Four post ramp in garage with no power

[Fessia fancier]

I should shortly have a garage completed with decent headroom so I can stack two cars. Unfortunately it doesn't have electricity and it looks difficult to get power to it (more accurately, I have had very high quotes).
I wondered if anyone had experience of a four poster which is manually powered. I found this one

but wondered if there were other options.
Alternatively has anyone experience of using a generator to power a four post lift?
It won't be in regular use, probably only every couple of months and I don't think I will need to use it for working on the car, it is really for storage.
Thanks

Thanks for the replies. Running a lead won't work as it is a couple of miles away from home :-). I'm interested in the generator solution. It would run very rarely and is a way from neighbours so the noise should not be a problem. Any thoughts on how big it would need to be and whether I'd need to route the exhaust gases out?
If a generator works, this is the kind of ramp I have in mind.

Thanks for the input. It sounds like a generator is the thing to explore. I did think the Jack per corner idea looked a bit laborious although I suppose it would work.
I will try to find out the peak load for possible ramps for some generator options. Fortunately I have a little time before the garage is complete.

Thank you. In case it is of interest the lift has a 3 horse power / 2.2KW motor which has an initial draw of about 20 – 25 amps, I am told.

Thanks for the replies. As for the size of the estate, I have a couple of hatches but no estate :-). The garage is in the next village.
I like the idea of an inverter/battery. I will try to scratch my head and see if i can figure out what would have enough power. A bit more building to go first, before we get to potential ramp stage, but any more thoughts are greatly appreciated.

[Fessia fancier]

Thank you. I will look into it especially as that gives options on lighting etc too.

Thanks. I may enquire about a 12v motor. It would be for occasional use so it wouldn't be a terrible inconvenience to have to take a battery home to charge it each time.

[Fessia fancier]

By way of a very belated follow up, the garage is more or less 90% built now. I can't readily get a 12v powered ramp so was looking at the inverters.

Does anyone have any thoughts on these, or indeed any alternative ideas?

I am happy to lug a battery or top it up with a solar panel. I'm curious to know whether the above will have enough oomph to get the ramp going with a car on it.

Thanks

Thanks I have definitely binned the idea of the manual jack ramp

Just power the inverter from your car. I'm guessing you will drive to the garage. You will easily find 2000 or 3000W inverters that you just hook up to your car's battery and then run the engine for these few minutes when lifting/lowering the lift

That seems neat though I will have to power it from the car while it is on the lift in that case
I guess I can use some long cables provided there are not too much in the way of losses?

Thanks for all the feedback.
The thing with a generator is that if it sits outside then it would be visible and perhaps a theft risk (the garage is not at my house). If I put it outside and cover it I could get problems because it is in a conservation area.. I also worry about it not starting, if it starts, runs for a minute and then stops, certainly with a car that would not be a good usage pattern. I could put it inside the garage and route the gases outside I suppose. I won’t be working on cars there.

Many thanks for the input!

Thanks. The the lift as it comes from the supplier has a 3 horse power / 2.2KW motor which has an initial draw of about 20 – 25 amps.

In terms of usage I doubt it will be used more than once a month. I can put a small solar panel somewhere discreet, I can't plaster the roof with lots as it is a conservation area and there are trees above. But if it gets a little light I suppose it can trickle charge.

Just to add the car won't be more than 1500kg. The ramp i have at home is a single phase one that works without tripping the electrics.

Some interesting ideas, thanks everyone for the input to date!

[Fessia fancier]

Well I have now completed the garage and decided to try the ramp powering solutions at home
I had the battery below already which was almost new and bought the inverter below which might not be man enough as the ramp was cutting out even when I lowered it.
I am a bit dim at electric stuff so would appreciate any feedback
Thanks

Thanks for both replies.

I was attracted to the inverter as I had a new Bosch battery which I bought for my car about six months ago and didn't use so I think it should also be in a good state. But at present it seems to be unable to run the lift just coming down from a fully raised position let alone laden and I have not yet asked it to raise a car...

So I might have to get a generator but I suppose having got this far it may be a beefier inverter would suffice.

To save scrolling, the lift has a 3 horse power / 2.2KW motor which has an initial draw of about 20 – 25 amps, I am told.

Of course, I could always sell the thousands of acres and get a house with better garaging!

[Fessia fancier]

Thanks I will check those things as soon as I can. The cables are the ones supplied with the inverter, perhaps 50cm long.

Find out whether the voltage is dipping under load at the inverter and at the battery. It's really your only way to know whether you have an electrical supply problem and if so where it originates.

Have you tried powering the lift directly from the mains to confirm it all works as expected?

Just to address this question, the lift works fine on the mains.

Evening and sorry for the slightly tardy reply due to the lurgy.....
When I put the inverter on the battery it shows 12.8 volts. It will, if connected carefully, lower the ramp but the ramp "stutters" on being raised and won't pull itself up, even without the weight of a car on it.
From the picture of the inverter I posted above, i read that as it taking a peak of 4000W with a running 2000W but I might be talking nonsense!
Is the suggestion that I need a 4500W inverter with presumably a peak of much more than that?

Thanks for all the comments.
