ABSTRACT:
A vehicle barrier system that stops unwanted vehicle intrusion, controls vehicle access, and protects assets and critical infrastructure. The vehicle barrier system, which can span up to 250 feet without requiring fixed intermediate supports, will stop a 15,000 lb vehicle traveling at impact speed of 50 mph. The barrier net is attached to vertical steel end supports anchored in concrete, and include energy absorbers, pivoting connections, and force equalization bars. The barrier net can remain in the “up” or “down” position, and can be raised or lowered using a winch powered by common 12 volt battery with solar power recharge. The barrier net and system components are modular, and can be easily installed or removed.
