tow bar having a raised position where the second distal end is raised and not connected to the ground support equipment and a lowered position where the second distal end is lowered in a configuration to be attachable to the ground support equipment;
• a linkage in communication with the tow bar, wherein the linkage actuates from a first position when the tow bar is in the raised position to a second position when the tow bar is in the lowered position;
• 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 linkage and a second end engaging the braking hub extension to hold the braking hub extension in place when the linkage is actuated to the first position by the tow bar.
