Delta Scientific, the manufacturer of counter-terrorist vehicle control systems, has announced that its HD2055 barrier which will stop a 15,000 pound (66.7 km) vehicle travelling at 50 mph (80 kpm) has just met the criteria of the United States Department of State for continuous operations of one million cycles.
The HD2055 solution was tested from February this year through until July. Testing was conducted in an external setting with exposure to full sunlight and the effects of climatic conditions. Cycle rate on the barrier was four per minute.
“This is another example of why vehicle access control solution buyers need to check for certified equipment,” emphasised Greg Hamm, Delta Scientific’s vice-president of sales and marketing. “Security professionals who need to protect their perimeters from terrorists and errant drivers must have the confidence that their barriers will perform their functions each and every time.”
According to the report by the independent test facility: “The barrier system was found to be capable of 1,000,000 continuous operations without failure of any component necessary for continued barrier operation outside of scheduled maintenance.”
Upon impact, the barrier remains in its foundation and the opening stays blocked, providing a multiple hit capability. In its M50 crash test, the HD2055 completely disabled the test vehicle, causing severe damage to the occupant department and power train. The maximum penetration recorded was less than zero.
The P1 penetration rating was given because the penetration beyond the protected side of the barrier was less than 1.0 metre at the lower leading edge of the test vehicle’s cargo bed.
With its 24-inch (61 cm) shallow foundation and aesthetic design, the HD2055 obviates the concerns of interference with buried pipes, power lines and fibre optic communication lines. The shallow foundation also reduces installation complexity, time, materials and corresponding costs. The HD2055 is ideally suited to high water table locations and areas with corrosive soils. It provides low maintenance as all components are accessible from the sides or top of the barrier.
For increased security, the HD2055 leverages Delta Scientific’s proprietary counter-balanced technology to provide a 1.5 second emergency fast operation, thus responding to attacks very quickly indeed.
