a considerable number of feed-through channels could be created in the beams. The crane was transported over inland waterways to Rotterdam and after a reconstruction period of 10 weeks,
was returned to the industrial building.
The drive and control units were configured redundantly, completely following the Tata Steel philosophy. Because PHK23 is a critical link in the operational processes of the oxygen steel plant,
