Description

  •
    Die angeführten Kugeldrehverbindungen benötigten jeweils biegesteifen Unter- und Oberbau. Bei extrem hohen Kippmomenten und Vertikalkräften wird der Kugellaufbahadurchmesser der zweireihigen Kugeldrehverbindungen größer als 4000 mm, damit wird erheblicher Aufwand in der Stahlkonstruktion, zur Erfüllung der Förderung biegesteifer Unter-und Oberbau, erforderlich.
