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 constructionto withstand the highest of loads and strain
  • Long service life and lowmaintenance 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
