Liebherr-Mietpartner GmbH has proven to be a reliable partner for KEMNA BAU on the D1 taxiway at Hamburg Airport. With the rental of six powerful machines, the work on the taxiway was completed reliably and to a high standard. In particular, the rapid availability of the machines and the reliability of Liebherr employees and machines were decisive factors for KEMNA BAU in choosing Liebherr. Once the old concrete surface of the taxiway had been milled away, the four mobile excavators and two crawler excavators came into play: First, hydraulic hammers were used to break out damaged concrete patches before the taxiway was excavated and an asphalt base layer was applied as part of the extensive renovation work. This created the basis for the SAMI layer (Stress Absorbing Membrane Interlayer) - a type of stress-relieving intermediate layer - before the asphalt surface course was finally installed. *A taxiway is a path for aircraft at an airport connecting runways with aprons, hangars, terminals and other facilities. They mostly have a hard surface such as asphalt or concrete, although smaller general aviation airports sometimes use gravel or grass. Wheeled excavators from Liebherr can be used for a wide range of applications: be it on the D1 taxiway at Hamburg Airport, in landscaping or on inner-city construction sites. In addition to the classic wheeled excavators, Liebherr offers a wide variety of models for the respective application with its compact variant. The powerful engine, high loads and fast work cycles as well as excellent mobility, make Liebherr wheeled excavators real all-rounders among construction machines. Thanks to innovative technologies, such as intelligent assistance systems, they enable more efficient and safer work processes. They also score points for their high level of economy and low fuel consumption, which reduces operating costs. The Liebherr R 920 Compact crawler excavator combines the characteristics of a standard crawler excavator, such as high performance and versatility, with the advantages of a compact wheeled excavator. The powerful diesel engine has a performance of 110 kW/ 150 hp and meets the requirements of exhaust emission stage V. With a low tail swing radius of just 1,850 mm, it can be used flexibly on inner-city construction sites. The compact dimensions of the R 920 Compact and its low operating mass of just 19 tonnes ensure high mobility and simple, fast transport between different operating locations. In addition to the powerful mobile and crawler excavators, Liebherr offers an extensive portfolio of suitable attachments for the respective application. For example, the Liebherr TR25 Tiltrotator was used during the renovation of the taxiway at Hamburg Airport. This machine optimally utilises its advantages thanks to the pivoting angle of 2 x 50° and 360° rotation when working at close range. Various backhoe and ditch-cleaning-buckets were also used to carry out the renovation work. Thanks to the fully automatic LIKUFIX quick coupling systems, a safe and quick replacement was possible directly from the operator's cab.
