I won't email an answer to you, but happy to post one here. I am not a fab guy by trade, but I have worked with metals for years and have done some on-the-fly repair work using available tools. First a question in response to your statement "no hydraulic". Your description leads me to think this is a farm or ranch environment (barn). So, you do not have any hydraulic jacks laying around to lift equipment for repairs? Next, depending on where on the ladder the bends are that you want to repair, is there anyway you can lay them on a concrete slab with the bend up and place a timber on top of the bend and drive a truck on top of it? You could also use a combination of chains, boards, and a hydraulic or even mechanical jack to apply force to bend the pipe.
