Installed a Direct Lift 4-post lift in my shop the other day

I would be worried about it tipping over ,say your letting it down and you didn’t notice a safety lock was hung up and all the weight shifts ?? At least if she’s bolted down you got a chance .
All these new fangled lifts have a secondary lock, and if it goes wonky it basically jams up.
Have had a couple buddies that thought they knew how to operate hoist and got it stuck on one latch. You notice right away.
I wasnt pleased to say the least.
