A helicopter was used to dismantle a Potain MDT 128 flat top tower crane from a 200 metre tall bridge pylon in Norway.
The crane was used to help construct the Hardanger Bridge, near Bergen, in south western Norway. The bridge is 1,310 m long and is one of the longest suspension bridges in the world.
Work for the 6 tonne capacity MDT 128 during the build included installing suspension cables and other lifting tasks. During the project the crane was working in wind speeds up to 217 km/h and temperatures as low as -40 degrees Celsius.
Crane rental company and Potain dealer Ajos from Denmark owns the crane. It was supplied to Scandinavian contractor MT Højgaard.
The Hardanger Bridge cost approximately €300 million (US $407 million).
