Flatrod system

The flatrod system (German:Kunstgestänge, Stangenkunst, Stangenwerk or Stangenleitung) was an invention of the mining industry that enabled the mechanical movement generated by a water wheel (German: Kunstrad) to be transferred over short distances. They were invented in the 16th century and by the 18th century they were being used to transmit power up to four kilometres. They were widely used in the Harz and Ore Mountains of Germany as well as in Cornwall, England and Bergslagen in Sweden.
