Phil A plate weight in the neighborhood of around 500 pounds. It would seem to me that the Hambro beams would be strong enough to support that much weight, especially if it is distributed over three beams. In St. Louis, I had to construct something in my shop. I had a similar rope hoist as you did. There were no beams I could use. I attached two 4x4 against opposite walls, and a 4 x 4 across the top. An upside down U, with the top beam against the ceiling, which was 8' high. The walls are about 10 feet apart. I did the same thing about 10 feet away. Then I hung a steel beam between the two ceiling 4 x 4', on which the rope hoist would slide. I don't know if this system would work in your shop, but it's an idea. But, again, I think the Hasbro beams shoudl support a plate.
