5.1.1.B Work Area Definition
The
work area definition system helps the operator to define the crane’s working area. This is done by
creating vertical wall(s) that can represent obstacles (i.e. buildings, towers, poles, etc.) in the crane’s
working range. The wall(s) are set by defining points with the boom tip along the outer limits of the
operator’s work area, see setup procedure below. Because these walls are defined by the operator
and are not “actual real” walls, we refer to them as
“virtual” walls. When setting the walls, always
keep a safe working distance to any obstacles. Never work outside a safe working area as
outlined by common practice, standards, and manuals.
A virtual wall is set by defining two points. To prevent inaccuracies when defining the two points for the
virtual wall, use the following to rules:
1. The two points should be the same distance form the obstacle.
2. Set the two points at the maximum distance apart, which can be safely reached by the boom tip.
The operator can setup up to 5 virtual walls, the first wall is defined by a straight line between two set
points. The second through fifth walls are created by one new point and the previously selected point.
After the walls have been set, the system alerts the operator when the boom approaches them. This is
done both visual and audible. The console will warn the operator by an audible, beeping alarm which
increases in frequency as the boom approaches the wall. At the same times, the control light
“Alarm
Stop” (refer to no. 6, Chapter 3.3 of the operator’s manual) will come on and the button “LIM” (refer to
no. 8, Chapter 3.3 of the operator’s manual) will be lit. Similarly, the “virtual wall” symbol in the main
screen blinks. If the boom crosses the wall the audible alarm becomes continuous. See the Pre-
Warning System Section for information on how the pre-warning system is defined.
THERE ARE NO CUTOUTS ASSOCIATED WITH THE WORK AREA DEFINITION FEATURE.

On entering the work area definition
function, the crane working area is
displayed. A blinking X indicates that
a point may be set to define a wall.
Move the boom tip to one end of the
virtual wall you want to set.
