Liebherr L 550 - Manual (Page 3)

3 L 550
Solution
Since Baggerbetrieb Burkhardt GmbH already has eight
Liebherr wheel loaders, from the L 506 stereo loader to the L 544
mid-range machine, and is very happy with their performance,
the company has now added its first new generation large
machine, the L 550, to its fleet.
This machine is used for work on the very hard gravel wall.
To enable it to cope with the extreme forces required for this
work, the L 550 was fitted with a Liebherr earthmoving shovel
with teeth and a screw-on wear blade. The L 550 will also
be used to move material to the landfill site. For this task the
machine can use its permanent all-wheel drive system on all
four wheels and scores heavily with its self-.locking differential
from 0 to 45%. The sprightly and maneuverable machine has
also impressed René Burkhardt, manager and operator, on its
many trips to and from the crusher and screening system.
The hydrostatic travel drive provides another positive effect.
It enables the Liebherr diesel engine to be installed in a particular
position at the rear of the machine where it can also act as a
counter-ballast. This means that the vastly low net weight of
the machine provides a higher tipping load and greater stability.
In turn, this also means a reduction in fuel consumption which
is a low 9.5 liters per hour at Baggerbetrieb Burkhardt GmbH.
Furthermore, the Liebherr travel drive always uses hydraulic
braking even in the most adverse conditions at the company’s
site. The brakes therefore suffer practically zero wear. Liebherr
wheel loaders also score heavily in terms of service and
maintenance. This is because opening just one hood reveals
all the servicing points which can be reached easily and safely
from the ground. For operator Heiko Bauer there is simply no
alternative to the Liebherr L 550 wheel loader.
