Since 2009, K12 Defense has perfected the conversion process, utilizing Moog's linear servoactuator -- which use - in barriers - we introduced to Moog. Moog's design engineers were in our Arizona facility yesterday testing a new device in our wedge plate barriers. We have successfully converted over 50 wedge barrier with our EM+ system for the military and currently place our EM+ system in drop arm, other wedge barriers and gates. See www.k12defense.com
I think the video shows the need for one more feature, a net to catch the debris! The USN used to have a big wire mesh net to protect aircraft on deck from those that were in trouble during landings on a carrier. Modern carriers have an angled flight deck that precludes this requirement.
In the video the leading edge of the barrier is like a knife edge that slices into the moving vehicle. Perhaps a flat plate type front to absorb impact would result in less debris passing the barrier and shearing of the vehicle.
I would be interested to hear what some of the orginial design criteria were.
Chuck, this story is a great example of what good design engineering is all about. Here, Moog is taking a product that's come into increasing usage since 9/11 -- the roadway barrier for security -- and taking it to the next level with an elegant solution that replaces hydraulics with more reliable servo-motor control.
