GRUNDOBURST 2500G

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.
  • 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
