3 Perforance Liebherr crawler excaators feature state-of-the-art technolog and high-qualit workanship. The ost iportant coponents of the drie sste are all produced b Liebherr and are perfectl coordinated with one another. The engine generation, as further deeloped for the C-series, assures an effectie power delier, a high degree of efficienc, long life expectanc and coplies with the eission standard Stage IIIA / Tier 3. Reliabilit High deand for perforance and qualit is consequentl conerted into landark solutions to achiee the highest leel of dependabilit and reliabilit. Liebherr has oer 50 ears experience in the production of hdraulic excaators and has an unparalleled copetence in design and know-how. Cofort In the operator s station, the operator can look forward to a cofortable workstation that is designed according to the ost up-to-date ergonoicall know-how. The standard cliate control proides a pleasant working enironent in all weather conditions. Liebherr crawler excaators are particularl serice-friendl: Maintenance work is sipl and quickl accoplished due to well accessible serice points. Econo Liebherr crawler excaators stand for axiu productiit. The sensitie excaator controls assure optial efficienc in the interaction of excaator hdraulics and electronics. A wide selection of attachents and buckets with arious diensions proide the correct choice for eer application. R 944 C Litronic 3
