GRUNDOBURST 1250 G

A new dimension of static pipe bursting

The Grundoburst 1250 G sets standards in trenchless pipe renewal. The machine develops a maximum pullback of 1270 kN (127 t). Due to this enormous pulling force, old pipes from ND 200 to ND 600 can be replaced for the first time with the pipe bursting technique.   The work flow resp. functioning is identical to the the little 'brothers' 400 G and 800 G.   The Grundoburst rig is aligned against the pit wall laterally and at the back with adjustable stabilisors, fixing the rig safely even with maximum pulling strain. The simple and proven patented QuickLock rod connection simplifies the assembly enormously. The bursting rods are lowered and taken out with a special lifting device.
