Test in progress: R9400 with D9812 engine in Héming, France

The Liebherr R9400, powered by a D9812 Liebherr engine, Diesel of the year 2017, is going through testing on a cement plant in Héming in the Northeast of France. It is the first large hydraulic excavator with a Liebherr engine.

The R9400 Excavator is currently assembled in Colmar at the plant which is located just next to the D98 engine assembly plant.

This 300 hectare quarry, operated by Eqiom, a CRH company, has an annual production of around 600,000 tonnes of clinker and more than 700,000 tonnes of cement. The two cement kilns have a capacity of 1000 t/day each.

Vertical integration

Liebherr‘s vertical integration practice means that parts are designed specifically by and for Liebherr equipment and components. This allows for optimal availability, longer service life and increased productivity.

The Liebherr D9812 engine asnwers very well to the needs of mining applications and it is, therefore, able to withstand the tough conditions of global mining. It can also adapt to comply with a range of emission standards: Tier 2 or even USA/EPA Tier 4 final.

The V12 engine reaches a power output of up to 1,500 kW for hydraulic excavators and can reach up to 2,013 kW for mining applications.

D98 AND MINING. IT’S A ‘FAMILY FEELING’

 

An enjoyable partnership

Yannick Lauras, project manager at Eqiom in Héming seems to enjoy working with Liebherr. The proximity, the maintenance service as well as the performance of the machines, have contributed to a strong exchange of experience over the years.

In fact, the quarry in Héming operates 3 Liebherr hydraulic excavators: an R994 with backhoe attachment since 1994, an R994 with face shovel attachment since 1998 and an R9250 since 2006. The R9400 with a backhoe attachment and a bucket of 9.5 m³ is going through different tests there since April 2018 and has worked around 350 hours in July / August.

Yannick Lauras said: «We tested it on the hardest layers of material and we reached an extraction volume of 700 t/h. For the overburden, we reach a volume of 1,500 t/h, which is entirely corresponding to our needs. The R 9400 loads 90t trucks in 5 passes».

Also, Liebherr optimized all machine accesses. The operator can access the R9400’s upper structure via a powered 45° stairway fitted with handrails. The large and spacious cab provides ideal working conditions and optimal operator’s comfort.

Mounted on silent blocks, the cab design reduces vibrations and limits noise pollution to provide a quiet working environment.
