Press-in machines utilise reaction force from installed piles integrated with the Earth and carry out piling work while self-moving on top of installed piles. With further development based on the principle of “Footprint Free Installation System”, “GRB System” was developed as a press-in system which carries out all piling procedures such as pile transportation, pile pitching and press-in work on top of installed piles.
All system equipment are self-supported by holding existing installed piles with no risk of overturning. Temporary working platforms or detour roads are not required even at unstable ground condition, in narrow location, on water, on slope, and under other restricted site conditions since influence range of work is minimised to just the width of those machinery.
