A great danger threatens the life of the road worker. When workers are on the road for maintenance, they may not find systems to protect them from cars, so they are limited to using traffic cones to alert passing cars.

That’s why we designed the TMA

What is the TMA system?

A Truck Mounted Attenuator (TMA) is an energy-absorbing device attached to the rear of a truck or utility vehicle. A TMA is designed to provide a controlled stop of a vehicle impacting the truck’s rear. TMAs have been used since the mid-1970s to reduce the severity of impacts between errant motorists and slow-moving or stopped shadow vehicles used to protect highway maintenance workers.

What speeds does the TMA overcome?

The National Cooperative Highway Research Program Report 350 (NCHRP 350) specifically addresses the performance requirements of TMAs. The recommended tests for TMA crash performance are defined for two different Test Levels. The basic Test Level, TL-2, is conducted at a nominal impact speed of 70 kph. TL-3 is the highest test level and is conducted at 100 kph. This report presents the manual for the Verdegro TMA, type US, at the more demanding NCHRP 350 TL-3 test conditions.

What are the components and parts of a TMA device?

The TMA device consists of a basic part, which is important in reducing vehicle collisions and protecting workers. It is amply equipped with features that promote safety. By inspecting it, the quality, efficiency, and safety of the improved.

Absorbing collisions cushion

The cushion is the main part of the device that can reduce the risk of collision and stop colliding vehicles, thus fully protecting workers on the road.

Warning Signs

A warning sign indicating the presence of a work zone in this area is mounted on the device and covered with reflective films to enhance visibility, minimizing the chance of collision with the device.

Under the support frame are two tubes to lift the complete system with a forklift, for example, to mount on the truck.

All exposed steel surfaces on the shall be primed, painted, or galvanized.

The shall be assembled with commercial-quality bolts, nuts, and washers that conform to European standards.

How did Shawahid manufacture the TMA device to ensure traffic safety?

Shawahid Industrial Roads Co. worked in the previous years to achieve traffic safety and protect lives in the Kingdom of Saudi Arabia and then launched to the Middle East after its success and leadership in the field of traffic safety in the Kingdom, which made it one of the first companies that provide excellent service with the efficiency of its systems and global accreditation.

As we used to design traffic safety systems with the best quality and equip them to fulfill their role on the roads, we issued the shock absorber, which can be supplied globally, so it is necessary to write to us through the fastest way for you.
