The Tornado F4 Slope hydroexcavator from Petrofield Industries features a 13-cubic-yard mud tank and 2,100-gallon freshwater tank, with a boiler for hot water and a positive-displacement blower (4,000 to 6,300 cfm) to pull the spoils to the tank. The boom has a 342-degree rotation and a 26-foot reach. All of the critical components are housed in an insulated and heated aluminum van body. Because of the sloped floor design, operators do not hoist the tank to empty it, eliminating the dangers of overhead power lines and dumping on uneven ground. 877/340-8141; www.tornadotrucks.com.
