CFI's Driven Pile Academy: Hosted by the PDCA

HOW DOES A VIBRATORY PILE DRIVER WORK? As the eccentric pairs rotate, a Driving Force (CF & Weight) is created, aka Sinusoidal Vertical Force. Driving forces are in a vertical plane & all horizontal forces are cancelled.​ Output power is generated by spinning eccentric weights which develop a very large reactive force. The reactive force is proportional to the square of the rotational speed of the eccentrics.

Speed = Oil Flow (Engine RPM)​

Power = Pressure & Flow​
