Hydraulic tilt-rotator
Liebherr-Proportional-Control for intuitive control of working tools Protected cylinders, no extruding parts
Applications
• Challenging profiling
• Pipeline
• Garden- and landscaping work
• Complex digging work
Features
• 360° infinite rotation
• best possible protection for tilt
and swing drive
• Tiltable both sides by 50°
• Rugged design
Benefits
• Increase of the productive worktime (accurate
excavation, precise backfilling and quick profiling)
• Expanded utilization of the excavator
• Highly accurate due to easy handling
• Significant time savings since excavator needs
repositioning less often
• Everything from one source
• Liebherr excavator controls include tilt-rotator function
• Backhoe bucket can also be used as a face shovel
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.
