TRUCK MOUNTED ATTENUATORS HAVE ONE PURPOSE; TO SAVE LIVES.

TMA’s are predominantly used for protection for static worksites in high speed environments where there is a traffic/worker interface – such as construction zones – and as shadow vehicles for high risk mobile works such as line marking, maintenance, rubbish collection and barrier repairs on highways. They are compulsory in most Australian states.

THE TRUCK WITH MANY NAMES – a truck mounted attenuator is also referred to as a:

  • Cushion Truck
  • TMA Truck
  • Crash Truck
  • Scorpion Truck
  • Impact Attenuator Truck
  • Safety Truck
  • Traffic Control Truck

A TMA is a safety measure used to absorb full impact of crashes, to protect and save lives of road workers and motorists.

ArrowES specialises in the supply and installation of various compliant truck mounted attenuators ranging from Scorpion, Safe Stop 180° and Safe Stop SS90™, to name a few.

Trafix Scorpion TMA

Scorpion_TMA

The Scorpion TMA is designed to conveniently fold up and over the truck bed during transport and storage. The compact design and balanced weight distribution makes it ideal for high-speed travel. Provides impact protection up to 100 km/h.

The Scorpion TMA consists of strut and cartridge sections that are linked together on a support frame. The curved side rails are made from corrosion resistant aluminium tubes, which offer full width impact protection along the entire length of the unit. The side rails are designed to re-direct errant vehicles away from the rear of the truck (coffin corner).

The aluminium boxes are filled with a moisture proof, aluminium honeycomb material.

Upon impact the Scorpion TMA crushes in progressive stages. When hit by a lighter vehicle, the impact will crush the cartridge section, allowing only the cartridge section to be replaced.

Features & Benefits

  • The hydraulic system allows the cartridge to be partially raised for maximum road clearance and manoeuvrability
  • Scorpion’s low profile and open tubular design in beneficial in minimizing wind resistance and drag, allowing you to drive at freeway speeds safely, as well as increasing rear visibility and gas mileage
  • Scorpion’s lightweight aluminium construction minimizes rust and other corrosive elements.
  • With its modular design, Scorpion crushes in progressive stages upon impact thus reducing repair costs
  • Scorpion’s durable construction and heavy duty tubular side rails minimize incidental back-up or turning damage
  • The unique curved design redirects side angle impacts away from the exposed corner of the truck
  • Scorpion can be easily and quickly mounted to or removed from the truck

Specification

Model C-90 TL-3

The Scorpion TMA Model C-90 folds just past the 90-degree position (when folding over the truck bed is not desired). This feature allows for easy transit in the upright position. The rear strut is raised 10-degrees for added mobility and ground clearance, making it ideal for safely clearing exit ramps, driveways and other inclined surfaces in the stored or travel position. The Scorpion TMA Model C-90 provides TL-3 impact protection.

  • Weight: 1,975 lbs (900 kg)
  • Length: Travel/Storage 3′ 1″ (.94 m),
  • Length: Deployed 14′ 9″ (4.5 m)
  • Width: 8′ (2.45 m)
  • Height: Travel/Storage 14′ 2′ (4.32 m),
  • Height: Deployed 1′ (.3 m)
  • Tests Passed*: 3-50, 3-51, 3-52, 3-53

Model C TL-3

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.

  • Weight: 1,975 lbs (900 kg)
  • Length: Travel/Storage 2′ 5″ (.74 m),
  • Length: Deployed 13′ 10″ (4.21 m)

Safe-Stop 180° TMA

SafeStop_180

The Safe-Stop TMA with 180° Tilt feature provides maximum protection with minimal length, weight and height.  The 180° tilt feature makes this the shortest TMA available when in its storage mode.  The Safe-Stop 180° TMA successfully meets the NCHRP 350 TL-3 criteria, and also provides TL-2 protection when in storage (folded) mode.  It is recommended that the Safe-Stop TMA® be mounted to trucks between 16,090 lbs and 19,845 lbs for optimum impact performance.

Features & Benefits

  • When impacted, the steel support frame progressively collapses, allowing the aluminium cartridge to crush. This absorbs the errant vehicle’s impacting energy, bringing it to a controlled stop.
  • Hydraulically folds 180 degrees for easy storage and transportation.
  • TL-2 2000kg protection in ‘folded’ position (not small cars)
  • Withstands nuisance impacts of up to 10kph.
  • Refurbishment can often be completed in the field.
