17 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.

Applications Benefits • Challenging profiling • Increase of the productive worktime (accurate • Pipeline excavation, precise backfilling and quick profiling) • Garden- and landscaping work • Expanded utilization of the excavator • Complex digging work • Highly accurate due to easy handling Features • Significant time savings since excavator needs • 360° infinite rotation repositioning less often • best possible protection for tilt • Everything from one source and swing drive • Liebherr excavator controls include tilt-rotator function • Tiltable both sides by 50° • Backhoe bucket can also be used as a face shovel • Rugged design
