R 922 Liebherr excavator specs & Dimensions (2013 - 2019)

Economy

The R 922’s new maintenance plan helps reduce time spent on interventions on the excavator, giving increased productivity. Operating costs are also reduced thanks to even more intelligent energy management and automatic tool changing.

Intelligent and efficient energy management

The engineering of Liebherr’s integrated systems and the effective management of the engine and hydraulics are constantly controlling fuel consumption. The new diesel engine, automatic idling, electronic engine speed sensing regulation and Regeneration Plus are just some of the elements that contribute to better energy management. This consumption control minimises the discharge of toxic gases into the atmosphere whilst saving on operating costs. The R 922 also complies with the European Stage IIIB exhaust gas emission regulations with its oxidation catalyst technology.

Liebherr integrated systems engineering

According to requirements, the two circuits of the hydraulic system pumps are either separated or combined, for levelling operations, or transfer movements in a straight line or curve. The separation of the two circuits allows each actuator to be powered by appropriate pressure in an independent and energy-saving manner. For its part, the combination of the two circuits allows maximum speed to be reached for simple or combined movements.

A single shovel for a multitude of applications

The R 922 is an excavator suitable for all types of work with its vast range of Liebherr attachments. Different sticks can be combined with a variety of booms (mono boom, straight mono boom, offsettable and two-piece boom). A long attachment is also available. Finally, to facilitate tool-changing, a hydraulic quick coupler and the Likufix system are offered as options.

Robustness at all levels

The robustness of the undercarriage lengthens the service life of the machine. Liebherr selects high quality materials for building the undercarriage and can meet the needs of all its customers by offering a large variety of X-shaped undercarriages. Furthermore, large openings between the track carriers and the centre piece of the undercarriage will make them easier to maintain, as will the steps on the vertical side of the track carriers.

Liebherr R 922 Crawler Excavator

The Liebherr R 922 crawler excavator is a product designed to withstand major stresses. The attachments are fitted with cast steel parts strategically positioned on the joints. In addition, the continuous optimisation of the structure allows it to achieve the long service life that customers require.

The R 922 : an excavator that, quite simply, gets the job done

All the maintenance points have been designed for easier access and to shorten maintenance operation times. The gull-wing hood openings allow the service points to be accessed from the ground. The maintenance of most elements, such as the air filter, the fuel filters, the engine oil filter and the radiators, is carried out in full safety. The grouping together of the maintenance points into completely separate, easily accessible compartments increases speed and productivity in the worksites.

Roll-Over Protection System

The cab is fitted with a roll-over protection system, called ROPS. It is invisible and allows the operator to work in complete confidence.

Even better working conditions

In this cab, the operator has a pneumatic seat, an enlarged space and a very comfortable work environment. Depending on the operator’s needs, the Liebherr Premium seat can be chosen as an option. This seat offers maximum seating comfort with its pneumatic lumbar support, its electronic weight-actuated height adjustor and its air-conditioning with activated charcoal and built-in fan. It is especially designed for the operators’ well-being.

Comfort and Noise Reduction

To increase work comfort and productivity, the acoustic power inside the operator’s cab is only 71 dB. The cab is mounted on viscoelastic rivets that ensure the vibrations are fully absorbed. The rubber flanges that support the pipes also actively participate in reducing external noise.

Visibility and Safety Features

A rear-view camera is fitted in the R 922 counterweight. A display on the 7" high resolution screen allows the operator to work in a secure area. A side camera is also available as an option. This complete visibility gives the operators full confidence in the tasks they perform.

Automatic centralised lubrication as standard

The fully automated lubrication system is a true time-saver for the operator, with minimum machine downtime. In parallel, it increases the service life of the moving elements with appropriate lubrication and contributes to site safety by preventing the operator from having to get down from the machine.
