A world premiere.
With its Generation 6 crawler excavators Liebherr achieves new levels of performance, economy, operating convenience and reliability. The new series of machines, to be shown to the public for the first time at the 2009 'Intermat' trade fair, will set new standards for crawler excavators in the 21 to 28 tonne category.
There are three new-generation crawler excavator models: the R 906 with a service weight of 21.7 - 23.3 tonnes, the R 916 Litronic (23.7 - 26.4 tonnes) and the R 926 Litronic (25.7 - 27.1 tonnes, the figures depending in each case on the machine's equipment specification.
Each of the three new models is powered by a Liebherr four-cylinder construction-machinery engine. The output ratings are 105 kW (143 hp) for the R 906 Litronic, 115 kW (157 hp) for the R 916 Litronic and 130 kW (177 hp) for the R 926 Litronic. These Liebherr construction-industry engines comply with internationally valid exhaust emission limits (stage IIIA / tier 3). Engine management with CAN bus system integration keeps engine speeds more constant and thus optimises fuel consumption and makes more efficient use of the available power.
In response to differing market requirements and customers' wishes, each of the three new crawler excavator models is available in either a 'Classic' or an 'Advanced' version. The 'Classic' Generation 6 versions are intended for typical earthmoving tasks; the 'Advanced' versions are equipped with an even higher level of innovative Liebherr technologies and are thus high-performance 'full option' products, suitable for all kinds of tasks. In addition to earthmoving, their very high performance offers customers valuable benefits in mining, embankment construction, industrial applications or on demolition sites.
