Using Translators

I’m using TM to render a video from Revit. I’m making a crane run along rails and I also want to be able to make the forks move up and down during the run. I have tried to include a translator in another translator, but then only the first one work, the one located in the main translator is stopp.
It would be a really cool addition to be able to have two Translators on the same object. For example, a forklift that drives forward and lifts pallets into a truck.
