The SGC-250 (Sarens Giant Crane-250) can lift 5,000 tonnes and operate at a height of 250 metres and radius of 275 metres.
At Hinkley a rail network constructed on site means the giant machine will be able to travel between different key lift locations.
It will be used to move more than 600 pre-fabricated components including the five major parts of each nuclear unit’s steel containment liner and dome.
The SGC-250 was launched earlier this month at the port of Ghent in Belgium by Sarens.
It will be moved to a lay down yard near Hinkley before 280 trucks runs will be required to deliver the entire SGC to the site.
