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.
