7.3 Failure of electrical system / electronic system (ex-
treme case)
Danger!
A danger of tilting is existent due to boom movements,
which increase the load moment! In case of failure of
the electrical / electronic system these locking devices
are out of function! Therefore always the telescope must
be retracted completely as first step. When carrying out
emergency lowering you have to take special care!
If the working cage cannot be moved safely into a posi-
tion, in which a safe leaving of the working cage is pos-
sible, the fire brigade must be called for the rescue of
the cage crew.
Attention!
The boom and boom rest will be damaged by the move-
ment „Extend telescope“ if the boom is in the boom rest
and locked by the bolt. The telescope must not ever be
extended while in this boom position. First raise the
boom, and then extend the telescope.
