Technical Highlights
MASH 2016 tested and approved
The TTMA-200 was successfully tested and passed all required MASH crash test criteria. The Federal Highway Administration (FHWA) eligibility letter was awarded in March 2019 and is filed as CC-152.
Patented energy absorbing technology
During a collision, the oversized mandrel pushes into a smaller tube, splitting it into four strips of metal to dissipate the impact energy. The metal strips remain with the trailer and pose no hazard to adjacent traffic.
Proven strength and versatility
Within minutes, the TTMA-200 can be attached to any support vehicle with a gross vehicle weight (GVW) of 10,000 lbs. or more. Only a standard eight-ton pintle hitch is needed, and there is no maximum weight limit.
