GRT8120 OPERATOR MANUAL
OPERATING PROCEDURES

Fixed Length and Intermediate Length
There are lifting capacity tables for main boom fixed lengths
and main boom intermediate lengths.
The lengths are automatically detected by the Rated
Capacity Limiter (RCL), and the corresponding lifting
capacities according to the Lifting Capacity table are enabled
and displayed automatically.
Main Boom Fixed Length
Main boom fixed lengths have the greatest lifting capacities.
A main boom fixed length is reached if:
•
All telescopic sections are locked to a fixed length
•
All telescopic sections are set down.
Main Boom Intermediate Length
A main boom intermediate length is reached if not all
telescopic sections are locked to fixed lengths.
Extend the main boom to the required length before hoisting
the load.
Telescope Picture
The position of the telescopic sections, i.e. which telescopic
section is extended to what extent, is referred to as the
telescoping sequence or the telescope picture.
This section only deals with the displays on the RCL. The
telescoping is also shown on the Operator Display Module
(ODM), refer to
Telescoping the Tele Section, page 4-36
.
The RCL displays main boom fixed lengths and main boom
intermediate lengths in different ways.
Telescoping Sequence
The telescopic sections can only be telescoped individually,
one after the other.
When extending, the operator must always extend the
telescopic section with the highest numbering first, then the
telescopic section with the second highest numbering, etc.
(e.g. T6, T5, T4, T3, T2, T1).
The telescopic sections are always retracted in the reverse
order of extending.
Inspections Prior to Starting Operations
When the ignition is turned on, CCS registers the displayed
telescoping status from the current status of the telescoping
mechanism and the previously saved locking and unlocking
procedures.
Normally, CCS detects differences between the current and
the displayed telescoping and displays the corresponding
error message.
If a malfunction results in saved values being deleted, CCS
can no longer calculate the current telescoping and may not
issue an error message.
Before the first telescoping, compare the telescoping
indicated on the ODM with the current telescoping.
Enabling the Telescoping Mechanism
Push the Boom Telescope Enable/Disable Switch on the left
armrest to enable the telescope function.
The Boom Telescope Enable Indicator in the Status Bar area
(Figure 4-73) of the Operator Display Module (ODM) will
come on (green).
Function of the Controller
This section only describes the function of the control lever.
Before telescoping, a number of prerequisites need to be
fulfilled as well.
The distance between the hook block and the boom nose
changes during telescoping. Ensure that the hook block
does not trigger the anti-two block switch or touch the
ground.
To prevent two-blocking or slack rope conditions, perform the
following functions as required:
•
Lower hoist when extending
•
Raise hoist when retracting.
The controller movements for telescoping vary depending on
the crane configuration. Refer to
CAUTION
Telescope mechanism damage!
If the telescope system position is different from the
current telescoping shown on the display, damage could
occur during operation of the telescope system.
Ensure that the actual indicated telescope status matches
the current telescope position.
WARNING
Risk of accidents due to unexpected crane
movements!
In the case of multiple configuration, check whether the
control lever function Telescoping is switched on before
you move the control lever.
This prevents accidents caused by unexpected
lifting/lowering.
