Scorpion II Metro TL-2 Plus MASH Eligible Truck Mounted Attenuator70KM/H P/N 100BA-51111
The Scorpion II TL-2 TMA from TrafFix Devices is the world's first MASH Tested, Passed, and Eligible Truck Mounted Attenuator. The Scorpion II TL-2 Truck Mounted Attenuator is hydraulically powered and is ideal for stationary and mobile construction zones. Available exclusively in Australia from A1 Roadlines.
The Scorpion II Metro TL-2 Truck Mounted Attenuator (TMAs) from TrafFix Devices was the world's first MASH Tested, Passed, and Eligible Truck Mounted Attenuator.
TMAs are designed to protect workers and motorists from impacts with stationary or slow-moving trucks utilised in work zones and maintenance operations. The TMA is mounted to a shadow vehicle for purposes of protecting the work crew in front of the shadow vehicle and protecting the motorist that might drive into the lane closed off by the shadow vehicle.
MASH 2016 TESTING REQUIREMENTS
MASH 2016 Sections 220.127.116.11 and 18.104.22.168 defines support vehicle selection for TMA testing procedures. "During a TMA crash, the support truck is accelerated forward as the impacting vehicle is decelerated. Hence, the total velocity change during a TMA impact is strongly related to the mass of the support truck. Heavier support trucks will produce higher impacting vehicle velocity changes and require greater energy dissipation by the TMA. On the other hand, support trucks that are too light could produce high accelerations for the operator and excessive roll-ahead distance, which is the length of travel of the support truck during the impact".
TESTS 50 and 51 - Both tests should be conducted with the heaviest allowable support truck or a rigidly blocked support truck for no upper support-truck weight limit.
TEST 52 - Test should be conducted with the heaviest allowable support truck or a rigidly blocked support truck for no uper support-truck weight limit ("infinity weight)".
TEST 53 - Test should be conducted with the lightest allowable support truck.
SCORPION II TESTING
The Scorpion II Metro TL-2 TMA was tested as per MASH 2016 requirements with the support vehicle blocked to simulate a support vehicle of very high weight or "infinite weight". By doing so required the Scorpion II TMA to dissipate 100 % of the impacting energy without the benefit of forward roll. As a result the MASH Scorpion II is the only Truck Mounted Attenuator to have been tested and passed to infinite weight.
Infinite Weight Eligible - Can be used on a host truck vehicle weight of only 3,402 kg with no upper weight limit (infinite weight).
Curved Aluminium Tube Frame - Exceptionally strong, providing protection against nuisance impacts with re-directional capacity along the entire length of the TMA.
Energy Absorbing Cushions - Moisture proof aluminium honeycomb core, enclosed by aluminium powder coated modules providing maximum durability and longevity.
Modular Design - When impacted, the Scorpion II crushes in progressive stages, which results in lower repair costs and easy parts replacement.
Open Cartridge Design - Reduces wind resistance and increases fuel efficiency in storage and transport mode.
Full Width Impact Protection - Safely protects and redirects the impacting vehicle away from the "coffin corner" area at the rear of the truck.
