Delta Scientific, a manufacturer of counter-terrorist vehicle control systems used in the United States and internationally, announced that 21 Delta MP5000 mobile deployable vehicle crash barriers will be used by the Secret Service at the upcoming Republican Convention running July 18-21 in Cleveland. 
The certified crash vehicles will protect attendees from terrorist vehicle attacks and errant driver mistakes. Provided through Global Access Control Systems (Pittsburgh), these mobile deployable vehicle crash barriers carry a K8 rating (M40 ASTM rating), stopping 7.5 ton (6400 Kg) vehicles traveling 40 mph (64 kph). 
“This is just the latest in a series of highly publicized events that leverage our mobile barriers,” said Greg Hamm, Delta Scientific vice president of sales and marketing. “They were at both political conventions in 2012 in Tampa and Charlotte as well as at the following Inauguration. They’ve also protected international dignitaries at recent G20, Nuclear and NATO Summits. Last September, they protected the Pope on his visit to the United States.”
In Cleveland, the totally self-contained MP5000s will be towed into position to control vehicle access within 15 minutes. No excavation or sub-surface preparation is required. Once positioned, the mobile barricades will unpack themselves by using hydraulics to raise and lower the barriers off their wheels. DC-powered pumps will then raise or lower the barriers.
Delta always keeps an inventory of the MP5000s for purchase and quick delivery at their manufacturing facility in Palmdale, Calif. In many cases, they are needed for events that come up quickly, such as politician or celebrity visits and other unexpected incidents, the company reported in a press release.
