the bug is already fixed, please use version 14.1.2 of library MultiportalCranes.
I attached the library.
Hope this helps.
you cannot move the hook up to 5 meter, because your portal has an height of 5 meter and you defined the height of the hook as 0.3 meter.
Version 14.1.2 of the crane library is included in maintenance pack 14.1.1 of Plant Simulation.
