I'd not hesitate to hire safe movers for a large safe, but for a safe the size of a refrigerator, weighing 4-600 lbs, seriously consider an appliance dolly guys. I move mine around solo, and only need one helper if stairs are involved. Strap it to the dolly, tilt it over , and then it's just a balancing act and easy IMO. Might be one of the best hundred dollars I ever spent 20 years ago....safes, fridges, and my 180 lb speakers are easily done solo.
The appliance has rubber like treads on the back for sliding up/down steps too...can you tell that mine ain't for sale
?
