How do I move this rock?

Actually, something like this perhaps?

I unfortunately do not have a very well placed tree.

Search for "lifting gantry hire". Outrageously expensive though.

Farm jack under the bar to lift the rock, build up a platform as it's being raised and then slide onto the bed.

Exactly how I’d do it, farm jack on A frames, lift it, slide planks under it and keep repeating to get it above the wall.

Alternative is build a scaffold frame with a block and tackle on it.

I don't really understand the A Frame bit, any images to help, please?

£60/day from HSS, doesn't sound too bad for something that will avoid a very bad back

All of the above - too much like hard work.

Like the Egyptians - you build a ramp - possibly ballast + sand

Then your four builders will haul it up the ramp with ropes and into position.

I can't find any sequential images but anyone who can think like an Egyptian and walk like an Egyptian will know what I mean.

The lower base for the ramp possibly the whole ramp could be topsoil to enhance your garden after the epic move.

Totally doable - give it a go and lets see the photos.

My best post ever -

Possibly couple of parallel scaffold boards on the ramp as a sliding base.

It's just something to stop the jack leaning forward, you use a couple of lengths of wood, have a look at this video around the 3min40sec mark to get the idea

Not sure how high the wall is but this is a 60" jack, usually they are 48"
They were knocking them out at £56 delivered last week

Obviously you can still get additional height by putting the jack on a platform as well if needed

Ideally I would want to enslave the tribes of Judah to help assuming becoming a pharaoh is not on the cards.

Parbuckle it up a slope

My guess is that it is a water feature. The hole through which the steel rod passes is probably the route for the water. I helped a neighbour move a similar, but narrower water feature rock. We estimated it at 250kg. (Density of granite is 2.65 to 2.75g/cm^3)
I made a platform with nine 100mm castors and used an engine crane to lift the rock off the delivery pallet onto the trolley. This allowed the rock to be rolled though the house and across the patio to the bottom of a similar wall. The house owner then arranged for nine of the builders who renovated the house to lift it by hand over the wall and into position. I wasn't there for that stage so can't give more detail.
The stacked pallet approach sounds like it might work, however you need to think what happens if one of the pallet breaks or slips. Bear in mind that the shape of the rock means the load will not be evenly distributed on the top pallet, so an inch or more of plywood will be needed to prevent the pallet slats breaking. Having been present at work when someone suffered permanent disabilities as a result of a rushed lift, I wouldn't risk it myself.

HSS two tonne gantry hire appears to be £60.05/day, and is money well spent given the risks to people and property if the stone drops. Whether they will rent it to a private individual without lifting and slinging credentials remains to be seen.
A layer of corrugated cardboard a few inches thick would give the floor surface some protection if the rock rotates as it is being lifted.

One last thing, don't rely on one sling!

They will. I've hired all sorts of dangerous gear from them, and scaffolds, without any request for tickets.

Trolley/Dolly. Loads of ramps.

[FMOB]

Probably something like a skid steer or something bigger to lift that failing that have a lower rockery.

Also note to self: employ better project manager.

If you were a proper PHer, you’d be a regular gym goer and this wouldn’t present a problem. Bulk up on protein shake and put your back into it.

Or get a mini digger. Why does it have a metal rod through the middle of it, can King Arthur and his men help?

Ramp, loads of trolley dollies

Exactly how I've moved a large slab in the past too. On my own too. Jacked up one side, slid supports underneath, jacked up other side. Admittedly not as high as OP needs to go. Need to be careful not to have it land on his toes or worse (/obvious)

Edit not "exactly" as I wasn't sure what a farm jack is, and now I've googled it, I didn't use a farm jack but a normal car jack stuck beneath it. Inch by inch and build up as you go

Genie lift is a good shout although one big enough to lift that will probably be just as heavy as the rock to manoeuvre.

You need an expansion grout for chemical expansion and cracking.
I've used this in construction projects to break the head of concrete piles in order to tie the steel reinforcement to other structures.

What could possibly go wrong.
