Checking the
wind speed
Strong winds can result in the truck crane becoming overloaded.
• Prior to and during crane operation, check whether the current wind
speed is lower than the maximum permissible wind speed.
Maximum permissible wind speed
The maximum permissible wind speed (1) for the current rigging mode is
specified at the bottom of the corresponding
Lifting capacity table.
In certain cases, the specified permissible wind speed must be reduced;
à Lifting capacity table.
Current wind speed
The current wind speed is displayed in the main menu and in the
Telescoping
submenu. The colour of the bar (1) changes depending on the displayed
range:
H
The colour of the bar only depends on the value of the current wind speed.
The maximum permissible wind speed does not affect the colour of the bar.
If an anemometer is not available, or in the event of a fault, you can find out
which speeds are forecast by contacting the relevant weather stations.
The
Lifting capacity table contains an overview of the wind strengths, wind
speeds and their effects.
If the maximum permitted wind speed is exceeded
No automatic shutdown occurs if the maximum permissible wind speed is
exceeded.
• Immediately cease crane operation.
• Put the truck crane into the rigging mode specified for the current wind
speed in the
Lifting capacity table.
0 to 6 m/s: Green bar
6 to 12 m/s: Yellow bar
Over 12 m/s: Red bar

Risk of accidents due to excessively high wind speeds!
If the current wind speed is higher that the maximum permissible wind
speed, immediately stop operating the crane and set up the corresponding
rigging mode
Lifting capacity table.
This will prevent the truck crane from overturning due to overload.
