The Tornado F4 Slope hydroexcavator from Petrofield Industries holds 13 cubic yards of mud and more than 2,100 gallons of freshwater. It has a water tank from which you excavate, a mud tank to which the excavated spoils are held, a water pump, a boiler to heat the water, and a positive displacement vacuum blower (4,000 to 6,300 cfm) to pull the spoils to the tank via a boom. 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
