i want to put a steal beam in the garage for lifting engines and anything else, but not sure what size I need. I've searched the web, but cannot find anything that allows me to punch in the dimensions I'm working with to get an answer, without adding in numbers for deflection and static load crap that I have no idea what it is. All the forums I've read where somebody suggests a certain size beam, has a safety Steve pop up and totally negate the previous persons recommendations because his safety factor wasn't high enough for the load he's lifting. Specs I beam that will accept a chain hoist trolley 15' span And can be up to 8" high Would like to have a 2000lbs lifting capacity. Anybody got any leads for me?
