Thanks, all! I knew I could count on you.
First off, Mekender wins the prize for most novel suggestion
I'll try to cover things briefly...
Gandalf - thanks for the photos/links - yes, I can hire all that stuff locally if need be. I can't see the freight pry bar / stevedore / roller pinch bar in the catalogue I have open right now, but no doubt they have such things too.
Aglifter - I don't have photos handy, but I'll try to post some later, provided it's not pouring rain when I get home. I like the idea of putting a hard surface on the pallet.
A friend is looking into getting some willing and muscular Poles for me. I'll see if they think they can do it door-to-door.
As an alternative, I'll negotiate with the German riggers about whether they would come to Brussels (a 6-7 hour drive) and do the necessary at this end too. Their quote for pickup and kerb dropoff was about 2400 euro (x 1.4 for US$), and I hope
the trip to Belgium wouldn't add too much to that. As Rumpshot said, I got the safe for a song, because the cost of moving it is substantial, but I always knew that would be the case. The way I look at it, the moving operation will probably cost
me around 3000 euro. I have paid more than that for a couple of the firearms which will eventually live in the safe, so if it prevents the theft of just one of those, it has paid for itself.
I intend to put the safe on the poured concrete floor of a garage designed for parking cars, so I think it should be solid enough to support the safe. I suppose a damp-proof course of some sort between floor and metal would be a good idea, though...
There are a couple of tricky points:
Tipping: the make and model of the safe isn't apparent (it must be pretty old, but it's fully functional) so I can't easily find out whether it can be tipped without harm to the locking mechanism. I'll have to take my chances on that.
The safe is too tall to go through the garage door upright, because the approach to the door is on a slope; even if the door were removed, the lintel is still too low.
There's not a lot of headroom in the garage. The safe can only be tipped upright somewhere near the door, as the rest of the ceiling is lower (lower than the longest diagonal of the safe). My plan would be to get it upright somehow (!), and roll it into
position on steel rods, pyramids-style, as HTRN and others have suggested.
Unfortunately, the low headroom will be a problem for using an engine hoist, and I don't know that a forklift could operate there, unless there are ones whose boom doesn't stick up very high.
Getting down the slope: this is the bit that worries me most - I believe the professional riggers would use a self-propelling dolly with caterpillar tracks. The DIY version would probably involve turning the safe on its side on the pallet, then sliding the pallet down the slope using a winch attached to the tow-hitch of a big truck. The slope is concrete paving slabs with a pebbled surface.
The German riggers say they would ship the safe standing upright on a pallet. If could get them to ship it lying on its back on a double-wide pallet, it would probably be easier to use a forklift to get it from the kerb into the garage, if the forklift could negotiate the downslope while carring the load. Again, getting it off the pallet and into a standing position would be difficult. Perhaps a forklift with a rotating-fork
attachment would do the trick?

I had vague thoughts of welding bolt-on attachment points for a D-shaped "pram-chassis" arrangement to the corners of the safe; construct the "pram" with axles for two pairs of wheels, and using bottle jacks to lift it onto the wheels. The "D"
would also allow tilting the safe while preventing it from falling over. I got the idea from a safe-moving dolly I saw in an industrial supply catalogue, which used two bottle jacks to lift the safe into a wheelable position once it had been slid
onto the carrying surface (photo).

This safe dolly would be ideal but for (a) getting the safe off the pallet and onto the dolly) and (b) the safe won't fit through the door standing-up...
Anyhow I'll get on the phone tomorrow and try to find a safe-mover in Brussels for a quote, at least.
