Truck mounted attenuators are the latest safety device introduced to protect motorists, road construction and maintenance workers.
An impact attenuator is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision.
They are designed to absorb the colliding vehicle’s kinetic energy like a giant cushion. With construction and maintenance ongoing everywhere in Australia where there’s a road, a product innovation that improves safety for motorists and road workers is a significant one.
Coates Hire has recently taken delivery of two brand-new truck mounted attenuators (TMAs), fully compliant with all Australian state and territory regulations, with more to come nationally.
“The new TMAs are purpose-built trucks with automatic transmissions and air conditioning, making them extremely comfortable to drive and allowing the driver to remain focused on protecting his workers and plant,” says National Performance Manager – Traffic Management John Annison.
“The new TMAs are fitted with highly visible flashing beacons, an arrow board and VMS to help ensure motorists are alerted well in advance to the presence of the TMA and workers and plant on the road ahead.”
The truck has a demountable Scorpion attenuator attached to the rear, capable of decelerating and stopping vehicles generating 820 to 2000 kilogram impacts and suitable for use in 100 kilometre per hour zones. It is also fitted with a rear-facing LED message board and an arrow board to alert motorists and direct traffic through the work zone.
An automatic impact braking system, with the truck’s 15 tonne TVM, reduces the distance the TMA rolls forward in a collision, reducing risk to personnel at the front of the truck.
A four point harness seat belt adds to driver protection and the cab is equipped with two UHF radio, enabling communications with road crews and motorists on separate channels.
“All TMA functions, including raising and lowering the attenuator, programming the arrow board and VMS, activating beacon and the CCTV, are controlled from a console inside the cab of the truck,” Annison says.
Three video cameras aid visibility during reversing and help ensure clearance while raising and lowering of the Scorpion TMA. The vision from the cameras is recorded to a 500GB hard drive.
“With ever increasing traffic volumes and the need to work on live roads our new TMAs offer our customers the very latest in crash protection from errant vehicles,” he concludes.
