Abstract
A method, mechanisms and jig for handling a member of a crystal pulling apparatus are disclosed. The crystal pulling apparatus grows a single crystal from a melt of a crystalline material by a CZ method. Handling of a graphite crucible or the like of the crystal pulling apparatus, including a vertical moving operation, a swinging operation, or the like, is performed using a crane and a lifting jig. This makes it possible to readily move the member of the crystal pulling apparatus vertically and otherwise without relying on manual labor.
