This rebuilt coiler shows an early form of conveyor technology. It was used when the shaft was not too deep (up to 25 meters). Haspelknecht wrapped the hauling rope on the wooden drum with large cranks and thus pulled out conveying vessels with a weight of approx. 120 kg.Daily breaks are visible in the forest behind the reel unit: collapse points of old mine mines that form depressions on the surface of the earth.
