Abstract
A grip for a crystal ingot mounted on a pull shaft has grip arms which cross each other. These grip arms have respective holding jaws on the side of the crystal ingot opposite the swivel bearing of the respective grip arm. Furthermore, a respective activating arm is provided on them on the side of the grip arm opposite the swivel bearing. As a result of this configuration, the grip is biased by the weight of a gripped crystal ingot in the closing direction.
