Delmeco replaced the crane control system and frequency drives for anode handling at Century Aluminium. The project involved upgrading an outdated Allen-Bradley PLC, HMI and frequency drives, which were replaced with a Siemens S7 PLC, HMI and Sinamics drives.

This crane is part of a 24/7 baking furnace process. To avoid disruption of this process, commissioning and testing activities were carried out during scheduled shutdowns.

For the automation and electrical engineering disciplines, the scope of work included, among others, the following activities:

  • Reading out the existing software and converting it to Siemens TIA Portal

  • Programming and testing the new Siemens PLC

  • Replacing the PLC and frequency drives

  • Testing

  • Commissioning of the new control system

Delmeco’s responsibility within this project was the modification, implementation, testing and successful delivery of the new crane control system.
