PerformanceLiebherr 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 efficien-cy, long service life and complies with Tier 3 emission standards.

High ProductivityHigh digging and break-out forces

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.

Regeneration Plus The feature Regeneration Plus guarantees fast at-tachment lowering, reduced pressure loss and in-creased safety. Productivity is increased with the optimization and consolidation of functions: pres-sure less lowering, regeneration and load holding valves all combined with high hydraulic pressure.

Liebherr Engine TechnologyLiebherr Diesel Power 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.

Emission standards The new engine generation with optimal perfor-mance density assures for a more environmentally-friendly fuel combustion. Higher ignition pressures and the newly designed injection technology guar-antee the compliance with the emission standard IIIA / Tier 3.

ReliabilityBacked by more than 50 years experience designing and building hydraulic exca-vators, Liebherr excavators provide the maximum in reliability and performance.

Technology with a visionOptimized hydraulics 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 at-tachment substantially increases the dependability of the hydraulic system.

Power pack The individual components of the drive unit (i.e. con-struction 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 inte-gral part of the total system designed for long life expectancy.

Quality to the last detail

The clearly laid out routing of the hydraulic, lubrica-tion and electrical lines assures the highest reliability and performance of the machine. Optimal corrosion protection is achieved with pre-painted and surface-treated parts.

Heavy-duty attachments Robust attachment concept

Steel castings are utilized at each pivot point - en-suring that the attachment is consistently able to withstand the most severe demands.

Optimized stress flow 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

Lift Capacitieswith Gooseneck Boom 212 and Heavy Duty Counterweight

Capacities are in lb and can be lifted 360 with machine on firm, supporting surface, equipped with 24 wide triple grouser pads. Capacities in ( . . . ) can be lifted over end only. Indicated capacities are based on SAE J 10567 and ISO 10567 and do not exceed 75 % of tipping and 87 % of hydrau-lic capacity (x). Maximum load for the quick change adapters 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.

Lift Capacitieswith Straight Gooseneck Boom 224 and Heavy Duty Counterweight

Capacities are in lb and can be lifted 360 with machine on firm, supporting surface, equipped with 24 wide triple grouser pads. Capacities in ( . . .) can be lifted over end only. Indicated capacities are based on SAE J 10567 and ISO 10567 and do not exceed 75 % of tipping and 87 % of hydrau-lic capacity (x). Maximum load for the quick change adapters 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.
