Impact Attenuation

T

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

Don’t just think your workers are protected while on the job site, know that they are with the Scorpion II TMA from TrafFix Devices.

After 17 years on the road, over 2,000 documented impacts, and thousands of lives saved across the globe, the Scorpion TMA’s Patented design is the safest and most reliable Truck Mounted Attenuator available today!

The Scorpion II TMA consists of strut and cartridge sections that are linked together on a support frame. This open cartridge design reduces wind resistance and increases fuel efficiency when deployed on the job site and when traveling at highway speeds. Each energy absorbing cushion has an Aluminum honeycomb core that is enclosed by aluminum powder coated box module that provides maximum durability and longevity. The Scorpion II is equipped with omnivolt LED brake, directional, signal and running lights to further enhance advanced warnings to drivers.

When impacted, the Scorpion’s modular design crushes in progressive stages, which reduces the impact forces on the vehicles occupants and results in lower repair costs and easy parts replacement. The curved side rails are made from corrosion resistant aluminum tubes and offer full width impact protection along the entire length of the Scorpion II by safely redirecting the impacting vehicle away from the deadly “coffin corners” at the rear of the truck. Unlike the Scorpion II, most other manufacturers Crash Attenuator models have little or no side-angle impact protection.

When fully deployed, the Scorpion II TMA is only 13′ (4 m) in length, compared to other manufacturers units which are over 19′ (5.8 m), thus giving the Scorpion II the shortest overall length of any MASH Eligible Truck Mounted Attenuator on the market. This shorter length reduces incidental impacts and repair costs while still providing the best safety and reliability you have come to expect from the Scorpion line of crash attenuators.

The Scorpion II is MASH Tested and Eligible with a minimum host truck vehicle weight of only 15,000 lbs (6,804 kg) with absolutely no upper weight limit. This is the widest range of host truck vehicle weights of any MASH Tested and Eligible Truck Mounted Attenuator currently on the market.

The Scorpion II TMA is the world’s first Truck Mounted Attenuator eligible for MASH, TL-3 tested at 62.5 mph (100 kph); see FHWA Eligibility Letter CC-132 for details.

Additionally, the Scorpion II TMA is compatible with the Doctor Air Brake® automatic braking system that instantly locks the brakes of the host vehicle upon impact, further protecting the driver of the TMA truck, occupants of the impacting vehicle, and any bystanders or workers near the crash.

The Scorpion Towable Attenuator requires little or no modification to host vehicle or additional mounting hardware beyond the standard pintle hook and ½” thick × 32″ wide steel frame plate. This single point attachment makes the installation of the Scorpion II TA quick and easy.

When impacted, the Scorpion’s modular design crushes in progressive stages, which reduces the impact forces on the vehicles occupants and results in lower repair costs and easy parts replacement. Rear axle placement improves attenuator stability and prevents the tail from “bottoming out” on driveways and uneven surfaces. The overall length of the Scorpion II TA is only 17′ 10″, the shortest on the market. The integrated electric brake system comes standard on all Scorpion II Towable Attenuators and are automatically activated in the event of attenuator separation or hitch failure. The Scorpion II is equipped with omnivolt LED brake, directional, signal and running lights to further enhance advanced warnings to drivers.

The Scorpion II TA can be used on support vehicles with a minimum curb/actual weight of 12,000 lbs with no upper weight limit (infinite weight). With the Telescoping Anti-Rotational System (TARS), the Scorpion II TA remained attached to the host vehicle and pintle hook during all impact testing. TARS minimizes the rotation of the Scorpion II during angled and offset impacts and prevents the attenuator from separating from its host vehicle.

The curved side rails of the Scorpion II TA are made from corrosion resistant aluminum tubes and offer full width impact protection along the entire length of the Scorpion II by safely redirecting the impacting vehicle away from the deadly “coffin corners” at the rear of the truck. The Scorpion II Towable Attenuator is the world’s first and only MASH Tested, Passed, and Eligible for TL-3 applications, with and without with optional display panels or message boards; see FHWA Eligibility Letter CC-138 for details.

Telescoping Anti-Rotation System (TARS™)


Pre-Impact Condition

The Scorpion Towable Attenuator attaches directly to the pintle hook. It does not require additional installation, or truck modification, beyond standard factory installed pintle hook and ½” steel frame plate.

Post-Impact Condition

Upon impact, two heavy anti-rotation arms are driven against the frame plate, preventing angular rotation of the Scorpion Towable Attenuator during an accident.

-With both of the units above it is important to note they are MASH testes, Passed and Eligible. There are MASH letters on the Traffix Devices website if you think we might want to include that.
