I don't have time for movies. I just went out and bought 1 of " EZRA's " electric hoists from Harbor Freight. I'm starring at the cieling of my man cave trying to figure out how mount it without pulling the " bonus room " down on top of me. Then I have to plug it in somewhere ??? If I plug in 1 more item ..... I'm going to shut down the grid !

I used I think 1 3/4 steel about 10ft long so it would span 5 joists and if I needed to pull something verry heavy like a boat motor I could pull under and wedge some 4x4 under each side still have not had to pick up anything that heavy but the option is there
That is exactly how I mounted mine. Used lag bolts and caught 5 joists. Small world. Thank you harbor frt.

I have a simpler set-up. I primarily lift in the same area, by the HO lights & tool boxes in the center of the 2 bay. I used 3/8th's X 5" lags with fender washers to secure the P treated boards to the rafters then bolted the flanges w/ 1/4-20's & nylocks. I C-bored the back of the boards and used fender washers on those too. Kind of hung it on black pipe so it can move back n forth about 2' and swivel a little as needed. Here is a pic,

i don't think it's a good idea to hang on a pipe fitting
The shear strenght of those threads has to be in the thousands of pounds . Do you know other-wise ? I was just guessing from my strenght of material class years ago. I thought about using a solid piece of 0-1 or S-7 for the cross shaft and cutting the threads on it. I just don't get carried away lifting too much. Just the ends of sleds or jet-ski's. The hoist only has a 880# limit. I would appreciate if you have other info. I estimated the thread shear strength to exceed the hoist limit ???? Please say so if there is something I didn't factor in. You have me worried.

Mike, you way over engineered it compared to what I have done. My Harbor Springs hoist is the 1200# model and I used a 7' pc. of 1 3/4" galvanized well pipe and hooked it to the ceiling with 4 pipe clamps and 8 lag bolts. Hooking into 2 joists on each side and leaving 32" in the middle to slide along. only use to lift back of sled up. staying up just fine. I like your idea. My garage attic has 2' of blown in insulation to crawl in so I did it all from below. If I were pulling engines out of a car I would most definately improve upon my set up. I'm not so sure about the strength of the flanges you used, I think they are cast steel and may lose strength during galv.

got any pics of your set up?

I agree the flanges are the weak link, but i got so excited when I seen those that I had to have them. I could have machined plates to bolt the pipe to w/ U bolts but I was already in work Saturday milling up some support plates for the skid of another sled. I will keep an eye out for the threads stretching or flanges loosening up and maybe improvise. I had an entire 3 seater jet ski hanging from less that that before. Of course I'm polish.... and near catastrophy is always a possibility. That's why I'm a lifelong member of " The School Of Hard Knocks " .... Suma Cum Laude .... I may add.
Thanks for the input guys.
