Component Details
Our Truck Mounted Attenuator (TMA) is a mobile crash cushion attached to the rear of a support vehicle’s frame. The TMA may be used on moving shadow trucks, stationary block vehicles, or advanced warning vehicles upstream of a moving or stationary operation. The TMA can be used on support vehicles with a minimum actual/curb weight of 15,000 lbs (6,804 kg) with no upper weight limit (infinite weight).
The TMA consists of three (3) main components:
The Strut and Cartridge are the energy attenuation components. The Strut is positioned nearest to the support vehicle and the Cartridge is positioned furthest away from the support vehicle. The Cartridge is typically the first component impacted by an errant vehicle. The Strut consists of four (4) outboard convex aluminum tubes (two on each side) forming an aluminum structural weldment. The aluminum structural weldments bolt to a structural steel diaphragm/backup frame.
