Delta Scientific Introduces Very High Security Barrier for Remote Locations

Unique Locking Mechanism Stops Terrorists from Lowering


VALENCIA, CALIF. – September 28, 2005 – Delta Scientific, the leading manufacturer of counter-terrorist vehicle control systems used in the United States and internationally, today introduced its new DSC501RL (Remote Locations) Very High Security Shallow Foundation Barrier that incorporates a new special locking system that prevents terrorists from disabling or dismantling it. It was created especially for remote applications, such as at dams and other out-of-the-way locales. In such locations, it is kept in the “up” position.

“According to the federal government, there is a growing need for high security vehicle access at many remote locations,” explained Delta Scientific Senior Vice President David Dickinson. “With the DSC501RL, the harder a terrorist works at attempting to immobilize this barrier to get a vehicle through, the tighter the unit actually locks up.”

Set in a foundation only 18 inches (46 cm) deep, the Delta DSC501RL will survive and operate after a 1.2 million foot pound impact. That’s equivalent to a 15,000 pound truck hitting it at 50 mph (66kN at 80 kph). Upon extracting the truck, the barricade will be fully functional and perform 27,000 cycles with no wear. It will also stop even larger trucks going faster.

With its shallow foundation and aesthetic design, it is a major breakthrough in high duty, anti-terrorist barricades. It obviates the concerns of interference with buried pipes, power lines and fiber optic communication lines. The shallow foundation also reduces installation complexity, time, materials and corresponding costs. The DSC501RL is suitable for high water table locations and areas with corrosive soils.

In the lowered position, the DSC501RL’s barrier ramp is completely flush with the roadway. Buttresses, counterweights and road plates do not obstruct authorized pedestrian or vehicular traffic. The DSC501RL is raised and lowered to and from the guard position via hydraulic cylinders driven by Delta’s patent-pending hydraulic power unit. This unit can be configured to operate one or more DSC501RL barriers and provide pass-through rates of 3 to 15 seconds, suitable for most inspection and identification station requirements. However, when danger is imminent, the barricade rises in less than 2 seconds!

The DSC501RL barrier is available now.
