Hi Robert
Great score!
My math may be rusty, but.....
Remember, two people giving each other a hug, can comfortably put 200Kg
into a small area..... I keep this in mind when I see the sign at work
that indicates that the maximum floor loading is 400Kg/m2.... Two
people put 200Kg across their foot area, (about 0.12m2) = Which I
suspect works out as about 1666kg/m2!
Using the same maths, a lady wearing stilettos can easily drop 50Kg over
1cm2 - that is 500,000Kg/m2 - That probably explains the 'poc' marks on
wooden floors I see!
A normal timber floor will comfortably hold a couple of hundred kg
spread over the area of a 19" rack, keep in mind that your rack has
feet, so just place some 19mm board under the feet to distribute the load.

I don't know what it can bare, BUT, I'd be
inclined to recommend distributing the load. Get some long boards, and put under it with
the boards running the opposite direction of the beams under the floor.

I recently bought a lovely PDP11/45 in a H960
rack, with the CPU, a Unibus
Expansion box and an RK05 drive. I am guessing the whole thing must weigh at
least 100Kg, possibly 150Kg or even more (my worst case estimate is 200Kg).
I am concerned whether the floor of the upstairs room where I now have it
can bear the weight. I have placed it right next to a load bearing wall to
ease the strain on the joists. Can anyone tell me what sort of weight a
normal UK upstairs floor can bear? If my guessed weight is anything close to
the limit I will weigh parts of the machine to get a more accurate idea of
the actual weight.
Thanks
Rob
