I bought these to load and unload a 55 gallon drum of fuel (GAS) for my farm equipment. With one at each end of the barrel, lift and hold it. very good. I also have a 35 gallon fuel tank that I use for the same reason. So my overall take on these belts is that they are strong enough that I don't have to worry about them breaking and injuring myself, not to mention the $3.39 per gallon fuel cost. They pay off in just one uneventful climb. And they're flexible enough not to be a problem. I would buy them again. Many Thanks.
