The new family of QuadGuard crash cushions offers the latest technology for shielding hazards 610 to 3048 mm (2′ to 10′). Each Quadguard System consists of crushable, energy-absorbing cartridges surrounded by a framework of Energy’s exclusive steel Quad-Beam™ panels. These new crash cushions redefine NCHRP 350, Test Level 3 performance for redirective, non-gating attenuators. The QuadGuard Systems have successfully passed the complete NCHRP 350, Test Level 3 test matrix with both the light car and high center-of-gravity pickup truck at speeds up to 100 km/h (62 mph) at angles up to 20°. Higher speed units are available. During head-on impacts, the QuadGuard Systems telescope rearward and crush the cartridges to absorb the energy of impact. When impacted from the side, the QuadGuard Systems safely redirect the errant vehicle back toward its original travel path without allowing gating.
The ACZ-350 System combines ease of use and NCHRP 350, gating, non-redirective TL-2 and TL-3 crash cushion performance for work zone protection. This partially reuseable crash cushion can be easily transported, and installed with No Roadway Anchors. The unique design of the ACZ-350 systems protects errant drivers from impacting concrete barrier ends, and also contains the errant vehicle from vaulting into the workzone.
