When logistics moves mountains: EMIL EGGER brings a 1,000-tonne crane to the construction site

Assembly of a Liebherr LR 11000: Transport, assembly and logistics explained

Before a large crawler crane even makes its first lift, an impressive logistical feat has already taken place. A crane such as the Liebherr LR 11000 is completely dismantled for transport and delivered to the construction site in numerous individual parts.

Up to 30–40 lorry lads are required to deliver all the components – including crawler tracks, the slewing platform, boom sections, counterweights and accessories.

Individual parts weigh up to around 60 tonnes.

The actual assembly then begins on site:

Assembly of the crawler tracks and slewing platform
Assembly of the counterweights and derrick system
Installation of the winches and drive units
Step-by-step erection of the main boom
Safety checks and fine-tuning

Depending on the configuration, the complete erection takes around 3 to 5 days – and requires a well-coordinated team and precise planning.

Only then is the crane ready for its actual task:

Moving heavy loads weighing several hundred tonnes with millimetre precision. Large cranes take centre stage on the construction site – yet even their assembly is a logistical heavyweight.
