CPC: Lifting devices or pulling devices adapted for co-operation with fuel elements or with control elements (manipulators B25J)

Full Title

Full titles differ between systems:

IPC:

Arrangements for treating, for handling, or for facilitating the handling of, fuel or other materials which are used within the reactor, e.g. within its pressure vessel > Details of handling arrangements > Lifting devices or pulling devices adapted for co-operation with fuel elements or with control elements

CPC:

Arrangements for treating, for handling, or for facilitating the handling of, fuel or other materials which are used within the reactor, e.g. within its pressure vessel > Details of handling arrangements > Lifting devices or pulling devices adapted for co-operation with fuel elements or with control elements (manipulators B25J)

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 1990.
