GRUNDOBURST 800 G
THE RENOVATOR
GRUNDOBURST 800G
THE BEST THING FOR PIPE RENEWAL
QUICKLOCK BURST RODS
- Quick locking couplings without thread (QuickLock), no lubrication required, therefore no time consuming screwing together required
- Quick rod insertion and removal
- The rods are connected faster than threaded rods
- Absolutely push and pull resistant
- Able to negotiate bends
- Integral production, therefore highly resistant to stress
- Robust, low-wear as clamping is not required
- No slipping back of the rods, due to direct force transmission
- Rod system with convenient rod accessories
- Longer service life than screwed rods
- QuickLock bursting rods are available from 35 mm diameter for pipes from ND 50
- Other rod diameters: 54 mm, 75 mm, 100 mm, 120 mm and 140 mm
PULLING FORCE MEASUREMENT GRUNDOLOG
- Monitoring and logging of pulling force imparted on new pipe during installation
- Performance categories: 150kN, 400kN, 1,250kN, 2,500kN
- Self-sufficient storage and live transfer of data possible
- Compact dimensions for small pits
- Can be applied from a pit in both directions
- Fast operating cycles and high output
- Rapid rod pushing through old pipe and during new pipe installation
- Quick to get started
- All machine models have remote control
- Low weight for easy transport
- Accessories specific to the procedure

RENEWAL OF AN ASBESTOS CEMENT SEWAGE PRESSURE LINE WITH GRUNDOBURST 800G
The Lower Rhine town of Korschenbroich lies between the metropolitan areas of Mönchengladbach, Krefeld, Neuss and Düsseldorf in the west of Germany. Despite the growing population, Korschenbroich with approximately 5.500 ha has never lost its countryside character in all of its districts. After all, approx. 68 % of the total area are used for agriculture, just under 22 % are residential, commercial and transport areas, the rest divided into recreational, forest and water areas.
