GRT9165 OPERATOR MANUAL OPERATING PROCEDURES
A working crane may settle during lifting operations.
Frequently check the crane for level. When rechecking the
crane for level, the boom must be positioned over the front of
the crane, fully lowered to horizontal and fully retracted, and
the cab must be in its fully lowered position. If necessary,
level the crane again following instructions in the section
Using the Outriggers, page 4-21.
Using the Outriggers
Outriggers are extended and retracted from the Operator
Display Module (ODM) in the cab [refer to Using the
Operator Display Module (ODM), page 4-72].
Setting the Outriggers Manually
NOTE: ECO mode does not work when operating the
outriggers.
1. Enable the outrigger functions by doing the following:
- Shift transmission to neutral
- Engage the parking brake
- Engage four-wheel drive
- Disable all crane functions
- Fully lower cab
2. Position the outrigger pads directly out from each
outrigger to where the outriggers will be properly
extended.
3. If required, extend the outrigger beams to the
mid-extend or fully extended position using the
Outrigger Extend/Retract Switch and the Operator
Display Module (Refer to Extending/Retracting the
Outriggers Beams, page 4-102).
Refer to Engaging the Outrigger Mid-Extend Lock Pin,
page 4-23 if the crane is to be operated with the
outriggers at the mid-extend position.
NOTE: More than one outrigger beam can be extended at
a time. To make sure each outrigger is fully
extended, repeat step 3 for each outrigger after a
multi-outrigger extension.
4. Extend the outrigger jacks using the Outrigger
Extend/Retract Switch and the Operator Display Module
(ODM).
Refer to Extending/Retracting Individual Outrigger
Jacks, page 4-103 to operate individual outrigger jacks.
Refer to Extending/Retracting the Outrigger Jacks - x4,
page 4-104 to operate the four jacks at the same time.
Extend each outrigger jack until the locking levers of the
pad engage the jack cylinder barrel.
5. Extend the jacks as necessary until all tires are clear of
the ground and crane is level as indicated by the
inclination indicator located on the ODM screen
(7, Figure 4-97).
DANGER
To prevent serious injury or death, keep clear of moving
outrigger beams/jacks.
DANGER
Death or serious injury could result from improper crane
setup on outriggers.
WARNING
Be sure the outriggers are properly extended and set, and
the crane is level for operation on outriggers.
All four outrigger beams must be equally set to the fully
retracted position, mid position vertical stripe, or fully
extended position before beginning operation. Mid
extended outriggers must be pinned (locked) in position.
WARNING
When operating the crane on outriggers, the outriggers
should always be extended and set in the proper position
corresponding to the load capacity chart to be used.
DANGER
Tipping Hazard!
All four outrigger beams must be deployed to one of three
positions before beginning operation, which include fully
retracted, mid-extend, or fully extended. Do not operate
the crane with the outriggers in any other position.
