Liebherr careers
We dig it!
Liebherr components for tunnelling are specifically designed for toughest loads in continuous operation and have a proven track record of success in the field. You will find them in tunnel boring machines from renowned companies in numerous tunnel boring projects all around the world.
No time for downtime
Tunnel boring equipment is facing several challenges during operation. On the one hand there are extreme soil conditions, from hard rock to erosive soil and EPB. On the other, long project scopes and narrow timeframes with short reaction times. Given these circumstances, one thing is clear: You have no time for machine-downtimes.
In order to assure a successful project completion it is therefore essential to have, above all, reliable equipment.
Premium components for your tunnel boring productivity
You can rely on Liebherr components at all times. They are designed for toughest loads in continuous operation and are thoroughly tested on the company‘s own test benches. Whether it‘s a railway tunnel in Siberia or a new metro line in Mumbai - Liebherr components have successfully been put to use in the field. Renowned global companies are using Liebherr’s portfolio for numerous tunnel boring projects all around the world.
“Liebherr is more than a supplier, they are a partner that we can depend on to supply the most critical components on our machine.”
