Advanced techniques heighten performace
In its design offices, Liebherr combines the technological know-how of each area to creat consistent and optimised intergrated systes. Liebherr's electronics, positive control hydraulics, and even the travel motors are designed from the start to be interconnected and generate optimum operating power with fast and fluid movements.

Positive Control hydraulic system
Two working pumps for maximum excavation, travel or swing efficience, provide power to the components involved. Thanks to the positive control system, the combined movements are optimised for each different work operation, whether this be levelling, extraction, loading or lifting, with or without travel.

Particularly fast work cycles
The work cycles of the R 920 are very fast thanks to the large sized transmission components. For example, the uppercarriage's swing drive can quickly reach its maximum speed with a high swing torque.

Operating Pressure
Maximum digging and break-out forces can be reached thanks to the level of hydraulic pressure, without applying temporary overpressure. Maximum forces are therefore guaranteed continuously during the whole working phase to achieve a high level of production. to further improve the machine performances, the equipment speed is optimized through an intergrated regeneration circuit.

  • Cummins engine stage
       IIA / Tier 3
  • Designed specifically for
        construction applications
  • Automatic fuel-saving idling
        system
  • "Wastegate" turbo for
        enhanced performances at low
        speed and reduced
        consumption
  •  
  • Robust design for
       greater resistance and a
       better distribution of forces
  • Easy and safe transport thanks
        to intergrated lashing eyes
  •  
  • Higher digging and break-out
         forces for increase in
         productivity
  • New optional pads available in
         700 and 800 mm for more
         versatility
  • New swing motor for higher
         swing torque speed

  • Less fuel
    Associated with the latest developments in technology and hydraulics, the tried-and-tested 6-cylinder Cummins engine consumes little fuel, both in terms of hours of operation and in terms of tons of material moved.

    Increased productivity
    Clearly enhanced performances and low consumption, combined with the largest fuel tank on the market, all in a comfortable and ergonomic work environment, lead to significant increases in productivity in all operating configurations.

    Electronic power control
    This control system allows the engine power to be effectively and optimally converted, from an energetic point of view, into hydraulic power. this results in greater forces, a faster working speed and a lower fuel consumption.

  • Quality in the smallest details
    Robust and large-sized components, optimal fitting of electrical and hydraulic lines, or an exemplary level of finishing are just some of the many criteria that ensure a maximum quality of manufacture and operability.

    A top-of-the-range anti-corrosion protection
    A pre-assembly painting process guarantees that all painted parts are fully coated. The use of a high-quality paint provides resistance against extreme external conditions.

    Perfect match
    The individual components of the power train such as the diesel engine, gears, swing drive, working pumps and hydraulic cylinders are specifically dimensioned to work toegether in a global means that they are all compatible with each other in a global system, guaranteeing higher reliability and a longer service life.

    Automatic control of functionality
    The operator can entirely focus on his job, because the intergrated on-board electronic continuously performs a comparison with pre-determined target data. eventual deviations from the target parameters are shown on the display.

  • Over 80,000 spare parts in
        stock at all times
  • Ease of Maintenance
    All the walking areas of the uppercarriage are covered with anti-slid material to guarantee a safe and easy access. The swing gear is greased for life and requires no daily maintenance. The batteries, all filters and most centralized lubrication points are accessible from ground level, ensuring that daily maintenance and checks are quick and easily performed.

    Simplified daily checks
    The daily checks were taken into account from the start of the design, to make them simpler, more accessible and shorter. The optional automatic lubrication system reduces precious servicing time while guaranteeing optimal lubrication of the excavator.

    Longer service intervals
    The frequency of the service intervals is optimised to guarantee that each part is operating optimally and that the maintenance operations are only performed as necessary. Wether it is the interval for changing the hydraulic oil, which can be up to 3,000 hours, or the interval for changing the engine oil, every 500 hours, everything has been taken into account to reduce the frequency of interventions and thus limit the machine's downtime and reduce costs.
