At 4B, we offer an annual maintenance service, which is available for both electrical and mechanical components.


  • All the parts of the system / installation are checked to be in good working order.
  • Any defects are highlighted and an action list is sent our along with the full inspection report.
  • (The services are the same as in our "Commissioning Service"- just on an annual basis.)


  • Machines are visually inspected for the component and structural wear signs.
  • Full datasheet is created with all the key dimensions, list of spare parts, type of drive and gearbox, bearings, etc.
  • Recommendations can be made of how to improve performance, reduce spares stock and decrease power consumption.
  • Action list is created, which highlights most urgent changes and improvements.
