5 Performance The R 924 B features excellent lift capabilities, high digging and breakout forces and fast cycle times. The drive system is designed and manufactured by Liebherr and provides high output reserves. High Productivity Excellent lift capacities High digging-and breakout forces Short cycle times The R 924 B allows the use of high-volume buckets due to exceptional lift capacities - the result is excellent productivity for this machine class. Due to optimized attachment geometry and large stick and bucket hydraulic cylinders, the R 924 B provides high digging and breakout forces. High displacement hydraulic pumps make short cycle times possible. The coordinated and simultanious functions are a result of precision matched Liebherr components such as engine, pumps, swing drive and control unit. Solid footing Stability Outstanding lift capacities Large ground clearance Effective utilization of the digging forces is achieved due to the weight concentration in the undercarriage. The excellent stability under all ground conditions is one of the outstanding features of the R 924 B. The low center of gravity combined with the wide base of the undercarriage allow for the high lift capacities of the R 924 B. The distance between the carbody and the ground assures substantial protection of the undercarriage components as well as easy travelling under difficult ground conditions. Heavy-duty undercarriage Choice of undercarriages to meet job requirements Minimized tension due to the use of high-tensile strength steel plates and steel castings Track tensioner and grease cyclinder protected against dirt Multi-function tool carrier Digging tools for every material and application Change tools quickly and easily with the modular quick coupler system designed and manufactured by Liebherr: Optional Liebherr quick coupler adapter for the change-over of mechanical tools R 924 B Litronic

6 Unique design for hoist cylinder mounting The R 924 B is the only machine in this class with two separate pins at the upper deck end Maximum strength even at high load factors Bell-house castings for maximum strength and ease of effort for assembly and disassembly 6 R 924 B Litronic

7 Reliability Liebherr crawler excavators prove everyday at construction sites all over the world thier high reliability, productivity and longevity. 0 years of experience in designing and building excavators, continuous development and the use of the latest technologies make the R 924 B one of the most powerful and dependable excavators available. Quality down to the last detail Power Package Pre-finish Heavy-duty attachment concept Heavy-duty attachments Optimized stress flow Safety of functionality Automatic control Data storage Liebherr manufactured components in the drive system, e.g. engine, travel and swing gearboxes, hydrualic pumps, motors and cylinders are precisly matched to one another. As elements of a total system, each component contributes to the long service life and high reliability of the Liebherr R 924 B. Excellent workmanship is evident throughout the R 924 B: every individual component is entirely painted or surface treated to protect against corrosion. Liebherr excavators utilize steel castings at every pivot point, the result is that the attachment is able to withstand even the most demanding operating conditions. Liebherr swing rings are sealed and have internal teeth to protect against dirt and damage The operator can concentrate on the job at hand because the integrated on-board electronic system will alert the operator to any discrepencies that occur. The on-board computer stores all machine data. The data can be easily recalled and transferred by radio to a service center.
