So it has been a while since I have built anything worthy of posting, but I just completed a hoist for the ventilated shop space and it might be of interest for some here. The first picture is my initial drawing, based on the materials I had available. It changed as heavier material became available.
My trolley and chain hoist are both 1 ton but the I beam and mounting can except up to a 3 ton trolley and hoist, if the need arises. It was a quick project that generated lots of pictures. You can see the full build here Hobby Workshop Projects: workshop hoist.
