Displays During Crane Operation
The following information is constantly displayed in addition
to the displays of the rigging mode:
Current Overall Height
Overall height is the approximate vertical distance between
the lower edge of the outrigger pad and the highest point of
the main boom or lattice extension. The displayed value
(1, Figure 4-195) applies to fully extended outrigger
cylinders on the largest outrigger span.
The value is displayed either in meters (m) or in feet (ft),
depending on the setting.
Current Lattice Extension Angle
- Lifting/lowering lattice extension: Shows the
current lattice extension angle (1, Figure 4-196) in
relation to the main boom in degrees.
- Lattice extension, can be angled: Shows the
angle of the lattice extension corresponding to the
RCL code in degrees (1, Figure 4-196).
If the displayed RCL code does not apply to a lattice
extension, nothing will be displayed.
Counterweight Installed
Shows the counterweight (1, Figure 4-197) in tons (t).
