What about jacks, jack stands Engine stands and hoists? Anybody know how that will hold up to that kind of abuse or is it beyond its design?
There have been several threads about this issue if you want to search, but to give you the basics:
Standard jackstands with "angle iron" legs will literally cut through RD when loaded. I found that out the hard way, but RD replaced the damaged tiles (plus several more square feet) and they were easily replaced. I also found that my too small floor jack leaves ruts in the tiles when loaded. I have gotten around this by using a 1/8" 12x12 aluminum plate under each jack stand and another 10x24 plate under the jack. Kind of cumbersome, but it works. I've done it this way because I have three sets of jack stands already. If I had it to do over, I would buy myself a few sets of these:
I probably still will, but I'm just trying to justify it at this point. My tool boxes (both quite large) don't mar the RD so I don't think a hoist or engine stand would either. The weight has to be concentrated on a very small area to damage it.
Hope this helps.
