Truck Mounted Attenuators

Protecting vehicles and workers in the event of an impact.


Avoiding serious damages in case of impact, while protecting equipment, workers, and motorists.

Truck mounted attenuators are essential for securing a roadwork site where workers have to operate near traffic. Although a truck of a certain mass is necessary to protect workers, it is equally necessary to protect road users from a collision with this mass. The truck mounted attenuators help to reduce the risk of important damage in the event of a collision between a road user and the protective truck.


Efficiently protecting workers and equipment on construction sites.

When planning road works, it is essential to ensure protection for workers. Using truck mounted attenuators is not only required by standards, but it also is in many cases the best way to protect the workers’ well-being. Even though these attenuators do not protect a construction site laterally, it is essential for short term work, when setting up signage for example.
