摘要:
A load measuring device for measuring the pulling up load of a monocystalline rod (38) grown by the Czochralski method utilizes a strain gauge (20). The monocrystalline rod (38) is pulled up by wire rope (36) consisting of multiple strands. The pulley (34) guiding the wire rope between a drum (36) and a crystal holder (44) has a guide groove which has a cross-sectional shape which is substantially identical to a semicircle circumscribing the wire rope.
