Liebherr R 978 SME Excavator Combines Precision and Efficiency

The R 978 SME crawler excavator from Liebherr France SAS is designed for high-volume earthmoving in demanding environments. Weighing 78.5 tonnes, the machine features reinforced components, a custom 2 m³ bucket with crusher-grade wear plates, and advanced hydraulic systems that deliver both power and precision. Part of Liebherr’s new generation of crawler excavators over 70 tonnes, the R 978 SME also provides operator comfort, low noise levels, and adjustable settings through the Modetronic control system, which allows movements and performance to be tailored to both task and operator preference.

Built for Super Mass Excavation, the SME series combines a reinforced undercarriage, enlarged counterweight, and optimized attachment kinematics to provide exceptional digging and breakout forces. The machine’s Liebherr Power Efficiency (PE) Engine Control system can reduce fuel consumption by up to 15 per cent compared with previous models, while working modes allow operators to adapt performance to site conditions. On-site training from Liebherr and its partners ensures operators can make the most of these capabilities efficiently and safely.
