TT-Group presents lots of new items at NODIG 2011

At International NO DIG 2011 which will be held from May 2 - 5 in Berlin conjunction with WASSER BERLIN, Tracto-Technik (TT-Group) are presenting a variety of innovative machines and equipment for the trenchless installation and replacement of pipes.

Beside the proven GRUNDODRILL HDD systems for installing pipes up to Ø 700 mm and the GRUNDOBURST pipe bursting machines for replacing pipes up to Ø 1000 mm TT presents various new developments.

Featured TT innovations at NODIG / WASSER BERLIN 2011 include the new GRUNDOMAT N generation which is a milestone in the 40 year history of the GRUNDOMAT soil displacement hammers. A strong characteristic of the new GRUNDOMAT N is the crowned head.  It is the best at adapting to the "unknown" in the ground and has a high penetration force. The adjustment to the various stroke frequencies in alternating soils provides an even calmer, stable running performance.

The longitudinal manoeuvrability (two stroke principle) of the
crowned head is clearly visible.


Further innovations are the GRUNDOMAT Liner System for the trenchless renewal of house connections with flexible pipes, the BURSTFORM forming device which allows for the renewal of deep lying service lines through manholes up to OD 292 and the GRUNDOPULL device for exchanging lead pipes.

Visitors of NODIG / WASSER BERLIN 2011 can witness all these innovations and more at the TRACTO-TECHNIK (TT-Group) Stand No. 204 in Hall 1.2 from May 2 -5, 2011.
