Simulate the movement of a dock crane

Hi everyone,

I am trying to model the movement of a crane. Not the standard gantry crane that comes with flexsim but a dock crane that allows rotation as can be seen in the animation created in the model. The crane is made up of three different parts and has been modelled as a Basic TE. It should be able to lift the five items, one at a time (with the hook), from Queue1 and carry them to Queue2. Besides, every item should be placed in Queue2 in a specific point since they will be part of a whole structure (see the final structure in the model)

As I said, I tried to model the crane as a “Basic Task Executer”, and by means of an animation to simulate the hook going down to pick up the items.This crane can perform 3 types of movements (as shown in the animation created within the model).

The complexity for me is to pick up the item at the right moment when the hook is located at the lowest point of its path. I was wondering if the best would be to use a Task Executer Process Flow…

Finally, I am not sure how to approach the positioning of the items at Queue2, as all five items have different shapes and sizes.

Thanks in advance for helping me out with this one.

Could you try using the Robot object as a base model instead. You can edit the 3D objects of the parts of the robot, and replace them with the 3D objects of your crane. Or if you need it to move, you could look into an object like the Transporter (forklift). Since it has the animation of loading and unloading.

I don't know if this is what you're looking for, but here's the article that explains how to set up and use animations:
