5 Performance Thanks to its innovative system technology, the R 916 and R 926 crawler excavators have performance features that are truly unique. The energy efficient Positive Control dual-circuit hydraulic system is designed specifically to allow multiple functions or machine movement at the same time. The electronic pump control sets a new standard for performance and efficiency. integrated excavator system technology High-tech for high performance Positive Control dual-circuit hydraulic system Power and speed Faster work cycles R 916 operating pressure R 926 operating pressure The excavators features the newly-developed integrated excavator system technology. This is based on the Positive Control hydraulic system, controlled by Liebherr electronics and the system software. The sensors located at strategic points on the machine form the basis for an intelligent system that allows for fast and efficient work. When traveling straight, turning or performing work functions, the two hydraulic pump circuits are either grouped together or operated independently. Operating separately, the pumps can supply components with different load pressures and flows independently, while combining the flow for maximum speed and multiple functions for optimum efficiency. The excavators features quick working cycles attained as a result of the Liebherr swing drive and exceptionally high swing torque. With an operating pressure of PSI, the R 916 achieves higher hydraulically limited load capacities and higher digging forces, of up to lbf, and break-out forces of up to lbf; perfect for difficult applications. With an operating pressure of PSI, the R 926 achieves high hydraulically limited load capacities and higher digging forces, of up to lbf, and break-out forces of up to lbf. Wide range of operational possibilities Large number of equipment options Adaptable to a wide range of applications from earthmoving to demolition Powerful Liebherr engines Four-cylinder diesel engines developed and manufactured by Liebherr specifically for construction machines, with system integration by means of CANBus and pump line nozzle injection system Efficient power output, and long service life High output performance and torque at low rpm R 916 Litronic R 926 Litronic 5

7 Reliability Backed by more than 50 years experience designing and building hydraulic excavators, Liebherr designed the new Generation 6 Excavators to provide the maximum in reliability and performance. High stability undercarriage Improved force distribution High performance travel drive Technology with perspective Quality right down to the finest detail ROPS cab structure Ready for the demands of the future The new undercarriage concept of the Generation 6 crawler excavators increases performance and improves service life. The center section is extended to the ends of the side frames in an improved X frame design - resulting in improved distribution of load forces. Thanks to a powerful travel drive, the Generation 6 crawler excavators are well suited for travel and transport of loads across difficult terrain. The large sprocket reduces track vibrations and increases travel speed to 3.8 mph (6.1 km/h), making the R 916 and the R 926 the fastest excavators in their class. The layout of the hydraulic lines, lubrication lines and points, wiring harness, etc., all designed for maximum reliability. The cab is equipped with an integrated roll-over protection system (ROPS) in accordance with ISO The Liebherr system technology can be updated at any time by Liebherr Service personnel to a newer version - making it ready to meet the demands of the future and prepared for future developments and options. Key technologies Made by Liebherr Decades of experience in the development, engineering and production of components Engine, hydraulic pumps, transfer gears, travel drives, swing drives, swing rings, and electronic components all from the same source Main steel components, such as undercarriage, equipment modules, and superstructure, all designed by Liebherr Spare Parts Extensive USA spare parts inventory located at Liebherr s Newport News, Virginia headquarters Parts support is supplemented by the western USA warehouse located in Phoenix, Arizona 24 / 7 parts support with a dedicated after hours support number R 916 Litronic R 926 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. For Liebherr, comfort also applies to service, with centrally located service points and easy, rapid access. Safe work with a clear layout A pleasant workplace The entirely new design of the R 916 and R 926 cab includes a two part, retractable windshield made of break-resistant double pane safety glass - also used in the roof and right-side glass. The cab meets ROPS requirements per ISO High-resolution color display Wide camera viewing field Fully automatic climate control system Minimal noise and vibration The 7-inch, high resolution color display features an integrated view from the rear-view camera. The screen can be operated via a rotating/pushbutton arrangement or via an optional touch screen and is designed to be glare free. The optional rearview camera for the R 916 and R 926, with a viewing angle of more than 120º, provides a complete view of the area behind the machine. The climate control system has more than 12 adjustable vents for individual control of air flow, and can be operated via the display. For heating operation, the fuel-saving Econ mode is available, in which the climate control compressor is switched off. The new cab on the Liebherr crawler excavator meets the European standards for noise emissions and whole-body vibrations. cab Features of the cab: Newly developed operators position as standard Air-suspension seat with automatic weight adjustment and horizontal suspension for maximum comfort standard For optimum ease of operation and fatigue-free work, the operating consoles pivot with the seat Extremely maintenance-friendly All maintenance points are easily accessible Daily routine servicing work can be carried out very rapidly, reliably, and in comfort Fully automatic central lubrication system - standard R 916 Litronic R 926 Litronic 9

11 Economical Crawler excavators from Liebherr guarantee maximum productivity. The optimized interaction of hydraulics and electronics means that individual movements as well as multiple functions can be performed at the same time without decreasing efficiency. Economical technology Costs savings thanks to fuel efficiency Fuel savings are achieved thanks to the integrated excavator system technology and the efficient engine and hydraulics management. When not performing a task, the sensor-controlled function automatically idles the engine, reducing fuel consumption and emissions. Value High quality Environmental protection and recycling Liebherr excavators are engineered and built to last, with high quality materials and superior workmanship - guaranteeing a long service life. All Liebherr engines meet the exhaust gas directives specified by law, of Stage IIIA/ Tier 3, which means reduced nitrogen oxide and fine dust emissions. With Liebherr, concern for the environment is extended to the whole machine. Up to 95 % of all the components from a Liebherr excavator can be recycled, and only lead-free paints are used.
