Liebherr Cranes Help Complete Notre-Dame’s Resurrection

30-Second Takeaway

Liebherr mobile cranes played a critical role throughout the five-year reconstruction of Notre-Dame de Paris following the devastating 2019 fire. From early emergency operations to the final installation of the iconic 96-meter spire known as La Flèche, Liebherr cranes operated by French lifting specialists including Montagrues and Dartus Levage supported material handling, restoration of historic stonework, and the cathedral’s final reopening in late 2024.

From Catastrophe to Reconstruction

The fire of 15 April 2019 devastated Notre-Dame de Paris, destroying the entire medieval roof structure and causing the collapse of the crossing tower into the nave. Within hours, the catastrophe became a national and global symbol of cultural loss.

French President Emmanuel Macron declared the cathedral would be rebuilt within five years “Cinq ans!” a promise many initially considered impossible. What followed became one of the most complex heritage reconstruction efforts ever undertaken, mobilizing historians, structural engineers, artisans, foresters, and material scientists from across France

.

Among the essential tools enabling this effort were Liebherr mobile cranes, present on site from the earliest stabilization work through the final lifts that restored Notre-Dame’s skyline.

Early Crane Operations Saved Historic Statues

Just days before the fire, a Liebherr mobile construction crane from Foselev had removed the cathedral’s massive statues of the apostles and evangelists from the roof for planned restoration an action that ultimately saved them from destruction.

In December 2019, two Liebherr cranes operated by Montagrues arrived on Île de la Cité to erect the massive construction crane that would dominate the site for years. These early crane operations helped stabilize the structure and enable safe access to the damaged upper sections of the cathedral.

Dartus Levage Takes Over Mobile Crane Operations

Since spring 2022, French crane and transport specialist Dartus Levage has managed mobile crane operations at Notre-Dame. The company deployed multiple Liebherr cranes, including two LTM 1350-6.1 all-terrain cranes, whose long lattice masts stretched across the Paris skyline.

Operating at radii of up to 80 meters, these cranes transported:

• Timber beams for the reconstructed oak roof

• Stone blocks and architectural elements

• Gargoyles, cross flowers, and restored statues

• Scaffolding and specialized machinery

  
  

Their precision was essential on one of Europe’s most constrained construction sites, bordered by the Seine and surrounded by historic urban infrastructure.

Installing “La Flèche”

The most technically demanding lifts came with the reconstruction of the iconic crossing tower La Flèche. Rising 96 meters, the spire exceeds the height of Notre-Dame’s twin stone towers.

To assemble the upper sections, the northern LTM 1350-6.1 was equipped with a 78-meter luffing lattice jib, enabling lifts at extreme heights while maintaining precise control.

Operators worked in tightly coordinated shifts, often from early morning until late evening.

According to Victor Dartus, managing director of Dartus Levage, up to 14 employees were present on site during peak periods, including operators and chefs de manœuvre responsible for load control and site coordination.

Working in Extreme Constraints

“The spatial conditions here are an absolute challenge,” Dartus explained.“Crane parking areas are extremely limited, and reconfiguring cranes without disrupting ongoing restoration work requires meticulous planning.”

Four-axle 120-ton Liebherr mobile cranes proved especially valuable due to their ability to relocate quickly and operate with VarioBase® and VarioBallast®, allowing flexible setup even in confined areas around the cathedral.

Completion and Reopening

By November 2024, Liebherr cranes had completed their final lifts. Just days later, Notre-Dame reopened in a ceremony attended by international dignitaries marking the conclusion of one of the most ambitious heritage reconstruction projects in modern history.

Frequently Asked Questions

Why were mobile cranes used instead of tower cranes for key lifts?

Mobile cranes offered flexibility, rapid repositioning, and the ability to work in extremely confined areas around the cathedral.

Which cranes performed the highest lifts?

Two Liebherr LTM 1350-6.1 all-terrain cranes handled the highest and longest-radius lifts, including installation of the spire.

What made this project especially challenging?

Limited space, historic preservation requirements, simultaneous trades, and strict safety protocols in a dense urban environment.

Were the cranes involved throughout the entire reconstruction?

Yes. Liebherr cranes were present from early stabilization through final completion and reopening in late 2024.

What role did crane operators play?

Operators worked in rotating shifts, coordinating with ground crews and restoration teams to execute precision lifts at extreme heights.
