Delta’s new electrically controlled barrier receives P1 rating at ASTM M50 test level

Delta Scientific’s latest HD 300 barrier, is available with either a fully electric or hydraulic control unit, and will stop a 15,000 pound (66.7 Km) vehicle travelling 50 mph (80 kpm). Upon impact, the barrier remains in its foundation and the opening stays blocked, providing a multiple hit capability. In its M50 crash test, the HD300 completely disabled the test vehicle, causing severe damage to the occupant department and power train. The maximum penetration recorded was an outstanding -1.8 m on the passenger’s side. The P1 penetration rating was given because the penetration beyond the protected side of the barrier was less than 1.0 m at the lower leading edge of the test vehicle’s cargo bed. “The HD300 provides many of the flexibilities that security professionals want in a vehicle access barrier,” explains Greg Hamm, Delta Scientific vice president, marketing and sales. “Besides being easy to install and providing a fast emergency fast operation, low maintenance and multiple hit capabilities, customers can select either our new all electric control unit or Delta’s lauded hydraulic control unit.”With its 24-inch (61 cm) shallow foundation and aesthetic design, the HD300 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 HD300 is perfect for 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 HD300 leverages Delta’s propriety counter-balanced technology to provide a 1.5 second emergency fast operation (EFO), responding to attacks very quickly. The electric actuator provides IP67 protection, meaning that the unit is totally protected against dust and as well as the effect of immersion between 15 cm and 1 m.

Delta Scientific, the leading manufacturer of counter-terrorist vehicle control systems used in the United States and internationally, recently announced that its new HD2055 electromechanically controlled anti-terrorist barricade decisively stopped the 15,000 pound (6,803 kg) test vehicle traveling at 51 (82 kph) in a recent crash test conducted by an independent testing laboratory. Less than zero penetration of crash barrier The HD2055 barricades not only stopped the vehicle but contained the test load representing the bombs strapped to the truck bed. The crash test result showed a less than zero penetration. “Significantly, the operating mechanism and cams were all intact and reusable after the dramatic crash test,” emphasises David Dickinson, Senior Vice President of Delta Scientific. “This level of survival is normally only seen with hydraulic barricade systems.” Easy-to-install shallow foundation The new HD2055 barricade features an easy-to-install shallow foundation with an environmentally-friendly electromechanical actuator which utilises a sophisticated 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, dramatically increasing the life of the lifting mechanism. The shallow foundation also obviates the concerns of interference with buried pipes, power lines and fibre optic communication lines. The HD2055 is perfect for 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. As with its hydraulic designs, the electromechanical HD2055 can be deployed as a single barricade in a narrow lane application or in extended arrays which cover wide roadways. Each HD2055 barricade can be open or closed individually or as a group to allow the passage of both small or large vehicles. Like other Delta Scientific products, the HD2055 can be remotely controlled via fibre optics, touch screen control panels, NEMA rated control button panels and simple key switches.
