R 924 Liebherr excavator specs & Dimensions (2012 - 2019)

Simplified maintenance requires only short interventions

All the maintenance points were designed for easier access and to make the daily maintenance operations shorter. The gull-wing doors provide access to the parts from ground level. The maintenance of most components, such as fuel filters and radiators, is performed in complete safety. Grouped together into very distinct compartments, this machine’s maintenance will save you time and increase productivity on your work sites.

A completely new maintenance concept

Elements within hand’s reach, accessible from ground levelThe filters are grouped together, for shorter maintenance worksAutomatic centralised lubrication as standard

More effective energy management at all times

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.

A new Liebherr engine

Engine complies with Tier 4i/Stage IIIB emission regulationsEspecially designed for construction engine applicationsAutomatic idling system optimises energy efficiency

Hydraulics

Filter with integrated fine filter area. Hydraulic tank shut-off valve and pumps. Liebherr hydraulic oil. Pressure storage for controlled lowering of equipment with engine turned off. Pressure test ports for hydraulic. Stepless work mode selector.

The tradition of quality and robustness

The R 924 crawler excavator is a product designed to withstand major stresses. The robustness of the undercarriage lengthens the service life of the machine. Molded steel parts strengthen the excavator at strategic points for difficult applications. For complete peace-of-mind while working in even the most demanding terrains, the operator’s cab is fitted with an integrated roll-over protection. The operator can concentrate fully on the task: the integrated on-board electronics ensure a constant readjustment to preset values. Any potential divergences from the operating parameters are displayed on the control screen.

A reliable undercarriage

Reliable and robust undercarriage, easy to secure thanks to fitted securing ringsLarge range of undercarriages to meet the needs of different terrainsEasy maintenance and cleaning inherent to the very design of the undercarriage

Under carriage

Upper carriage

Engine hood with lift help Handrails, non slip surfaces Lockable tool box Maintenance-free swing brake lock Sound insulation

Comfort

Another advantage of the R 924 is a space especially created to satisfy the operator’s needs. The cab offers a spacious, comfortable and quiet environment. Its ergonomics definitively enhances the operator’s performance.

A spacious and comfortable work space

In this cab, operators have a pneumatic seat, an enlarged space and an environment with all modern comforts. 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 especially designed for the operators’ well-being. To increase work comfort and productivity, the acoustic power inside the operator’s cab is only 72 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. All the controls are positioned so that the operator can intuitively and accurately manipulate them. The consoles on which the controls and manipulators rest are adjoined to the seat for optimal comfort while working and more accurate movements. A rear-space camera is fitted in the R 924 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 confidence in the tasks they perform.

Operating Weight and Ground Pressure

Operating weight includes basic machine with mono boom 5.70 m, stick 2.40 m, quick coupler 48 and bucket 0.95 m³. Optional: heavy counterweight (Heavy counterweight increases the operating weight by 1,000 kg and ground pressure by 0.02 kg/cm²).

Lift Capacities

The lift capacities on the load hook of the Liebherr quick coupler 48 without attachment are stated in metric tonnes (t), and can be lifted 360° on firm, level supporting surface. Adjacent values are valid for the undercarriage when in the longitudinal position. Capacities are valid for 600 mm wide triple-grouser pads. Indicated loads are based on ISO 10567 standard and do not exceed 75 % of tipping or 87 % of hydraulic capacity (indicated by * ) or are limited through the allowed lift capacity of the load hook on the quick coupler (12 t). Without quick coupler the lift capacities will increase by 250 kg, and without bucket cylinder, link and lever they increase by an additional 365 kg. According to European Standard, EN 474-5: In the European Union excavators have to be equipped with an overload warning device, a load diagram and automatic check valves on the hoist cylinders, when they are used for lifting operations which require the use of lifting accessories. Values are calculated with 500 mm wide triple-grouser pads for the NLC-Undercarriage.
