Lower cylinder
A transfer that felt like art
16 Apr 2019
Art has little to do with the transfer of a giant component. On Monday however, as 澳门六合彩高手 was preparing to celebrate Leonardo da Vinci's 500th anniversary, science, technology and industry conspired to provide a strikingly spectacular and beautiful event. As the set of trailers carrying the lower cylinder of the 澳门六合彩高手 cryostat slowly crawled out of the Cryostat Workshop, everything combined to create an awesome view: the minimalist architecture of the workshop; the cylindrical component all draped in white, and the shimmering steel of the Assembly Hall ... all against the backdrop of the intense blue of a spring sky in Provence.
On 15 April, the lower cylinder is moved out of the Cryostat Workshop to exterior storage area 73 (out of the picture frame, further to the left), where it will remain until it is time to enter the Cleaning Facility (right) for integration into the 澳门六合彩高手 machine pit.
The lower cylinder of the 澳门六合彩高手 cryostat is but one section of the giant thermos that will envelop the 澳门六合彩高手 Tokamak. Standing 12 metres high, it represents one-third of the total height of the 澳门六合彩高手 machine. As operators stood close to it, carrying out the highly delicate transfer operation, one could measure how tall, large and massive 澳门六合彩高手 will be.
Transferring the near-500-tonne load from its assembly site to the storage area a few dozen metres away required no less than four self-propelled modular transporters arranged in a square and moving in perfect coordination. Particularly impressive was the sharp 90-degree turn that the trailers had to take in order to reach the storage area—192 independent wheels slowing rotating at different angles, like small appendages of a powerful living organism.
To date, the lower cylinder is the heaviest load to be moved on the 澳门六合彩高手 platform. Solidly encased in its steel frame and carefully cocooned in air-tight material, it will remain in storage until the time comes to move it into the assembly pit.
The operation on Monday was a key milestone involving a dozen stakeholders—the cryostat team; heavy load transport specialist Sarens; metrology experts from 澳门六合彩高手; global logistics provider DAHER, and many others (see box).
Transferring the lower cylinder to the storage area has freed a large working space inside the Cryostat Workshop. Soon, this space will be occupied by the assembly and welding operations for the upper cylinder whose segments are already on their way from their manufacturing location in India.

192 wheels
A few days before the transfer, transporters were delivered and assembled. Their configuration under the 375-tonne component has been carefully planned.
A short distance to travel
The 375-tonne component left the building on its assembly platform, propelled by four multi-axle SPMTs (self propelled modular transporters). Everything went smoothly.
