1 The Liebherr Working Tools Everything from one source

2 Tool-System for a variety of 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. Productivity 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. Dependability 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 quick-change 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. Profitability 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. 2

4 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 Backhoe bucket with cutting edge HD-backhoe bucket Backhoe bucket with clip-on cutting edge Backhoe bucket with universal mounting bracket Backhoe bucket with limited digging depth * If the quick change adapter mounting bracket is wider than the backhoe bucket itself, the digging depth is limited. For such instances Liebherr offers backhoe buckets with a stretched body. This increases the digging depth. 4

26 LIKUFIX, Tool-Control and Tool-Management LIKUFIX LIKUFIX is a hydraulic coupler combined with an automatic hydraulic coupling system, which was developed by Liebherr. LIKUFIX enables hydraulic excavators a quick and safe change of mechanical and hydraulic attaching tools from the cab. Tool-Control Tool-Control is an additional electro-hydraulic function, which makes working with hydraulic working tools very comfortable: up to 10 combinations of oil flow and pressure can be programmed under the tool designation and selected directly from the display. The operator simply selects with Tool-Control with the push of a button the desired hydraulic tool without an elaborate new adjustment with a tool change. Tool-Management Tool-Management allows the automatic tool recognition through the hydraulic excavator. With the reading device on the LIKUFIX block the data stored in the chip of the working tool is being read and transmitted to the operator s cab. With the press of a button the operator confirms the takeover of data and therefore the automatic setting of oil flow and oil pressure. Aside from this data oil grade and working hours are being stored on the chip as well. The technical advantages Fully automatic play compensation Tight connection between the hydraulic circuits thanks to the hydro-mechanical compensation system More than 25 years experience in fully-automatic coupling systems Reliable system with long service life Not only attachable to Liebherr excavators The comfort advantage Reliable hydraulic connection free of oil leaks Low operating and maintenance costs Add-on parts can be changed from the cab The economic advantage Hydraulic add-on parts changed in a matter of seconds meaning better machine utilisation with different applications on the same unit Major time savings in comparison with hydraulic-hose changes Low operating and maintenance costs with maximum productivity Moving to the unit Coupling into the unit Connected to the unit, mechanically and hydraulically 26
