When the priority is achieving a greater lifting height, which bag type is typically chosen?

• A. Low-pressure bags
• B. High-pressure bags
• C. Medium-pressure bags
• D. Non-pneumatic bags

Answer: (A)

To get more height from lifting bags, the key is how much the bag can expand as you inflate it. Low-pressure bags are designed to expand the most, using a larger air volume at a lower internal pressure. That greater expansion translates directly into a taller lift before reaching the bag’s safe pressure limit. High-pressure bags stay more compact and stop expanding sooner, giving you quicker lifts but less vertical travel. Non-pneumatic bags don’t inflate at all, so they can’t contribute to lifting height. Medium-pressure bags sit in between. So when the goal is greater lifting height, low-pressure bags are the best choice.
