MAXIKraft – a conglomerate of five companies across Germany – have added a third Liebherr LR 11000 crawler crane to its burgeoning fleet.
With a maximum lifting capacity of 1000 tonnes and a maximum hoist height of 220 metres, Liebherr say the machine is equally adaptive and effective in environments such as port work, infrastructure, industrial construction, and wind power – something those in charge at MAXIKraft concur with.
“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,” said company owner Maik Kanitzky.
Additionally, the LR 11000 is powered by a Liebherr 8-cylinder 500 kW engine, and possesses a 162-metre main boom, 21-metre lattice type fixed jib and 42-metre derrick boom. The crane is equipped with six winches, responsible for two hook blocks, the luffing gear for the main boom and luffing jib as well as the V-frame for ballast positioning.
With a fleet already featuring two LR 11000 machines, the third of its kind will join other large lattice boom cranes, such as the LG 1750, the LR 1700-1.0, and the LR 1800-1.0, with large crane operations manager at MAXIKraft Steffen Lehmann highlighting the “highly flexible set-up versions and boom combinations” of Liebherr’s lattice-boom cranes as the “decisive factor”.
“Having permanent control of all parameters of a lift is important; our drivers rate the LICCON2 control system positively,” he said.
“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.”
Deployed almost immediately after being delivered to the German company, MAXIKraft put the crane to work assembling a 5.6-megawatt wind turbine for its first task, lifting components weighing up to 100 tonnes at a height of 170 metres – all well within the LR 11000’s capacities.
