The M1-90-S is the largest movable scaffolding system in the world designed by BERD for the construction of four of the thirteen viaducts belonging to the High-Speed Railway Line that will link Ankara to Sivas.
Two equipments are being used in the construction of the four viaducts with a total of 6,151 m, in order to reduce construction time: the M1-90-S for spans up to 90 m, and the M55-S for spans up to 55 m.
The M1-90-S is entirely autonomous, lifting the supports using its own overhead cranes. Equipped with OPS system, which enables lighter equipment, the M1-90-S is constructing 90-metre spans. This equipment allows extending the maximum span of 78 meters of its predecessors to 90 meters.
The M1-90-S successfully completed its first viaduct (V15) last month. It is currently being dismantled in order to be reassembled in the first quarter of next year on the next viaduct.
