The TERRA-EXTRACTOR X 400 is a cable burster (wire burster) which replaces old pipes from 1 1/2“ (ID 40 mm) up to 10“ (ID 250 mm). Lengths up to 150 m are possible. Old pipe from cast iron, steel, clayware or PE/PVC can be replaced. New HDPE pipes with outer diameters of 63 – 250 mm are pulled in. The TERRA-EXTRACTOR X 400 is operated via an electric remote control. No operator has to be in the pit or in the manhole during operation. An integrated electric control box changes the direction of the hydraulic cylinder.

The standard version of the TERRA-EXTRACTOR X 400 requires a working pit, which is only 1.70 m long and 1.00 m wide. In spite of this small working pit, the X 400 pulls the bursting tools and the new pipe into its front box and into the working pit, after the pipe renewal job has been finished. This is fast and efficient.

Compared to pipe renewal systems with rods, so called „rod bursters“, wire bursters have the advantage that the pipe renewal job can be done by one single operator without any interruption for dismantling the rods. Now operator has to be in the working pit during the bursting operation.

Another big advantage of a wire burster is the relatively small diameter of the pulling cables. This allows to burst ductile cast iron pipes ID 40 mm and ID 50 mm with pulling forces up to 40 tons.

The TERRA-EXTRACTOR X 400 operates at speeds up to 145 m/h. It is equipped with a pulling force of 400 kN (40 tons) which adapts itself automatically to the real working conditions. The TERRA-EXTRACTOR X 400 is powered by a supersilent Diesel power pack which has been designed exactly for this wire burster. As an option remote pressure control is available.

The TERRA-EXTRACTOR X 400 may be used in pits or “manhole-to-manhole”. If space is very limited, the TERRA-EXTRACTOR X 400 may be equipped with an optional special button frame. Then it can be used in pits which are only 1 m long and 1 m wide.
