A piece of machinery of that size and shape would be quite easy to move, and without risk. Seeing the photo reminded me of the time when we used to move large boats on greased ways and in particular, the time we moved a 30 ton yacht with a very deep keel and the point of balance right at the forward end of the very rounded keel.
I had a few more grey hairs after that boat was moved and safely blocked off. No elf’ n’ safety in those days. !!
