SELECTION GUIDE
There are many variables that determine how ef
fectively a vibratory pile driver will perform.
This graph
below is a guide, not a guarantee! V
ibratory drivers work at their best in granular (gravels and sands)
materials, where the amplitude in the pile can “
fl
uidise” 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
.

IZING GUIDE
For completness, the
fl
ow and pressure from the excavator to the EMV should be checked against the
speci
fi
cation sheets to con
fi
rm 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)
7 - 22 t excavator
EMV300 (requires 130 L/min, 280 bar)
12 - 35t excavator
EMV450 (requires 195 L/min, 270 bar)
25 - 45t excavator
EMV550 (requires 256 L/min, 280 bar)
30 - 55t excavator
