ABSTRACT:
A terrorist vehicle barrier is disclosed that is an improvement on the barrier shown in U.S. Pat. No. 4,576,507. The barrier consists of two vertical I-beams having cable passed between them to provide a barrier. An expanded aluminum honeycomb is provided between the I-beam and the cable passing around the I-beam to provide an effective shock absorbing structure. The barrier can be employed as an actuatable gate or as a fence-like structure around the perimeter of a installation to provide an esthetic and cost effective barrier strong enough to stop a high speed vehicle with minimum damage to the barrier.
