World's Largest Crane Has Nuclear Build Future

Belgiam industrial Sarens has launched what it claims is the largest crane in the world, which will have a future – and a start – tied directly to the nuclear power industry in Europe, the company said.

Worlds Largest Crane -- SarensOne of the crane’s first assignments, if not the first, will require a four-year presence at the Hinkley Point C two-reactor build in Somerset, England, starting next year, the World Nuclear Association reported.

The company said the plant had a future that would be tied to nuclear power. “Hinkley Point C is only the first of many new nuclear power plants that will be built in the UK and abroad in the coming years, and we expect the SGC-250 to be vital to those projects,” the company said.

The crane’s official name is the SGC-250. It was launched Nov. 9 at the port of Ghent in Belgium with a celebration that included journalist and industry officials. Sarens Chief Executive Officer Wim Sarens and Director of Technical Solutions, Projects and Engineering Car Sarens both addressed those assembled for the event.

The SGC-250 is the first of the 3rd generation of ring-basee cranes the company has designed. It has a maximum load of 250,000 metric tons which allows for lifts of 5,000 metric tons. It has a large radius of 100 meters and with its heaviest lifts it will have ground pressure coming in under 25 metric tons per meter squared.

The capacities are made possible by a high number of wheel bogies on the double ring beams and the utility of spreader mats. The main boom is 118 meters and can be extended to 160 meters; the jib can reach up to 100 meters.

With the combined jib and boom capacities, the crane can reach a height of 250 meters with a radius of 275 meters. “This flexibility guarantees that Sarens is capable of building whatever is needed by the client, all on a double-ring design of no more than 48.5 meters, which constitutes the outer diameter.

In addition, the crane, which gets around on hydraulically retractable wheels, can operate two hook blocks, one on the main boom and the other on the jib. This allows the crane to cover each spot on the jobsite, “while still offering the combination of strong and fast,” the company said.
