Large-diameter steel cutting head for static bursting
This specially-designed, bladed, roller cutting head allows contractors to burst/split steel pipes up to 32 inches in diameter when used with larger Grundoburst static bursting systems.
The Grundoburst static pipe bursting system utilizes the specially-designed, bladed cutter head to make bursting ductile iron and steel pipe possible. Pulled by a hydraulic bursting unit, the cutter head’s cutting wheels split the host pipe. An attached expander spreads and displaces the split pipe into the surrounding soil while simultaneously pulling in the new pipe.
QuickLock bursting rods are linked together, not threaded, which saves time, prevents twisting and extends the life of the cutter head over threaded bursting rods.
Models range in pullback force from 60,000 to 650,000 pounds. Grundoburst models are designed for bursting 4-inch through 48-inch diameter pipe and larger. According to TT Technologies, of the eight models available, the new 32-inch cutter head is the largest cutter head of its kind in the world.
