Too large difference of
the boom angles at tip
and base boom (if
avail.)
•
The angle as to the horizontal
on the boom head exceeds the
main boom angle by more than
5 degrees.
•
Check angle sensor on the
boom head.
•
Check angle sensor on the
base boom.
E82
Too large difference of
the luffing jib angles at
tip and base jib.
•
The angle as to the horizontal
on the jib head exceeds the luff-
ing jib angle by more than 5
degrees.
•
Check angle sensor on the
jib head.
•
Check angle sensor on the
jib base.
E83
Maximum force in the
main boom pendants
exceeded
•
The force actuating on the main
boom pendants has exceeded
the programmed value
•
Reduce force acting on the
main boom pendants.
E84

tion.
•
The selected rigging condition
is not contained in the crane
data file.
•
Select another rigging con-
dition
•
Check the programming in

position during luffing
jib operation
•
During luffing jib operation the
main boom is not in the pre-
scribed angle range
•

boom defective.
•
Luff boom to the permitted
range
•
Check angle measurement
of the main boom.
E89
Faulty positioning of
the jib during operation
with fixed angle to the
main boom or to a
luffing jib
•
During operation with fixed jib
to the main boom, the jib is not
in the permitted angle range
•
Angle measurement of the jib
defective
•
Luff the auxiliary jib to the
permitted range
•
Verify angle measurement
of the auxiliary jib.
