Belgium-based crane rental comany Sarens has launched the SGC-250 crane, which according to the company, is the largest in the world in both size and capacity. This crane has a maximum load moment of 250,000 metric tonnes, allowing it to lift 5,000 tonnes. At a larger radius of 100 metres, it can lift 2,000 tonnes and the ground pressure remains below 25T/m².
The main boom, which is now 118m, can be extended up to 160m and the jib can be extended up to 100m. This combination can reach a height of about 250m or a radius of 275m. This flexibility ensures that Sarens is capable of building whatever is needed by the client, all on a double ring design of no more than 48.5m, which constitutes the outer diameter.
In addition, the crane can operate two hook blocks: one on the main boom and one on the jib. In this way, the crane can cover each spot on the jobsite while still offering the combination of strong capacities and fast operations.
Besides power and flexibility, Sarens has put significant effort on safety and continuity. This can, for example, be seen on the highest performance level (PL E) and full redundancy system on the hoisting and slewing system which is achieved by intelligently connecting and steering all 12 engines in six power packs.
The SGC-250 can relocated and fully rigged on site, from one lifting position to another. The crane has two sets of wheels: one for slewing 360° and one for travelling. The second set is hydraulically retractable and is pushed out whenever the crane needs to travel.
The SGC-250 will shortly move to its first project in the UK, supporting the construction of the Hinkley Point C nuclear power station – currently the UK’s largest and most complex civil engineering project. The SGC-250 will help the Hinkley Point C team lift and shif the station’s heaviest pre-fabricated components. The machine is planned to lift more than 600 pieces of pre-fabrication, including the five major parts of each unit’s steel containment liner and dome.
