One thing I have learned in this hobby is sometimes you just have to "try it" sometimes it works...sometimes it doesn't.. If you can afford to drop 15 bps on an experiment I would try
it... I doubt that motor would pull a lot of amps just raising and lowering the ramps
I bought two of these to try to run a Bruder conveyor belt... haven't tried them yet....
