How is Mammoet UK thriving?
The result was the SK6000.
For industry
Mammoet offers heavy lifting and transport services to energy and infrastructure customers in the UK, blending local knowledge with the expertise of a global organization to deliver more efficient supply chains.
The solution – Using 4,200t of ballast as its anchor, the SK6000 can lift up to 6,000 tonnes, while in its base configuration, a maximum radius of 160m is achieved. This gives it a minimum reach longer than two football fields, and the capacity to lift the weight of over thirty 747 aircrafts.
For government
The crane is rated for a load moment of 520,000 tonne metres: a common measurement for strength in the industry. This is well over one and a half times greater than the rated load moment of its predecessor the SK350 – which has a maximum capacity of 5,000t and 350,000 tonne meters, and was previously the world’s strongest land-based crane. This load moment is also more than double its nearest competitor.

Whether installing the New Wear Bridge in Sunderland, marshalling key components for Hornsea Offshore Wind Farm or helping to install power generating nuclear components at Hinkley Point C, Mammoet is helping communities and economies to thrive, across the country. Moreover, it is innovating to solve the central challenges of the energy transition, bringing down the carbon impact of its own operations through the development of electric equipment, and elsewhere exploring alternatives such as HVO and hydrogen to lower emissions. This extends to its very largest equipment. Mammoet’s SK6000 crane – delivered to the market late last year - is not only the strongest land-based crane in the world – but has been built with full electric operation in mind – from the grid, hydrogen or battery packs. The challenge – As populations grow, so do our energy needs. Chasing larger yields at higher elevations, offshore wind components are growing taller and heavier by the year. New nuclear plants are utilizing larger components to build facilities from fewer pieces and hence bring them online quicker - providing a reliable base load. In the petrochemical sector, facilities must modernize and diversify their product ranges - often without expanding their footprints. To serve these needs and more, a new crane was needed with an enhanced lifting capacity, capable of hoisting loads at a greater height and further outreach than ever before. In so doing, this machine would safeguard the future constructability of offshore wind facilities, while allowing customers across the energy and civil sectors to redesign supply chains and realise greater efficiencies than ever before possible.
Aside from mere technical specifications, this crane marks a step away from traditional product-based thinking, with Mammoet seeing the necessity for scalable and versatile lifting systems due to the pace of growth in the market. With wind turbines, construction modules, and reactors growing in size at an increased rate, systems such as the SK range of cranes allow its customers to realise economies of scale comparatively quickly. By designing the SK series in a modular fashion, it can grow incrementally alongside market demands and becomes more resilient against obsolescence than bespoke solutions. Sustainability is also central to its design. Indeed, using existing components from the SK series helped to save around 4,000 tonnes of CO2 during construction. Further, being fully electric, it offsets 400 tonnes of carbon annually during its operational life. As proof of concept, all operating modes of the SK6000 have been tested using electricity, powered by containerised batteries with output equivalent to 20 electric cars. The SK6000’s versatility, precision, and sheer lifting power enables Mammoet customers to transition to cleaner power sources and build more safely and efficiently in larger pieces – shrinking the logistics, integration and
▸ What more can we do to enable the energy transition to move at pace to reach our goals from COP? ▸ Mobility of people, equipment and services is vital to tackle challenges on a global scale. This is becoming more difficult. ▸ How can we encourage young people to consider working in the construction industry? ▸ Promote the skilled trades to young people. Why wouldn’t someone want to be a crane operator? It’s a job that offers the chance to travel the world, working on exciting projects - and earn a good living whilst doing so.
