BBURN:
I occasionally help out at a local gun store that sells a lot of safes.
They normally get $100 to $150 to deliver, depending on the distance and difficulty.
A friend recently got a Liberty Washington 40. Big mutha, about 1200 lbs.
He asked me to help move it. Easy, since he was going to put it in his garage and leave it on the pallet, for now. The store had a forklift, pallet jack, and climbing dolly they use.
They told me to take the tailgate off the truck, to prevent damage. The dealer put the safe in my truck on its back, still in the cardboard, with the pallet hanging off the back. I put the pallet jack in to help, though the guys said I could get by with 3 or 4 3' lengths of 3" PVC pipe to roll it across the floor.
Got to the house, pushed the safe toward the rear of the truck till it hit the balance point, and then he and I lowered it carefully to the ground before tipping it upright on the pallet.
Put the pallet jack under it and rolled it into place easy as pie, before taking the jack back to the store. Put the tailgate back on.
Lessons learned:
The safe can be easily moved by two people, assuming you either have the right (expensive) equipment, and do not need to take it up stairs. Without the equipment (using PVC pipe), it would have probably have taken at least four people to get it into the garage. Without a serious heavy dolly, preferably a climber, I believe that it would be difficult, if not impossible to get it in the house and up stairs given any number of people without damage to the movers, house, or safe.
Bottom line: If you do not have access to the equipment, I would hire a pro. $100 is probably less than rental of the equipment, beer and food for your friends, and repairs of damages to property.
