Potain Tower Cranes erecting third tallest Building in France

LYON/FRANCE, October 13, 2014 - Two Potain tower cranes are building an ambitious commercial development in the heart of Lyon, France. The 200 m tall Tour Incity will be the tallest building in the city and the third tallest in France. The Potain cranes are working 14 hours a day for 30 months to build one floor per week at the congested job site.
The demanding schedule is the result of the building’s inner-city location. Flanked by a busy road, a school and a shopping mall, work must adhere to a strict schedule to limit disruption to the local area.

The 16 t capacity Potain MD 550 and 12 t capacity MDT 222 tower cranes, which are owned by the project’s main contractor Bouygues, were chosen for the project.

The Potain cranes at Tour Incity were erected in 2013. They are lifting general construction materials in loads of up to 16 t. Both cranes are climbing at a rate of 15 m per month and set to reach final working heights of 280 m.

The cranes’ exact position and jib lengths were carefully planned to ensure maximum coverage of the job site, yet minimal disruption to the busy streets below. As a result, one of the Potain cranes, the MDT 222, is climbing internally, adding to the technical challenge of the project, as Alexandre Chanteclair, EMEA product manager at Potain, explains.

The Potain MDT 222 is erected with a specially-adapted floor climbing system where a unique frame is attached to the building’s concrete core. This allows the crane to reach its final working height while maintaining its strength and stability. The MD 550 is installed with Potain’s external anchorage system where several frames fix the mast to the outside of the building.
