30-Second Takeaway
A Liebherr LTM 1650-8.1 mobile crane played a critical role in restoring operations at the Müden lock on Germany’s Moselle River after a December 2024 gate failure stranded 74 inland vessels. Working under a long-standing emergency framework agreement, crane specialist Steil Kranarbeiten used the 700-tonne crane to recover the damaged gate and install two 45-tonne replacement gate leaves, allowing the lock to reopen by early February 2025 and minimizing disruption to one of Europe’s most important inland waterways.
Emergency Response on a Critical European Waterway
The Moselle River, stretching 544 kilometers and forming the second-largest tributary of the Rhine, is a backbone of European inland shipping. A system of 28 locks and barrages ensures smooth navigation for freight vessels moving between Germany, France, and Luxembourg.
That system was put to the test on December 8, 2024, when a drive failure on an inland vessel caused severe damage to the Müden lock, forcing its closure just days before Christmas and stranding 74 vessels.
To respond quickly, the Mosel-Saar-Lahn Waterways and Shipping Authority (WSA) activated its long-standing emergency framework agreement with Steil Kranarbeiten GmbH & Co. KG of Trier. Supported by modern Liebherr crane technology, the team moved immediately to secure the lock and restore traffic.
Rapid Recovery Using Liebherr Mobile Cranes
Steil first deployed a Liebherr LTM 1200-5.1, while a Liebherr LTM 1650-8.1 was used to recover the damaged lock gate. Using a temporary dam beam system steel elements commonly installed during lock maintenance the team created an emergency lockage.
Working around the clock, Steil’s operators ensured that stranded crews were able to continue their journeys and reach home in time for Christmas.
According to Ulrich Zwinge of WSA Mosel-Saar-Lahn, once the immediate emergency was resolved, attention shifted to a permanent repair. Replacement gates, stored in Trier and customized with application-specific hydraulic and electrical components, were refurbished immediately. In just seven weeks, two fully prepared gate leaves were ready for installation at Müden.
Installing the 45-Tonne Gate Leaves
On January 24, 2025, Steil returned with its heavy-lift solution: the eight-axle Liebherr LTM 1650-8.1, fresh from wind farm work nearby.
Each 45-tonne gate leaf was transported to the lock site by water using a WSV push unit, then transferred onto a five-axle platform trailer with a 220-tonne crane. The trailer reversed approximately 200 meters to the installation area, where the LTM 1650-8.1 took over.
The crane rotated the gate from horizontal to vertical, stabilized it, and lifted it into position. With a working radius of 18.5 meters, the lift posed no difficulty for the crane, which was configured with:
52-meter main boom
75 tonnes of ballast
4-tonne hook block, reeved five times
Once lifted, the gate remained stabilized until the neck bearings were installed.
Designed for Confined and Complex Sites
Crane operator Torsten Schneider praised the LTM 1650-8.1’s handling and control, highlighting the LICCON control system and the crane’s ability to work efficiently in restricted spaces.
Steil’s decision to invest in two LTM 1650-8.1 cranes was driven by several features:
VarioBase®, allowing variable outrigger positioning for safe lifting in tight spaces
VarioBallast®, enabling flexible ballast radius adjustment depending on site constraints
At the Müden lock, sufficient space allowed use of the crane’s maximum outrigger base of 10,531 × 9,578 mm. However, positioning the full 96 tonnes of counterweight over the front of the crane extended setup time to approximately 3.5 hours still well within operational expectations.
“Under normal conditions, the crane is ready to lift in around 1.5 hours,” noted Torsten Schröder from Steil.
Lock Reopens Ahead of Schedule
Both gate installations and all related lifting operations were completed by midday, allowing the Steil team to stand down before the weekend. Final programming and commissioning work took approximately one additional week.
The Müden lock returned to full operation by early February 2025, restoring traffic on the Moselle and drawing national media attention for the precision and speed of the operation.
