Restricted installation space, high temperatures and a very dirty environment
For reasons of limited vertical space, the entire control system was not accommodated in an external switch room but in the gantry itself. For the same reason, the trolley does not travel above the two gantry girders but between them. And all the components used are designed for heavy-duty operation. Dipl.-Ing. (BA) Mike Götzensberger, project manager at Bang: "The crane is constantly exposed to large amounts of dust and high temperatures. The slabs and the hot holding furnace emit so much heat that temperatures up to 70 degrees Celsius are reached even just below the ceiling of the hall. "The motors are therefore fitted with fans, while heat protection plates have been installed at specific points and all electrical components are designed for high ambient temperatures. As requested by Bang, the hoist motor was developed specifically for this type of use so that it performs efficiently and effectively in adverse conditions.
