The Liebherr
Working Tools
Tool-System for a
variety of jobs
Liebherr working tools for excavators were designed as problem solvers for the most varied
applications. The carefully balanced program ranges from standard buckets for digging and
loading of loosened material to buckets for heavy-duty jobs in the mining industry with extreme
break-out forces and high wear and tear. Equipped with effective, to the relating ground matching teeth the Liebherr digging tools provide a maximum productivity and longevity.
Performance
Liebherr digging tools are particularly productive excavator components at
the very latest technological level. Special bucket shapes, permit maximum
transmission of power, provide the best penetration- and outstanding digging characteristics. Optimized bucket capacities and improved heap-cones
provide the best turn-over performance.
Reliability
Liebherr digging tools are in-house designed and manufactured. Specific
material selection, specialized heat treatment and lowest machining tolerances are utilized in order to achieve the especially toughness and the high
longevity. The convincing result: outstanding dependability under the most
severe job conditions.
Comfort
The careful and precise calibration of bucket shape and tooth selection
provides the ideal digging tool for each job. The proven and reliable quickchange system LIKUFIX permits the split-second, safe exchange of mechanical and hydraulic attaching tools by the press of a button from the cab.
LIKUFIX attaching tools also work on hydraulic excavators with Liebherr
quick change adapters without LIKUFIX - that means full flexibility and high
comfort in every situation.
Efficiency
Liebherr digging tools provide a maximum of profitability. The Liebherr quick
change systems increase productivity especially in applications with varying
attaching tools. The 24/7 availability of wear parts and the easy exchange
procedure safe time and money as well. Because of the modular design, the
change systems and tools are very suitable for future tasks.

Bucket options
Whether loose dirt, abrasive material or hard rock – quality and effectiveness of every
excavator job are affected by the targeted selection of the suitable bucket. Therefore,
Liebherr has designed a wide range of bucket options, which are especially suitable for an
applicable job due to the shape, material selection and technical fittings. Practical experience and continued attention to product development assure that Liebherr buckets are
always state-of-the-art technology.
Backhoe bucket
with teeth
Suitable for digging up hard ground
Backhoe bucket
with clip-on cutting edge
A backhoe bucket with teeth that can be
equipped with a cutter if required
Backhoe bucket
with cutting edge
Optimum penetration due to low digging resistance
Backhoe bucket with univer-
sal mounting bracket
Suitable for any rapid-change systems
HD-backhoe bucket
Suitable for very abrasive materials due to wear
protection and side reinforcement
Backhoe bucket with
limited digging depth
If the rapid-change slot of a backhoe bucket is
wider than the backhoe bucket itself, this limits the
digging depth.
For cases such as this Liebherr offers backhoe
buckets with an extended basic shape. This
increases the maximum digging depth.

The right tooth
for every appl ication
The economic use of a hydraulic excavator is only possible if the tooth shape
matches the relating application. Liebherr offers a broad tooth program with tooth
shapes for every task.
Liebherr Uni tooth system:
A 910 Compact (A 309) - A 918 (A 900) / R 918 - R 920
(technical data on page 42)
Due to its low overall heigth and the slim, self-sharpening tooth shape the
Liebherr U-system stands for best diggning behavior at lowest penetration
resistance. Highly wear-resistant steel provides familiar reliability under hard
conditions, which has already stood the test on wheel loaders. The lateral rolled pin
fastening allows a simple and safe change of teeth.
Features:
symetric caps with cut-out at the front, self
sharpening, reversible.
Application:
for friable and medium-weight friable soils
(loamy sand, gravel, soft brown coal, soft/
medium clay etc.).
Features:
Cap with high share of material for long service
life in wear-intensive applications.
Application:
for extremely abrasive soils (granite, basalt,
sandstone, rocks with high share of silica etc.).
Pointed toothHD-toothStandard tooth
Features:
Pointed tooth for good penetration, reversible.
Application:
for very hard and frozen soil, non-friable rock
(limestone, shale, brown coal, mining of wall
gravel etc.).
10
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.
C-tooth
Features:
The conical shape allows for very good penetration 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.
R-tooth
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.
CL-tooth
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.
P-tooth
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
CR-tooth
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.
PF-tooth
Features:
Fork tip with excellent penetration properties in
extremely compact soils. Can be fitted as a supplement 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
Shrouds
Reduces exposure of the bucket to impacts
and abrasion, extending ist wear life. Allows
you to carry more material and to increase penetration, thereby improving productivity of the
machine.
