Safety Design Division.; Ensco, inc.;] -- This study investigated the impact performance of inertial barrel and GREAT (Guard Rail Energy Absorption Terminal) impact attenuator systems using full scale crash testing of small and large test. The TrafFix Devices "Big Sandy" is an Impact Attenuator Sand Barrel that is manufactured from UV stabilized high density polyethylene. The Big Sandy sand barrel is MASH Tested, Passed and Eligible and meets the crash worthy requirements of NCHRP

    The QUEST® is a redirective, non-gating crash cushion that consists of a series of W-beam fender panels supported by diaphragms and features an integrated front trigger mechanism. The system is tested to NCHRP Report Test Level 2 and Test Level 3. The QUEST® crash cushion can be used to shield fixed objects of 24” to 36” ( mm to mm) wide. +The Yodock Model is a lightweight portable plastic traffic control device. It is utilized to assist in prevention of vehicular penetration in workzone areas, street closures and provides delineation for traffic channelization pedestrian safety.

Impact Absorption Inc. of Plainview, New York, distributes crash cushions like the Tau-II ® Redirective Attenuator and also trailer-mounted attenuators to protect your road workers.

Our road Impact attenuators book equipment company creates cost-effective barriers and crash cushions for your needs. Let us show you how we can help you with our X-Tenuator Ground Attenuator. An impact attenuator, also known as a crash cushion, crash attenuator, or cowboy cushion, is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision.

Impact attenuators are designed to absorb the colliding vehicle's kinetic energy. They may also be designed to redirect the vehicle away from the hazard or away from roadway machinery.

The QuadGuard ® II consists of an engineered steel nose and crushable, energy absorbing cartridges surrounded by a framework of steel Quad-Beam panels.

The system is NCHRP Test Level 2 and Test Level 3 compliant as a redirective, non-gating crash cushion. The TL-2 QuadGuard II is 25% shorter than the original QuadGuard measuring less than 10’ (3 m) and the TL-3 model is 3’ (1 m.

Impact attenuators are a common sight across the nation’s highways. They are installed to offer additional protection to structures, motor vehicles, their occupants, as well as highway construction workers. The Manual on Uniform Traffic Control Devices (MUTCD) defines impact attenuators as “systems.

An impact attenuator accepted as a TL3 device is also acceptable as a TL2 device. Reusable Impact Attenuators can be used as a substitute for Expendable Attenuators. Vendor is responsible for providing appropriate transitions when required, to be paid for under the attenuator pay item.
