The force of the water was transmitted from the turbine to the factory machines by means of an ingenious mechanical transmission system, which is generically known as a transmission shaft. Each factory had its own transmission shafts and they were either highly complex or extremely simple systems. However, the ingenuity of the technicians and mechanics of the factories was always on hand. Operation and maintenance were essential aspects in the factory, and the turbine mechanic and the greaser were responsible for these tasks. The operation of the factory was totally dependent on their work.
