9-Yard Tandem Axle Configuration Available for Vactor HXX Prodigy Vacuum Excavator

STREATOR, ILL. (Jan. 11, 2008) – Vactor Manufacturing has announced the availability of a larger debris body for the HXX Prodigy Vacuum Excavator – an optional 9-yard debris tank mounted on a tandem axle chassis. The HXX Prodigy uses vacuum excavation methods to perform non-destructive digging for such applications as slot trenching, potholing, water valve box repair and locating of existing fiber optic lines, cables and other utilities. Vacuum excavation provides minimal ground disturbance and virtually eliminating the risk of damage to existing underground utility lines.

Lighter and more compact than the full-sized Vactor HXX HydroExcavator, the HXX Prodigy – both the standard 6-yard configuration and the optional 9-yard configuration – is specifically designed for mobile applications. The HXX Prodigy features an above-deck compressor system that does not need a holding tank to build pressure, which eliminates the wait time some units require for pressure to build up.

Air or water
Using hydro-excavation, the HXX Prodigy blasts away soil with jets of 10 to 20 gallons of water per minute, at rates from 1,500 to 2,500 psi, depending on the pump selection, pressure adjustment and nozzle tip configuration. For applications where dry digging is preferred, the HXX Prodigy also comes with an optional air excavation system, further adding to its versatility.

Both the HXX Prodigy and the HXX HydroExcavator facilitate digging in frozen ground, with optional on-board water heaters. The 400,000 BTU or 900,000 BTU water heaters available on the HXX Prodigy allow the operator to cut through frozen ground or heavy clay.
