When your crew works in or near live traffic, a Truck Mounted Attenuator (TMA) is the barrier between a moving vehicle and your people. It absorbs the energy of an errant vehicle’s impact, protecting both the work crew ahead and the driver behind.<\/p>\n\n\n\n
As an authorized TrafFix Devices Scorpion distributor, Quality Truck Bodies brings the industry’s leading attenuator together with 50 years of in-house body building and upfit. We don’t just supply the unit \u2014 we mount it, wire it, and can deliver a complete, work-ready crash truck. Because every unit is ordered and built to your specification, you get the right configuration for your trucks, your speeds, and your jobs.<\/p>\n\n\n\n
We start with your chassis (or help you spec one), build the body, and integrate the Scorpion TMA, lighting, and arrow board into a single, turnkey unit. One vendor, one build, one point of contact \u2014 delivered ready to work.<\/p>\n\n\n\n
Already have the truck? Bring it to us and we’ll mount a Scorpion TMA to it. We handle the mounting plate, actuation, wiring, and lighting integration so your existing fleet vehicle becomes a compliant crash truck.<\/p>\n\n\n\n
The flagship truck-mounted unit. Per TrafFix, the world’s first MASH-tested, passed, and eligible TMA, rated to TL-3 at 62.5 mph. It has one of the shortest deployed lengths on the market (about 13 ft) and a low minimum host-truck weight of 15,000 lbs with no upper limit, so it fits a wide range of trucks. The open-cartridge design reduces wind resistance for better fuel economy at highway speed.<\/p>\n\n\n\n
A MASH-tested and passed TL-2+ unit for posted speeds up to 50 mph \u2014 ideal for cities, counties, and urban districts where TL-3 isn’t required and a more compact, lower-cost option makes sense.<\/p>\n\n\n\n
For crews that want to protect a work zone without dedicating a truck body to it. Per TrafFix, the first and only MASH-eligible TL-3 towable attenuator (FHWA letter CC-138), approved up to 62.5 mph. It tows behind a support vehicle with a standard pintle hook and frame plate \u2014 no special truck modification \u2014 and its integrated electric brakes engage automatically if the trailer separates.<\/p>\n\n\n\n
Many state DOT and federal work-zone specifications require a crash-rated attenuator on shadow and work vehicles in specific situations \u2014 particularly mobile operations and lane closures on higher-speed roadways. Beyond the requirement, a TMA is simply the most effective way to protect a crew and the traveling public from rear-end impacts.<\/p>\n\n\n\n
Common applications include paving, striping, and line-marking operations; mobile maintenance and sign crews; lane closures and shoulder work; and sweeping, pothole patching, and utility work in live traffic. If you’re unsure whether your jobs require a TMA, we can help you match the unit to your agency’s specs.<\/p>\n\n\n\n
