ADDITIONS
1. Working Range Selection
It senses the position of the crane boom in relation to the front center of the crane chassis (working area). In case
there are varying capacity charts for different working ranges an automatical change from one range to the other is
given.
If there is a prohibited working range an alarm light will come on and the horn will sound at any time the crane swings
out of the permissable working area.
2. Angle Preset
For a specific condition, a working range in dependence on boom or luffing jib angle is settable by this equipment.
If the maximum actual angle is higher or the minimum angle is lower than the setted one the alarm light will come and
the horn will sound.
