There’s a natural human propensity to pursue development and enhancement, which is why our endeavours typically focus on larger, morepowerful, faster, muchbetter. And that’s noplace more apparent than in the world of cranes.
In reality, there is a well-documented competitors to see who can style and develop the “world’s greatest crane”. Depending on your picked requirements, the title-holder can differ: does it mean the theoretical heaviest load (seldom a useful truth) or is it the optimum load at the provided outreach? However you desire to specify it, the competitors are normally a choose coupleof – and these days either Belgian or Dutch.
Even this is overshadowed by ocean-going cranes run by another Dutch business, Heerema, whose SSCV Sleipnir is a semi-submersible vessel fitted with a set of 10,000-tonne capability cranes. When it comes to land-based cranes, nevertheless, it is Mammoet and its Belgian competing Sarens that complete over who has the greatest tool.
The newest maker to stake its claim is the SK6000 ring crane from Dutch heavy-lift expert Mammoet.
The brand-new SK6000 has a optimum capability of 6,000 tonnes and is capable of lifting parts weighing up to 3,000 tonnes to a height of 220m.
For the past coupleof years, Sarens hasactually laid claim to the ‘biggest-crane’ title with its SGC 250 – nicknamed Big Carl – which has a optimum lifting capability of 3,000 tonnes and a optimum load minute of 250,000 tonne-metres.

Big Carl was established specifically for the Hinkley Point C nuclear power station job in Somerset where it hasactually been working giventhat late2019
Before that, another huge ring-crane, Abnormal Load Engineering’s AL.SK190 declared to be the world’s biggest. This maker was utilized by Keltbray on the Earl’s Court demolition job in London in2017 ALE, a British business, is now part of Mammoet.
“Mammoet gotten ALE in 2020, and along with it the intellectual residentialorcommercialproperty of the SK series and other heavy lifting innovations,” states Mammoet. “Since then, the engineering competence present in the service – the world’s biggest heavy lifting and transportation engineering center different to everyday operations – hasactually made the production of this record-breaking maker possible.”
The SK6000 was created totally in-house by Mammoet itself, which declares to have “the world’s biggest concentration of heavy lift engineering competence”. This group invested anumberof years working on the crane from engineering ideas to last in-depth styles, after which production of the elements was contracted to a little handful of reliedon fabrication professionals.
In June this year, all the elements for Mammoet’s brand-new SK6000 ring crane were provided to Mammoet’s Westdorpe backyard in Zeeland where a group of 20 employees is now hectic putting it all together allset for load-testing – a procedure anticipated to last at least 6 months.
Initial works consistof assembly of the crane’s base frame, power loads and control space. Some of the parts are substantial (the primary boom areas step 4m x 8m in cross-section) and Mammoet is utilizing anumberof of its ‘smaller’ cranes, consistingof 2 250-tonne capability spider cranes and a 140-tonne Gottwald harbour crane, to lift and position them.
Ring cranes in this class are planned for transportation by sea to task websites anywhere in the world. For this factor, they are inevitably created to be damaged down into parts little sufficient to fit into requirement steel shipping containers. In the case of Mammoet’s SK6
