Will my floor take the weight?

Page 2 of 2  


No guarantees on this answer but this is what I would do.
That's a pretty heavy cabinet, but if you and 3 buddies stand together in your living room, the floor doesn't collapse. But wood can settle over time. In my living room there is a noticeable depression where the stone fireplace lintel (maybe 400 lbs) was set on the floor while the house was being built.
So, I'd make some wood blocks, maybe 2" x 2" or 3" by 3" and put them under each leveling leg to spread the load. Put the cabinet against the wall so the feet are between the joists. Then, in the crawlspace, build two columns out of concrete blocks and wood shims (put them in tight) under the floor where the two front legs are located. You can get wide hardwood shims from a mobile home supply company.
Good luck. Steve.

Hi,
[ insert standard disclaimer here ]
Your floor should be fine:
Structural strength : If you think about it in another way, would you be concerned if 4 large(ish) people were to stand close together on the area of floor that you intend to put the cabinet?
Surface strength : Prefinished hardwood floors are usually finished with an epoxy which will easily take the pressure you describe, the underlying hardwood itself should also have no problems as they typically have no problems supporting high heel shoes. High heels often have areas of less than 1/4 square inch, assuming only half a persons weight is on each heel, pressures in excess of 300lbs per square inch only requires 150lb person.
I hope this helps.
Reg's, Thomas D.

The floor joists of the crawl space are what dimension and what spacing? When placing a load against a wall where floor joists below bear on structural support such as a load bearing basement wall the floor and joists themselves may support the weight when using 2x10 floor joists 16" OC but to be especially secure you canand probably should consider bracing by using a 4x4 double T brace ( TT ) underside of the floor joists to carry the extra loads down to the slab or soil below. You see the way the T illustrates a brace and two columns? If there is soil under the crawl space stack a couple of leveled concrete patio blocks onto the surface of the soil to function as a pad the columns bear on. Use 4x4 for the brace and columns. It wouldn't hurt to ask a building inspector for advice either.
