World’s largest reachstacker

21 January 2019

The world’s largest reachstacker, developed in close cooperation between N.C. Nielsen and Blue Water Shipping, is being used to help with the heavy lifting of windmill towers, nacelles and other heavy haulage at the harbour area in Esbjerg, Denmark.

The gigantic reachstacker lifts a staggering 152t on the hook and was recently delivered by N.C Nielsen to Blue Water Shipping, and has now been put to work. N.C Nielsen said that the converted Konecranes 4545 reachstacker is an alternative to cranes for lifting these components.

“Now we can handle the heaviest lifting and transport tasks ourselves by combining our machines for the different projects. For instance, we can lift objects of up to 250t with the world’s largest reachstacker on one end and one of our 100t reachstackers on the other—or operate with extremely heavy objects hanging on the hook. This sets us up to handle the transport projects of the future,” said Søren Messmann, general manager of the port services division at Blue Water Shipping.

The reachstacker is the result of targeted development work between the two companies. Strict requirements regarding the machine’s performance had to be satisfied, and the technical specifications were defined in cooperation with Blue Water Shipping’s customers in the windmill industry. The ever larger and heavier windmill parts, the bearing capacity of the soil at the storage site, new types of lifting equipment and the desire for the hook to reach all the way to the ground were among the technical challenges.

“N.C. Nielsen has in the past developed incredibly robust reachstackers for the windmill industry, with a lifting capacity of 110 tonnes. Back then, many shook their heads at the project and its big ideas. But N.C. Nielsen proved that it could breathe life into the ideas. The development of the world’s biggest reachstacker is another step towards moving the boundaries of the heavy duty area,” the company said.
