    Thanks for your reply, Ruben. Not the most efficient method! I recall, that Italy used to use electric locomotives with 3 phase asynchronous motors. (2 phases via overhead wires, the 3rd one via rail). They used tubes filled with water as variable resistors. The water vaporized and had to be refilled frequently. (Something like 'electric steam locomotives :-)
    Greetings Harald

    Yes, 3 phase. In this case it seems they controlled the speed by changing the rotor's resistance.

    The discussion and background information is even more interesting, than the image! How did they manage to control speed of the winder with an asynchronous motor. (3 phase, I assume)?

    Haiko, there are many headgears over here with this design and GHH also, they are from the late 40s or early 50s. I noticed what you say when I watch the pictures of headgears in Germany. Thanks for the info, I take note. The metal mechanical company that build most of them is soposed they had links with german companies on the 40s; I know it because I worked for them and I saw some documents and old drawings. Over here there are also four that are absolutely different to any other I've ever seen on the pictures of central Europe or UK.

    El mundo es un pañuelo: the headgear seems to be of Dörnen design which happened to be a steel construction company right here in my city, Dortmund. Dörnen was specialized into headgears, blast furnaces and bridges but saw its final days many years ago. Incidentally, I went there just days ago just to find their main workshop building freshly gone.

    Now, this is something I've never heard of before. Perfectly logical, but quite astonishing nonetheless.

    Alan, the winding engine is english made and has two drums and it was ran by an English Electric asynchronous motor which is strange over here. I only know another EE one in Asturias. It seems to be from the 50s. At the collieries over here, most of them were german made by Siemens with DC engines. The winding engine is into a hall at the first floor of the machine house you can see on the picture just infront of the frame. Below the winding engine there is a set of transformers and control panels EE as well. I will send out to your mail more detailed pictures. This pit was quiet unusual, It was on top of a mountain, with a very difficult entry, they did not pull up to the top of the mountain the coal through it; they pulled the coal down to the valley level where there was an entrance close to a road. I hope I made myself understand. I don't know if you know this valleys, they are very narrow, flanked by mountains. At the beginning they started the mine from the bottom of the mountain and they carried on extracting the coal going upwards and at the last level they used to bore a hole and install a frame with pulleys to bring downwards from the upper levels to the main entrance the coal.

    This looks as if it could have been a vertical winding engine, with the drum above the engine. Do you have any more information about it or any close up pictures please?

    Right in the middle of the woods. How charming. :-)
