I need to build a hoist system, and I plan to have two arches with two hoists, starting with two pairs of vertical 6x6" wooden posts. On the top, I need two beams that span all the way across, which is no more than 15 feet, and I need for it to handle a minimum of 1,000 pounds, with 2,000 being better. I need to know that if I get a particular size of beam that it is unquestionably strong enough. I cannot figure out where to find this information. I have tried all the steel yards and lumber yards around here, they're all afraid of getting sued or something, or maybe they just really haven't got a clue.
