The Liebherr mobile crane proved its usefulness by completing a delicate job in an extremely constricted space in a historic city.

Combining hardware with art
The repair work was carried out over four night shifts. Damaged fabric sections weighing between 200 and 400 kilograms were lifted and reattached in collaboration with rope access technicians. As the construction site was located in a wind corridor along the River Seine, weather conditions were continuously monitored. Communication between the crane operator and the rope access technicians took place continuously via radio.
Before work began, the team performed site inspections, load calculations, and collision analyses of the surrounding buildings. A 360-degree test subsequently confirmed the planned crane positioning.
For Ponticelli, the project was far more than a conventional lifting operation. “We are proud to have been part of this work of art. To quote JR: ‘The installation of the artwork is part of the artwork’ — and so is the crane,” explains Louis-Arthur de Quatrebarbes. “The visually striking deployment of the MK crane created a magical moment.”
With its successful deployment on the Pont-Neuf, the Liebherr MK 88-4.1 mobile construction crane demonstrated its strengths in demanding inner-city projects. Where heritage conservation, confined spaces, and a high level of precision come together, the mobile construction crane offers the right combination of reach, compactness, and flexibility.
