Steel construction
The hydraulic crawler cranes’ uppercarriage with its robust and torsion-re-
sistant box design is mounted on a large undercarriage featuring wide track
and long crawlers. This results in good ground pressure characteristics and
stability.
The external, large dimension teeth of the Liebherr swing drive guar-
antee optimum absorption of the high torque combined with mini-
mum wear. Roller bearings in the swing drive ensure a superior,
low-fi t connection between upper and undercarriage. For
special applications, e.g. rotary drilling or dragline applica-
tion, an additional increase in torque is achieved through
the installation of a second and/or third swing drive.
