4) Handling by the self-locking hooks under pri-
mary screws
In case of indoor current transformers, which are
equipped with primary terminal screws M12, it is
possible to hang the transformer on self-locking
hooks holding under the primary screws. The han-
dling can be done by hanging of the hooks on the
crane.
Note.
This system is recommended for types:
TPU, TPE, IHBF, KOFA. This handling system is vi
-
sualized on the picture.
Safety warning!
Lifting capacity of the hooks
and the crane has to be 200 kg at least. Always
make sure that the hooks hold safely on the
crane and on the transformer.
SAFETY WARNING:
During the manipulation with
transformer it is necessary to follow safety work
instructions. Never stand under the freight. Al-
ways make sure that the freight is safely locked
on the crane and make sure that there is no risk
of unexpected release or turnover of the freight.
Note.
