3Comfort The operator™s well-being is a fundamental consideration for Liebherr when developing its products. Liebherr™s ex -cavators, including the R 920, all have a quiet, ergonomic and spacious operator™s cab that fully satis˜es the op -erator™s needs. This outstanding comfort is very highly appreciated. And ˜nally, the enhanced visibility of the machine™s direct work environment allows the operator greater peace of mind while performing their daily work. ReliabilityWith 50 years of experience designing and manufactur -ing hydraulic crawler excavators, Liebherr France SAS is in a strong position to offer its customers ever more reli -able machines. The high quality of the product is guaran -teed at all the stages, from design to manufacture, while the safety and comfort of the operator™s working condi -tions have been enhanced even further. This recognized reliability is also to be found in the numerous services that Liebherr has speci˜cally developed for assisting and satisfying its customers. Performance Liebherr™s R 920 combines power, precision and versa -tility. Its characteristics guarantee its excellent perfor -mance in a wide variety of applications, including the toughest. And its movements attain an unequalled level of smoothness and precision thanks to the latest genera -tion hydraulic system. The R 920 is therefore suitable for both light and heavy daily tasks. The dozing blade, a key feature of this excavator, is added to a vast range of tools and undercarriages which make it essential. EconomyThe grouping together of the maintenance components and their accessibility from ground level reduces inter -vention times on the R 920. The automatic centralised lubrication system ˜tted as standard and the intelligent energy management increase the excavator™s produc -tivity. Therefore the return on investment of the R 920 is guaranteed.

5Performance Liebherr™s R 920 combines power, precision and versatility. Its characteristics guarantee its excellent performance in a wide variety of applications, including the toughest. And its movements attain an unequalled level of smoothness and precision thanks to the latest generation hydraulic system. The R 920 is therefore suitable for both light and heavy daily tasks. The dozing blade, a key feature of this excavator, is added to a vast range of tools and undercarriages which make it essential. Liebherr integrated systems engineeringCutting-edge technology for high performance The R 920 excavator incorporates Liebherr™s Positive Control hydraulic system. This system is controlled by Liebherr electronics and uses strategically-posi -tioned sensors. All of the machine™s work is therefore faster, more accurate and ˚uid. What™s more, as the two hydraulic pump circuits can operate either sepa -rately or together, this optimises the energy manage -ment of the R 920. Harmony between versatility and power From power to performance The excellent productivity and high performance of the R 920 are the results of intense research. In particular, this machine has a clean and ef˜cient 105 kW engine that complies with the requirements of the new Stage IIIB regulations on exhaust gas emissions. The optimal kinematics of the attach -ments allows the R 920 to reach a break-out force of 126 kN and a penetration force of 99 kN, while simultaneously increasing its lifting force. The Liebherr Tool-Control System The Tool-Control function makes it easy to change tools thanks to recognition of the chosen tool™s sys -tem. It makes the programmed pressure and ˚ow values available from the moment the hydraulic tool is changed. Consequently, the crawler excavator has more availability for productive tasks, and ad -justment times are reduced. Intelligent work modes Ł Economy mode: for an economic and ecological operation. Recommended for normal working conditions Ł Power Mode: for high excavation capacities in dif˜cult applications Ł Sensitivity Mode: for accurate load-lifting applications Ł Full Power Mode: especially designed for higher power, ideal for extreme applications An effective and accurate dozer blade Ł Radial fan blade Ł Different blade lengths available Ł Impeccable levelling quality and precision Ł Only two lubrication points Ł Cylinder rod protection as standard Ł Fitted tie-down eyelets

9Comfort The operator™s well-being is a fundamental consideration for Liebherr when de -veloping its products. Liebherr™s excavators, including the R 920, all have a quiet, ergonomic and spacious operator™s cab that fully satis˜es the operator™s needs. This outstanding comfort is very highly appreciated. And ˜nally, the enhanced visibility of the machine™s direct work environment allows the operator greater peace of mind while performing their daily work. When work becomes pleasureA ˜rst class work space In this cab, the operator has a pneumatic seat, an enlarged space and a very comfortable work envi -ronment. Depending on the operator™s needs, the Liebherr Premium seat can be chosen as an option. This seat offers maximum seating comfort thanks to its pneumatic lumbar support, its electronic weight- actuated height adjustor and its air-conditioning with activated charcoal and built-in fan. It is espe -cially designed for the operators™ well-being. Sound level and vibrations reduced to a minimum To increase work comfort and productivity, the acoustic power inside the operator™s cab is only 68 dB. The cab is mounted on viscoelastic rivets that ensure the vibrations are fully absorbed. The rubber ˚anges that support the pipes also actively contribute to reducing external noise. A panoramic view of the whole work area A rear-space camera is ˜tted in the R 920 counter weight. A display on the 7″ high resolution screen allows the operator to work in a secure area. This complete visibility gives the operator full con˜dence in the tasks they perform. Fully automatic air-conditioning Automatic air-conditioning as standard has more than 12 adjustable ventilation outlets, for the indi -vidual control of air ˚ow. The system can be con -trolled via the touch screen. Spacious and comfortable operator™s cab Ł Several storage spaces behind the seat, with optional chillers for keeping drinks cool at all times Ł Fully retractable windscreen, stowable under the roof Ł Fully automatic air-conditioning with fast de-icing and defogging functions Ł 12 V plug for operating the optional chiller, and all other types of appliances Ergonomic and precise joysticks Ł Sensitive joysticks with proximity switches allows greater responsiveness while resuming rpm Ł Joysticks ergonomically positioned for greater comfort during work and enhanced movement precision Ł The proportional control allows a very ˜ne manoeuvrability for a sensitive, accurate and more ˚uid operation of hydraulic tools
