The winch is a machine built to exert, through a rope, high traction forces, vertically or horizontally, respectively to lift or drag loads.
It consists of a drum with a horizontal axis around which the tow rope is wound and a set of gear reducers that slow the rotation speed and transmit motion from the input shaft, operated by hand or by a motor, to the drum.
In this site shaped like a “chamber,” the winch was housed, whose rope, using the hole appropriately made high up in the wall on the exterior side through a deflection pulley, went down into the shaft.
No documentation has been preserved on the winch present here that allows giving more details.
