If you are going to put a 2,000 pound load on a cable, it needs to have a breaking strength of 10,000 pounds. It's called "working load" and "nominal strength". That being said, most casters are rated in working load.
In China they do it a little different. Something rated at 500 pounds can hold 100 pounds safely
Buy good wheels. Great idea though! Too bad you can't just move some stuff around to make your coal bin bigger and avoid all the extra work.
