What is the Hendrickson HAULMAAX EX?
HAULMAAX EX is Hendrickson’s rear rubber suspension with a walking-beam layout. Its progressive spring arrangement is intended for vocational work such as dump, mixer and refuse applications. Hendrickson documents production changes within the EX family, making the build date relevant when identifying parts.
What matters in a comparison
For HAULMAAX EX, collect the suspension identification and truck build date before comparing service proposals. Ask whether quoted parts correspond to the installed version. Evaluate empty and loaded work separately when discussing ride preferences with the supplier. Capacity, body height and application approval belong in the same assessment; a favourable ride description is not evidence that a different body is approved.
Questions to take to the supplier
- Which production version is installed?
- Do proposed parts match the identification and build date?
- What loaded and empty duty should the assessment cover?
