HyrdroBurst 100 XT pipe bursting system exerts 99 tons of pulling force. It weighs 3,200 pounds, is 39 inches high and 30 inches wide. The machine can replace pipes up to 16 inches in diameter, says HammerHead Trenchless Equipment. The water-cooled PP4500 hydraulic powerpack is powered by a 72.7-horsepower Kubota engine and pumps hydraulic fluid at up to 43.5 gpm and 4,500 psi. In 50-ton mode the unit directs all hydraulic fluid to just two of the cylinders, which then can move twice as fast as in 100-ton mode, the company says.
The machines pulls 2.5-inch rods, and the spinner assembly is rated to 250 lb.-ft.
