The HXX Prodigy vacuum excavator from Vactor Manufacturing is mounted on a 33,000-pound gross vehicle weight Class 7 truck chassis. It has a user-friendly control system identical to the controls used on the full-sized HXX HydroExcavator and a standard extendable boom with 320-degree rotation that provides full coverage of the working area. An optional telescopic boom is also available. It hydroexcavates soil with jets of up to 10 gpm, at rates from 1,500 to 2,500 psi. It has a 16-inch Hg, 3,200 cfm positive displacement blower with a filtration system that can handle both air (185 cfm at 150 psi) and water (10 gpm at 2,500 psi) without a bag house. The variable-pressure triplex pump allows the operator to adjust water pressure with the push of a button. An air excavation system is available for applications where dry digging is preferred. It is available with a PD system. The blower and 6-inch hose provide increased performance. 800/627-3171; www.vactor.com.
