GRUNDOBURST 400 S
THE RENOVATOR
GRUNDOBURST 400S
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
- Stable and job-site specific construction to withstand the highest of loads and strain
- Long service life and low maintenance effort
- Ergonomic operation and high level of work safety
- CE-certified
TECHNICAL SPECIFICATIONS
- For pressure and sewer lines ND 1.97 – 9.84 inches up to app. 328 ft length (procedural) for installation in manholes ≥ ND 1000 and in small pits
- Pulling rig length only 23.62 inches
- Effective rod length in the manhole: 18.05 inches
- Relatively simple operation in the manhole
- No excavation when working from manhole to manhole
- All-round working safety
