Local building code requires your roof to be designed to support 150 pounds per square foot. While I would not want to test it, my set up with the 2 inch pipe being supported by 6 trusses would be able to hold over 6 tons of weight. In theory if my winch was strong enough I could pick up my truck with many pounds to spare. So unless you are cutting trusses or rafters, I would not worry about the weight your adding to the attic floor or stress your putting on the roof trusses. So far the heaviest thing I lifted was my motorcycle at 800 pounds. And I even measured the change on the trusses as I was interested if they moved. I used a point on the trusses separated by 19 feet 6 inches. And with the bike in the air and myself standing directly on that trusses bottom joist it moved a total of zero.
