How do I move this rock?

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

I would guess the stone is nearer 1000kg, given the fact it cannot be moved by four blokes used to moving heavy stuff as a living.https://www.hss.com/hire/p/beam-trolley-for-alum-g...
Given that, I think the gantry system suggested is the only suitable suggestion.
Not sure when the hell I'll get the chance to do it as I'm out and about a fair bit, but that's the plan!
Sack barrow!
Only wish I had taken my own advice, I attempted to lift a large rock like that on my driveway recently, which I had previously put there using my own sack barrow, I decided I didn't need it this time and tried to lift the rock in to a wheel barrow and put my back out instantly!
I moved said rock about inch and have now been suffering with back pain for 5 weeks

Any estimate on weight?
Looks like it could be granite and therefore very heavy, maybe 500/600kg?
I don't think I'd trust an engine hoist with that amount of weight.
If 4 blokes are getting it off the ground it will be nearer half that unless they're all powerlifters.Looks like it could be granite and therefore very heavy, maybe 500/600kg?

Shear legs would work if you can find a suitably heavy car to put outside the gate as an anchor point. Unless you already have the necessary long poles, blocks and tackle its unlikely to be cheaper than hiring the HSS gantry crane though.
This is what I'd do, but it depends on whether the OP has scaffold tube or lengths of wood, rope etc. to construct a shearlegs with.Given the varying estimates of weight from 250kg to 1000kg, it looks like knowing the actual weight of it is the first part of the problem to solve. OP, put it in a vessel of water and use Archimede’s principle to calculate its volume. The.n use the average density of granite to calculate its weight. At least you then know what you’re dealing with.

And a smart person would place that vessel on the higher level prior to lifting the rock into it so that after conducting the displacement measurement the rock would be in the right place and the vessel dismantled around it. Eureka!PhilboSE said:

My way of estimating the weight of things like that is that a litre of water weighs 1 kg so 1 cubic metre of water weighs 1000kg. Then imagine whether it is more or less an a cubic metre.Sorry, but I think you are all confusing this matter for the op. Every time I see a problem like this the first thing I think of is fire, and then "what would the Romans have done"
Hannibal dominated the alps thus "According to Livy, and repeated in Ammianus Marcellinus (de Sanctis, 1917:77 ff), the ancient engineers poured boiling vinegar on the rocks to facilitate their massive cracking along with burning the rocks by a fire underneath them"
op, you needs some Sarsons and some oxyacetylene.
As to how it got there

Do you need to move it because you want to keep it or just because you want rid of it? If the latter then break it up. One way would he have a very long and hot fire under it/around it and then dump bus keys if ice and cold water on it. Slow process but that’s the way they used to do it before heavy equipment and explosives were used…

We have the answer.Hannibal dominated the alps
Hire a couple of elephants, they will move that easily.
