What is the Hendrickson VANTRAAX?
VANTRAAX is Hendrickson’s air-slider system for dry-van and refrigerated trailers. The manufacturer describes it as combining INTRAAX running gear with a K2 slider box. It should therefore be evaluated as a complete slider and suspension assembly, rather than simply another name for INTRAAX.
What matters in a comparison
On a VANTRAAX trailer, identify the slider assembly as well as its axles and brakes. Review maintenance history for the whole running-gear system and ask whether any replacement components changed the original specification. Compare trailer loading needs with the available approved positions and capacities. This profile does not provide slider-operation instructions; use the trailer and suspension manufacturer’s own material.
Questions to take to the supplier
- Which slider and running-gear configuration is fitted?
- Are service and replacement records available?
- What loading requirements must the complete trailer meet?
