Water system
The Amber Fort had an elaborate water system, of which the wooden machinery in this room is just a small part. This mechanism is a pump. A donkey was attached to the horizontal bar bottom-left, which then walked around the vertical shaft - turning it in the process. The spiky looking thing under the ceiling works like the differential under your car, and transfers the drive to the horizontal drive shaft that disappears out through the oblong hole in the far wall. It has a wheel attached to it, around which runs an endless rope with leather cups attached to it, for lifting the water. The ropes (which can be seen through the arched opening) hang down a shaft to the water below (lifted from still further downhill by other pumps I believe).
