This year, Sarens will debut its new SGC 250 crane, the largest in its fleet. And the crane's first project is a high profile one.

The SGC 250 will be deployed for the four-year, £20 million (AU$34.6 million) Hinkley Point nuclear project in Somerset, England, on behalf of joint venture clients Bouygues Travaux Publics of France and Laing O'Rourke Construction of the UK. 

Six kilometres of rail have been laid on-site, allowing the crane to travel between three different lift locations without the need for disassembly or re-assembly. 

The SGC 250 will be mobilised overland from Gent to a nearby lay down yard before it is shuttled to the project site. An estimated 280 trucks will be required to deliver the entire SGC, though at the moment, the narrow lanes leading to the site only allow 10 trucks per day. Sarens said plans are in the works for a purpose-built access road at the site, but noted that a lot of planning will still need to go into the logistics of delivery. 

Once on site, the SGC 250 may need to perform lifts at night, using an anti-collision system. This would be done to minimise disruption during the day, when 52 tower cranes will be operating at the work site. The crew would need light to operate at night, but in this case the local bat population poses a special challenge. The team will need to find solutions that do not disturb the bats, which are a protected species. 

With everything in place, the SGC 250 will begin performing various lifts ranging from 50t to 1.150t or more, and with radiuses of up to 165m. It will pick up and install prefab concrete elements, steel structures, and reactor equipment directly from each prefabrication position. A second crane, the CC 2800, will assist as a rigging crane.
