I finished framing an addition on a ranch. Now I will open up the kitchen wall to the addition and install a steel beam as the header. My question is: any suggestions on how to lift this 19' long 430lb beam into place, hold it, adjust it into final position and then install lolly columns under the beam ends? I was thinking of muscle onto large saw horses and then adjustable screw jacks, but I think they wont be stable. I also thought about two come-a-longs onto the cathedral rafters and ratcheting it up, then use screw jacks for final adjustment.
