1 With a total production of around 800 000 tonnes of aggregate a year, Traineau seems more than satisfied with the R 980 SME excavator and its bottom dump shovel
The Liebherr R 980 SME excavator with bottom dump shovel is in use at Traineau’s granite-quarrying operation at Aizenay in the Vendée department in western France. Ideal for quarrying solid rock, this excavator provides an optimal view of the hopper thanks to its 1.20 m fixed cab elevation. Equipped with a bottom dump shovel, this excavator is a strong performer, with a different way of working from a classic backhoe bucket, explains excavator driver Cédric Di Gallo. The R 980 SME excavator enables very rapid operational cycles, thus increasing efficiency and productivity.
Putting the accent on comfort and safety
In addition to the cab elevation, access to the excavator is improved by a retractable ladder, widened access walkways and a hand rail all along the uppercarriage to assure safe and easy access for the operator and maintenance personnel. These access features were developed for Liebherr mining excavators. Access points are also equipped with timed LED lighting which enables safer access at the start of a shift or at the end of the day.
2 Featuring a bottom dump shovel attachment, this R 980 SME excavator is the first of its type to be delivered in France
This excavator offers a very high level of comfort: with electric joysticks, shovel flap opening via the joystick and semi-automatic flap closing, the seat suspension, and soundproofing inside and out, the R 980 SME can truly be said to provide the ultimate in flexibility and ergonomic design.
The bottom dump shovel that comes with the excavator was developed and manufactured by Liebherr-France SAS in Colmar. With 5.1 m³ capacity, this bottom dump shovel is supplied with a level 3 wear package kit (the highest level) to withstand the abrasiveness of the materials it handles. In this configuration, the bucket weighs in at 11 000 kg. The bucket’s delta blade guarantees optimum penetration into mined materials, even when they are tightly bound to each other.
An excavator tailored to the customer’s needs
Traineau opted for the Liebherr R 980 SME excavator because this model is especially well suited to our customer’s granite quarrying operation. The 104 tonne excavator is used for the various operating phases: rock sorting, rock crushing with the drop-ball, and loading at the quarry face. The shovel attachment is especially effective and accurate in the sorting and crushing processes.
With a total production of around 800 000 tonnes of aggregate per year, Traineau seems more than satisfied with the R 980 SME excavator and its low fuel consumption of 55 l/h. After reaching the 1000 hour mark with the machine, the customer is well placed to confirm that the shovel attachment allows it to reduce cycle times and thus speed up dump truck loading.
