It must have taken 3-4 guys to set those blocks on the jacks like that.... If you have to use blocks to support anything they should never be used with the webs horizontal. put them on flat ground preferably with a board on top. And basically they are doing the dame thing they were designed to do in building a foundation. But as soon as you jack up part of the vehicle, there are sideways stresses at work on the blocks, so still far from ideal. I have used them that way to block up a car, but still throw stands in to get under it. That 2nd block above the green jack is really thin web. I wouldn't block my push mower up with that thing. :BangHead:
