The midsized, truck-mounted X-6 hydroexcavator from Hi-Vac Corp. has a 6-cubic-yard debris tank and carries 570 gallons of freshwater with an optional 1,000-gallon capacity. 

“There are a lot of hydroexcavators out there that are either very, very big or very, very small trailer-mounted vacuum systems with small capacities,” says Dan Coley, president, Hi-Vac. “There aren’t a lot of midsized hydroexcavation machines, and that’s what the X-6 is. It’s a midsized unit.” 

The adjustable triplex water pump delivers up to 3,000 psi and is set independently of the blower speed. The vacuum system ranges from 2,600 cfm at 27 inches Hg to 3,400 cfm at 16 inches Hg. 

“The advantages you get with a high-vacuum system, 27 inches, is when you’re vacuuming heavy sludges, slurries or liquids or you’re vacuuming over a long distance, that high vacuum and very good cfm airflow allows you to vacuum in more difficult situations,” he says. “It allows you to load faster. Sometimes when you’re hydroexcavating, the material you’re hydroexcavating is very, very thick and heavy. That’s when you need to rely on your inches of mercury or vacuum to help load.” 

The hydroexcavator, with 6-inch hose, can expose any type or size of underground utility and is especially suited for residential areas with limited work space.

“The volume of material you’re vacuuming does not require a larger debris box,” Coley says. “If you’re potholing or daylighting, it’s appropriately sized. The 6-cubic-yard debris body is all you’re going to need.” 

The X-6 can be mounted on any brand of appropriately sized single- or tandem-axle truck. The water pump and vacuum system are driven by a split-shaft transfer case. There is no auxiliary engine. 

“The X-6 is primarily for utility excavations where the depth and distance are very close to the truck and the volume of material you’re digging does not exceed the 6-cubic-yard debris body that you have on the rig,” he says.

Options include a 320-degree, top-mounted rotating boom and water heater for cold weather and hard soil excavation. The water pump and blower can be shrouded. 800/752-2400; www.x-vac.com.
