Abstract:
An operable barrier system for vehicles includes a turntable for use with a trafficable surface and at least one impact element disposed on the turntable. A drive system is provided to rotate the turntable along the trafficable surface between a first position to prevent passage by vehicles and a second position, approximately 90 degrees from the first position, to permit passage by vehicles. A method of providing an operable vehicle barrier for use with a roadway includes providing a turntable device having a top surface, mounting at least one impact element on the top surface, and providing a drive system capable of rotating the turntable device in a plane that can be driven across by vehicles from the roadway.
