Best way is to know a buddy who works with beverage machines--they'll have access to a truck with a hydraulic "tommy" lift on the back, this is very handy. They also will likely have some ramps and the like for getting a coke machine sized and weighted object up steps and the like.
Worst way is to have a frieght company do drop off at your curb. Your safe will be all snug there in the back of the box or trailer--spotted there by forklift on pickup. Customer is responsible for getting 8-900# 30-36" down to the ground. This can make for a "comedy of errors" best observed from across the street.
If you are collecting from a retail store, or maybe a shipping dock, the loading is not bad. But, you really want a funriture dolly (and one rated to the weight) to have control of things. Took three of us to wrestle my Liberty up three concrete steps on a dolly, and that was one step at a time. Once it was in, on the wood floors, furniture glides and focused effort was all it took to spot it after that.
If you have to go up, to then go down into a basement--well, your mileage may vary (hiring some movers for just the hour, to have a "stair-walking" appliance dolly would be well worth the $150 it might cost).
