French contractor Bouygues has put two Potain tower cranes on site to build the Tour Incity commercial development in Lyon, France.

The 200 metre building is the third tallest building in France. It will offer 44,000 square metres of office space and four restaurants.

On site is a 16 tonne capacity Potain MD 550 and a 12 tonne capacity MDT 222 tower crane. Work for the cranes includes lifting general construction materials weighing up to 16 tonnes. The cranes are scheduled to be on site for 30 months and will be working 14 hours a day. The schedule is to limit disruption to the local area, a spokesperson said.

Challenges on site include working by a busy road, a school and a shopping centre. To help reduce disruption and to ensure maximum coverage of the job site, the MDT 222, is climbing internally and has been erected with a specially adapted floor climbing system. The system includes a frame attached to the buildings core, which allows the crane to reach its final working height while maintaining its strength and stability, a spokesperson said.

The MD 550 is installed with Potain’s external anchorage system and has been configured with a 60 m jib. The Potain MDT 222 has been fitted with a 30 m jib. Both cranes are climbing at a rate of 15 m per month and are set to reach final working heights of 280 m, a spokesperson added.

Julian Bargues, Bouygues job site manager, said, “We are absolutely convinced that the Potain cranes will deliver to the high standards and strict schedule we demand. Working in such a tight space means we need very precise load control and smooth movement, two things we know Potain cranes are ideal.”

Alexandre Chanteclair, Potain EMEA product manager, said, “Big projects need smart and efficient solutions. Our Lift Solutions team worked closely with Bouygues to design the perfect lifting solution. Erecting the MDT 222 internally minimizes the two cranes’ footprints on the job site, while giving the crane the optimum capacity over the maximum area of the job site. It also ensures the cranes can work at a good pace without causing problems for the local area.”
