Seeking wisdom from those who have installed a lift

Buddy almost died under his lift at his personal shop. Anchor pulled the 4" concrete up when his girl's truck was on it. Ended up having to repour the slab with rebar.

Test drill first and make 100% sure you have adequate depth with every anchor. 4'-6" depth without rebar is okay as long as you're not lifting a tank. Keep an eye out for stress cracks and retorque the anchor bolts every once in a while.
