AMD Track Cleaners
In the past, mines transported their raw product in drop bottom and side dump cars. Dirty tracks were the norm. As the mine car doors began to wear or otherwise fail to seal tightly, coal sifted from the cars onto the track. Material build up became so bad between the rails that motormen found they could pull fewer and fewer cars in their loaded trips due to contact with this material. Not only did this situation require more trips to haul the same load levels, but the cost of mine car maintenance skyrocketed. Without the use of our efficient Track Cleaners, it required a significant number of personnel and higher resulting labor costs to clean the tracks by hand.
In the early 1940's, American Mine Door introduced the first machine designed specifically to clean the haulage road in underground mines. Prior to that time, and for some years after, master mechanics would try, often unsuccessfully, to adapt old loading machines to clean track.
Many track mines remain in use around the world, and American Mine Door's rugged, heavy-duty track cleaner is still the best way to clean track. Designed to operate in coal, metal, and non-metal underground mines, our Model 75 Track Cleaner is successful in removing Iron, Copper, Coal, Lead, Potash, and Salt from your tracks.
AMD Mine Doors
Prior to the introduction of automatic mine doors, mine operators used trappers to open and close doors on the haulage road, so that the motorman would not have to stop. His snapper would open the door - wait for the last car to pass, then close the door and run to get on the end of the trip. In practice however, often times the motorman would not stop, he would only slow down so the snapper could run ahead of the locomotive and open the door. Yes, they really did have miners crazy enough to employ these tactics. As you can see automatic doors were not only an economic innovation but a safety innovation as well. American Mine Door's custom mine doors provide economical, safe, efficient, practical ventilation control for all types of track or trackless mines, including mines for coal, uranium, salt, gypsum, clay, gold, potash, titanium, and molybdenum.
