Dämpfung von Konstruktionsschwingungen an Hafenportalkranen - eine elegante und preiswerte Lösung zur Beruhigung von Kranschwingungen

(PresseBox) (Magdeburg, )
Der schwingende Kran

Schwingungen an Krankonstruktionen sind ein natürliches Phänomen. Durch Wind, Fahrbewegungen der Katze oder leichte Kollisionen beim Umschlag entstehen Kräfte, die den Kran anregen. Oft sind diese periodischen Bewegungen klein. Mit zunehmender Krangröße und leichterer Bauweise kann es vorkommen, dass diese Schwingungen deutlich spürbar und sichtbar werden. Sie verunsichern die Kranfahrer und belasten die Krankonstruktion.

Um dieses Problem zu lösen, wurden schon einige Wege beschritten. Eine Möglichkeit bestand darin, mit Hilfe von passiven großen Massen (bis zu 60 t) die Dämpfung von Containerbrücken zu vergrößern.
