A gun safe's weight is the greatest obstacle to its portability, which is the way it is supposed to be. Because a gun safe is so heavy, moving it requires the help of a few people, and the stronger they are, the easier moving the safe will be.

Empty the safe of its contents.
Lift one side of the safe and slip the appliance dolly under the edge of the safe with assistance from helpers. Wrap the load strap around the safe and cinch it down so the safe is securely fastened to the appliance dolly.
Tip the safe back onto the dolly. At least three people are needed to hold the top of the safe up while it is in transit. Wheel the safe in the direction of the new location if it is on the same floor. Slowly tip the safe back up when it is in place so it sits flat on the floor. Position at least two people in front of the safe to help ease it back down while at least one person places his foot behind the dolly's wheels to keep it from rolling backward.
Remove the strap from around the safe when the dolly is upright and pull the dolly out from under the safe. Put the dolly aside. Replace the contents of the safe.
