Truck Mounted Attenuators

Truck-MountedAt Elgin Sweeping Services, we have many trucks mounted with Safe-Stop attenuators. These attenuators are designed to reduce the severity of accidents and crashes that can occur in work zones. Our attenuators meet all NCHRP 350 TL-3 requirements for 100 km/h (62 mph) impacts. Our Safe-Stop TMA is only 3.98 m (13'2'') long yet it protects against very high speed impacts.


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, bringing the vehicle to a safe, controlled stop and preventing it from underriding the truck

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. Refurbishment can often be done in the field.
