    THE RENOVATOR

    GRUNDOBURST 1900G
    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
    • The GRUNDOBURST 1900G generates a max. pulling force of 427,136.91 lbf
      (190 t). This allows renewal of defective pipes from ND 9.84 to 31.50
    • The rods are 88.58 inches long and weigh 363.76 lbs each, the permissible bending radius is only 180.45 ft.

    PIPE RENEWAL ND 1,000 WITH GRUNDOBURST 1900G

    To the south-west of the Lower Saxony capital Hannover, at the centre of the city triangle Hannover – Hameln – Hildesheim, you can find a town called Springe, with 30,000 inhabitants and 12 urban districts.

    THE RAVAGES OF TIME

    Springe is a modern and lively little town with a well-developed infrastructure, even underground. The town’s public sewer network currently has a total length of about 550 km, of which approximately 310 km are allotted to the main canals and approx. 240 km to house connection service lines. The SES (Urban drainage utilities Springe), is an economically and organisationally independent municipal company that takes care of the operating, maintenance and servicing of this sewer network. This also means that SES bears great responsibility, since the oldest drainage systems in operation date back to the 19th century and their condition requires constant monitoring and attention.
