Scholl opted for the GTK1100 for the lift after looking at a number of other lifting options, including using a large all terrain crane equipped with a full luffing jib and a man basket. This option was discounted after local government officials refused to approve the lift plan.
A second option involved using a large crawler or all terrain crane equipped with a luffing jib, but this was also ruled out due to space restrictions on the site preventing rigging operations.
In the end, the GTK1100, owned by Wiesbauer, was used to carry out the dismantling. It was equipped with a Modulift lifting beam attached to the hook block. This was attached at four fixing points to the chimney top, allowing the crane to lift 47.2t, including the weight of the rigging, at 100m.
“We looked at other options, in addition to the GTK, but ruled them out because the logistics made their use impossible,” said Jürgen Jensen, Scholl’s project manager for the job.
“And, it was faster and less costly than using alternative lifting systems.”
