Dragnet median barrier

 

 

 

The Dragnet Median Barrier and Work Zone Net System is comprised of a chain link net assembly with single energy absorbers attached to each end. The energy absorbers are supported by anchors, which can be mounted into their own concrete foundation or directly to a concrete median divider.

The variables involved with determining the stopping distance and "g" load response of a system are vehicle weight, vehicle speed, and net width. A 1,800 pound vehicle impacting a 30-foot wide net at a speed of 62 mph will stop in approximately 39 feet with an average deceleration of of approximately 3.3 g's. A 4,500 pound vehicle impacting a 30-foot wide net at a speed of 62 mph will stop in approximately 83 feet with an average deceleration of approximately 1.6 g's.
