On the project house, there are 3 piers made with concrete blocks sitting on concrete pads (3 block high). Then they had a jackpost splitting each span. While I like the ease with which the Tapco jackposts install and the weight they can handle, I’m always looking at them and thinking that if anything happens and the load is lifted briefly, those posts are going to fall down.
Are there any alternatives to jackposts that are just as quick to install and easy to adjust?
I’ve toyed with the idea of converting the jackpost supports to the same 3-block arrangement. Also considered some short lally’s that could be affixed to the pad/beam.

If you're only taking the load off, and not doing any significant lifting, weld a short section of pipe to the top and bottom plates. If memory serves, I think I used 1" pipe for the top, and 3" for the bottom. Only an inch or so long. These will serve as a retainer for the jackpost. But you have to secure the plates at the top and bottom or the pipe cups can shift. It does make placing the top plate more of a PITA, but it works. Also, the steel rods they give you with the posts have a tendency to fall out, so either duct tape them in or use bolts with nuts, or some other method of retaining them in place.
