Liebherr offers a wide range of additional functions and
equipment for generation IV – crawler loaders.
Particularly at waste dumps and waste transfer stations,
the crawler loader becomes indispensable due to its universal operation possibilities. The crawler loader can be
used to shove and condense garbage, and also to load,
sort, break, and reduce material into smaller pieces. In
addition, the crawler loader can be used for many earthmoving purposes at landfi lls, such as refi lling, grading,
carrying material off, and building dams. Even trucks that
get stuck can easily be towed out by a crawler loader.
The Liebherr crawler loader can be individually confi gured with many additional options according to the
purpose of its use, which enables us to provide each
customer with the ideal machine.
The specifi c components were developed especially for
landfi ll usage and guarantee a high life expectancy of the
base machine even under diffi cult circumstances, such
as aggressive material or heavy pollution. The generation
IV- Liebherr crawler dozers guarantee maximum quality
since they combine the functions of power, reliability,
effi ciency and comfort all in one machine.

Landfi ll equipment volume
Sealed ventilation slots
in operator’s cab
The front, rear, left and right ventilation slots of the cab are fi tted with
seals to ensure no dirt gets into the
recesses, thus reducing the number
of times cleaning is required.
Lift cylinder covers
The lift cylinders are enclosed
by covers to protect from dirt
and contamination.
Exhaust manifold isolation
The exhaust system is shrouded to
prevent the ignition of dust or waste
particles around the engine, as well
as fl ying sparks.
External air supply alternator
The alternator is provided with pure
cooling air by a hose to guarantee
best cooling results.

Radiator guard
A sturdy lateral swivel radiator guard with 45°angled ribs
and a standard skirting protection ensure ideal protection for the rear side and the radiator.

Filler guard
A solid guard reduces the risk of damaging the
diesel fi ller neck. It can be fi tted in combination
with a tank guard.
Landfi ll equipment volume
Air pre-cleaner engine
The centrifugal force of the precleaner removes dust particles
before they reach the fi lter. Especially in dust-intensive use,
e.g. at landfi lls, the pre-cleaner
ensures pure air is drawn in. The
system guarantees a longer life
of the fi lter cartridge, reduces
wear and increases the engine’s
life expectancy.
Reversible fan
The reversible fan is benefi cial
in dirt-intense usage due to its
self-cleansing abilities. By reversing the air stream the fan blows
dirt particles off, which increases
the cooling power and reduces
cleaning intervals.
Fine perforated plates
The fi ne perforated plates surrounding the engine prevent intrusion of
dirt particles. Sucked-in material is
blown off by the reversible fan.
Hydraulic oil indicator
The indicator allows monitoring
of the hydraulic oil to prevent
overheating.

Front attachments
Strong steel cutter and wear plates provide the necessary longer life guarantee, since they need to resist extremely
corrosive and aggressive material at landfi lls. No matter if used for loading, grading or pushing, all the bucket
versions provide excellent fi lling and penetration attributes.
Standard bucket
The standard bucket is the
most frequently used front
end attachment for crawler
loaders. The shape and
capacity of the bucket has
been designed in a way that
makes it usable for any kind
of material. The standard
bucket is available with an
optional trash rack, which
increases the loading capacity.
Multi purpose bucket
The multi purpose bucket
is a high-performance
multifunctional tool. It can
be used for loading, shoving, grabbing, as well as
grading. The bucket allows
bulky material to be easily
picked up and transported
securely. An optional trash
rack and tilt cylinder protection guard are also available.
Waste handling bucket
The waste handling bucket offers a higher fi lling capacity
and is therefore best suited for material of low weight or
low density. Depending on its specifi c use it is available
with or without teeth.

Bolt-on cutting edges
don’t have as much penetration power, but are
suitable for stockpiling
and clearing tasks.

The radial 3-shank ripper provides excellent penetration
and ripping behaviour. At landfi lls, it is mainly used for
loosening the overburden before it is removed to make
room for more waste.

Landfi ll equipment options
Tank guard
A 10mm thick protection surrounds
the hydraulic tank and tread-plate
to avoid damage from outside. The
smooth surface prevents objects
from getting entangled.
Track shoes with trapezoidal holes
The trapezoidal holes provide better dispersal of material adhering to
bushings and track shoes.
Rear striker bar
Bars at the rear side optimize the
track’s self-cleaning abilities. In addition, they prevent material from
getting tangled in the chains and
being dragged over the track.
Lifting cylinder guard
The hydraulic pipes of both lifting
cylinders are protected by robust
covers.
Sprocket segments
with recesses
The segment recesses improve
the bushings’ running abilities, as
material on the wearing surface is
automatically pressed through the
lateral openings.
Tilt cylinder guard
The tilt cylinder is protected by a
robust cover that is attached to the
cylinder’s piston.
Protective grille
The windshield, made of safety
glass, is provided with extra protection from falling objects by a
strong metal grille.
