Wolff towers in helicopter lift
By Laura Hatton16 September 2013
Three Wolff tower cranes have been assembled using a helicopter at an Alpine construction site in Ischgl, Austria.
The WK 5015s were assembled by Silvrettaseilbahn to help with the expansion of a ski resort in the Alps, 2,812 metres above sea level.
To accommodate the difficult site conditions, the components of the saddle jib tower cranes were transported by truck to Fimbatal, 1,950 m above sea level. They were then transported and assembled into position piece by piece using a heavy lift helicopter owned by Heliswiss International.
Work for the towers included erecting two pylons, 64 and 90 metres tall, for a new aerial tramway, a company spokesperson said.
Engineer Markus Walser, on the Silvrettaseilbahn board, said, “Despite being a first, the tight schedule and the complex conditions, Wolffkran Austria coped with the assembly professionally and without any problem.”
