From Spec to Service: How We Get a TMA Truck Ready

A work-ready attenuator truck starts as a chassis and a spec sheet. Here is how Heartland specs, sources, upfits, and services a unit until it is MASH compliant and ready for the lane.

Every truck that leaves our shop follows the same path, whether it is a stock unit or a custom order for a striping contractor. The goal is the same each time: a unit that protects the crew, carries the right boards, and passes inspection without drama.

Spec and chassis

We start with the work the truck will do. A freeway crew running at 50 mph needs a TL-3 attenuator and a chassis rated at or above roughly 26,000 lb GVWR to prevent underride. A low-speed municipal crew may only need TL-2. Once the requirements are set, we source and match the chassis, ballast, and attenuator before any wrenches come out.

Upfit and mounting

Our North Texas shop handles the upfit. Attenuator mounts, hydraulics, wiring, and the board setup all get installed and tested here. We fit both the non-blade Scorpion and the 12-blade crumpling Blade units, then run the deployment cycle to confirm it drops in about 20 seconds and stows for transport.

• Attenuator mounted and cycle-tested
• Arrow or message board wired and aimed
• Lighting, ballast, and GVWR verified
• FHWA eligibility documentation matched to the unit

Final check and handoff

Before a truck leaves the shop, it goes through a final inspection against the MASH-2016 paperwork so the buyer or renter has clean documentation from day one. Working out of North Texas, we keep units moving and turnaround short.
