Utilisation display (bar graph)
The
Utilisation display (bar graph)
indicates how much of
the admissible load moment (rated moment) is used. As the
rated moment changes constantly during loader operation,
the load moment display also changes constantly.
The utilisation display is marked with differently coloured fields:
green:
"Safe” operation
(0...90% of rated moment)
yellow:
“Prewarning range”
(90...100% of rated moment)
red:
“Overload range” (> 100% of rated moment)

“Pre-warning” light
When this amber display light comes on, this indicates that
the utilisation of the crane has reached the specified pre-
warning range.
An overload situation could therefore be
imminent!
At the same time, the acoustic alarm sounds an interrupted
signal.
For the crane operator, this means that the work can
only be continued with caution.

“Overload” warning light
This red display light lights up to indicate that the maximum
capacity has been reached or exceeded.
At the same time, the acoustic alarm sounds an
uninterrupted signal and, depending on the system wiring,
load moment-increasing boom movements are stopped.
By actuating the key
the acoustic alarm can be
suppressed after a minimum 5-second warning.
