Third 1,000t crawler for MaxiKraft

MaxiKraft has taken delivery of its third 1,000 tonne Liebherr LR 11000 crawler crane.

The new crane was shipped directly to its first job at the Dünfus wind farm near Cochem south west of Koblenz, where the crane was employed to assemble Vestas 5.6MW wind turbines.

The heaviest component is the gondola which weighs around 100 tonnes. The crane had to lift it from the ground and travel with it for around 20 metres before raising it to a hub height of 169 metres. The lift took a total of around two hours.

MaxiKraft configured the LR 11000 with 162 metres of main boom, topped by a 21 metre fixed offset lattice jib and 42 metre derrick boom. The crane is equipped with six winches as standard for the two hook blocks, the luffing gear for the main boom and luffing jib as well as the V-frame for ballast positioning.

Once the last rotor blade is placed, the crane will be dismantled and loaded onto 50 trucks for the move to the next site. The widest component has an overall width of 3.5 metres and a height of 3.2 metres.

MaxiKraft chief executive Maik Kanitzky said: "With its special configurations, the LR 11000 offers enormous lifting capacities for wind power assemblies. But it also offers flexible deployment options for other applications."

Steffen Lehmann who manages the large crane operation at MaxiKraft added: "For us, the highly flexible set-up versions and boom combinations of the Liebherr lattice boom cranes are the decisive factor. Having permanent control of all parameters of a lift is important. Our drivers rate the Liccon2 control system positively. On three large screens, it provides real time information about load, winch pull, boom position, ground pressure, centre of gravity, and many other parameters - plus the extreme sensitivity of the equipment when driving, luffing, and turning."

MaxiKraft runs a fleet of telescopic, lattice and crawler cranes ranging from 25 to 1,000 tonnes, with trailers of up to 300 tonnes payload. The group includes five companies serving Saxony, Saxony-Anhalt, Thuringia, Brandenburg, Berlin, Lower Saxony and Bavaria with a total of 23 branches
