And when you think it's strong enough, double the heightI'll make a replacement which I'll ensure is strengthened appropriately,

Nah, if I need to work on something higher, I'll borrow the use of the 20-ton one at my local garage. This one is plenty tall enough for anything I'll need.

Aye, that'd be the limiting factor.....

Is it a set date every year or when a certain temperature is reached ?

This time of year again...
Brother is doing his today also! He’s further south than you I think.

That thing when you start using a new Chinese tool and end up rebuilding it in the first hour as it self destructs.
Pivot shaft should have had a circlip. Replaced with an M8 bolt for now.
M3 tool lasted one rivnut.
Found a stainless M3 bolt the right size.
Drilled out old thread on lathe.
Silver soldered new bolt in
Finally get to do the job I wanted to do!

not technically fixed but tested, dismantled, loaded, drove 100 miles, then unloaded a 4 post lift, 3.5T capacity with centre cross lift. Have a lot of expensive car / van bills coming up, and I've been humming and haaaaaing for a good while now whether I could justify one or not, but when I was getting quotes just for the van repairs at 1200 euros for work I can do myself with a lift... sod it, decided the time was right to go for one. Found this one for 750 euros, not too far away. Had a decent day out with a mate, my van and flatbed trailer...
now just got to pour a new foundation, 4.5m3 of concrete, and rebuild it in place, pull in a new cable / air line to it and recommission it.... will be far easier building it here than taking it apart, at least I can get in with the front loader forks on the tractor, so will be able to lift the ramps directly into place, the rest are manhandlable so not too difficult.....
Reckon it should pay for itself pretty quickly, as a fair bit of work coming up, this will be so much easier on the knees and back... already had the mates asking when will it be finished so they can borrow it.......... as soon as you come round and give me a hand with the concrete... hahah..
Hopefully next weekend will be able to dig the foundations out, and shutter it, then the following weekend be able to pour.. then wait til it hardens fully (28 days they recommend?).. hopefully, end of Nov should be operational... maybe, hopefully etc...
I'm sure my knees and back will thank me....

Oh I did not know there was a thread for stuff you have fixed, well my last post would fit better here then. But it's already posted so I will just link it:

Stuff you have made today
I came into my local men's shed the other day to see two of the guys drilling into the end of a 3" cylinder of wood about 9" in length with a fairly big Forstner bit. One was operating the pillar drill, the other holding on tightly to keep the cylinder level (kids, don't try this at home!). OK...

I've been led to believe it's more like 3 months for concrete to be fully cured.
that's what I thought too, but the manufacturer recommends a minimum of 3000psi rated concrete, and 28 days. Asked a mate who's a builder, he reckoned a month would be fine as well? not my speciality, any experts on concrete on here ?
When my work had groundwork done for ramps, everybody involved was happy for ramps to be fully loaded after 7 days.
Although that was with fibre reinforced concrete, and probably lots of accelerant.
Aye I reckon 28 days will be fine, will probably end up being longer anyway, as I can only really escape to get to work on it at the weekends (saturdays), so even though it might have the lift on the concrete, probably wont have any weight (car / van) on it for a while after that.
the next question was what type of anchor bolts would be best, conventional sleeve type or chemical? I'm thinking 20mm should be enough, can't find anything from the manufacturer, but the bolt holes are 20mm ish, so we'll go with that I'd reckon..

I've always been told a week per inch up to 6" thick for concrete to cure.
The lift is roughly 5m x 3m so we're allowing about 1 metre each side, 1 metre in front, and then 2.5 / 3m behind for the ramps depending on final placement (might be able to share some with an existing slab 
). For the footings of the 4 columns we're planning doing 500 by 500 x 300mm deep. All reinforced with rebar, and that will be tying into the roughly 100mm thick slab, an all in one pour...Obviously we'll order the truck based on the final dimensions, but fag packet calcs come out somewhere between 4.5 and 5m3. The majority will be around 100mm thick, so a week per inch would be about the 4 weeks, albeit the footings for the columns would be thicker... think it should be right?

4 posters are pretty much self supporting so anchoring the feet isnt as critical as a 2 post lift so a couple of weeks would be fine for drying time, if your putting rebar in remember your going to want to drill the pad for fixingsThe lift is roughly 5m x 3m so we're allowing about 1 metre each side, 1 metre in front, and then 2.5 / 3m behind for the ramps depending on final placement (might be able to share some with an existing slab
aye, agreed, should be fairly stable, the guy we bought it from has only used a couple (instead of 4) of what looked like 10mm anchors in each corner so don't think it'll be a big problem but I'll go a wee bit heavier I think. We've inherited the owners manual, which nicely has a bolt hole layout drawing, so that'll be used for keeping the rebar areas clear for decent anchors.....
Will probably go with the sleeve type, as the concrete will be new, so should get a decent fixing.

2 weeks is standard around here for anything critical. Yes - critical - because the sheer overspec of anything critical makes sure it's absolutely fine
I put my uncle's old 2.5 ton 2 poster in my old shed on old concrete... 4-5" deep... worried about it for the first week and then forgot all about it
