Well done indeed. This is why small machines fetch such a premium.
This is a valuable lesson I have learned today.
I will be enlisting the help of Steve for the transport but once at my workshop, I will be using an engine crane to move it into my workshop and into position, I will need to basically replicate what you did with your mill. Thank you for sharing the pictures of your moving techniques. It has given me some more confidence that what I am doing is viable.
I will also rely on the advice of Steve as he clearly sounds like he knows what he is doing. We will probably make a plan before anything is even moved based on what needs to be done at the destination.
It can be daunting the first time you do it, but if you think through everything that could possibly go wrong and figure out how to eliminate each potential issue, it will go smoothly when you do it.
If you have a lingering doubt about something, don't start until you've figured out why and either gone through it enough to be sure it's not an issue, or found an alternative approach.
If you're planning to hoist it up a tiny bit and wheel it on the crane, then sweep, sweep, and sweep again.
With that kind of weight on them even little bits of grit can cause the castors to bind up awkwardly, if you have a rough floor finish, consider getting a couple of sheets of hardboard or ply to run on.
Also be aware of any slight slopes, even a slight uphill that's not immediately obvious will be appreciably harder to push nearly a tonne of cast iron up, and anything obviously sloping underfoot could pose a risk of rolling back.
If you're dealing with a slope that has a risk of roll-bacl, then Toolstation sell an inexpensive 2T ratcheting come-along, which can be anchored to the ground with a piece of angle iron and two concrete screws, I have a photos somewhere of me pulling my lathe Harrison mill up a 15°-20° incline on rollers and skates with one.
Needless to say, pull on a central point as low down as possible (and on the crane not the machine) for stability.
Edit: Photos.
It was not ideal or comfortable to have that much extra height under it, but given the available options was far more secure that way as compared to using a thinner less stiff ramp would have been
In any case the come-along allowed me to be well outside of the danger zone whenever the machine was being moved and assess its stability before approaching to add rollers or position the skates for the transition off the ramp.
The positive of wheeling it with an engine crane is that as long as the centre of mass is inside the legs, it will be much more stable than trying to push/pull it on skates/rollers.
Do be aware that when moving a hoisted load like that, if it does tip forward, whilst the machine stands a much better chance of not falling over, the crane could be kicked out backwards and upwards.
You can minimise the risk of that by lifting the load as little as possible to minimise the potential energy involved, and not standing directly behind the crane when you move it if you do have to lift it higher for some reason.
