Patent attributes
A vehicle barrier is formed with a barrier gate mounted on a pair of opposing lift arms pivotally connected via pivot shafts to a support structure. A plurality of endless bands are looped around the opposing pivot shafts and positioned to pass through compartments in the barrier gate. The lift arms and the barrier gate may be fabricated from lightweight material, such as thin steel, aluminum or plastic, so that the stopping power of the vehicle barrier is provided by the anchored bands. In permanent or portable configurations, the lightweight barrier gate can be quickly raised by hydraulic cylinders, or other appropriate means, into a deployed position to interfere with the passage of a vehicle over the barrier. The anchoring of the bands at ground or below ground locations on both sides of the barrier provides stopping power without requiring massive barrier structures to be raised and lowered in use.
