I am planning an interior coal bin with fill capability from the exterior wall that the bin is next to. Both the room floor and the outside ground level are at the same level. Bin dims are 116"L x 48"W X 40"H = 6444 pounds = approx. 3.2 tons filled to the rim.
I am planning the 40" height because that is the same height of my Pick up truck bed. So if I cut a hole thru the 16" studs and make it approx. 20" in height. I will have a loading window of 14.5" X 20". 14.5 " should be enough to get a shovel thru comfortably. If I get bagged coal, I hope the bags will fit thru that hole size, that will save some carrying. But the bigger long term plan would be to create a hopper that would fit in this 14.5" X 20" hole. So remove any sheathing cover and insulation and insert the hopper, to be loaded by any small front end bucket loader that I may come across in the future. Kubota BX or the likes. Make the hopper the width of the bucket.
For that 116 " length wall, I am thinking, 2 lower vertical slide feed doors at floor level, 2 doors because of the long length and space them appropriately. There is not enough vertical height for a drop feed. I suppose it will just spill out onto the floor. This is a fab shop , and that is already SOP. When the bin gets low, I can stick a hoe in there and pull it forward. I am attempting this, because I want make things as easy as possible for the future. This bin will be a few steps away from the steel burn box.
One last thought on the 116 length access wall, I am thinking of not permanently screwing the vertical sheathing to the studded wall, so I can remove said sheathing and sneak in there if I need to move some coal around. Also the top which would be 48" x 116", primarily to keep the dust to a minimum. But fab the top in 2 pcs, so (58"x 48") times two. So I can slide one top onto the other, or just remove both as needed. Again, if I need to move /rake/hoe coal around to get it to the feed doors.
I was thinking an exterior bin with a feed door access from the interior, but I do not want to run the risk of frozen coal or the likes
Any comments or suggestions, have at it. thank you, R
oops, scratch the vertical slide doors, I will use vertical openings/top to bottom, 2 of them, and use loose boards placed in said openings as the bin is filled. I must be tired from shoveling coal.
