GRT8120 OPERATOR MANUAL OPERATING PROCEDURES
4
The Virtual Walls Limitation Menu allows the operator to
define up to five walls or barriers in which the boom is not
expected to operate.
Table 4-9 lists the WRL Limitation Screen Symbols.
Defining the First Virtual Wall
To define and enable the first Virtual Wall (assuming no
Virtual Walls are already defined), the following steps can be
used:
1. Select the Virtual Walls Limitation Screen
(6, Figure 4-108) on the Main Menu Screen (and in this
case there would not be any virtual walls shown as
defined or active) as noted in the Virtual Walls Number
(1, Figure 4-113). (Note: The number “1” indicates the
number of virtual walls and can be up to “5” five virtual
walls defined.)
2. Position the crane so that the hook is located at the
position to define the first (start) point of the Virtual Wall
(Point A or Symbol 2).
3. Use the Right Arrow (4, Figure 4-62) Function key to
highlight the Accept Crane Position Point A Symbol (2),
Figure 4-113.
4. Use an OK Button (5, Figure 4-62) to accept the current
crane position to be Point A (2). The location of the point
should now be shown on the screen with a label of '1a'
as indicated in the yellow box in the sample in
Figure 4-114.
5. Position the crane so that the hook is located at the
position to define the second point of the Virtual Wall
(Point B), or Item 3 (Figure 4-113).
NOTE : The two
points may not be so close to each other that a virtual
wall is not clearly defined. The two points should be at
least 10 ft apart.
6. Use the Right Arrow (4, Figure 4-62) Function key to
highlight the Accept Crane Position Point B Symbol
(3, Figure 4-113).
7. Use an OK Button (5, Figure 4-62) to accept the current
crane position to be Point B. The location of the point
should now be shown on the screen with a label of '1b'
as indicated in the yellow box in the sample
Figure 4-114.
NOTE: As each Virtual Wall is defined, you will have a wall
number and “a” and “b” defined for each wall.
NOTE: The screen should also show a “forbidden zone” for
the area beyond the Virtual Wall. Use a visual
inspection of the screen and the area around the
crane to verify that the Virtual Wall is providing the
desired zone correctly. Also, note that the boom is
now at the wall limitation, so alarms will sound. The
boom can now be moved away from the wall to
cease the alarm.
8. The Virtual Wall #1 is now defined and enabled. Crane
operations can be resumed with the WRL working with
this specified limitation.
NOTE: The Virtual Wall Number 3, as shown in the
EXAMPLE in the orange box in Figure 4-114,
increments if the second wall was just defined, so
that it is ready to define a subsequent Virtual Wall,
if so desired.
