    • GRUNDOPIT – PS40

    SPEEDY HIGH-FLYER

    The GRUNDOPIT PS40 was specially developed for a quicker, near-surface production of house connections. The extremely compact Mini-HDD is suitable for a particularly small pit, which fits into footpaths with its width of only 1 metre. That is why the GRUNDOPIT PS40 is ideal for the production of FTTH-connections directly from the footpath, under which the public fibre optics infrastructure normally runs. Due to the low distance between the bore axis and the bottom of the starting pit, the bores can be started directly above the existing underground network from a flat starting pit.

    Even house connections for water and electricity can be installed with the GRUNDOPIT PS40 uncomplicated, within the available infrastructure, up to the building. A coring unit can be applied to create a core bore in manhole or cellar walls and allow a direct installation without a head access hole. Thrust and pulling forces up to 4t enable the installation of pipes up to Ø 100 mm over max. 50 m lengths, even through challenging soils.

    CONTROL PANEL

    Well laid-out, swivelling control panel for comfortable handling and control of the bore rig from any position.

    UNFOLDING CLAMP

    Large backreamers up to max. OD 150 mm can be pulled directly into the rig – no extension frame required.

    01. Drill rod effective length 500 mm with a rig length of only 1.174 mm – allows quick and productive work even in extremely tight working spaces
    02. Hydraulic Clamping Device: safer, comfortable, quick drill rod exchange  
    03. Thrust via rack and pinion drive, rigid construction, low maintenance and wear
    04. Small distance between bore axis and bottom edge of machine. Start from very flat pits, directly above the available infrastructure
    05. Working platform with safe and clean stand, earthing the machine operator
    06. Removable rotary drive with lifting unit, especially compact construction and ergonomic drill rod handling
    07. Fold-out control panel, compact transport position, quick set-up
    08. Optional: Mechanical or hydraulic tensioning inside the pit, short-set-up times, ergonomic work and high stability

    HOME-FRIENDLY
    SMALL, FAST, FLEXIBLE

    The extremely compact Mini-HDD is suitable for a particularly small pit, which fits into footpaths with its width of only 1 meter.

    ROTARY DRIVE WITH QUICK ROD CONNECTOR

    Simple and quick connection of the rod to the rotational drive, without screwed fittings enable immediate paddle function.

    HYDRAULIC PIT-START FRAME

    For short set-up times, ergonomic work and high stability
