  The first type is used for large diameter cores (>127mm), with specifications of 800X650X150mm. The number of rows depends on the diameter of the core:

  The second type is used for medium diameter cores (75~110mm), with specifications of 900X650X100mm and 6~8 rows:

  The third type is used for small diameter cores (<75mm), with specifications of 1000X650X60mm and 10~15 rows.
