Patent attributes
There is provided a barrier system for stopping land-based and water-based vehicles from entering predetermined areas. The barrier system, which may protect relatively wide spans, is capable of stopping relatively high mass vehicles traveling at relatively high speeds. The barrier system comprises an anchoring system, vertical supports, an energy absorption unit, a gliding bar, and a net system. The gliding bar is selectively moveable relative to the energy absorption unit and may selectively define an unfixed mode wherein the gliding bar is moveable relative to the energy absorption unit and a fixed mode wherein the gliding bar is fixed relative to the energy absorption unit. The net system is connected to the gliding bar such that converting the gliding bar from the unfixed mode to the fixed mode raises the net system to prevent passage of vehicles.
