Have you worked with logs in building?

Help!!!! We are in the middle of a living room addition, and the rafters and such are with logs. The business with the boom truck to lift them onto the framing can't help (truck down), so we need to find a way to get those logs lifted. Any suggestions?

Are the logs milled like R/R or square beams or heavy timber logs, I use a duct lift on milled logs you should be able to rent one but check the capacity, this only works on a level surface.

Lodge pole pine- not milled at all. No rentals around here- remote area.

Sounds like it's gin-pole time. I was lookin' for just such an article a few days ago and saved it to the hard drive, for future reference... http://www.forestryforum.com/board/i...?topic=30792.0 if your lifting just one beam, you might not have to go so 'big' on the gin pole.

I've lifted mongo beams by bolting or chaining a pole slightly longer than the height needed, next to the 'delivery point'... tie a rope or chain around it and winch it up with a come along... set it in position and attach it securely, but not permanently, then do the same on the other end... adjust... and fasten permanently, then do the same with the other end. I've done 30' 6"x10" without any help before, using this system. The forestyforum link guy is probably safer.

Close to each end of the wall, attach a rope to the floor inside, run them up and over the wall, then under the log, back up and over the wall. Then you should be able to have people on the inside pull on the ropes and roll the log up the wall.

If they are too heavy for that you can run a couple of beams from the top of the wall angling out a ways to roll the logs up using the same trick.

Example with wall logs:

Thanks! Copied this, and we'll see if we can work it.

I installed our 40' post frame trusses by myself using scafolding and a cheap Harbor Freight winch. Trusses weighed 300-400 lbs each.

I lashed a 4x4 accross the top of the 5 levels of scafolding, and attatched a pulley to the 4x4. The winch was chained to the bucket of the tractor, which also supplied the 12v to power the winch. For lighter poles/logs, you might not need as much counterweight.
