The HV-64 all-season hydroexcavator from Transway Systems operates at less than 85 dBA. It has a 6,400 cfm and a 27-inch Hg high-vacuum blower with direct-drive transfer case. Water pressure is achieved with a hydraulically driven triplex pump, delivering 10 gpm at 6,000 psi. Water is supplied from a 1,200-gallon HDPE baffled water tank with 1/2-inch sides and 3/4-inch bottom floor. The 26-foot telescopic boom allows for operation in remote areas. Water is heated with a 525,000 Btu diesel-fired burner for all-weather operation. Components are enclosed in an insulated, heated, walk-in storage enclosure with diesel-fired heater, marine-grade plywood flooring and metal components that are powder coated prior to installation. 800/263-4508; www.transwaysystems.com.
