TTMA-100 Trailer Truck Mounted Attenuator

Martin Aluminum Service Body


The TTMA-100 utilizes patented tube bursting technology to dissipate energy in vehicular impacts and protect motorists and workers in the instance of a crash. The structural tube rail members of the trailer also function as energy absorbers, thus simplifying the attenuator design and keeping the costs low.
