TECHNOLOGY

KÜHNEZUG relies on advanced, reliable technology Made in Germany. Get an overview of the different technologies we use in every one of our high-quality crane systems



Frequency Inverter Technology


Advantages of frequency inverter technology:

  • >> More user-friendly handling
  • >> More precise, smoother positioning
  • >> Less wear on gears, wheels and traverse rails


In combination with the frequency inverter technology, a number of innovations in drive technology can optionally be implemented:

Anti-sway control: The effective anti-sway control system reliably reduces uncontrolled swinging movements in the lifted load resulting from acceleration and braking forces. The system works actively with the control electronics of the drive unit motors, compensating for swaying motions of the suspended load within the system boundaries. The damping of swaying motions resulting from external influences such as inclined lifting or wind is not possible.

Anti-crab control: Reduces skewing of the crane. Poor crane runways, uneven wheel wear or unbalanced crane loading (e.g. when the trolley is at one end of the crane girder) can result in skewing of the crane. That means that the crane is slanted away from the crane runway rails during travel. This results in increased wear and more force exerted on the crane runway. The system works actively with the controller electronics of the drive units to reduce skewing of the crane during travel.
