Abstract: A security vehicle adapted to prevent unauthorized entry thereinto comprising a base with an electrically conductive frame, an insulated platform on the frame and steerable propelling means for moving the base; a cage defining a security chamber over the platform carried by the base frame with an open electrically conductive framework and see-through security panels closing the openings in the framework. A selectively closable access opening is provided in the front end of the cage and a high voltage, low current charging unit imposes a high voltage, low current charge on the base frame and cage framework.
