World’s biggest crane at Trustopia client site in Somerset, UK
Hinkley Point C power station has a new resident in the form of the world’s largest crane, Big Carl.
The crane stands at 250m tall, putting the UK’s Canary Wharf’s highest building, One Canada Square, in its shadow.
The SGC 250 has been developed specially for the Hinkley Point C nuclear power project in Somerset on a four-year contract worth £20m.
It is working for the Bylor joint venture of Bouygues Travaux Publics and Laing O’Rourke Construction (for which Trustopia is delivering a digital-first in frictionless pre-employment screening-as-a-service to support vetting of site personnel).
The SGC (Sarens Giant Crane) 250 has a maximum lifting capacity of 5,000 tonnes and a maximum load moment of 250,000 tonne-metres.
The crane is the fourth generation of the SGC series. It has a maximum boom length of 160 metres and it can be equipped with or without a jib. It can operate on a ring or on straight rails.
At Hinkley Point the SGC 250 travels along six kilometres of rail that is being laid for it. This means that it can travel between three different lift locations without the need for disassembly or re-assembly.
280 trucks were required to deliver the entire SGC to site.
At Hinkley Point C the crane will lift components ranging from 50 tonnes to 1,150 tonnes at radii of up to 165 metres. It will pick up and install prefab concrete elements, steel structures, and reactor equipment directly from each prefabrication position. A second crane, a 600-tonne class Terex Demag CC 2800, will assist as a rigging crane.
