Powerful performance …
Where others reach their limits, the ADLER Heavy-Duty Auger Drive EHD truly excels!
That’s why the ADLER EHD Series features powerful radial piston motors, securely protected within a heavy-duty housing. Operation is possible via a single- or double-acting hydraulic circuit, enabling powerful and efficient drilling – even in hard ground, rock, or compacted material.
The auger drives can be mounted directly via the excavator’s quick coupler – or alternatively using bolt-on attachment. An integrated universal joint ensures perfectly vertical drilling – regardless of the carrier’s position.
Thanks to the generous pendulum travel of the EHD Series, smooth operation is possible without frequent adjustments to the excavator kinematics.
To protect the powerful drive and ensure long service life, a leakage oil line is required and comes as standard.
