That looks like a setup a garage here in town has.He says it is a jack,not a lift.He calls it the tire and brake lift.It has little wheels in the back,and they move it around the garage as needed.While it doesn't look very stable to me,he showed me that when you set it up as close to the car as possible,it is a lot more stable than it looks.The most he or his help get under it is to retrieve a dropped part or tool.Bolted down I bet it would be fine.It has a half dozen holes in it to slide pins into once it is at desired height.Then he drops it to rest on the pins while in use.
