Birth of a Beast Liebherr hard at work oN Bauma behemoth

At Bauma 2016, Liebherr will unveil its new entry into the 200 tonne excavator class: the R 9200.

The new machine, which features a class-leading 12.5 m3 capacity bucket, offers sustainable performance while delivering peak fuel burn efficiency, even in the most challenging conditions. This world-class mining excavator is designed to match mining trucks with payloads of up to 140 tonnes.

The R 9200 is available in backhoe and face shovel configuration and is fitted with the Liebherr advanced bucket and GET solution. With a standard bucket volume of 12.5 m3, the R 9200 bucket solution delivers superior digging performance and high fill factors, even in the most extreme mining conditions. This new excavator is powered by the Cummins QSK38 diesel engine that complies with USA/EPA Tier 2 or 4i exhaust emission limits and has a rated output of 810 kW. The cutting-edge cab of the R 9200 provides the operator with a panoramic view of their operation, which leads to efficient truck loading and safe machine positioning. The R 9200 integrates an advanced electronic piloting control system which is both intuitive and versatile.

The Liebherr R 9200 excavator is equipped with the unique Liebherr-patented Litronic Plus system, an intelligent power management system that enhances electrical, mechanical and hydraulic power distribution. Combined with a closed-loop hydraulic swing circuit, this class-leading system means the R 9200 cycles faster and consumes less fuel without sacrifice. Efficiency is further enhanced through the use of on-demand cooling control for both water and oil. The independent cooling circuits eliminate parasitic loss while diverting power to the attachment. By eliminating heat, the R 9200’s components operate at their most efficient temperature; efficiency leads to lower cost and a longer life.

The R 9200 is designed with service simplicity in mind. Extended service intervals and purposeful system layouts make the R 9200 easy to service; minimising downtime and lowering operating costs. Accessibility of the upperstructure is of key note, a powered 45° stairway directs the maintainer to the centralised major service points which can be quickly and easily reached from this single-level service platform. The engine too, is surrounded by wide platforms leading to effortless and safe access to the maintainer. Hydraulic pumps are accessible through wide open service doors adjacent to a large catwalk. The combination enables the use of Liebherr’s pump lifting tool meaning faster replacement. All operating fluids can be easily and quickly refilled through the ground- level service access.

The R 9200 eliminates hazards to ensure a safe environment for the service staff during maintenance. Numerous service lights are strategically located in service areas to maintain suitable maintenance conditions, day or night. Additionally,emergency stops have been strategically placed in the cab, engine compartment, and at ground level.
