I am re-posting my coal bin
pics, with more detail. I got alot of PMs requesting more info on my Rolling Coal Bin
. I used 5ea. 1000lb rated wheels. you can find them here:http://www.northerntool.com/webapp/wcs/ ... 0250_40250
All 5 wheels are of the full-swivel type. If I had it to do over again (maybe this summr) I would make 2 of the wheels non-swivel, so the bin
could be pulled more easily by my tractor.
I have about 5800 lbs in the bin
, so thats about 1160lb per wheel. The wheels are EASILY handling the weight.
ALL joints are "Glued-and-screwed". I bought a case of Liquid Nails to use on the bin
. Exterior grade decking screws, from 1 5/8" to 4" are used.
Pic #1 shows the bin
overloaded with rice from Baschak. The top will remain in the upright position until I use a few hundred LBs. There are two trap doors in the front that open INTO the bin
. These will allow me to scoop/shovel coal out once the level gets low. One thing I did not have time to build, was the coal shoot & sliding door in the lower middle. This will be added this summer.
Pic #2 shows a side view, proof-positive there is no bulging of the front or back. Without adding additional framing, I incorperated a little idea of mine. I could tell you, but then I would have to kill you
Pic #3 shows the details of adding the 5 castors. Notice the 4x4 framing has lap joints for strength. Ther are 9 lap joints because I use 3ea. 8ft long pcs, and 3ea. 4ft long pcs of 4x4. The cross in the center of the framing is where the 5th castor is.
Pic#4 shows the back of the bin
, with the Lid-lift-pulley system. The weight is about 5-10 lbs more than the lid, so it will always stay up, unless I pull it down and latch it at the front. During the summer months, I will move the bin
behind the barn, so the rope holding the lid can just be untied and thrown inside the bin
Pic #5 shows my AWESOME Blaschak Rice. No, I did not pick out the sticks and weeds, this is EXACTLY as it arrived.
Any questions, I'll be happy to answer. Or PM me if you want to come over and get measurements if you plan to make your own bin
. Then I'll tell you the secret of how to keep the front and back from bulging without extra framing
