Size and alignment of the fields for crane-to-crane collision protection
The crane-to-crane collision protection can be used
when the installation position and the
resulting inclination angle of the laser scanner allow this. Laser scanners with strong
inclination angles can only scan between the neighboring cranes to a certain degree. This
means a necessary stopping field cannot be completely covered.
A suitable layout for a stopping field can therefore not be determined. That is why the
evaluation cases and the stopping fields for the crane-to-crane collision protection are
predefined, but their geometries are not yet defined (empty).
The stopping fields should be wedge-shaped.
Due to the crane movements during operation, a suitable distance of the stopping field
to the crane body must be considered (distance
d
in the following figure). A minimum
distance of ≥
0.5 m is recommended.

If the distance is too small, the monitoring field will impinge on the crane body and trigger
a stop erroneously.
