Momentous in both size and strength, the Liebherr MTC 78000 can safely lift up to 2,000 tonnes and is one of the world’s biggest slewing cranes.
The Liebherr MTC 78000, which is a mast-type crane, is mounted onto the offshore supply ship OSA Goliath, which is currently owned by Oceanografia.
Cranes such as Liebherr’s, which is celebrating its 50th birthday this year, are vital to the offshore energy industry. They are used to install offshore wind power stations and for the assembly and disassembly of oil and gas rigs, as well as for pipe laying. Without heavy lifting cranes such the Liebherr, offshore construction on this scale would be impossible.

When the Liebherr MTC 78000 was mounted onto the OSA Goliath in 2009, it took a specially trained team of 50 mechanics 23 days to assemble the crane. Three years later it’s still going strong.
The heaviest component of the Liebherr MTC 78000 is its slewing platform which weighs an eye watering 370 tonnes. This is followed by the machinery compartment and drive components weighing 240 tonnes and the lower mast section and the upper mast section which weighs 250 and 160 respectively.
Designed by using the conventional, highly reliable metallic bearing technology, it can lift up to a 35 metre radius through 360 degrees. It also boasts a maximum dynamic torque of 78,000 metres / tonnes, an 87 metre boom and a 70 tonne swing ring with a diameter of approximately nine metres.
Steady business for Liebherr
In its annual report released this week, German Liebherr reported that, overall, business was good.
It stated that, in all, incoming orders remained at satisfactory levels, but that there was still uncertainty in a large number of markets, with customers frequently postponing projects leading to orders being cancelled. However, despite this, machines that did become available in this way Liebherr managed to sell elsewhere, without a delay in most cases.
Last year Liebherr introduced a new series of heavy lift offshore cranes to the market, along with other manufacturers such as Huisman, who in June introduced a new series of large offshore cranes, signalling an increasing demand for these specialist cranes.
Most notably, Liebherr developed the heavy lift offshore crane type CAL 64000 – 1500 Litronic which is used for the installation of offshore wind turbine generators.
In conclusion to its report Liebherr remained positive saying that, overall, there was an increase in orders received in 2012 and the company expects turnover from its tower crane area, in particular, to be higher in 2013.
