10.7 Working range limiter
You can set and monitor three different limits in the working range limiter
menus:
– a maximum overall height,
– a maximum working radius,
– a maximum slewing angle,
– a limited rope travel.
The monitoring of the programmed limits can be switched on and off
separately.
G
Risk of accidents 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
electronically.
G
Risk of accidents 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 area, e.g. due to the load swinging or the boom bending. For this
reason, always enter the limit values with sufficient safety margin from 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 overhead power lines) even if the working
range limiter is switched on.
