WHY BLADE AND HOW IT WORKS?

The TMA's strength comes from the composite aluminum welded profiles with 12 internal blades. During an impact, the first 4 blades cut through the aluminum composite H-beams and, after unlocking, 8 blades cut through the welded tubes. The remaining weak aluminum parts will bend away in safe directions. The patent is based on cutting aluminum H beams and tubes using BLADES.

WHY MASH?

The safety changes are mainly necessitated by alterations made to vehicles over the past decade. Cars have greatly increased in size, so different safety regulations are required to keep the occupants safe. The average bumper height on light trucks has risen considerably since 1993, so previous highway safety designs are no longer adequate.

HOW MASH DIFFERS FROM NCHRP-350?

The new MASH 2016 standard sets stricter criteria for Truck Mounted Attenuators. Bigger, heavier and newer vehicles are used during testing. Also, the shadow vehicle criteria is stricter and much heavier.  Upper and lower truck weight has to be tested, ballast has to be fixed and the arrow board together with the TMA construction must have been tested. The optional offset angle tests are now required in MASH!

#1 ON RESULTS

The patented BLADE TMA is the first full scale, crash-tested TMA according to MASH 2016 standards.   Testing was performed at the Texas Transportation Institute (TTI) with unbelievable results! All the ride down values were within the preferred ranges (MASH states a longitudinal ride down of 15.0 g with a maximum of 20.49 g). The BLADE is also full scale, crash-tested according the UK optional 110Kph test, TD49/07.
