Scorpion® TMA Truck Mounted Attenuator 


Manual for Assessing Safety Hardware

The Scorpion II TMA from TrafFix Devices is the world's first MASH Tested, Passed, and Eligible Truck Mounted Attenuator.

Read Eligibilty Letter >

The Scorpion line of Impact Attenuators, by TrafFix Devices, Inc., are truly "different by design".

   The Scorpion TMA consists of strut and cartridge sections that are linked together on a support frame. The curved side rails are made from corrosion resistant aluminum tubes, which offer full width impact protection along the entire length of the unit. The side rails were designed to re-direct errant vehicles away from the rear of the truck (coffin corner). Other manufacturers Crash Attenuator models have little or no side-angle impact protection.

   The aluminum boxes are filled with a moisture proof, aluminum honeycomb material. The boxes, together with the curved side rails, absorb the energy from an impacting vehicle. The aluminum boxes are painted with a bright yellow powder-coated finish, for lasting durability.

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

 Scorpion Model C-90 TL-3

The Scorpion TMA Model B folds just past the 90-degree position (when folding over the truck bed is not desired). This feature allows for easy transit in the upright position. The rear strut is raised 10-degrees for added mobility and ground clearance, making it ideal for safely clearing exit ramps, driveways and other inclined surfaces in the stored or travel position. The Scorpion TMA Model B provides TL-3 impact protection.
