Claim 46:
47. The improved auto-chocking enabled cargo dolly of claim 30 further comprising a cargo weight sensor disposed on the dolly frame to detect a weight level of cargo supported on the dolly frame, the weight sensor being operatively coupled to the electronic control module to provide weight sensor data indicating the weight level of the cargo supported on the dolly frame; and
wherein the electronic control module being further operative to
receive the weight sensor data from the weight sensor over a period of time,
determine when a change in weight of the cargo supported on the dolly frame exceeds a threshold cargo weight change based upon the weight sensor data over the period of time, and
responsively trigger the hub-based chocking actuator to cause the hub-based chocking assembly to hold the at least one of the wheels in place by engaging the braking hub extension to hold the braking hub extension in place when the change in weight of the cargo supported on the dolly frame exceeds the threshold cargo weight change.
