What is truck mounted attenuator?

What is truck mounted attenuator?

The truck mounted attenuator (TMA) is a safety apparatus welded or bolted on the rear side of a work truck. The sizes of the TMA vary but most are at least 1.5 meters wide as the purpose is to reduce the impact of an automobile collision.

How does a truck attenuator work?

In the case of a vehicle colliding with the attenuator mounted on the truck, the collision will generate significant G-force. The attenuator absorbs some of this G-force and kinetic energy generated by the collision, reducing the likelihood of serious injury and death.

What is an attenuator in a car?

An impact attenuator, also known as a crash cushion, crash attenuator, or cowboy cushion, is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision. Impact attenuators are designed to absorb the colliding vehicle’s kinetic energy.

What does TMA truck stand for?

Truck Mounted Attenuator
WHAT IS A TMA TRUCK? TMA stands for Truck Mounted Attenuator. An attenuator is the kinetic absorption device that absorbs impact when hit. In simple terms, it’s a crash cushion that is mounted to the rear of a safety truck.

What’s the definition of attenuator?

Definition of attenuator : a device for attenuating especially : one for reducing the amplitude of an electrical signal without appreciable distortion.

What are Scorpion traffic devices?

The Scorpion II Truck Mounted Attenuator (TMA) is a mobile crash cushion attached to the rear of a support vehicle’s frame. The TMA may be used on moving shadow trucks, stationary block vehicles, or advanced warning vehicles upstream of a moving or stationary operation.

What does attenuator mean?

What are the scorpion trucks?

The Scorpion TMA Model C folds up and over the bed of flat bed, stake bed, or dump trucks. The Model C with its compact design and balanced weight distribution makes it ideal for high-speed travel. The Scorpion TMA Model C provides TL-3 impact protection. Side mounts are also available.

What are the types of attenuator?

Types of Attenuator

• Fixed Type. In Fixed type attenuators the resistor network is locked at a predetermined attenuation value.
• Step Type. These attenuators are similar to fixed attenuators.
• Continuously Variable Type.
• Programmable Type.
• DC Bias Type.
• DC Blocking Type.
• Optical Attenuators.

Are attenuator trucks New Jersey DOT approved?

State work zone regulations often specify a minimum buffer barrier between the attenuator truck and the work area, and a minimum mass for the TMA truck, to minimize the chances that it will be pushed forward by a crash into the workers or machinery. All our Attenuator Trucks are NJ DOT Approved.

The truck-mounted Scorpion Attenuator consists of strut and cartridge sections that are linked together on a support frame. The curved side rails are corrosion resistant aluminum tubes, which offer full-width impact protection along the entire length of the unit.

What are the verdegro attenuators tested to?

The Verdegro Attenuators are tested to (NCHRP350 TL-3 & MASH TL-3) that meet all work zone safety requirements, are intended to absorb the impact of a high (or low) speed crash, decrease damage made to the vehicle, and save workers’ lives. The truck mounted attenuator (TMA) is a safety apparatus welded or bolted on the rear side of a work truck.
