This hydraulic machine is capable of performing vibration-free installation and extraction of sheet piles. It operates by gripping previously driven piles to provide reaction force for pressing in the next pile.
The Silent Piler works on top of the reaction piles and self-travels to the next position as illustrated below. This technique allows sheet pile driving at sites not accessible for conventional piling techniques. Only a relatively light-weight service crane is needed to pitch the sheet piles.
