Prangl GmbH Lifting on Esztergom Cathedral Restoration with LTM 1250-6.1 from Liebherr

To prevent damage to the windows and walls, it was necessary to remove the entire roof structure of the dome.

A Liebherr LTM 1250-6.1 mobile crane from the Austrian crane company Prangl GmbH was used during the restoration of Saint Adalbert’s Cathedral in Esztergom, Hungary.

In the course of the current restoration of the cathedral, the large bell, weighing almost 6t, had to be lifted out of its tower so that the appropriate work could be carried out on it. To prevent damage to the windows and walls, it was necessary to remove the entire roof structure of the dome. An LTM 1250-6.1 from Prangl was given this task.

“The time pressure was particularly challenging on this job. For the complete operation – all tower and bell parts had to be lifted out – the time window was limited to less than two days. The original plan was to use a smaller crane with an auxiliary boom. However, due to the time pressure, this was not possible. That’s why we chose our LTM 1250-6.1 for the job. The work was no problem for the 250t crane with its 72m main boom,” explains Gábor Kopasz from the Budapest branch of Prangl-Hungaria Kft. At a height of around 70m, the LTM 1250-6.1 lifted the roof structure with its five extended telescopic sections and lowered it to the ground. This made it possible to lift the large bell out of the tower.

Due to the limited space, the operation had to take place above a basement construction. In order to guarantee safe working conditions, the supports were underlaid with special steel base plates.

The reconstruction of the cathedral is planned for spring 2023, for which Prangl has also been commissioned to perform the lifting work.

Coincidentally, Esztergom is twinned with Ehingen, the headquarters of Liebherr mobile and crawler crane production where the LTM 1250-6.1 was built.
