Anti-terrorist barricade halts loaded truck in test (with related video)
The HD2055 electromechanically controlled anti-terrorist barricade from Delta Scientific has successfully passed an important test. The barricade decisively stopped a 15,000-pound test vehicle traveling at 51 mph in a recent crash test conducted by an independent testing laboratory. The barrier system not only stopped the vehicle but also contained the test load representing the bombs strapped to the truck bed. The crash test result showed a less than zero penetration. The photo to the right shows the barricade before the test. 
“Significantly, the operating mechanism and cams were all intact and reusable after the dramatic crash test,” says David Dickinson, Senior Vice President of Delta Scientific. “This level of survival is normally only seen with hydraulic barricade systems.”
The barricade features a shallow foundation with an environmentally friendly electromechanical actuator. The foundation is easy to install, according to the company.
The system uses a cam design that accelerates and de-accelerates the barrier road plate during raising and lowering. This reduces the lifting and closing force down to zero at the end of each stroke, which helps lengthen the life of the lifting mechanism.
The unit’s shallow foundation helps reduce concerns of interference with buried pipes, power lines and fiber optic communication lines. The barricade is suited for high water table locations and areas with corrosive soils. The unit is designed for low maintenance, as all components are accessible from the sides or top of the barrier.
The electromechanical HD2055 can be deployed as a single barricade in a narrow lane application or in extended arrays that cover wide roadways. Each barricade can be open or closed individually or as a group to allow the passage of both small and large vehicles.
The product can be remotely controlled via fiber optics, touch screen control panels, NEMA-rated control button panels and simple key switches.
The video shows the HD2055 electromechanically controlled anti-terrorist barricade successfully passing a crash test. Delta Scientific is the manufacturer.
