24. Crane operation
If the voice warning message "Caution when slewing" is emitted and slewing begins
automatically decelerating, try to stop slewing manually by operating the slewing lever in the
opposite direction, while paying attention to the movement of the load. Waiting for slewing to
stop automatically could result in not stopping properly and overrunning the overload point, if
the machine is not level or if there is a strong wind.
(541A-0230-1E)
3) Automatic stop and corresponding warning
When reaching the position (angle) immediately before the
overload point, slewing will automatically smoothly stop and a
voice warning message "Danger maximum lifting capacity" will
be emitted (one time). Just before stopping, a warning chime
(
"DING DONG DANG DONG,
…
"
) is emitted (
continuously
)
to notify the operator that the system is functioning. If the
control lever is operated in the opposite direction and the crane
is slewed away from the overload point
(angle), the warning
chime will stop.
