Raising grainstore roof

Feel free to offer one !

If you just need the height to tip trailers, rather than store more, is swapping to ejector trailers an option?

See #28

Indeed, it’s being considered!

In one of the early practical farm ideas, there was a feature on someone who did this, jacking the whole roof up in one piece with hydraulic rams, with a tractor on each ram to supply the oil, maybe @farmideas would have the feature on file ?

Could be a winter project. Pair of rams lifted off every silage trailer in the parish and .... elevate.

I know it sounds daft, but it has been done.

Wondering if anyone has ever raised an existing roof on a portal frame building...eg: remove all roof cladding...dismantle/take down steel rafters, purlins etc...weld extra 4ft onto stanchions...then refit rafters and re-clad roof. Would then need extra or replacement vertical cladding. Could this be cost effective? Getting fed up with restriction in tipping grain trailers!!

ejector/moving floor trailer no steel/welding /drilling/broken sheets /bad language/divorce ect

I can remember the story, but think the roof was taken off and each portal lifted and the 4ft section inserted one by one. They may also have drilled holes so the joins were held steady with some angleiron. The man doing the work fell through the asbestos and suffered multiple injuries, but this was obviously nothing to do with the mechanics of the job. He could so easily have put more boards up so he was on them all the time.

Assuming the legs are strong enough in the first place to take the extra height I reckon Id be trying what was said earlier on.
Remove the sheet above the column and weld on a extension with the top bored ready for taking the rafter and eaves beam.
Every extension piece would have angle or flat guide plates too to help when raising. Weld/clamp/bolt a foot for the jack under each rafter.
Then get a heap of high lift bottle jacks, enough for each column, wont need to be that big really, can sell them later if you want.
Unbolt all problematic stuff, side cladding, wiring etc.
Then jack it up one side at a time, 3 inches maybe then other side the same, time about till your out of lift, then stick a spacer in and repeat.
Trouble with telehandlers/forklifts and long rams connected to tractors is control, the outside corners will want to go first as they have less weight, and synchronizing them all is difficult.
Given a bit of planning Id do it.

Be certain it can't all crash down. I built some timber cow kennels made the frames from 7 x 3in factory floor boards and had them all propped up with struts and a few ropes ready for cladding. While I was standing in the middle the inevitable happened and they collapsed like dominoes. Still can't work out how I was left standing. That surely was one of my lives gone.

Howard harvestore erected their towers using 'screw' jacks all connected together with pto shafts. Electric motor through gearbox driven iirc. Lifted slow and equally although jacks were designed to turn tower round slightly while lifting. Jacks were bolted to sheets.

Have an engineer check out the base plate / HD bolts / foundation design of the existing to see if there is sufficient redundant capacity prior to carrying out significant raise in height. Raising the roof will be the easy part of the bottom bits fail....
