Finnmossen Mines Hoist – C. A. Ångström 1860

Construction and Power Source

The hoist was built by C. A. Ångström in 1860. Its power was provided by the existing waterwheel already in operation, which supplied the Finnmossen Mines with mechanical power.

Connection to the Waterwheel

To avoid interrupting the operation of the waterwheel, the hoist could be engaged and disengaged while running. Ångström used a friction clutch (D), which allowed the hoist to start smoothly and without jerks, unlike the more common pawl couplings of the time.

Hoist Line and Ore Drum

The hoist line from the waterwheel to the Finnmossen Mines was approximately 720 meters long. The ore drum descended under its own weight, and its speed was regulated with a brake on the hoist frame.
