ABSTRACT:
A light weight, high strength cable supported by a longitudinal device that is capable of stopping a 15,000 lb vehicle at speeds exceeding 30 mph and provides for manual operation by one (1) person, whereas the barrier may pivot, move vertically, or swivel horizontally to control vehicle passage. Typically, the cable is embedded within a longitudinal support device and remains concealed. During normal operations where the vehicle barrier is moved, there is no tension on the cable and it remains unfastened. If a vehicle impact occurs, the cable immediately engages and fastens to the end support structures to resist vehicle impact forces. The light weight cable and longitudinal support device provides span distances exceeding 24 feet across a vehicle travel path, while requiring only one (1) person to manually move the barrier. The light weight cable and longitudinal support device also minimizes the counterweight size. The barrier may be moved by an operator from either side of the vehicle travel path. Both fixed and unfixed end support structures may be utilized. Non-rotating energy absorbing compression springs may be utilized to enhance the vehicle stopping capability.
