The coal truck chutes the wet coal (no dust!) through the basement window into the hanging bag permanently mounted to each skid. As each skid gets full, we put another skid under the window. We have 5 skids, 4 of them will hold 5 tons total, which empties the coal truck.
Each skid has 2- 14" x 24" x 3/16" thick steel slide gates. The slide gates can be shut off at anytime to remove skids from the floor auger box.
