How to Maintain Blade TMAs for Long-Term Highway Use
A Blade attenuator can serve for years if the blades, hydraulics, and lighting get regular attention. A practical maintenance rhythm keeps it deployment-ready.
The Blade TMA earns its keep through simplicity: 12 crumpling blades absorb an impact and are replaced afterward. Long service life comes down to keeping the deployment system healthy and the blades in their designed condition.
A maintenance rhythm that works
- Pre-shift: confirm deployment, check warning lamps and the arrow board, look for obvious fluid leaks.
- Monthly: inspect blades and mounting hardware, grease pivot points, check hose condition.
- Scheduled service: full hydraulic inspection, seal check, and re-certification as required.
Texas conditions, adjusted intervals
Heat and road dust shorten the interval between meaningful checks. Fluids degrade faster in high temperatures and grit finds its way into moving parts. Treat the manufacturer schedule as a floor and tighten it for a unit that works summer jobs across North Texas.
After any impact, replace the affected blades and have the frame inspected before returning the unit to service. Crumpled blades do not absorb energy the way fresh ones do.
