“SOMTP Centre can use the opportunity to present the R 950 SME
to us as an alternative to its most important competitors’ products,”
Fabien Denis adds. The Liebherr engine in the R 950 SME has six cylinders and a
power output of 220 kW, and it complies with European emissions
standard Tier 4i /Stage IIIB. It is equipped with a particulate filter
with active regeneration. “That is something new for us,” Alexandre
Favin says. The degree of contamination is shown on the monitor
display in the cab. When regeneration is due, it starts automati-
cally without interrupting work. “I can defer regeneration, for
example, to the next day if it becomes due near the end of the
day,” Jean-François Méry reports.
The R 950 SME has been in operation since the end of May 2013.
“It is dynamic and has a high rpm speed,” Jean-François Méry
declares. He also appreciates the comfort of the driver’s cab and
the low noise level of the excavator.
“The dumper truck is just what we need,” says Alexandre Favin.
“It is a highly versatile excavator.” Half the time it is used in pro-
duction. The rest of the time it is used for spoil work, loading
blocks, and exploratory work at new parts of the quarry. “The
R 950 SME is equipped for high-volume turnover, which extends
its range of applications. The excavator driver is able to choose
the most suitable of four working modes for his current work,”
Alexandre Favin adds. “In addition, our excavator driver asked
us to choose the optional boom float function, which prevents
unnecessary loading of the excavator and improves comfort for
our driver.” The operations manager knows the benefit of the
excavator’s automatic engine shutdown function after a ten minute
idle period, which saves fuel. Now he is starting to use LiDAT,
Liebherr’s data transmission and positioning system in order to
learn more about the operating and driving times, deceleration
and fuel consumption of the excavator.
“The first R 950 SME
within the Eurovia Group.”

Transport of excavated and prepared material via conveyor belts.
The Liebherr backhoe bucket with a digging volume of
2.75 m³ was equipped with pointed teeth, which are superbly
well suited to the material.

“This dealer really has orientated itself toward our requirements.
If necessary, he calls in the evening after production has stopped,”
says Alexandre Favin, who also stresses the responsiveness of
the dealer. When excavator driver Jean-François Méry explained
that it is sometimes difficult to dig into the piles of material, Fabien
Denis proposed trying out more pointed teeth. “It’s easier with
the more pointed teeth,” comments Jean-Francois Mery. “We
have now fitted the backhoe bucket with five teeth of this form,”
explains Alexandre Favin.
