‘World’s strongest’ land-based crane launched

The 6,000 tonne capacity super heavy lift ring crane, the SK6000, has been assembled at the company’s facility in Westdorpe, Netherlands.

Mammoet used its own cranes for the assembly, which began in June this year, including a 250 tonne capacity crawler crane and a 140 tonne Gottwald mobile harbour crane.

The SK6000 is capable of lifting 3,000t to a height of 220m and will allow the use of new construction techniques for offshore wind projects and onshore new build projects like nuclear plants.

The crane’s maximum lift capacity is 6,000t, utilising 4,200t of ballast to lift with a maximum ground bearing pressure of 30t/m².

The crane can be transported using shipping containers to any location in the world and offers full electric power capability from battery or supply from the grid.

The crane is currently undergoing testing at Westdorpe, ready for deployment on its first project later in the year.

Gavin Kerr, director global services at Mammoet, said, “This crane is truly a world record feat of engineering, with a production schedule to match.

“Hundreds of colleagues have been directly involved with its development across the business.”
