Hydraulic tilt-rotator

Tilt rotators have today become an essential part of civil engineering. Thanks to the flexible use
of the backhoe bucket, the unproductive repositioning of the hydraulic excavator during work
can be substantially reduced, and the productivity of the machine is increased.
Lieberr tilt rotators have a slewing angle of 2 x 50º and can rotate infinitely through 360º. The
integrated rotating cylinder itself, which is protected and located horizontally, has no projecting
parts even at maximum rotating angle, which could otherwise be damaged when working in
confined spaces. This ensures that servicing costs are kept low, and makes Liebherr tilt rotators
the ideal tool for working in lining operations or when close to building structures. In conjunction
with the ergonomic Liebherr proportional control system, the tilt rotator can be put to use rapidly,
with fine sensitivity, and with maximum precision, which helps achieve high productivity for the
hydraulic excavator.
The preparation of complex excavation contours and the exposing of existing structural
elements such as drain shafts, pipes, etc. can be carried out extremely rapidly with Liebherr
tilt rotators. Tedious and sometime dangerous shaft excavation by hand can be reduced to a
minimum, and personnel can move on to the next tasks to be dealt with.
It is recommended that Liebherr tilt rotators be fitted on the upper side with the Likufix quick
coupling system from Liebherr. In this way, the tilt rotator is only attached when it is actually
needed, which reduces fuel consumption, increases the service life of the tilt rotator, and allows
for the maximum load capacity of the hydraulic excavator to be fully exploited during hoisting
operations. In traditional earthmoving situations, taking off the tilt rotator allows for the largest
possible backhoe bucket to be fitted, in order to achieve high handling performance with low
fuel consumption.
Together with Liebherr wheel and crawler excavators, Liebherr tilt rotators attain maximum
productivity, reliability, and safety on the construction site.

Clamshells

Next to the backhoe bucket, the clamshell is one of the most important digging tools in the
utility business. The clamshell selection is based on the ground condition, the specific mate­rial weight and the required production performance. The selection of the entire clamshell
attachment is significant in order to determine the required digging depth.
