Mammoet has started assembling what the company says is the world's strongest land-based crane, the SK6000, at its Westdorpe facility in the Netherlands. 

The SK6000 ring crane will offer full electric operation. This means it enables the transition to cleaner power sources while driving down the carbon impact of energy projects themselves, without sacrificing power.

The SK6000 has a maximum capacity of 6,000 tonnes and is capable of lifting components up to 3,000 tonnes to a height of 220 metres. Its sheer lifting power allows Mammoet users to build more efficiently in larger pieces, shrinking the logistics, integration and mobilization phases of projects.

The crane provides a leap forward for projects in emerging energy sectors, supporting the continued constructability of wind turbines and foundation components needed to achieve higher yields from offshore wind farms. It also unlocks new modular construction options for nuclear facilities, with increased cost-effectiveness and safety.

In the oil and gas sector, the SK6000 helps new build and expansion projects. It builds on the design philosophy of Mammoet's SK190 and SK350 series, which are proven in the market. 

Following the mobilization of all parts to Mammoet's Westdorpe site, initial works include the assembly of the crane's base frame, power packs, and control room. Mammoet's auxiliary cranes are supporting the build, including two 250-tonne crawler cranes and a 140-tonne Gottwald mobile harbour crane.

"This is a thrilling new chapter for Mammoet and modular construction in heavy industry, as we see the SK6000 taking shape," said Koen Brouwers, project manager for the SK6000. "It will offer a hook height, outreach, and lifting capacity far in excess of any crane on the market. We are excited to bring this groundbreaking technology to our customers, helping them achieve their project goals with greater efficiency and more sustainably."

Assembly of the SK6000 is scheduled to be completed during the fourth quarter of 2024.
