French crane service provider Ponticelli Frères has lifted a blower weighing approximately two tonnes onto the roof of the Montparnasse Station in Paris for its customer Axima.

For the lift Ponticelli Frères used its Terex AC 500-2 crane. According to Terex, the jobsite posed numerous challenges including: restricted space; the need to navigate city centre traffic; and a small window of time in which work could be carried out.

Prior to the lift Ponticelli Frères conducted extensive preparation. “We had lots of discussions with SNCF, Paris public transportation operator RATP, the department responsible for motor vehicles, and the city council in order to agree on the best way to get the crane to the work site and operate it there,” explained Louis-Arthur de Quatrebarbes, Ponticelli project manager for the company’s Assembly and Lifts unit.

Bus lanes and pedestrian walkways around the work site were temporarily rerouted. The restricted working area at the jobsite meant that all details of the lift had to be planned and an in-depth site map for components and loads was drawn up.

“We drove the AC 500-2 from our branch office in Vitry-sur-Seine, south of Paris, to the Montparnasse site within an hour on Sunday night,” said Quatrebarbes. “To save time, we used two teams with seven assembly technicians in order to set the crane up. A total of 12 trucks were used to transport all attachments and crane accessories, as well as the required 180-tonne counterweight.”

At the site the AC 500-2 was configured to lift loads of up to five tonnes at a radius of 96 metres to a maximum height of 85 metres. This was achieved using a WIHI-SSL configuration with a luffing fly jib and full counterweight.

To prepare the crane for the lift, the assembly teams also used a 100-tonne assist crane. It took them two days and a night shift to get the Terex AC 500-2 ready.

For the lifts a team of 12 people were used. In order to utilise the crane’s maximum capacity the smallest hook block possible was chosen. Ponticelli checked with Terex to ensure that a small hook with two-part reeving could be used instead of the standard hook with three-part reeving. “Once we got the green light from Terex Cranes, we were able to use the AC 500-2 and forego using a bigger crane,” commented Quatrebarbes. Ponticelli Frères complete the job in a week, as scheduled.
