I am afraid to take my crane to Wisconsin,because I would have to drive with it through truck scales. But I am wondering, can some chain hoists under your rafters help you?
My pole barn is a stick build, rafters are 2x8's. Doing this type of work would need a 10 ton gantry.
I believe 294 to 94 from you.....absolutely legal. The road to get to me in WI would be 50 at Kenosha....and I believe you're legal the whole way. I have an M817 I took down 12 through Richmond, hit the scale there...no issue (my truck is good to 45k loaded). A crane on a low boy, not sure going via route 12.
Happy Thanksgiving.
