| Either way, I am posting this because I need more jack power. I have
| a 20 ton bottle jack, but those things lift so little at a time. I
| believe I can only lift 4 inches before I have to put more blocking
| under the jack for another 4". The tractor jack is not strong enough
| and neither am I to lift any higher with that jack. I do also have
| some of those old screw jacks, but those things are harder to use than
| bottle jacks, but will come in handy for temporary posts.
|
| Does anyone have any idea what other jacks are available for this sort
| of thing?
| I need POWER, and lots of it, because my tractor loader would not even
| lift it, and I can easily life a one ton round bale with it.
|
| The other question is how much does something like this actually
| weigh? It's all Oak framed, an covered with steel barn siding. The
| sill plate as well as the floor joists are 2x8 (actual size, rough cut
| timbers). There is also a bad section in the sill plate (about 8
| feet) where I will have to attach a large timber when I lift at that
| point. I should note that lifting this will be a slow process and I
| wont be lifting the whole building at one time. The barn will flex as
| I lift at different points, and I'll be doing most of the lifting from
| the outside until it is stabilized. Then I will work on the posts
| under the building, which appear strong but some of the support beams
| have dropped off the outer walls and are suspended in the air, only
| jammed under those posts.

Check with the local heavy truck wrecker company. Many have air bladders
that they place under a tipped load to ease it back into place with air
pressure. FWIW I've seen these things move a Mississippi river barge.
