The Vactor HXX HydroExcavator provides up to seven hours of continuous operation with onboard water. The standard variable-flow water systems allow lower water flow, resulting in less operator fatigue and a cleaner, more precise digging process. The systems also allow up to 25 gpm for those projects requiring higher water-flow capabilities. DigRight Technology allows selection of the maximum desired working water pressure based on vacuum excavation best practices. This will limit the water pump from exceeding site, industry or customer maximum pressures to ensure a safe and nondestructive method of excavation. It also reduces wear and tear on the water system, extending product life. Its boom turret provides increased vertical range of motion for improved operator performance and productivity, enabling the operator to complete most applications with only one dig tube. 800/627-3171; www.vactor.com.
