rising temperatures would make helicopter operations impossible. In addition, flights were also affected by the altitude-related limitation of the load capacity to 3.2 tonnes so efficiency was key. BKL transported the crane parts to the place of departure


using several trucks with shortened trailers to safely navigate the narrow mountain roads. At the helicopter departure point BKL prepared the crane


components so that they could be quickly attached to the helicopter. To further facilitate efficient assembly BKL configured the crane without a cabin and removed other non-essential components to save weight and helicopter hours. It also weighed and marked each component in advance to


ensure a smooth process. At the construction site BKL’s service engineers secured the


crossbase on a pre-concreted surface to save heavy base ballast. To enable the tower sections to be flown in closely timed sets, they were first set up and partially bolted together. The final bolting was done in the flight breaks. Despite adverse weather conditions and a flight break of


several hours due to dense fog BKL completed the crane assembly in just 15 flights over one day. A YouTube video of the job can be seen here: https://youtu.be/8gafDZmvtuI
