GRB System™

Temporary Work-Free Construction System

GRB System™ (GIKEN Reaction Base System)

Press-in machines utilise reaction force from installed piles integrated with the earth and carry out piling work while moving along the installed piles. With further development based on the principle of “Temporary Work-Free Construction System”, “GRB SystemTM” 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.

Standard Components of the GRB System™

The GRB SystemTM consists of SILENT PILERTM in the front, Power Unit as a power source, CLAMP CRANETM to pitch piles and PILE RUNNERTM to convey piles from storage yard.
