This video shows RTI's Resonant Pile Driver (Model RD 140) in action driving an HP 360 x 132 pile. Please note the glass of juice placed 300 mm from the pile in the video. The glass shows that there was virtually no ground disturbance around the pile while being driven by the RD 140. The RD 140 drove the first 18 m in 4-5 minutes and the second 13 m in 3-4 minutes. The 3500 kg (7800 lbs) drop hammer required between 60 and 80 minutes to drive the full pile.
