Abstract
A method and apparatus to regulate the use and removal of freight. The apparatus includes a sensing element, a stoppage element, and at least one actuator. The sensing element is operable to determine the presence of freight. Stoppage element can alternate between a first condition configured to impede freight removal and a second condition configured to permit freight removal. The presence of freight maintains stoppage element in the first condition absent engagement of the at least one actuator and engagement of the at least one actuator switches stoppage element to the second condition when freight is present.
