Hydro Excavator Truck
The RAMVAC HX-15 is the “Big Daddy” of the RAMVAC family, however, you do not have to compromise for that size either. We still feature a footprint 36” shorter and a payload capacity 2500 lbs greater than our competitors. This tridem axle configuration unit offers a 15-cubic-yard debris body, a boom reach of 21 to 26 feet with a 320° working radius.
The 8″ vacuum system for these units feature a 4400 CFM and 18″ blower capacity, with the ability to do 5400 CFM and 28″ blower, well as cyclone separation, a vacuum enhancer, directional discharge, hydrostatic blower drives, and a 10-micron final filter. For the water system, this hydro-vac truck features a 1,300-gallon water capacity, a 10 GPM @ 2500 PSI pump, 400,000 BTU water heater, all in an 80,000 BTU heated enclosure.
The HX-15 also boasts compact footprints, NEMA rated electrical systems, debris blow-off systems, and fully hydraulic power trains for superior reliability. For customers looking to dig with air, you have the option to add a 185 CFM @ 150 PSI air compressor to your unit.
