![]() The powerful LR 1800-1.0 crawler crane has an 800 metric tonne lifting capacity and comes equipped with a luffing jib and derrick system – useful in power plant construction and petrochemical applications. Liebherr will also be displaying its LTM 1230-5.1 mobile crane and LR 1800-1.0 crawler crane at the show for the first time after their recent launch, with the latter vehicle being available for delivery immediately after the event. Taking place at the Messe München in Munich, Germany, on April 8-14, the industrial vehicle trade show will be the first opportunity to get a glimpse of the two new mobile cranes. His succinct conclusion after the first job with the new LR 1700-1.Liebherr will premiere two mobile cranes catering to differing operator needs at Bauma 2019.Ī new eight-axle crane will provide superior performance, while a five-axle model to be unveiled at the show will suit customers seeking value for money and flexibility in application use. “The crane can be operated very smoothly and effectively even with heavy loads at height,” reports Christoph Bergmaier, who takes turns with Stephan Dickel at the controls of the Liebherr crane. Even the heaviest loads on the hook, the 72-tonne nacelle and the three-tonne drive train, were handled without any problems. For the assembly of the wind turbine components, the two drivers then steered their crawler crane close to the tower – with a radius of 26 metres, all components were assembled. ![]() The continuously adjustable V-frame ballast radius enabled the blue-painted Hofmann crane to operate in relatively little space on the construction site near Paderborn – even during the slewing process. A procedure taking about ten minutes with just four bolts – and a total of 375 tonnes of counterweight is already hanging from the derrick boom. The large ballast pallet is only docked for erecting or taking down the lattice boom – which, by the way, can be erected to an impressive length of 198 metres. “The VarioTray divisible derrick ballast and V-Frame allow us to work with 60 tonnes of derrick ballast during the entire assembly of the turbine – so we don’t have to carry out any time-consuming ballasting”, Christoph Bergmaier is pleased to say. Hofmann’s new LR 1700-1.0 comes with all the innovations of Liebherr’s crawler crane development from recent years – and has other time-saving features too. This is an invaluable advantage for customers and end users, because normally the wind stops at nine metres per second. With only a minimally reduced maximum load, this value even increases to 13.4 metres per second. Liebherr allows wind speeds of 11.2 metres per second for the LR 1700-1.0 – as for all current LR crane types with special wind power equipment configurations. The greater wind tolerance of this boom configuration can save the crane and assembly teams on site many a stoppage due to excessive wind. “The H-Boom lets us operate under higher wind loads”, explains crane operator Christoph Bergmaier. This includes nine lattice boom sections of the somewhat wider H-Version (“Heavy”), each twelve metres long. The heaviest components were the nacelle and drive train with gross loads of 72 and 75 tonnes.Īt the “Holzhausen” wind farm, about 20 kilometres east of Paderborn, the LR 1700-1.0 was equipped with a 165-metre-long main boom. ![]() The LR 1700-1.0 masterfully dealt with the prefabricated 96-metre high concrete tower for the turbine with a hub height of 164 metres. The local crane company Hofmann Kran- Vermietung GmbH & Co KG, a subsidiary of the Bracht Group, used the crane to erect a Nordex Delta 4000 wind turbine. ![]() The 700-tonne crawler crane recently fulfilled the high expectations placed on it at its première in a wind farm near Paderborn. ![]() The first jobs deploying the state-of-the-art powerhouse from Ehingen have been completed with tremendous success. The new Liebherr LR 1700-1.0 crawler crane is gaining momentum. The first of these are two machines – recently delivered to the German crane companies Hofmann (Paderborn) and Wasel (Bergheim near Cologne). With the LR 1700-1.0, the Liebherr factory in Ehingen is bringing a worthy successor to the successful LR 1600/2 and the result of its latest developments in innovative crawler crane technology onto the market.Ī highly efficient powerhouse is coming to construction sites near you. ![]()
