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 two 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 set up to 5 virtual walls, the first wall is defined by a straight line between two
set points. The second through fifth wall is 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.
