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 penetrationand 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.

The right tooth
for every application
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.
Standard tooth
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.).

(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.
