Mining excavators

03/24/2015

Recycling GmbH Lahnau deploys a Liebherr R 970 SME crawler excavator in a chalk pit in Dornap near Wuppertal (Germany). With an operating weight of approximately 80 tonnes, the crawler excavator was developed and manufactured in Colmar (France). Its diesel engine returns 330 kW / 449 HP and complies with emissions standard stage IIIB / Tier 4i.

Since the Liebherr R 970 SME was commissioned, it has completed about 2,000 hours of operation in total and up to 50 operating hours per week.

The SME crawler excavators from Liebherr are particularly suitable for deployment in quarrying and extraction. SME stands for “Super Mass Excavation”. These crawler excavators are equipped with a reinforced undercarriage featuring components from the next model up in the product range. As such, the R 970 SME is equipped with the undercarriage of the R 976 model. Compared with the standard version, the ballast weight is also higher. This means that not only is the stability of the machine assured but buckets with a greater volume can be used.

The SME product range from Liebherr also includes the models R 950 SME, R 960 SME and R 980 SME.
