11.5 Working range limiter
You can set and monitor four different limits in the working range limiter
submenus:
– A maximum overall height
– A maximum working radius
– A maximum slewing angle
– Objects in the working range
The monitoring of the programmed limits can be switched on and off
separately.
G
Risk of accident due to situations which cannot be monitored
The working range limiter only serves as an additional safety device. Brake
the crane movement before contact with the obstacle becomes imminent.
Do not deliberately move into the shutdown range. You, the crane opera-
tor, are still responsible for monitoring the working range, so that you can
react appropriately if situations arise which cannot be monitored electron-
ically.
G
Risk of accident due to limits set too low
When entering the limit values, bear in mind that, even after switching off
the engine, movements can still occur that would bring the load into the
shutdown range (e.g. due to the load swinging or the boom bending). For
this reason, always enter the limit values with sufficient safety distance to
the object.
G
Risk of accident due to insufficient safe distances
Always observe all safety distances in accordance with the national legal
regulations (e.g. concerning electrical cables) even if the working range
limiter is switched on.
