The cars people use that lift on weigh the same as the car the dealer/service station services on the lift in their shop. Look at how those lifts are installed, the lift base, the type anchors used and the specifications of the concrete...... Drop in anchors that grab the top couple of inches of concrete? No way id use them
If you use a lift once a week or all day every day, that lift has to be securely mounted in concrete that has the strength and depth required according to specifications
I used Redhead drop in anchors to mount my tubing bender to the floor. They are threaded and there is no stud, you run a bolt into them. I was able to remove the tubing bender from the center of my garage when not in use and not have it in the way. I probably installed/removed it 30-40 times over the years and I never had an issue with an anchor coming loose.
Im familiar with drop in anchors and have used them in certain applications. Installation of a car lift, I would never use them
