Abstract
A crystal support for a crystal pulling system includes two catches that have a respective retaining jaw that is placeable against a thickened neck portion of a crystal. The two catches are moveable into a bearing position in which the two catches bear on the thickened neck portion and into a releasing position in which the two catches are away from the thickened neck portion. In the bearing position, respective contact points of each retaining jaw at which the retaining jaws bear on the thickened neck portion are located on respective sides of a parting plane. The parting plane extends at an angle to at least one of the pivot axes of the catches and, in the bearing position, the respective contact points of each retaining jaw are located on both sides of a crystal plane that extends through an axis of the crystal and parallel to the pivot axes.
