The Liebherr hydraulic tilt-rotator substantially increases the excavator's scope of application. Even in demanding conditions, this modular adapter carries out its work quickly and effectively. The horizontal tilt cylinder is optimally protected even at its maximum tilt angle and has no extruding parts. Its particular features such as infinite rotation in both directions, tilting at twice 50 degrees and the quick-change system make the hydraulic excavator a multifunctional unit. In combination with LIKUFIX, the entire tilt-rotator together with the working tools can be removed to accommodate other tools.
