3. Fetching or bringing a container from the ship
This procedure can be performed in parallel with step 1 and
step 2.
The SIMOCRANE Sway Control System covers the following
functions here:
•
Time-optimized, reliable and automatic motion control of the
trolley and hoisting gear.
•
Closed-loop control of load swaying.
•
Closed-loop control of the angle of rotation of the load
(skew control). The skew controller sends the setpoints for the
trim, list and skew cylinders to the crane controller.
Note
:
The control solution for the individual cylinders must be imple-
mented in an application in accordance with the type of me-
chanical system installed.
When this is combined with acquisition of the height and hin-
drance profiles by means of an appropriate distance sensor
system, performance and collision avoidance can also be
improved.

4. Putting a container down on the truck
The decisive factor in this step is accurate interplay of the
SIMOCRANE components used.
•
The load position is determined by the SIMOCRANE Sway
Control System and it is output at the interface for the crane
controller.
•
The target position is determined by SIMOCRANE TPS and it
is output at the interface for the crane controller.
•
The crane application can determine the setpoints for the final
positioning operation from this. With this information,
SIMOCRANE Basic Technology controls the relevant axes to
complete the positioning operation.
•
If skew control is implemented, this is also controlled by the
crane application. The corresponding setpoints are deter-
mined here on the basis of the load and target position data.
