The Standard HX-12 is the cornerstone of the RAMVAC lineup, delivering the performance, efficiency, and reliability contractors depend on every day. Engineered with a footprint that is 36 inches shorter and a payload capacity that exceeds competitors by 2,500 pounds, the HX-12 sets a clear benchmark for productivity in the hydro excavation industry. Its compact design enhances maneuverability without sacrificing power or capacity—making it ideal for demanding job sites where space and performance both matter.
And just when it seemed the HX-12 couldn’t be improved, it evolved even further. The introduction of the HX-12 with a quint axle configuration takes capability to the next level. Featuring six total axles, this model retains all the trusted performance of the standard HX-12 while offering increased weight distribution, improved stability, and greater hauling efficiency—giving operators even more confidence on the road and on the job.
Why a Quint Axle?
Additional axles mean greater payload capacity. Yes, the HX-12 already has a larger payload capacity than our competitors, but with a quint axle, the payload is the largest legal payload in the industry at over 27,000 pounds.
A quint axle also means that the truck can more easily comply with federal bridge laws. Six total axles (one in front and five in the rear), compared with the normal four (one in front and three in the rear), allows for more weight distribution, meaning a higher legal weight limit. When traveling with a high payload, additional axles can make a significant difference. Depending on the state, you would have to pay a penalty or even offload some of the weight you are carrying if your truck doesn’t comply with the law. A quint axle configuration can help operators better meet applicable weight regulations and reduce the risk of overweight penalties.
