Undercarriage
The robust universal machine for a wide variety of applications:
• Kelly drilling
• Auger drilling
The rigid leader absorbs high torque and is fitted with a
rope crowd system for high pull forces.
• Full displacement drilling
• Double rotary drilling
All winches are mounted on the leader, which provides
a direct view of the main winch from the operator‘s cab.
The solid undercarriage offers excellent stability and low
ground bearing pressure.
The rotary drive of the BAT series combines exceptional
torque with optimum operating comfort.
The uppercarriage with its small swing radius enables
operation in restricted space.
The powerful Liebherr diesel engine is low in emission and
economical through SCR technology.
Parallel kinematics with a large working area allow to fold
the leader back and, as an option, forward.

Liebherr Kelly bars feature strongly overlapping elements
resulting in less wear.
Precise and robust Liebherr casings and drilling tools
provide excellent drilling performance.
Sophisticated solutions provide safe operation and maintenance of the machine.
• Cab design for optimum visibility
• Acoustic and optic warning
• Walkways on the uppercarriage
• Safety rails on top of the uppercarriage
• Rear and side view cameras etc.
