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. Meets NCHRP 350 TL-3 criteria for standard and optional tests at 100 km/h (62 mph) for design impacts.





Safe-Stop 180 Model #9182

Two light-weight aluminum cartridges are contained in a reusable steel support frame. When impacted, the steel support frame is designed to collapse and the aluminum cartridges crush to absorb the energy of the impact, bringing the vehicle to a safe, controlled stop and preventing it from underriding the truck. The Safe-Stop 180º TMA’s cartridges fold at the center, reducing the total system’s height to just 2.08 m (6’10”). The two cartridge sections literally stack on top of each other.





Safe-Stop Model #8291

Two light-weight aluminum cartridges are contained in a reusable steel support frame. When impacted, the steel support frame collapses and the aluminum cartridges crush to absorb the energy of the impact, bring the vehicle to a safe, controlled stop and prevent it from underriding the truck. Was subjected to all four mandatory and optional tests recommended in the NCHRP 350 report.





Alpha 100K TMA #8190

The Alpha 100K TMA is designed for easy transport to work sites and provides superior maneuverability. Two cables support the cartridge to reduce vibration and movement during transport, providing a smooth ride. 




Alpha 60

Durashell Nose returns to original shape after low-speed nuisance hits. The tapered nose also minimizes corner damage and streamlines appearance. Unique design of crushable aluminum absorbs rear-end impacts at speeds up to 97 km/h (60 mph) and prevents impacting vehicles from underriding truck. Utilized around the world for high speed Truck Mounted Attenuator (TMA) protection. Meets NCHRP 230.




Alpha 70K

Durashell Nose returns to original shape after low-speed nuisance hits. The tapered nose also minimizes corner damage and streamlines appearance. Unique design of crushable aluminum absorbs rear-end impacts at speeds up to 70 km/h (43 mph) and prevents impacting vehicles from underriding truck.






Alpha-2001

Durashell® Nose returns to original shape after low-speed nuisance hits. The tapered nose also minimizes corner damage and streamlines appearance. Thousands of the Alpha 2001 MD Truck Mounted Attenuator (TMA) Systems have been successfully used to make work zones safer around the world. Meets NCHRP 230.





LS-Pro

Economically designed to shield workzone vehicles during low speed impacts. The LS-Pro TMA is ideal for use on municipal vehicles, utility maintenance vehicles, snow plows, street sweepers, etc. when anticipated impact speed are at or below 50 km/h (30 mph). Durashell Nose returns to original shape after low-speed nuisance hits. The tapered nose also minimizes corner damage and streamlines appearance.






Quick-Mount System

Ease of attachment allows a truck to quickly hook up and act as a shadow or barrier vehicle. It also allows the unit to be unhooked just as quickly so the vehicle can be back in service on another job that does not require TMA protection. The TMA can be transferred from one vehicle to another to maximize productivity with the fleet.





Vorteq Trailer

The Vorteq TL-3 Trailer TMA is an innovative attenuator efficiently designed to meet both mandatory & optional NCHRP 350, Test Level 3 requirements. Acceptable host vehicle weight is 9960lbs to infinite weight. No modifications are required of the host vehicle.





MPS-350

The MPS-350™ (Mobile Protection System 350) is for use on stationary or moving shadow or support vehicles and is the first truck-mounted attenuator to pass NCHRP Report 350 Test Level 3. It has an open design and all-steel construction of functional components. The MPS-350™ design is a new concept that eliminates crushable cartridges.
