Two of the track trollies do turn and two seem to be seized up and the pulley does spin. I do not see any cracks in the cast-iron.
At least two of the trolleys seem to be offset but whether that is by Design or other reasons, I do not know. It's hard to imagine that the cast iron could Bend without cracking however I just don't know for sure. There is rust on it and it is not new and certainly shows signs of use and age.
