Liebherr offers the R 992 crawler excavator for large-scale construction. The R 972, R 978 SME, R 992 and R 998 SME models replace the R 966, R 970 SME, R 976 and R 980 SME models respectively.
CMSE (Carrières and Matériaux Sud-Est) uses the R 992 crawler excavator to extract rocks at its quarry at Saint-Pons-de-Thomières (France). This 94 tonne machine is specially equipped for extraction work.
Liebherr Bucket Fill Assist (BFA) and Liebherr Power Efficiency (LPE)
The R 992, like all models of the new generation, comes with the Bucket Fill Assist (BFA) assistance system and the Liebherr Power Efficiency – Engine Control (LPE) system. CSME uses BFA for high bucket filling level and penetration into the rock. CMSE also utilizes the Liebherr Power Efficiency – Engine Control (LPE) system, which provides control of machine power. It actively regulates engine speed and the hydraulic pumps’ angle of inclination.
Overview of CMSE
The Saint-Pons-de-Thomières quarry, where the R 992 is in operation, produces, distributes and sells aggregates for public works construction sites and has previously supplied materials for race car tracks in France and other countries.
The choice of a Liebherr Generation 6.2 excavator was based on the customer’s wish to acquire a high-performance machine with low fuel consumption. As a holder of the UNICEM Cap Environment label, the CMSE is particularly keen to reduce CO2 emissions across its entire fleet.
