Think of the weight on the base footprint.
What if one air line fails while going up or down?

Total footprint weight is no different than is being carried by 4 rubber, air-filled donuts. Pressure on floor (PSI) is probably lower with the QuickJacks as they have a fairly long steel frame, though I haven't measured mine to see how the total surface area compares to the footprint of the tires.
The hydraulic lines have much higher burst pressure than working pressure. My 7,000 lb lift is also barely working when I use it, as the heaviest vehicle I have is less than 4,500 lbs.
