Who here has used them? I am trying to find out (what's the formula) for how many you need for how large an area? (Model T 1920's Garage)
Thanks

House jacks

HF I think sells them, looks sorta like a jack stand, except usually cast with a big threaded center section you rotate to raise it up. As I recall the jacks are real strong, could be 10 or 20 ton if I remember correctly, so its not the jack capacity that decides how many you need, but the strength of the structure you are lifting and how many lift points how far apart are required.

Its not so much about the jacks you need its about the cribbing you need. We poured a foundation under our house using 2 house jacks and a rail jack which works fine as long as you have enough cribbing to support your loads
House movers use air jacks around 20 ton. They cut a hole in the crawl space on both ends use a front end loader and a chain and pull the beam about 80 foot long under the house.
For a ranch house they would use two and some cross beams. They jack up slowly on each end. Then they put the wheels under the beams and chain down. On the front they have a beam with a ball for the fifth wheel this is chained down also. The front end loader picks up the beam blocking is placed under the beam for the jack.

you can just use 20 ton bottle jacks and blocking.
