Hey! I have been thinking about this and I was wondering what other people think. As answer on the question, you can name any crazy idea that pops up! Or maybe something that we already know/have in our world.
One common method for transporting heavy objects involves using animals like horses, oxen, and mules to pull carts or wagons. This approach has been utilized for centuries and remains in use in certain parts of the world today. Another method involves human labor to carry heavy items, which is still prevalent in many areas where motorized vehicles are not available.
Alongside these traditional methods, there are several other ways to transport heavy objects without using motorized vehicles. For instance, bicycles or tricycles with large cargo baskets or trailers attached to them can be utilized. Additionally, boats or ships can be used to transport heavy objects over water. Finally, cranes or pulleys can be employed to lift and move heavy objects, though this approach requires specialized equipment and is typically used in construction or industrial settings.
In fact what you propose already happened. Roman engineers were experts in using simple machines to lift weight, which continued in the Middle Ages.
