Retractable Vehicle Barriers for Area Denial and Security

The National Sign and Signal Model 400 retractable vehicle barriers were developed through a Department of Defense research grant to provide complete area denial and area security protection. Certified by the United States Department of State to stop a 30,000 lb. vehicle traveling at 50 mph, the K12-rated Model 400 barriers are used as a first line of defense for valuable assets and high-speed crossings. These innovative barriers are self-contained, eliminating the need for a central pump station and making the barriers uniquely easy to install, operate and maintain.

Notable Features:

Engineered to stop a 30,000 lb. (13,608 kg) vehicle traveling at 50 mph (80 kph)
High-strength steel pylon withstands high-speed vehicle impacts with minimal or no damage
Self-contained, independent hydraulic power system in each barrier eliminates the need for a central hydraulic pump station and underground lines
Rapid-response barriers fully deploy in six seconds in normal operation mode and in less than two seconds in optional emergency operation mode
Low power requirement – control box on 110VAC or solar power, underground pylons on 24VDC – provides easy and low-cost operation
Integrated bilge pump, sealed motor housing, and all-weather hydraulic fluid provide environmental protection and ensure reliable operation in extreme climates
Independent battery back-up system in each barrier ensures reliable operation during power outages
Engineered, prefabricated, steel-reinforced foundation make installation of barriers quick, easy, and cost-effective
Self-leveling installation braces allow the barriers to be installed and leveled from road grade
Retractable delineators can be seamlessly integrated with new or existing traffic and/or perimeter security/access equipment, including traffic signs and loop detectors, motorized gate arms, digital video networking systems and a variety of other vehicle sensors
Retractable delineators can be controlled and monitored through a direct connection, or wirelessly utilizing high-speed ethernet radio or satellite
