House connection renewed with cable burster X 300 C
A house connection for fresh water had to be renewed in the Swiss village Balsthal by pipe bursting. The contractor Eggenschwiler from Balsthal used the cable burster TERRA-EXTRACTOR X 300 C successful for this pipe laying project. The old pipe from cast iron with an inner diameter of 40 mm (1.5“) was replaced by a PE protection pipe with OD 72 mm (2.8“). The old pipe had a leakage 10 years ago, which had been repaired by a repair collar from ductile cast iron. The old pipe was burst with a static 3-wing cutter. This cutter pushed the repair collar out of the ground. This bursting project could be finished within half a working day.
The TERRA-EXTRACTOR X 300 C is an innovative cable burster for replacement of old pipes made from cast iron, steel, clay ware or PE/PVC. With this machine you can burst old pipes with Ø 34 - 220 mm (1.5“ – 8.5“) and pull in new HDPE pipes with Ø 63 – 180 mm (2.5” – 7”) in lengths up to 120 m (400 ft). With a maximum pulling force of 300 kN (30 tonnes / 66‘000 lb/33 US tons) it is a strong but compact machine.
The Cable Burster X 300 C can operate on smallest areas of L x W = 0.42 m x 0.60 m (16.5” x 22.6”).
The X 300 C can be installed in manholes of Ø 800 mm (32") and dismounted it can be lifted through manhole entries of Ø 620 mm (25").
Special cables Ø 22 mm (0.9”) and Ø 14 mm (0.6”) allow the replacement of smallest pipes.

Pic. 5: The protection pipe reaches the machine pit. The protection pipe is pulled into the machine pit. Then the product pipe is pushed into the protection pipe.
Pic. 6: The repair collar from ductile cast iron could not be cut. It was pushed of the ground.
