Please let me know if anybody know about this problem.

thanks

Right now, FlexSim CT cannot do this visually. But you can input factor in "Speed Tag" column of hatch profile table. Here, you can double the quay crane operation speed, then you can get the same simulation result as tandem lift.

Hi Hao Zhou,

So, there is no way to do about this ? Ahh .... Can i do customize control in crane parameters with any programming?
Thanks.

You can do as I described here. But there really are a lot of stuff to do. In CT, right now, in my opinion, there is no easy way of having a customized quay crane.

Hi Hao Zhou,

Let me ask you 1 question.
Do you know how to pick up 2x40ft containers with one hoist? where can i modified flexscript ?
thanks.

Sorry for the late replay. I would say there is no way to customize quay crane right now. You can check the tree for quay crane. Most of useful customizing trigger are used by dll already.
I would suggest two way:
1. Use speed tag as I show before.
2. Find the spreader object in the tree of quay crane. Copy it, paste it under the original spreader, set right location for the second spread. Then, in the ondraw trigger of quay crane, you draw another container in the right position when you load and unload container by command drawbox(). Also, you need set right position of second spreader in the ondraw trigger also. In this way, you can visually have tandem lift.
