The Terra-Vex all-season hydroexcavator from Transway Systems has a Robuschi RB-DV145 6,400 cfm blower with OMSI transfer case and insulated acoustical enclosure with walk-in storage. Water pressure is achieved with a hydraulically driven Pratissoli KT20 water pump, delivering 10 gpm at 6,000 psi. The 3,000-gallon debris tank has a hydraulically operated hoist, and door locks with full-open door. The 1,200-gallon HDPE water tank supplies a 420,000 Btu diesel-fired burner permitting operation in subzero temperatures. The water pump and water tank compartments are heated by a diesel-fired heater and 12-volt engine coolant heater. The 26-foot hydraulically operated 8-inch suction boom is equipped with joystick control and wireless remote control. All parts are painted/powder-coated off the unit, and it includes marine-grade plywood floor enclosure, three-camera back-up system and digital water level display.
