Abstract: The specification and drawing figures describe and show a vehicle restraining system that includes a truss assembly. A rotateable drum is repositionable on the truss assembly. A gravitationally deployable vehicle restraining device is removably attachable to the drum and to the truss assembly. At least one cable is disengageably connectable to the drum and to the truss assembly. A plurality of guide rods is installed on the truss assembly in opposing spaced-apart pairs, and a boom is provided that is repositionable on the plurality of guide rods. At least one motor is mountable on the boom for both repositioning the boom on the plurality of guide rods and for rotating the drum to enfold the gravitationally deployable vehicle restraining device on the drum.

Abstract: The specification and drawing figures describe and show an anti-vehicle security system that includes a truss assembly formed with a plurality of monolithic stanchions. A container having a hinged door is fixed on the truss assembly. The system also includes two spaced-apart guides that extend from within the container to a portion of the truss assembly in ground contact. A gravitationally deployable restraining device, which may be stored in and deployed from the container, includes sleeves, clips and keepers to deploy the restraining device to snare a vehicle.
