Our magnet unit is integrated in the crane control and is only adjusted via parameters. The tried-and-tested structure using standard power converters combined with a safety PLC for controlling the power converter and monitoring the switching states is retained. The structure of our crane control corresponds to category 2 or performance level C as standard. For ship unloading, the design of the control to category 3 or performance level D is provided by adding additional components.
Our technical innovations include the rapid excitation of the magnets when switching on as well as the temperature compensation of the partial load stages and the automatic battery check.
