摘要： A crystal growing system can include a spool-balanced seed lift assembly for rotating and lifting a seed crystal supported by a cable. The seed crystal is supported along and rotated about a lift axis. The spool-balanced seed lift assembly includes a spool that rotates on, and has a center of gravity along, an axis that intersects the lift axis. As the spool rotates, it moves axially along its axis to avoid displacing the cable from the lift axis. A guide pulley positioned below the spool is used to direct the cable between the lift axis and a spool-tangent axis to minimize displacement of the cable as it is raised and rotated.
