The R 992 crawler excavator: performance and low emissions at CMSE

CMSE (Carrières et Matériaux Sud-Est) is the first customer in France to acquire a new-generation 6.2 crawler excavator.

The R 992 is a robust 94-tonne excavator, specially equipped for extracting abrasive materials. The quarry where CMSE's R 992 operates produces, distributes and sells aggregates for construction sites. After blasting, the excavator loads the pieces of rock into the 3 dumpers that take the material to the crushing station.

Our customer chose a Liebherr G6.2 excavator because they wanted a robust, high-performance machine with low fuel consumption. The 5.2 and 6.2 generations also feature technological innovations such as Liebherr Bucket Fill Assist (BFA) and Liebherr Power Efficiency (LPE).

Our R 980 SME excavator, a unique model for our customer Traineau

To carry out the exploitation of its granite quarry in Aizenay, our customer, Traineau, has chosen our R 980 SME excavator. Offering a global view on the crusher from the cab as well as a reduced fuel consumption, our machine achieves strong performance in terms of lifting and offers every operator a new, unique way of working. Moreover, the comfort it provides is non-negligible: the electric joysticks, the opening of the hatch with the remote control, the suspension of the seat and the interior and exterior soundproofing are all advantages that allow us to say that the R 980 SME offers incomparable flexibil-ity and ergonomics.

After 455 hours of working with our excavator, Traineau is more than satisfied with our services, especially since the front shovel makes loading easier and faster.

The R 980 SME excavator, the ideal tool for mining solid rock

Our customer Traineau chose our R 980 SME excavator because it has proven to be effective in its granite mining opera-tions. Used in a standard mining process, i.e. in activities such as mining, crushing, front-end loading and transportation, our excavator was designed to meet the needs of our customers, and its advantages make it the best machine to choose in quarrying.
