THE LIEBHERR R 992 CRAWLER EXCAVATOR: HIGH PERFORMANCE AND LOW EMISSIONS AT CMSE
CMSE (Carrières & Matériaux Sud-Est) uses the R 992 crawler excavator to extract rocks at its quarry at Saint-Pons-de-Thomières (France). www.liebherr.com The Colas R 992 crawler excavator is specially equipped for the client’s application. CMSE is the first customer in France to acquire a new-generation crawler excavator. This 94-tonne machine is specially equipped for extraction work. The improvements and technological innovations in the range guarantee performance and versatility on the ground. Liebherr’s Generation 5.2 and 6.2 crawler excavators, in the 70–100 tonne range, were inveiled to the public at the last Bauma. 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. These new excavators, developed with a particular focus on reducing fuel consumption, also feature other improvements, such as enhanced performance data, optimal operator comfort and new operator assistance functions. Challenging working conditions in the extraction of blue quartzite Extracting rock in quarries is the R 992’s main task at the site of CMSE (Carrières & Matériaux Sud-Est). The machine’s high tooth force, reliability and precision are guarantees of quality in this challenging application. It is specially equipped with piston rod guards, an HD undercarriage and a 5.20 m3 HDV bucket with guide rails for a drop ball. The bucket is specially reinforced, as the high abrasiveness of digging blue quartzite, the primary product from this quarry, demands a specifically adapted cutting tool. After blasting, the excavator loads lumps of rock into the three dump trucks that take the material to the crushing station. The enlarged, reinforced bucket is ideal for extracting solid rock. Liebherr Bucket Fill Assist (BFA) and Liebherr Power Efficiency (LPE) improve performance 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 a higher bucket filling level and optimal penetration into the rock. This system improves operator comfort by reducing vibration and reduces fuel consumption by 10%. At less than 60 litres per hour, the excavator’s current fuel consumption is lower than that of their previous excavator. CMSE also appreciates the Liebherr Power Efficiency – Engine Control (LPE) system, which provides optimal control of machine power. It actively regulates engine speed and the hydraulic pumps’ angle of inclination. www.liebherr.com Powered by Induportals Media Publishing
