The right tooth
for every appl ication
Liebherr Z tooth system: A 918 (A 900) / R 920 - R 980 SME
(technical data on page 43)
The optimized tooth design leads to efficiency increase of the Liebherr Z-system on the jobsite. The low digging resistance,
the self-sharpening tooth shape or the simple hammer-free change of teeth speak for the Liebherr Z-system. The teeth are
made out of high-strength steel which distinguishes itself through highest wear resistance and long service life.

Features:
The conical shape allows for very good penetra-
tion capacity in non-cohesive soils.
Application:
Friable soils and weak non-cohesive soils, such
as loose, loamy sand, fine to medium gravels,
and wet or soft clay.
Features:
Narrow cutting width and high wear volume for
high penetrating forces and extended life.
Application:
Hard-to-penetrate ground, particularly abrasive
materials, rock, i. e. limestone, shale, very hard
clay, lignite.
Features:
Long-drawn pointed shape with sharp cutting
edge for very good penetration properties.
Application:
Medium-weight friable and non-cohesive soil
types up to soils with medium plasticity, such as
hard, loamy sand, medium-hard clay, and fine to
medium gravel.
Features:
The long drawn tip allows for good penetration
in broken ground and debris. The wide, thick
sole of the tooth provides for a long service life
even under intensive wear conditions.
Application:
Abrasive soils and rocks, such as granite, basalt,
and sandstone. Predominantly in combination
with bottom dump bucket operations.
Features:
Pointed tooth with good penetration properties
even in hard stone and rocky applications.
Application:
Very hard, frozen ground, non-friable rock such
as compacted, unweathered clay schist
Features:
Fork tip with excellent penetration properties in
extremely compact soils. Can be fitted as a sup-
plement to the P-tips on the bucket corners in
order to retain the inclination angle.
Application:
Very hard, frozen ground, non-friable rock such
as compacted, non-weathered clay schist,
heavy ores with medium and weak cleavage,
slag heaps at steel plants.

Wearing cap
Wearing caps are designed to increase lifetimes
of adapters in extreme abrasive applications For precise jobs where the terrain surface
must be left smooth For tougher applications
Reduces exposure of the bucket to impacts
and abrasion, extending ist wear life. Allows
you to carry more material and to increase pe-
netration, thereby improving productivity of the
machine.
