Technical Specifications

  • 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. (4,535.9 kg) or more. Only a standard eight-ton pintle hitch is needed, and there is no maximum weight limit.
