GRT8120 OPERATOR MANUAL
OPERATING PROCEDURES
4
2.
Pull inner controller on right armrest rearward and hold
to raise the boom.
3.
When boom angle gets to the desired elevation, let
controller return to the center (neutral) position to stop
boom lift function.
Lowering the Boom
Dual Axis Controllers
1.
Push the Boom Lift Enable/Disable Switch on right
armrest to enable the boom lift function.
The Boom Lift Enable Indicator in the Status Bar area
(Figure 4-73) of the Operator Display Module (ODM) will
come on (green).
2.
Push controller on right armrest to the right and hold to
lower the boom.
3.
When boom angle gets to the desired elevation, let
controller return to the center (neutral) position to stop
boom lower function.
Single Axis Controller (Optional)
1.
Push the Boom Lift Enable/Disable Switch on right
armrest to enable the boom lift function.
The Boom Lift Enable Indicator will come on (green).
2.
Push inner controller on right armrest forward and hold
to lower the boom.
3.
When boom angle gets to the desired elevation, let
controller return to the center (neutral) position to stop
boom lower function.
Telescoping the Boom
The GRT8120 is equipped with a 7-section Twin-Lock boom.
It has six telescoping sections that can be extended or
retracted independently from one another. Each telescoping
section has locking positions at 0%, 50%, 92% and 100% of
extension.
Within the boom there is a single-stage hydraulic cylinder. It
can be extended or retracted by enabling the telescoping
function and commanding motion using the controller. See
sections on
Extending the Boom
or
Retracting the Boom
for
operational information.
Three interfaces are provided for telescoping the GRT8120.
In n or m al op era ti on t he o pe r at or c an s el e ct f r om

or

.
If necessary, the
Emergency Mode
can be used to perform maintenance on
the boom or correct issues with the telescoping operation.
Descriptions of the telescoping modes
•
Semi-automatic Mode
is the preferred method for
telescoping because it requires the least effort from the
operator. The operator inputs the telescoping sequence,
or “tele picture” into the Operator Display Module (ODM)
by entering the locking position for each of the six
telescoping sections. The Crane Control System (CCS)
determines the order of operations required to achieve
the entered telescoping sequence. To increase the
boom length, the user moves the controller in the extend
direction. To decrease the boom length the user moves
the controller in the retract direction. When the boom
s ec t i on s ar e m o v i ng th e i r sp e ed i s c on t r o l l ed
proportionally to the command given by the user. The
CCS slows telescoping motion when the boom section is
nearing the target locking position.
NOTE:
Some movements of the telescoping cylinder are
automated by the CCS. When CCS is controlling
the movement of the telescoping cylinder a moving
series of dots is displayed on the ODM.
•
Manual Mode
is a method of telescoping preferred by
some operators because it gives them more control over
the telescoping process. In this mode it is not necessary
to enter the target telescoping sequence prior to starting
the process. Rather, the operator can unlock the
telescoping cylinder and position the telescoping
cylinder within the boom using the controller. When the
telescope cylinder is within range to engage a boom
section the symbol for locking the cylinder appears. The
operator moves the telescoping cylinder to the desired
boom section and then selects the symbol for locking the
telescope cylinder. The CCS locks the telescoping
mechanism to the boom section and then automatically
DANGER
Crushing and/or Tipping Hazard!
Keep area beneath boom clear of all obstructions and
personnel when lowering boom.
Long cantilever booms can create a tipping condition,
even when unloaded in an extended, lowered position. Do
not lower the boom below the minimum boom angle
shown on load chart.
DANGER
Two-Block Hazard!
To avoid death or serious injury, keep load handling
devices away from tip of boom or boom extension when
extending or lowering the boom and when hoisting up.
When lowering boom, simultaneously let out hoist rope to
prevent two-blocking the boom nose and the hook block.
CAUTION
The closer the load is carried to the boom nose, the more
important it becomes to simultaneously let out hoist rope
as boom is lowered.
