What is an Attenuator Truck?

THE ANSWER:

An Attenuator Truck reduces injuries and saves lives of motorists and construction workers in work zones. It acts as a protective cushion device intended to absorb high-energy kinetic impact.

Attenuator Trucks are parked in front of fixed and temporary structures at road construction projects on highways, diversion intersections, crash barriers, and overpass supports.

Truck-mounted attenuators (TMA), are mounted on specially fabricated trucks to be struck from behind, and absorb vehicle impact. State work zone regulations often specify a minimum buffer barrier between the attenuator truck and the work area, and a minimum mass for the TMA truck, to minimize the chances that it will be pushed forward by a crash into the workers or machinery.

The TrafFix Devices' Scorpion TMA has been tested and has PASSED ALL optional and mandatory requirements suggested in the NCHRP-350 Report

TMA Truck Mounted Attenuator by Scorpion®

Truck-mounted attenuators use crushable materials that create a crumple zone, absorbing energy from crashed. The truck-mounted Scorpion Attenuator consists of strut and cartridge sections that are linked together on a support frame. The curved side rails are corrosion resistant aluminum tubes, which offer full-width impact protection along the entire length of the unit. The side rails re-direct errant vehicles away from the rear of the truck (coffin corner).

The TrafFix Devices’ Scorpion TMA has been tested and has PASSED ALL optional and mandatory requirements suggested in the NCHRP-350 Report (https://www.traffixdevices.com/standards/nchrp350) for TL-3. Additionally, the Scorpion TMA has passed the UKTD49, 110 km/h (68 mph) test. The Scorpion TMA has successfully passed a “worse case” side angle re-directive impact test – this goes beyond all governmental testing requirements. Full details available upon requestt.
