Customer: RTI (Resonance Technology International).
Normally in engineering we try to avoid resonance, these machines embraced it! The RD260, the 260kW Resonant Driver, could automatically tune & excite a pile at its resonant frequency. This highly sophisticated (but challenging) technique enabled piles to be driven into the ground efficiently, with minimal ground vibration.
