German mobile crane company H & S Autokrane used the Challenger at the facilities of Kassel-based Kali- und Salzwerke to install and remove pipelines.

The three-axle, 55t Challenger 3160 features a 50m boom system which met requirements of the project including hoisting pipelines and steel elements 42m for assembly into an existing structure, and hoisting with a wide radius for moving underneath pipeline bridges.

The crane overcame various complications during the project including navigating a narrow approach, which at some points allowed a width of 2.6m and a height of 3.6m. Drains passing underneath the workspace limited the weight for the job to 40t, as well as restricting the use of half of the outrigger extension for parts of the project while still requiring the full counterweight.

Jens Hartung, field crew member at Hesse-based H & S Autokrane, said: "We were able to master even this task with our Challenger.
"To work here, a crane needs to be really small when it pulls in, and large with a long boom in the structures. Moreover, it needs to be able to lift heavy loads. The Challenger 3160 all terrain crane comes the closest to fulfilling this ideal."
