The robust universal machine for a wide variety of applications:
•Kelly drilling
•Auger drilling
•Full displacement drilling
•Double rotary drilling
The solid undercarriage offers excellent stability and low ground bearing pressure.
The uppercarriage with its small swing radius enables operation in restricted space.
Parallel kinematics with a large working area allow to fold back the leader.
The rigid leader absorbs high torque and is fitted with a rope crowd system for high pull forces.
All winches are mounted on the leader, which provides a direct view of the main winch from the operator’s cab.
The rotary drive of the BAT series combines exceptional torque with optimum operating comfort.
The powerful Liebherr diesel engine is low in emission and economical through SCR technology.
The Litronic control with assistance systems supports the operator:
•Cruise Control for the drilling process
•Joystick control for all machine functions
•Automatic shake-off function for working tools
•Leader inclination memory etc.
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.
Liebherr Kelly bars feature strongly overlapping elements resulting in less wear.
Precise and robust Liebherr casings and drilling tools provide excellent drilling performance.
