High voltage pylon crane lifting operation

“The heaviest parts weighed in at some 4.5 tonnes,” says Roger Beck from Bau-Trans’ Vaduz (Liechtenstein) location. Considering the fact that these steel components had to be lifted into place to the millimetre at a height of up to 68 metres it becomes clear what challenges the crane operator faced in order to not impede the fitters’ work. Making matters worse, the construction site was located between a railway line and the motorway. “We could only perform our crane operations in times of no wind,” Beck adds. Otherwise the load would have started to swing. This could have had serious consequences. “We used an LTM 1130 mobile crane with a 60-metre telescope boom and a 10.8-metre hydraulically adjustable latticed pylon point,” Beck illustrates the technical details.

Thanks to excellent communication between the crane operator and the fitters, the team managed to erect two power poles 58 and 68 metres tall and to remove an obsolete one, all within a single week. The construction of a new transformer station and subsequent line re-routing had made the construction necessary.
