Hi, I'm still pretty new to Flexsim and I'm trying to simulate gantry movement from right to left when a vehicle arrives at a station, then again from left to right after vehicle 1 departs and vehicle 2 arrives at a station. Then process would then be repeated for each subsequent vehicle. The trigger for gantry movement should be when the leading edge of the vehicle arrives at the station. The gantry should stop when it reaches a pre-set point. I think a crane is too complicated for this task, and was thinking a task executor. Attached picture shows a little more detail. gantry-movement.jpg
