In the center of Kärrgruvan, there is a sign showing the way to Polhemshjulet. It is placed in a middle of a crossroad and it is easy to take the wrong way. If you are driving towards a 30 km speed sign, you are chosen the wrong way. A down hill road is leading you to a parking place for this interesting wheel structure. Here you can read about this flat road construction. It is astonishing what power one could

get out of this 15 m "water fall".
Technically it was only 15.2 ps, but the moment was immer larger. These flat rods could transfer the movements several km. This one had a length of 1306 m long. The wheel got it's working water on top and this had the effect that the total weight in 70 bags filled with water times lever gave the moment/force. In order to lead the water from the nearby Bålsjön a 3 km long channel was dug. This is still left but with only a small amount of water. The last connection to the wheel through was a chute. In the end of  the dug channel there is still the   arrangements for connection to the wheel. By some occasion it has burned. This kind of dug channels are not unusual. A still working channel with water, can be seen in Bredsjö between Kopparberg and Hällefors. Although the mark owner have cut down all trees on the channel sides. This will condemn the channel in some years. It is important that societies watch their area history and look after of what are left behind. Market owners don't care. The crankshaft gives the flat rod a stroke of 1.8 m. Here the rods are connected. Of course it was very important not to allow play in every connection. The total play could decrease the stroke noticeable. Look at the picture and understand the construction.  Stroke length is also lost when the rod is hanging down. Look at the genius construction for it's time of the cardan joints. These didn't allow any play. This was a work by the local black smith. The mounting is very simple. This flat rod was built 1877 and was i use till 1920. This despite that steam engines already were used from 1850. Nevertheless because it was cheap with water power. Electricity came to Norberg 1897. These types of flat rods could only be used for pumping out water from the mines. This because of the forward and resverse movements. Bringing up ore was normally made by horse mills or when not so deep mines just by carrying the ore up to zero level.
