in operations,” explains Beckers. “Fuel consumption and material
movement have been recorded and compared. This has enabled
us to obtain figures for fuel consumption per ton of material
quarried. With Liebherr machines, we can save 1.1 to 1.3 up to
sometimes even 1.6 gallons of diesel per hour. At 15,000
operating hours per year that makes several thousand US $.”

Fuel consumption is not the only criterion that is taken into
account for procurements. Service also plays an important role
as it has a decisive influence on machine availability. “Machines
that are not running immediately run up immense losses. That’s
something we can’t afford, and that’s why we use Liebherr
machines,” continues Beckers. “With the Nagel Group, we have
a truly competent and reliable service partner. Whenever we have
a technical question, we always get an answer straight away.”
Despite the fact that operations are heavily trimmed towards
efficiency, expense is not spared on the machines themselves.
“Our drivers work on the machines for up to 10 hours and must
be in top form at all times. That means they get the equipment
they need to make work easier. Comfort seats, climate control
and auxiliary heating, for example, are features on all our machines,”
says Beckers. “This makes work easier and, not least of all, it
is a question of safety.”
