The GRUNDOBURST1250G  range. A new performance class begins, with a maximum pulling force of 1270 kN (127 t). The machine is either suitable for replacing old pipes from ND 150 to ND 600 over up to 300 m lengths or relining old pipes up to. approximately ≤ ND 1000. As higher pulling forces are required for penetrating the soil in greater installation depths the bursting rods are dimensioned accordingly with a length of 1.70 m and a weight of 85 kg. For models 1250G and upwards insertion and removal of the bursting rods is carried out with a lifting device.
