5 Performance Liebherr crawler excavators feature state-of-the-art technology and high-quality workmanship. The critical components of the drive system are all produced by Liebherr factories and are perfectly coordinated to each other. The Liebherr diesel engine assures effective power delivery, exceptional efficiency, long service life and complies with Tier 3 emission standards. High Productivity High digging and break-out forces Regeneration Plus Liebherr Engine Technology Liebherr Diesel Power Emission standards The R 944 C features high digging and break-out forces due to optimal attachment geometry - due to the utilization of large stick and bucket cylinders. The feature Regeneration Plus guarantees fast attachment lowering, reduced pressure loss and increased safety. Productivity is increased with the optimization and consolidation of functions: pressure less lowering, regeneration and load holding valves all combined with high hydraulic pressure. The 6-cylinder in-line engine, developed for the R 944 C assures an effective power output, a high efficiency and a long life expectancy. The engine develops high output power at low rpm - resulting in economic operation without sacrificing power. The new engine generation with optimal performance density assures for a more environmentallyfriendly fuel combustion. Higher ignition pressures and the newly designed injection technology guarantee the compliance with the emission standard IIIA / Tier 3. Heavy-duty undercarriage Combination of high-strength steel plates with steel castings for a smooth stress flow Multi-function tool carrier Attachments for every material and application Modular quick coupler system designed and manufactured by Liebherr LIKUFIX: a quick change system that combined with an automatic coupling system allows the operator to quickly change attachments and make all hydraulic connections from the cab R 944 C Litronic 5

7 Reliability Backed by more than 50 years experience designing and building hydraulic excavators, Liebherr excavators provide the maximum in reliability and performance. Technology with a vision Optimized hydraulics Power pack Quality to the last detail Heavy-duty attachments Robust attachment concept Optimized stress flow External bypass lines at the control valve route the oil flow to the appropriate attachment functions. The optimal hose routing from the control valve to the attachment substantially increases the dependability of the hydraulic system. The individual components of the drive unit (i.e. construction equipment engine, travel and swing drives, main pumps and hydraulic cylinders), pro duced by Liebherr are coordinated to fit each other perfectly. They guarantee maximum dependability as an integral part of the total system designed for long life expectancy. The clearly laid out routing of the hydraulic, lubrication and electrical lines assures the highest reliability and performance of the machine. Optimal corrosion protection is achieved with pre-painted and surfacetreated parts. Steel castings are utilized at each pivot point - ensuring that the attachment is consistently able to withstand the most severe demands. The swing ring tower is made from one piece, which transfers the forces following the principal of stress flow design - into the undercarriage. For lasting protection against dirt and damage, Liebherr swing rings are sealed and have internal teeth. Bucket linkage Optional sealed linkage bearings Optimal protection for under-water work Increased life expectancy of the attachment Key components made by Liebherr All components designed and manufactured for construction applications Engines, hydraulic pumps and motors, swing and travel drive and electronic elements - all manufactured in-house by Liebherr State-of-the-art component production facilities in Germany and Switzerland R 944 C Litronic 7

9 Comfort Designed to the latest ergonomic standards, the operators cab provides exceptional comfort, ease of operation and an outstanding, wide view to the working area - with air-conditioning standard. For Liebherr, comfort also applies to service, with centrally located service points and easy, rapid access. Standard maintenance advantage Easy accessibility Maintenance friendly track components The operator takes center stage Optimal visibility Well thought-out arrangement Easy operation All service points are easily accessible and the R 944 C features a central lubrication point as a standard feature. Daily preventive maintenance can be completed quickly and easily. Top rollers, track rollers and track link pins are lubricated for the life of the excavator. The grease cylinder of the idler tensioner is sealed against dirt. The cab features exceptional window area - providing outstanding visibility to the work and surrounding area. Designed to the latest ergonomic standards, the controls, displays, the arrangement of the seat - all are perfectly tuned in an integrated concept. The seat is fully adjustable to ensure maximum operator comfort over a long work day. The control consoles and information display are arranged within clear view of the operator and are easy to reach. New joysticks, with reduced operating force, are ergonomically shaped and placed in easy reach of the operator. Easy access Comfortably positioned steps on both sides provide good accessibility to all service points Ergonomically positioned hand rails ensure secure access Additional hand rails guarantee maximum safety Liebherr Operator s cab Generously-sized windows allow for optimal visibility Right-side window without vertical center post Standard automatic climate control Operator s seat is individually adjustable and includes a shock-absorbing cushion Lockable storage behind seat R 944 C Litronic 9

Maximum load for the quick change adapter s load hook is 39,683 lb. Without the quick change adapter, the lift capacity increases by 992 lb, without the bucket cylinder, link and lever, they increase by an additional 1,300 lb. Safe lifting capacity of the excavator is limited by machine stability, hydraulic capacity and maximum permissible load on the load hook. R 944 C Litronic 17
