HEAVY LIFTING Ӏ SECTOR REPORT
j “There is a temptation to think that heavy lifting is boys with big toys. But that is not the attraction for me; it is more about what we are able to make possible with them for society. For the Seagreen project, an offshore wind farm due to be located 30km off the east coast of Scotland, we are loading out jackets for what will be the deepest offshore wind farm in the world. We are working on the Hywind Tampen project in Norway which will be the largest floating wind farm ever in the world. Our cranes are unlocking bottlenecks, which helps
designers capture the economies of scale so valued in renewable energy projects, for example, by allowing simultaneous load-in and load-out of jackets; regardless of tide conditions. "If it's installing bridges,
you know you are connecting communities; if it is chemical complexes then we’re helping computing and healthcare industries to move forward. "We are sometimes a little bit
over-obsessed within our industry with having the biggest crane and the strongest crane. And, of course, that is cool, and I take great pride
in Mammoet’s large cranes; but we should really go back a little bit to the basics of why we are developing these products and why we want to be capable of doing these absolutely spectacular engineering projects. It serves a higher purpose actually. And for me that's where I find my calling. "The lifts are nice but, more
important, it is helping our clients ultimately to realise their ambitions to have a big impact on the way our children, and our childrens’ children, live. This is where I get the most pleasure. ”
The world's highest and largest sea-based box suspension bRidge
China’s Lingdingyang Bridge will be the world’s highest and largest sea-based steel box girder suspension bridge. Two record-breaking 270 m (886 ft) towers support the cables of this gigantic structure. Two Potain MD 3600 cranes played a key role in their installation. With a height of 282 m and a lifting moment of 3,600t the MD 3600 is the largest tower crane available from Potain and a perfect fit for the demands of large- scale bridge construction. To build the towers, the steel reinforcement for the concrete pillars was prepared off-site and then transported to the project to be placed in the pylon by the MD 3600 cranes. Because of the weight of the steel and the height at which it needed to be lifted, the Potain MD 3600 was the best option for this modular construction method that significantly reduced construction time. On July 19, 2021, both the east and west tower were topped off, allowing construction of the rest of the bridge to move to the next stage.
