Overload indicators

A manometer with a three-colour scale is provided which indicates the load moment.
During work, the manometer's needle should therefore always be in
the green range of the scale.
The yellow scale section of the moment gauge corresponds with
conditions near 90% of the maximum load permissible.
Deflections of the needle in the red section of the three-colour scale
are indicative of overload. The load moment must be reduced
immediately under such conditions (e.g., by pulling in the extension
arms). It is essential to keep an eye on the load moment indicator
during work so that dangerous overloading of the crane can be
avoided.
When the manometer needle is seen in the red section of the scale,
the load moment must be reduced immediately to prevent dangerous
overloading of the crane.
