Safe-Stop® Trailer TMA Truck Mounted Attenuator - Model #9000

Products / T.M.A. / Safe-Stop Trailer Model #9000


The SST TMA is an innovative new concept that is changing how TMAs are used around the world. Speedy attachment mechanisms and heavy duty axle/wheels instead of typical TMA mounting hardware make the SST TMA the best value available today. The proven industry leading Safe-Stop TMA is designed as a trailer giving highway authorities the ability to rapidly deploy and maximize truck fleet utilization, thus lowering overall TMA operating costs. Special anti-rotational dampeners help ensure the SST TMA maintains optimal impact position to help protect impacting vehicles, at the same time protecting the host vehicle. The SST TMA also incorporates nuisance impact protection and has over 50% reusability after design impacts. This means the SST TMA will be back in service quicker with lower maintenance costs. Like all Safe-Stop TMAs, the SST TMA meets all standard and optional NCHRP 350 TL-3 test requirements to provide optimum protection to drivers, equipment, and the public.

NCHRP 350
  • Meets NCHRP 350 TL-3 criteria for standard and optional tests at 100 km/h (62 mph) for design impacts.
Speedy Attachment
  • Installation and removal of the SST TMA takes only minutes. The system installs on a standard 20 ton pintle hook.
Superior Design
  • The SST TMA features antirotational dampeners that are designed to lock the TMA in place during an angled impact to minimize the TMA from rotating into into adjacent traffic lanes. The anti-rotational dampeners do not affect driveability of the host vehicle.
Fast and Easy Refurbishment
  • After a typical design impact, the steel support frame and strike plate are reusable, and only the two aluminum Safe-Stop cartridges need to be replaced.
