5 Adanced techniques heighten perforance In its design offices, Liebherr cobines the technological knowhow of each area to create consistent and optiised integrated sstes. Liebherr s electronics, positie control hdraulics, and een the trael otors are designed fro the start to be interconnected and generate optiu operating power with fast and fluid oeents. Positie Control hdraulic sste Two working pups for axiu excaation, trael or swing efficienc, proide power to the coponents inoled. Thanks to the positie control sste, the cobined oeents are optiised for each different work operation, whether this be leelling, extraction, loading or lifting, with or without trael. Particularl fast work ccles The work ccles of the R 920 are er fast thanks to the large sized transission coponents. For exaple, the uppercarriage s swing drie can quickl reach its axiu speed with a high swing torque. Operating pressure Maxiu digging and break-out forces can be reached thanks to the leel of hdraulic pressure, without appling teporar oerpressure. Maxiu forces are therefore guaranteed continuousl during the whole working phase to achiee a high leel of production. To further iproe the achine perforances, the equipent speed is optiized through an integrated regeneration circuit. Engine Cuins engine Stage IIIA / Tier 3 Designed specificall for construction applications Autoatic fuel-saing idling sste Wastegate turbo for enhanced perforances at low speed and reduced consuption Undercarriage Robust design for greater resistance and a better distribution of forces Eas and safe transport thanks to integrated lashing ees Productiit and flexibilit Higher digging and break-out forces for increase in productiit New optional pads aailable in 700 and 800 for ore ersatilit New swing otor for higher swing torque and speed R 920 Litronic 5

7 Less fuel Associated with the latest deelopents in technolog and hdraulics, the tried-and-tested 6-clinder Cuins engine consues little fuel, both in ters of hours of operation and in ters of tons of aterial oed. Electronic power control This control sste allows the engine power to be effectiel and optiall conerted, fro an energetic point of iew, into hdraulic power. This results in greater forces, a faster working speed and a lower fuel consuption. Increased productiit Clearl enhanced perforances and low cosuption, cobined with the largest fuel tank on the arket, all in a cofortable and ergonoic work enironent, lead to significant increases in productiit in all operating configurations. Liebherr Lubricants Liebherr offers ou a full range of lubricants and coolants for our Liebherr achines Being designed especiall for our Liebherr achines, Liebherr lubricants contribute significantl to lowering our operating and aintenance costs Liebherr tools Wide range of tools suitable for eer tpe of application Tools designed for axiu productiit and durabilit Shape of buckets designed to assist the filling and stabilit of bulk aterials during the transport stages Modular quick-change sste ade b Liebherr The suitable digging tool for eer application The optional quick-change sste pas for itself er quickl and our achine becoes a ultifunctional tool carrier R 920 Litronic 7

A top-of-the-range anti-corrosion protection A pre-assebl painting process guarantees that all painted parts are full coated. The use of a high-qualit paint proides resistance against extree external conditions. Perfect atch The indiidual coponents of the power train such as the diesel engine, gears, swing drie, working pups and hdraulic clinders are specificall diensioned to work together. This eans that the are all copatible with each other in a global sste, guaranteeing higher reliabilit and a longer serice life. Autoatic control of functionalit The operator can entirel focus on his job, because the integrated on-board electronic continuousl perfors a coparison with pre-deterined target data.

11 A first class work space In this cab, the operator benefits fro a high-qualit echanical suspension seat, an enlarged space and a er cofortable working enironent. Depending on the operator s needs, the Cofort seat can be selected as an option. This seat offers axiu cofort thanks to its air suspension, seeral horizontal and ertical settings, as well as its adjustable pneuatic lubar support. It is especiall designed to eet the ost challenging cofort requireents of operators, in all working situations. Uncoproised isibilit The er large glazed surface area and inial area of fraes guarantee optial isibilit fro the operator s platfor, as well as a wide eergenc exit fro the rear window for the operator s safet and peace of ind. Ergonoic proportional josticks The proportional josticks are er finel tuned controls for the sensitie, accurate and fluid operation of the achine. This tpe of control is ideal for a achine used in a ariet of applications. Low noise leel and ibrations To diinish fatigue at work and increase productiit, the acoustic power inside the operator s cab is one of the lowest on the arket. The cab is ounted on iscoelastic riets to full absorb the excaator s ibrations. Furtherore, rubber flanges support the pipes and actiel participate in reducing external noise. Touch-screen displa 7-inch touch-screen with colour displa Wide range of adjustent, check, and onitoring possibilities Tough, reliable design (sealing tightness class IP 65) Heightened isibilit Optional rear iew onitoring caera, for optial isibilit and heightened operating safet Optiized design of the whole uppercarriage proiding the operator with an iproed field of ision Front windshield full retractable into the roof, with or without lower glass panel Secure eergenc exit through the rear window Optial teperature Enhanced air-conditioning sste, proiding iproed cooling perforances Optional dark tinted windows R 920 Litronic 11

13 Ease of aintenance All the walking areas of the uppercarriage are coered with antislid aterial to guarantee a safe and eas access. The swing gear is greased for life and requires no dail aintenance. The batteries, all filters and ost centralized lubrication points are accessible fro ground leel, ensuring that dail aintenance and checks are quick and easil perfored. Siplified dail checks The dail checks were taken into account fro the start of the design, to ake the sipler, ore accessible and shorter. The optional autoatic lubrication sste reduces precious sericing tie while guaranteeing optial lubrication of the excaator. Longer serice interals The frequenc of the serice interals is optiised to guarantee that each part is operating optiall and that the aintenance operations are onl perfored as necessar. Whether it is the interal for changing the hdraulic oil, which can be up to 3,000 hours, or the interal for changing the engine oil, eer 500 hours, eerthing has been taken into account to reduce the frequenc of interentions and thus liit the achine s downtie and reduce costs.
