Truck mounted attenuator – TMA-02

A truck mounted attenuator (TMA) is used to establish an optimal and safe traffic situation for motorists and roadworkers. Thanks to a 100K attenuator, a work space is created, which ultimately results in an improved traffic flow. The TMA can be used on highways and regional roads.

Rapid low-cost repairs thanks to a modular structure

The chassis and 100K attenuator of our TMA are both modular. In case of a collision or damage, the repair costs are lower and the repair time is shorter compared to a fully welded chassis.

We have all parts available in stock and we can dispatch throughout Europe. Our 100K attenuator can be spray painted and dispatched within one workday. You can mount the attenuator independently on your TMA.

The 100K TMA crash cushion is easy repairable thanks to the modular structure Both the 100K attenuator and the chassis are modular.

TMA-02-A – A truck mounted attenuator with warning arrow

The upper frame of our TMA-02-A is completely constructed from galvanised aluminium. An warning arrow, with 12 alternating energy efficient LED lights, is mounted onto the upper frame.

Below this LED arrow an adjustable arrow traffic sign is mounted, which adjusts to the designated direction of the LED arrow. On the lower part of the frame a hydraulic pump unit and the batteries are mounted in lockable control boxes.

TMA-02-I – A truck mounted attenuator with LED display

An energy efficient ECO LED display from Swarco is mounted in the upper frame of our TMA-02-I. This enhances your visibility during roadworks.

Furthermore, the upper frame of our TMA has multiple functionalities e.g. different traffic signs, bespoke texts and the ability to switch rapidly.

Produced in accordance with CE and NCHRP 350 regulations

Our 100K attenuator has been produced in accordance with the American NCHRP 350 regulations, which ensures that the TMA is safe in multiple worst-case crash scenarios. Furthermore, does our TMA have a CE marking, which ensures that it complies with all relevant European legal requirements.

In order to make the TMA more visible to motorists at night, it is possible to illuminate the TMA with multiple LED spotlights. For this we use a pneumatic LED lamppost.

Built according to CE-marking and NCHRP-350 TL-3
