TT Technologies offers new cutterhead configuration for static pipe bursting operations
TT Technologies recently introduced a new cutterhead configuration for its Grundoburst static pipe bursting system. The new configuration consists of three specially designed bladed, roller cutterheads in succession. The bladed roller cutting head configuration allows contractors to burst/split large diameter steel and ductile iron pipes when used with larger Grundoburst static bursting systems. The new special cutterhead design allows for a smoother host pipe cut and greater protection for the new pipe.
Pulled by a hydraulic bursting unit, the cutterhead’s special 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. The Grundoburst system features Patented QuickLock bursting rods that are linked together not threaded. This saves time, prevents twisting and extends the life of the cutterhead over threaded bursting rods.
