The Liebherr Working Tools

2

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.

PerformanceLiebherr 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.

ReliabilityLiebherr 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 provides the ideal digging tool for each job. The proven and reliable quick-change system LIKUFIX permits the split-second, safe exchange of me-chanical 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.

EfficiencyLiebherr 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.

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.

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.

Pointed toothHD-toothStandard tooth

Liebherr Z tooth system: A 918 (A 900) / R 920 - R 980 SME(technical data on page 38)

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.

Tilt rotators have today become an essential part of civil engineering. Thanks to the flexible use of the backhoe bucket, the unproductive repositioning of the hydraulic excavator during work can be substantially reduced, and the productivity of the machine is increased.Lieberr tilt rotators have a slewing angle of 2 x 50º and can rotate infinitely through 360º. The integrated rotating cylinder itself, which is protected and located horizontally, has no projecting parts even at maximum rotating angle, which could otherwise be damaged when working in confined spaces. This ensures that servicing costs are kept low, and makes Liebherr tilt rotators the ideal tool for working in lining operations or when close to building structures. In conjunction with the ergonomic Liebherr proportional control system, the tilt rotator can be put to use rapidly, with fine sensitivity, and with maximum precision, which helps achieve high productivity for the hydraulic excavator.The preparation of complex excavation contours and the exposing of existing structural elements such as drain shafts, pipes, etc. can be carried out extremely rapidly with Liebherr tilt rotators. Tedious and sometime dangerous shaft excavation by hand can be reduced to a minimum, and personnel can move on to the next tasks to be dealt with.It is recommended that Liebherr tilt rotators be fitted on the upper side with the Likufix quick coupling system from Liebherr. In this way, the tilt rotator is only attached when it is actually needed, which reduces fuel consumption, increases the service life of the tilt rotator, and allows for the maximum load capacity of the hydraulic excavator to be fully exploited during hoisting operations. In traditional earthmoving situations, taking off the tilt rotator allows for the largest possible backhoe bucket to be fitted, in order to achieve high handling performance with low fuel consumption.Together with Liebherr wheel and crawler excavators, Liebherr tilt rotators attain maximum productivity, reliability, and safety on the construction site.

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.

Functionality

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.

Applications• Sewage construction• Pipe-laying jobs• Highway construction• Development

Features• For pipes up to a length of 3.50 m• Pipes with outer diameter of 450 up to 800 mm installable• Pipes up to 230 mm outer diameter can be installed as an option• Curb weight appr. 1,400 kg• Lift capacity: approx. 1,500 kg• Solid construction• 360° endlessly turnable• Adapter for plastic pipes deliverable• With LIKUFIX or universal adapter• Pipe feed: manual changeover on unit, alternatively from the operator’s cab• Suitable for excavators starting A 918 (A900) / R 918 (R 900)

Benefits• Excellent pipe-laying performance• Operation in accordance with existing standards• Adjustable insertion pressure, thus less pipe damages• Simple and quick unloading of delivered pipes• Excellent operational safety, no person permanently in the direct danger zone• Minimum 10% productivity increase• Pipes can be layed from any direction and independent from any incline• Space saving in confined spaces: the Liebherr pipe laying unit hardly needs

more space than the pipe itself
