[Beowulf] removing tiles around heavy racks?

The floor rating may be relevant.  Typical 'concor' floors made by Tate 
Access Flooring have point load ratings of 1250, 1500, or 2000 pounds.

Since this is a safety issue, I suggest you contact the floor manufacturer 
and ask their engineers directly.  I wouldn't trust any response that you 
get from this newsgroup as definitive.

Cheers,
