We started at the job site with a trolley jib crane to do some prefabrications where a luffing jib crane is not necessarily needed. Then the upper part of this first crane was dismantled, the tower was heightened and the WT 205L e.tronic was erected on the top. The WT 205L e.tronic is erected on foundation anchors and has a freestanding tower height of 112.95m. Its jib length is 42 m, so heights under hook up to 154.95 m can be reached. ?“The WT 205L e.tronic is placed in the middle of the new cooling tower to build it. The assembly could have been executed with any other ‘normal’ mobile crane. However, we decided to use the GTK 1100 because when the cooling tower is built we want to dismantle the WT 205L e.tronic with that crane standing inside the cooling tower.? “Therefore it was a good chance to test the GTK 1100. One advantage was that the GTK was tested at maximum height and so there is no need to climb up the WT 205L e.tronic later. ?“A disadvantage of using the GTK 1100 is that it is much more expensive than using a ‘normal’ big mobile crane. As long as the prices do not rise very much, we would consider using it again.”?Jochen Wiesbauer says that the Wilbert crew working to erect the tower crane reported that the crane was very stable in the wind: “They said there was no movement on the upper structure.”
