Excavator Mounted Vibrator
There are many variables that determine how effectively a vibratory pile driver will perform. This graph is a guide, not a guarantee! Vibratory drivers work at their best in granular (gravels and sands) materials, where the amplitude in the pile can “fluidise” the ground and allow the pile to advance as the ground rearranges itself. They will still function in cohesive materials (clays), but piles will not penetrate as far.
Excavator sizing guide. For completness, the flow and pressure from the excavator to the EMV should be checked against the specification sheets to confirm adequate hydraulic power. As a guide the EMVs typically suit the following base machine sizes:
EMV70 (requires 30 L/min, 240 bar) ~ 5.5 - 17 t excavator
EMV220 (requires 90 L/min, 280 bar ~ 07 - 22 t excavator
EMV300 (requires 130 L/min, 280 bar) ~ 12 - 35 t excavator
EMV450 (requires 195 L/min, 270 bar) ~ 25 - 45 t excavator
EMV550 (requires 256 L/min, 280 bar) ~ 30 - 55 t excavator
