National Sign’s retractable vehicle barriers were developed to address the need for intelligent area denial, perimeter security and traffic control applications. The Model 400 barriers are K12- and PAS 68-rated and are certified by governments in the United States and the United Kingdom to stop a 15,000 lb. vehicle traveling at 50 mph. The barriers deploy fully in less than 6 seconds in normal operation mode, and in less than 2 seconds in emergency operation mode. IPS Model 400 barriers are self-contained, eliminating the need for a central hydraulic pump station or underground lines. Each barrier has an independent Parker Hannifin hydraulic power system and all electromechanical components are housed directly next to each barrier, providing environmental protection and ease of access for maintenance or replacement.
