The two charging cranes will be manufactured at the Danieli workshop in Thailand, where they will be fully assembled and functionally tested in all their movements with trolley operating on the bridge.
Both cranes will be equipped will a regenerative system that recovers the braking energy of all the movements.
The first crane will be fully commissioned by July 2020 in line with the plant erection schedule, and the second crane will be started up by the end October 2020, as per contract.
