The U-MAD Truck Mounted Attenuator (TMA) provides positive protection for works personnel and motorists in a slow moving or stationary work zone.

The U-MAD is a true full width TMA providing full coverage to the rear of the support vehicle. This helps to keep the impacting vehicle in the impact zone, instead of redirection back into traffic or the work zone. In accordance with NCHRP 350, the U-MAD TMA (100km/h) has been independently tested to meet Test Level 3, (Test 50, 51) as well as optional tests 52 and 53 (off centre head on, off centre 10 degrees).

Advantages and Benefits

• Easy to use and maintain
• Various mounting systems, to suit different types of support vehicles
• Attenuator provides full width protection for support truck
• TMA is detachable, allowing the vehicle to be free for other use
• Quick and easy detachment
• TMA can be raised or lowered to any angle
• Can be fitted with various message or arrow boards
• The attenuator is supported on an “L lift” bracket rather than in suspension. This reduces vibration and eliminates stress damage on the unit and reduces wear on the support vehicle
• Steel corner protectors help eliminate damage
• Cab control for raising and lowering the unit
• The unit height provides a larger impact area for larger vehicles eg: 4WDs
