Europäische Patentamt

On May 25, 2016, Mr Wolfgang Wichner was granted the European patent 2on his rotational sway control system.

With this system it is possible to rotate crane loads quickly around the vertical axis. The long-lasting oscillation normally occurring after the end of the turning process is completely avoided.

To achieve this, the CATS rotational sway control system acts on the rotation gear of the load attachment device.
