Should I be concerned about bringing a ~600lb safe into a 60yr old house with a very large/empty crawl space directly below it...

I can't risk damaging the floor bringing it in or risk having the safe damage the floor where it will be residing permanently in a closet...

Looks like the ~600lb is on the far light end of the safe spectrum, with some of the more hardcore safe's pushing 1-2k lbs...

Am I being overly cautious?

So, 150 lbs a corner, on wheels? Use ply wood to go across the hardwood for sure, we have used Carpet and cardboard, but not really cool. So 150 lbs a corner, how many square inches a corner is this load distributed on?

Looking @ this safe

Safe alone is 400lbs, figure at max I will be placing 200lbs worth of ammo & items inside.

Dimensions: 59” H x 28”W x 20”D

I've never worked construction so I have no idea if I am being overly cautious but I was just envisioning the safe falling through the hardwood floor into the crawl space lol...

Is it on wheels? Or laying flat on the floor? If its flat, the load is 154lbs a sq ft or 1.07 pounds a square inch. Based on 28x20 footprint. 560 sq inches or 3.88888 sq feet. S can your floor take 4 154 lbs girls standing next to each other without breaking? A piece of paper is smaller than a sq ft, ie 8.5 x 11. That is close to the same as 2 foots together. Picture 4 people with feet together as the load.

With that said. This is a good read

Interesting read...

Looks like this safe would be sitting flat on the hardwood floor in closet.

I'm #300 standing on less square area than that. For a small fee I'll come stand where your going to place the safe and test the floor for you.:43:

if YOUR hardwood is like MY hardwood (home built in 1949), it's stronger. First, the wood is better. Second, there is no plywood subfloor in my house. There's a subfloor of straight 2x4's. On top of that is a second subfloor of 2x4's. On top of that, the hardwood.

Drilling holes for electrical wiring is a bastard and a half. and drilling for the 4" dryer vent was terrible. But the floor is bombproof.
