Note
In time-optimized operation, the crane driver's cabin must not be linked to the trolley because
of the large acceleration change.
The following figure below shows an example of such a travel operation.
Figure 6-45
The trolley initially decelerates from the 60 m position with time-optimized control to -1.7 m/s
(travel from the waterside to land). The target position at 20 m is reached with a pendulum
deflection of approx. 0.8 m. The return travel is restarted shortly after the status bit
"OPEN_GRAB" has been reset. The grab remains for approximately 2 seconds in the target
area of 20 m ... 21 m. The duration that the grab is present within a target area results mainly
from the deceleration. The lower the deceleration, the longer the duration.
The following figure illustrates the unloading:
