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. A highly efficient powerhouse is coming to construction sites. The first of these are two machines – delivered recently to the German crane companies Hofmann (Paderborn) and Wasel (Bergheim near Cologne).

The new Liebherr LR 1700-1.0 crawler crane is gaining momentum. The first jobs deploying the state-of-the-art powerhouse from Ehingen have been completed with tremendous success. The 700-tonne crawler crane recently fulfilled the high expectations placed in it at its première in a wind farm near Paderborn. The local crane company Hofmann KranVermietung GmbH & Co KG, a subsidiary of the Bracht Group, used the crane to erect a Nordex Delta 4000 wind turbine. 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 heaviest components were the nacelle and drive train with gross loads of 72 and 75 tonnes.
