GRUNDOBURST 400 G

THE RENOVATOR

GRUNDOBURST 400G
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 constructionto 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 approx. 328 ft lengths (procedural)
  • Compact dimensions for small pits
  • Rapid work cycles and high performance
  • Fast rod pushing in the old pipe and fast pulling in of the new pipe
  • Light weight for simple transportation
  • Can be applied in both directions – from a single pit
  • Simple installation and rapid machine start
  • One-man operation with remote control
  • Accessories for specific methods
