The line-up from Liebherr at Komatek trade fair consists of crawler excavators, a wheeled excavator, wheel loaders and a rotary drilling rig. Liebherr presents the crawler excavators R 944 C and R 954 C. Both are part of the “C-series” and offer a multitude of attachment options, accessory tools and variants providing an optimal configuration to achieve the highest performance in all application ranges. The engine generation as further developed for the “C-series” assures an effective power delivery, a high degree of efficiency, long life expectancy and complies with the emission standard IIIA / Tier 3.
Crawler excavator R 944 C: Versatile concept offers multiple application options
The Liebherr R 944 C on display in Ankara is an exceptionally versatile crawler excavator in the 40 tonnes weight category. Fitted with multiple specialized builds, Liebherr machines in this class have proven themselves in standard earthmoving applications, material handling, demolition, tunneling and many other applications. The combination of large stick and boom cylinders and the optimized attachment geometry facilitate exceptional digging and breakout forces. A hydrostatic fan drive and a separate swing circuit, as well as an efficient air-conditioning system and a sensor-controlled automatic idling also contribute to the standard machine of the R 944 C and reduce fuel consumption. Depending on options, this machine weighs between 38,500 kg and 40,900kg and has bucket capacities from 1.75 m³ to 2.25m³. The R 944 C is powered by a Liebherr D936L inline six-cylinder diesel engine rated at 190kW / 258HP at 1,800rpm.
Liebherr also displays the R 954 C, a crawler excavator in the 50 tonnes class. Equipped with robust design and powered by a 240 kW / 326 HP diesel engine, the R 954 C allows maximum performance under extreme working conditions. Maximum load values and maximum digging forces will be achieved thanks to the optimized steel construction. Depending on attachments, the operating weight is between 49,550 kg to 54,300kg and bucket capacities between 1.65m³ and 3.30m³ as well as shovel capacities between 2.50 m³ and 3.10 m³ are possible.
The equipment is geared to better resist to stresses ensuring therefore a longer service life. For example, safety check valves for stick and boom cylinders with integrated regeneration for less fuel consumption are installed. The parallel kinematics permit a powerful and regular digging. In combination with the sensitive excavator controls assuring optimal efficiency in the interaction of excavator’s hydraulics and electronics, maximum productivity is assured.
