GRB ‘Giken Reaction Base’ System

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 equipment required for the system is self-supported by holding existing installed piles with no risk of overturning. Temporary working platforms or detour roads are not required even in cases where there are unstable ground conditions, narrow access, a requirement to work over water, piling on a slope, or other restricted site conditions since the range of the work is minimised to just the width of the machinery.
