How are I-beams rated as far as weight capacity when you mount a hoist and trolley? Mine spans 30 feet,is 4 inches top and bottom,and 15 inches in between.As best I can tell the overall thickness is 3/8 to 1/2 inch thick.It is a tri-post setup.I have a 5 ton hoist on it.So far the heavyest thing I've lifted is my 7800lb. mill.I was extremely careful as all the locals said the beam wouldn't hold up.Actaually I was more worried with the trolley.Everything held up fine,The beam didn't budge,and the trolley did it's job.The hoist wasn't a worry to begin with,at least not for me.These folks I have got me to wondering now though.
