Abstract

In a device for handling heavy components of a crystal puller according to the Czochralski method, a supporting beam that can be pivoted about one vertical leg of a supporting frame and vertically adjusted includes holding claws for accommodating components or auxiliary devices. Profile rails, on which a carriage can be laterally displaced, are arranged perpendicular to the supporting beam. The carriage can be connected to a receptacle for gripping and holding the crystal.
