Liebherr presents new R 9200 mining excavator at MINExpo 2016

The mining industry has partnered with Liebherr for half a century, allowing the company to build a solid reputation for the development and production of world-class mining equipment. As a result, the R 9200 combines tradition with innovative thinking, to overcome any challenge.

Optimized for performance

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 12.5m3, 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 1,086hp (810kW). The cutting-edge cab of the R 9200 provides a panoramic view of the operation leading to efficient truck loading and safe machine positioning. The R 9200 integrates an advanced electronic piloting control system which is both intuitive and versatile.

Cost-focused energy management

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 allows the R 9200 to cycle faster and consume less fuel. Efficiency is further enhanced by the use of an on-demand cooling control for both water and oil. The independent cooling circuits eliminate parasitic loss while diverting power to the attachment. By controlling heat, the R 9200’s components operate at their most efficient temperature; efficiency leads to lower costs and a longer life.

Made by Liebherr

Liebherr consistently sets the standard for advanced equipment design and technology with feedback from working machines being incorporated as part of continual improvement processes. Specifically designed for extreme mining conditions, the R 9200’s outstanding reliability and easy serviceability provide maximum uptime. The R 9200 is built on a 50-year foundation that combines experience with innovative thinking, world-class engineering and manufacturing excellence. Central to the foundation are Liebherr’s advanced welding techniques which are stress-relieved and strategically located to ensure the R 9200 is still producing long after the competition has retired. Integrated components developed and produced by Liebherr ensure peak reliability that are synonymous with the Liebherr brand.

Ergonomic design for easy, safe and fast maintenance

The R 9200 is designed with service simplicity in mind. Extended service intervals and purposeful system layouts make the R 9200 easy to service and therefore minimize downtime and lower operating costs. Accessibility of the upper structure is of key note, a powered 45° stairway directs the maintainer to the centralized 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 for the maintainer. Hydraulic pumps are accessible through wide open service doors adjacent to a large catwalk. This combination enables the use of Liebherr’s pump lifting tool for faster replacement. All operating fluids can be easily and quickly refilled through 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 placed in the cab, engine compartment and at ground level.
