I assume your talkin' hydraulic when you say in ground Scott. You sure have enough height for a nice lift in the shop and your floor would support a 747. My concerns are with the way they are mounted to the floor. Like I said, I've never heard of any one having a problem with one pulling out of the floor. I must be missing something, I probably need to go out and look at a few to get a better handle on how they are installed.
