A major milestone in the restoration of the historic Basilica of Saint-Michel has been achieved as a new Liebherr LTM 1250-5.1 mobile crane successfully dismantled heavy scaffolding around the iconic church tower in Bordeaux, France.
The project required high-precision crane operations at heights of up to 81 metres, highlighting the capabilities of one of the world’s most powerful five-axle mobile cranes.
Precision Engineering at a World Heritage Landmark
The free-standing tower of the Basilica of Saint-Michel—rising 114 metres high—had undergone an extensive five-year restoration of its delicate spire and ornate architectural details.
Once the restoration was completed, the complex steel scaffolding structure surrounding the tower had to be dismantled safely without damaging the newly restored stonework and decorative finials.
To complete this demanding task, French industrial services company Groupe Foselev deployed its brand-new Liebherr LTM 1250-5.1 mobile crane, marking the crane’s first operational assignment.
High-Precision Lifting at Extreme Heights
The crane was configured with:
- a 60-metre telescopic boom
- a luffing jib
- a 22-metre hydraulically adjustable double folding jib
This setup enabled the crane to reach a hook height of approximately 81 metres while manoeuvring around the intricate scaffolding.
The dismantling process involved lifting steel components weighing more than four tonnes at heights approaching 68 metres, while also navigating around structural obstacles created by the scaffolding framework.
The crane’s adjustable lattice tip allowed operators to reach deep inside the 25-metre-wide scaffolding structure, which completely surrounded the stone tower. From just two crane positions, the entire structure could be dismantled piece by piece.
Skilled Crane Operation Ensures Safe Dismantling
The delicate work demanded exceptional precision from the crane operator.
David, the operator handling the crane, carefully guided the hook through tight spaces while workers detached scaffolding elements at height. Loads were manoeuvred past freshly restored turrets and finials without risk to the historic structure.
Scaffolding specialist Thibaut praised the crane’s accuracy, describing its load control as “très, très précis” (very, very precise).
Interestingly, it was David’s first experience operating a Liebherr crane, after previously working with other manufacturers.
“Switching to Liebherr is a bit like switching from a Renault to a Mercedes,” he joked, highlighting the machine’s performance and handling.
Foselev Highlights Performance of Liebherr Crane
Following the successful operation, Joël Karotsch, head of the Bordeaux branch of Groupe Foselev, described the equipment as perfectly suited to the job.
“The hydraulic jib is particularly convenient and indispensable for this application,” he said after visiting the site.
The Foselev Group operates more than 500 cranes worldwide, including 30 units stationed in Bordeaux. According to Karotsch, around one-third of the fleet consists of Liebherr cranes, a number expected to increase due to the machines’ advanced technology, durability and strong customer support.
A Successful Maiden Operation
The successful dismantling of the scaffolding marks the first operational deployment of the Liebherr LTM 1250-5.1 for Foselev and demonstrates how modern crane technology can support complex restoration work at historic landmarks.
The operation also highlights how precision engineering and skilled operators play a crucial role in preserving architectural heritage, ensuring monuments like the Basilica of Saint-Michel continue to shine in their restored glory.
