My machine is a crane and it works by a pulley and string to get the object up and down. Wind the handle and turn it around and the string will go up or down. The hook at the end of the string is for the lode so it can go up onto the building.

Yes our prediction was right and it had a pulley and the pulley had a hook to make the lode move.
