4. Push the right control lever (1) forward, and hoist the
hook block until it automatically stops (over-winding is
detected).
NOTES
If the hook block is excessively hoisted, the over hoist
detector is activated, generating an alarm buzzer. This
allows the ongoing winding operation to automatically
stop.
5. Change the mode change switch (3) to “Hook stowage”
on the monitor. While the button is pressed or the
screen is touched, the hook is hoisted automatically;
stow the hook (4).
6. Make sure that the crane stowage lamp (1) on the
monitor is lit in yellow.
NOTES
If the crane stowage lamp (1) is not lit in yellow, perform
again the said operation, fully retract and lower the boom,
or slew the boom.
[Automatic stowage]
When automatically stowing the crane, check that there are no interfering objects in the
surrounding area before doing so.
If you feel danger during automatic stowage, immediately stop the operation. Automatic
stowage can be stopped by pressing the emergency stop switch, or by operating the
monitor or crane.
1. When the fully automated stowage switch on the monitor is pressed once, the message
“
Boom will be stowed. Make sure there is no obstacle around the boom.
”
will be displayed.
2. Pressing the fully automated stowage switch once more starts the automatic stowage
operation according to the following procedure.
(1) Hook is wound up until over-winding is detected.
(2) The boom is fully retracted.
(3) The boom is raised to 30 degrees.
(In case boom angle is below 30 degrees.)
(4) The boom is slewed to a 2 degree slewing angle.
(5) The boom is fully lowered.
(6) The hook is stowed.
This completes the automatic stowage.
