if it is a big safe (> 1k lbs) and you are going down steps, i'd advise getting a moving company to do it. if you put 1k safe on even the heaviest fridge dolly and try to take it down steps, somebodies going to get crushed. i move mine with a 3k pallet jack from work but its all on one level. if you have a walkin basement, get a few sheets of plywood and a pallet jack and some 2" black iron pipe to get you over the door thresholds. then lay the plywood on the grass and roll the safe on the jack over it and leapfrog the plywood as you go. thats the way we got mine into my house. it weighs 1100 lbs and it wasn't easy.
