New Liebherr LR 11000 Crawler Crane Working for MaxiKraft in Duisburg

Immediately after completing its first job erecting a wind turbine in southern Brandenburg, the new Liebherr LR 11000 crawler crane owned by crane and heavy haulage contractor MaxiKraft had the opportunity to show its capabilities at a steel casting plant. The 1000t crawler crane was transported around 600km to ThyssenKrupp in Duisburg by more than 30 heavy haulage vehicles to install a 200t crane girder, which had been completely repurposed at the steel casting plant. These crane girders, measuring 40m in length, are designed to transport hot liquid steel inside the plant.

In constricted space conditions, the LR 11000 had to be set up with 50t of central ballast, 170t of slewing platform ballast and 320t of derrick ballast within four days in its SL11DBV configuration with a 102m main boom and a 42m derrick boom. The hoist was completed on a Saturday so that the crane could then be dismantled again from the Monday and the steel plant could quickly restart operations.

Crane operator Marcel Kallwass is full of praise for both the crane and his team: “The delivery of the crane components was a logistical master class. Things were very tight, particularly when setting up the crane. But everything went very well. The LR 11000 is a fantastic crane. I’ve operated them all, from the LR 1600/2 to the LR 11350 and also large machines from other manufacturers.”

An SPMT module vehicle manoeuvred the colossal steel component from the preparation area to the crane where the LR 11000 picked it up on four giant shackles and then delicately placed the 200t at its assembly position at a lofty height. The 1000t crane even had to move a few metres with the massive load on its hook. Thick excavator mats had been put in position specially to distribute the load.

The old crane girder has been modified for its new purpose as a weather guard. Over the next few months, a mobile safety wall will be attached to it to provide the open building which houses the extrusion casting system with better protection from wind and rain.
