ITER (International Thermonuclear Experimental Reactor) is a research and engineering megaproject to build a nuclear fusion reactor. Located in Provence, southern France, ITER will be the world’s largest magnetic confinement plasma physics experiment.

Sky Climber was selected to provide the access solution for the vertical walls in the central cylindrical structure that will house the vacuum vessel of the plasma container. The most effective solution was determined to be five special cantilever platforms suspended from a monorail system. The platforms will be used during the construction phase to install all the various parts around the plasma container.

The position of the monorail was determined by the steel structure and was further away from the vertical walls than was ideal to position the platforms. The platforms were constructed with offset suspension points that allowed the platforms to reach in 1.6 meters from the line of the monorail. Counterweights were fitted to the rear of platform to keep the system in balance and provide a stable work area.
