    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
