Forklifts and Elevators

I want the forklift to load the box in the elevator directly and the elevator goes to the second floor when another forklift to unload the box from the elevator and store it

is that possible without using intermediate queues for loading and unloading?

You can achieve the behavior your prescribed by using Process Flow to move the items into the elevator, tell the elevator to travel, and then pick up the items at the top. I created a simple example that should give you ideas.

@tanner.p, Decrease the inter-arrival time of the source (to be 5 as an example) and you will like what will happen :D .. I appreciate really your first answer that has been removed although the synchronization between conveyor and elevator can't be established but it was a brilliant one .. I am thinking of putting the intermediate queues overlayed on elevator on each floor and use the triggers to close and open their ports..

Thanks for the feedback. I see what you mean now. This problem should be able to be resolved by adding a Zone with max content of 1 in Process Flow. I have updated my previous example to include a Zone and now only one token can be processed at a time, which eliminates the problem with the Transporter trying to load the Elevator prematurely. Hopefully this helps.
