The G Series Grundoburst static pipe bursting system from TT Technologies can burst anything from clay and concrete to ductile iron and steel, and can pull in a variety of replacement pipe including PVC, DIP, ABS, cast iron, fusion-welded HDPE and VCP jacking pipe.

The QuickLock bursting rods are linked together instead of threaded to prevent twisting. This saves time and extends the life of the cutter head while increasing safety.

“You just drop them in and they connect automatically,” says TT Technologies President Chris Brahler. “There’s no threading. It’s a much more certain connection.

“You don’t have to shut the machine down when you’re pushing out the stem or pulling back during the bursting process,” he says. “It’s just a continuous feed or a continuous disconnect. Operators don’t have to worry about trying to break apart a threaded rod that’s been twisted.”

Pulled by a hydraulic bursting unit, the bladed cutting wheel splits the host pipe instead of ripping or tearing it like single-fin-type static systems. An attached expander spreads and displaces the split pipe into the surrounding soil while simultaneously pulling in the new pipe.

Eight models are available for bursting 2- through 54-inch pipe and larger. Pullback force ranges from 90,000 to 575,000 pounds.

“We have such an array of machines from small to medium to large, and the contractors can also do sewer pipe bursting with it,” Brahler says. “Generally, a contractor can standardize in one machine, and with a wide range of accessories can retrofit the system without buying another machine.” 800/533-2078; www.tttechnologies.com.
