Design features
The design of the Liebherr rotary drilling rigs especially focusses on fulfilling the high quality and
performance requirements. Above all, the rigs excel in their stability, precision and longevity.
Steel structure
All steel components were newly developed and especially designed for the high demands of
deep foundation applications. The large cross section allows for optimum force transmission
providing less material wear and a longer service life.
Undercarriage
The undercarriage was adopted from the proven Liebherr duty cycle crawler cranes and is de-
signed for toughest assignments.
Swing ring
Liebherr rotary drilling rigs are equipped with a triple-row roller bearing swing ring. The power-
ful swing mechanism features an eccentric flange to adjust the tooth flank clearance. Thus, the
clearance between upper- and undercarriage is reduced to a minimum which enhances the
stability during operation.
