The TERRA-HYDROCRACK is a hydraulic cracking system to renew gas pipes, water pipes or sewerage lines. Due to its high thrust and pullback forces of 600 kN (60 tons) it cracks or cuts PE pipes, steel pipes, cast iron pipes or even ductile cast iron pipes from ø 50 mm to up to 350 mm. New HDPE pipes up to OD 355 mm may be pulled in. In a first step, the highly sophisticated rods are pushed through the old pipe. As soon as the rods arrive at the target pit, a 3-wing bursting rod, an expander cone and the new PE pipe are assembled to the rod. Now the TERRA-HYDROCRACK pulls the rods back, cuts the old pipe into 3 slices, enlarges the bore channel and pulls in the new PE pipe – all simultaneously. It is even possible to push the rods into a second pipe section, whilst the new pipe is pulled in into the first pipe section. This saves time.

The main cylinder with hollow piston rod can be moved inside of the trench box from the front to the rear. This allows to pull the bursting tools and the new HDPE pipe completely into TERRA-HYDROCRACK after the pull-back operation. Therefore it is not necessary to move the whole machine. It is possible to work in both directions of the working pit without turning the machine. Whilst the HDPE pipe is pulled into the first section, the rods may be pushed simultaneously into the second old pipe section.

The Automatic Foot Control AFC allows to operate the TERRA-HYDROCRACK with a foot pedal. As long as the foot pedal is pressed down, the main cylinder works. The foot pedal is mobile and may be placed anywhere around the working pit.

The operator may sit comfortable in the operators seat of the TERRA-HYDROCRACK HC 600 C+. This „Cracking with Comfort“ is easy, fast and comfortable. The operator sits well protected within the trench box. This Comfort Version requires a 3 m long and 1 m wide working pit. The rods can be taken easily from the rod magazine underneath the operators seat. This allows easy handling during assembly and disassembly.

The TERRA-HYDROCRACK is also available as a short version.

- HONDA petrol engine GX 670 with 24 HP (18 kW)
- electric starter
- engine control management which switches the engine off in case of low engine oil.
- battery 12 Volt with large capacity of 45 Ah
- hydraulic tank pack with return flow filter
- reliable oil cooler with large cooling capacity
- even tropical or desert operation possible
- hydraulic twin pump (fixed displacement pumps)

Additionally time saving is the PERKINS Diesel Power Pack which operates supersilent. Due to its high oil volume of 200 ltr/min working speeds up to 225 m/h are possible. This makes the TERRA-HYDROCRACK HC 600 C+ to one of the fastest and most productive pipe renewal systems worldwide. The rods are made from special steel. They follow old pipes with curve radiuses of 17 m, which can be burst even under full load.

- for cracking or cutting of old pipes from cast iron, ductile cast iron, steel, clayware or concrete
- cuts also repair collars
- short single units for easy disassembly after having finished the pipe pulling procedure.
