What is the maximum number of high-pressure air bags that should be stacked?

• A. Two
• B. Four
• C. Three
• D. Five

Answer: (C)

Stacking high-pressure air bags changes how the lift behaves because each bag adds height and weight, raising the center of gravity and shifting load distribution. To keep the lift safe and controllable, there is a safety limit on how many bags can be stacked. Staying within this limit maintains a stable base and predictable lifting behavior, reducing the risk of the stack tipping, shifting, or bag failure during inflation or lifting. Exceeding the limit makes the setup top-heavy and unstable, increasing danger to personnel and anyone nearby. So the correct choice reflects the safety-recommended maximum number of bags to stack, in line with manufacturer guidance and training.
