PALMDALE, CALIF. â€“ October 25, 2007 â€“ Delta Scientific, the leading manufacturer of counter-terrorist vehicle control systems used in the United States and internationally, today announced that its DSC 501 high security barricade has been tested in the United Kingdom to stop a 7,500 kg (16,500 pound) vehicle traveling 80 kph (50 mph), meeting the BSI standard PAS:68 2007, which tests barricades to a standard most similar to the U.S. State Departmentâ€™s K12 rating. After the crash, the DSC 501 continued to operate with no repairs, thus showing that it can protect facilities against a â€œsecond hit threatâ€ from an accompanying vehicle.
â€œWe were not surprised at this result because, almost two years ago, the DSC501 had earned a State Department certification of K54, far exceeding the K12 standard, stopping and destroying a 29,484 kg (65,000 pound) truck hitting it at 80 kph (50 mph),â€ emphasizes Delta Scientific Senior Vice President David Dickinson. â€œThatâ€™s a 5.4 million foot pound impact. Nonetheless, we are pleased to meet and exceed British standards, which are used by many international agencies in selecting vehicle control equipment.â€
Over 2,000 DSC501 high security barricades are in use throughout the world at embassies, nuclear power plants, DOD facilities and other critical threat locations around the world. With its shallow foundation and aesthetic design, it has become the major barrier for high duty, anti-terrorist barricades.
Set in a foundation only 18 inches (46 cm) deep, the DSC501 is suitable for high water table locations and areas with corrosive soils. The shallow foundation obviates the concerns of interference with buried pipes, power lines and fiber optic communication lines. This foundation also reduces installation complexity, time, materials and corresponding costs.
When a car going 60 mph (96 kph) is detected within 90 feet (27.6 m), the DSC501 raises in only one second, time for the barricade to provide protection. In the lowered position, the DSC501â€™s barrier ramp is completely flush with the roadway. Buttresses, counterweights and road plates do not obstruct authorized pedestrian or vehicular traffic. The DSC501 is raised and lowered to and from the guard position via hydraulic cylinders driven by Deltaâ€™s patent-pending hydraulic power unit. This unit can be configured to operate one or more DSC501 barriers.
The DSC501RL (Remote Locations) model 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 â€œupâ€ position. 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.
A debris screen is also available that reduces visual and physical access to the intra-barrier area for security and safety purposes. The screen will also deflect explosives, such as a hand grenade, from being thrown inside the barricade. This debris screen was tested to over 10,000 cycles with no measurable damage or wear.
