R 944 C Litronic Liebherr excavator specs & Dimensions (2006 - 2011)

Quality to the last detail

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

Liebherr Engine Technology

The 6-cylinder in-line engine, developed for the R 944 C with the new common rail injection assures an effective power output, a high efficiency and a long life expectancy. Already at a low speed range the engine develops a high output and contributes substantially to the economical operation of the entire machine. The new engine generation with optimal performance density assures for a more environmentally-friendly fuel combustion. Higher ignition pressures and the newly designed injection technology guarantee the compliance with the emission standard IIIA / Tier 3.

Power pack

The individual components of the drive unit (i.e. construction equipment engine, travel and swing gearboxes, main pumps and hydraulic cylinders), produced by sister companies of Liebherr are coordinated to fit each other perfectly. They guarantee maximum dependability as an integral part of the total system which is designed for long life expectancy.

Top technology for maximum profitability

This regulating system causes an efficient conversion of the engine output in hydraulic performance which results in better utilization of the available engine power. The result: higher digging forces, shorter cycle times and lower fuel consumption. A unique range of digging tools and quick coupler modules guarantee an economical advantage for jobs with frequent tool changes. Based on years and years of field experience, all components of the Liebherr Tool-Management System originate from its own research and production.

High Productivity

The R 944 C features high digging and break-out forces due to optimal attachment geometry. The remarkable forces are especially accomplished with the utilization of large-size stick and bucket cylinders. The feature “Regeneration Plus” guarantees quicker attachment lowering, less pressure loss and more safety. A high productivity is achieved due to the optimizing and consolidating of the functions “pressure-less lowering”, “regeneration” and “load holding valves” in connection with a high hydraulic output.

Technology with a vision

External bypass lines at the control valve apply the oil flow to the appropriate attachment functions. The optimal hose routing from the control valve to the attachment substantially increases the dependability of the hydraulic system.

Economy

Liebherr crawler excavators stand for maximum productivity. The sensitive excavator controls assure optimal efficiency in the interaction of excavator hydraulics and electronics. A wide selection of attachments, accessory tools and undercarriages with various dimensions provide the correct choice for every application.

Heavy-duty attachments

With the utilization of steel castings at every pivot point, the attachment is consistently able to withstand the most server 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.

Maintenance friendly track components

Top rollers, track rollers and track link pins are lubricated for the life of the excavator. The grease cylinder of the idler tensioner is sealed against dirt.

Comfort

In the operator’s station, the operator can look forward to a comfortable workstation that is designed according to the most up-to-date ergonomically know-how. The standard automatic climate control provides a pleasant working environment in all weather conditions. Liebherr crawler excavators are particularly service-friendly: Maintenance work is simply and quickly accomplished due to well accessible service points.

Easy operation

The control consoles and information display are arranged within clear view of the operator and are easy to reach. New joysticks, with reduced operating force, are ergonomically shaped and allow pleasant and fatigue-free work.

Standard maintenance advantage

All service points are easily accessible and the R 944 C features a central lubrication point as a standard feature. Daily preventive maintenance can be completed in a short period of time.
