Tool-System for a variety of jobsLiebherr 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 match-ing teeth the Liebherr digging tools provide a maximum productivity and longevity.
ProductivityLiebherr 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 dig-ging characteristics. Optimized bucket capacities and improved heap-cones provide the best turn-over performance.
DependabilityLiebherr digging tools are in-house designed and manufactured. Specific material selection, specialized heat treatment and lowest machining toler-ances are utilized in order to achieve the especially toughness and the high longevity. The convincing result: outstanding dependability under the most severe job conditions.
ComfortThe careful and precise calibration of bucket shape and tooth selection pro-vides 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 at-taching tools also work on hydraulic excavators with Liebherr quick change adapters without LIKUFIX - that means full flexibility and high comfort in every situation.
ProfitabilityLiebherr 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 optionsWhether 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 experi-ence and continued attention to product development assure that Liebherr buckets are always state-of-the-art technology.

* 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.

The right tooth for every appl icationThe 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.
The Liebherr U-system (A 309 - A / R 900)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 resi-stance. 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.

The right tooth for every appl ication
The Liebherr Z-system (A / R 900 - R 974)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.

Hydraulic tilt-rotatorThe Liebherr hydraulic rotation drive increases the utilization of an excavator many times. Even under severe conditions, jobs are quickly and effectively accomplished with this modu-lar adapter. The horizontally positioned tilt cylinder is well protected even at the maximum tilt angle and has no extruding parts. Its particular features such as infinite rotation in both directions, tilting at 2 x 50° and the quick-change system turn the hydraulic excavator into a multi-purpose machine. In connection with Likufix the possibility exists to completely lay aside the swing rotator with working tools and to pick up other tools.

ClamshellsNext to the backhoe bucket, the clamshell is one of the most important digging tools in the utility business. The clamshell selection is based on the ground condition, the specific mate-rial weight and the required production performance. The selection of the entire clamshell attachment is significant in order to determine the required digging depth.

LIKUFIX, Tool-Control and Tool-ManagementLIKUFIXLIKUFIX 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-ControlTool-Control is an additional electro-hydraulic function, which makes working with hydrau-lic 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 opera-tor 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-ManagementTool-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.

Pipe-laying toolThe pipe-layer developed by Liebherr enables significant productivity increase when laying sewage pipes. The pipe is picked up, positioned at the end of a pipe already in place, aligned and inserted into the previously installed pipe in accordance with existing standards using a horizontal ram. The pipe-layer enables quick and efficient installation of pipes of various lengths, diameters, weights, materials and nominal sizes. Thanks to this system, operational safety on pipe-laying sites is raised considerably, since no one is forced to remain in the dan-ger area.

Class 1: Top soilTop soil is the most upper layer of the ground, which contains besides in-organic matters, e.g. gravel-, sand-, silt- and clay mixes as well as humus and organic organisms.
Class 2: Fluid materialMaterial of fluid or mushy composition from which water is not easily drained.
Class 3: Easy diggable materialNon-cohesive to semi-cohesive sand, gravel and sand-gravel mixture with upto15weight-%additionofsiltandclay(grainsizelessthan0.06mm)andwithmaximumof30%weightofrocksoflargerthan63mmgrainsizeup to 0.01 m3 volume. Organic material with low water content (e.g. com-pacted peat).
Class 4: Medium diggable materialMixtureofsand,gravel,siltandclaywithashareofmorethan15weight-%,grain sizes smaller than 0.06 mm. Cohesive material of light to medium malleability, which are soft to semi-firm depending on the water content andwithnomorethan30weight-%ofrockslargerthan63mmgrainsizeup to 0.01 m3 volume.

Non-cohesive and cohesivematerialwithnomorethan30weight-%rockslargerthan0.01m3 volume. Particularly plastic clay, soft to medium hard depending on the water content.
Class 6: Easy to penetrate rock and comparable materialRock, which has an internal, mineral bund cohesion, but severely frac-tured, brittle, crumbly, slated, soft or weathered as well as comparably compact or solidified non-cohesive and cohesive material with more than 30weight-%rocksofmorethan0.01m3 to 0.10 m3 volume.
Class 7: Tough to penetrate rockRock, which has an internal, mineral bund cohesion and high structural density and is only slightly fractured or weathered. Highly compact, un-weathered clay slate, sedimentary rock layers, slag heaps at iron and steel works and similar. Rocks of larger than 0.10 m3 volume.
