Advanced counter-terrorism barrier system for sub-surface conditions that negate extensive excavations

K12/L3 certification meets government’s highest levels…exceeds Department of State and Department of Defense requirements 

This barricade was designed for the U.S. Navy and has also been selected for use at U.S. Embassies.  Set in a foundation only 18 inches (46 cm) deep, the Delta DSC501 is able to survive and operate after a 1.2 million foot pound impact.  Upon extracting the truck after its crash test, the barricade was fully functional and performed a resounding 27,000 cycles with no wear!  

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 DSC 501 is suitable for high water table locations and areas with corrosive soils. 

Front face warning lights warn drivers that the barricade is in the “up” position.  There is also an open area on the front for signage.  Diagonal yellow and white stripes are standard and optional colors and graphics are available.  The open channel construction even lets you specify hot dip galvanizing.

In the lowered position, the DSC501’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 Delta’s patent-pending hydraulic power unit.  This unit can be configured to operate one or more DSC501's 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! 

A vehicle detector safety loop is available.
