What is the purpose of keeping the forklift's center of gravity within the stability triangle during operation?

• A. To reduce the risk of tipping.
• B. To increase speed.
• C. To improve fuel efficiency.
• D. To reduce operator fatigue.

Answer: (A)

The essential idea is balance: a forklift’s stability depends on its center of gravity staying inside the stability triangle formed by the wheels. This triangle defines the safe area for the combined weight of the forklift and any load. When the center of gravity stays inside that triangle, the lifting and moving forces create a restoring moment that keeps the machine upright, even during turns, starts, stops, or when lifting a load.

If the load or movements shift the center of gravity outside this triangle, the forklift loses its balance and tipping becomes much more likely. That’s why keeping the center of gravity within the stability triangle is about preventing tipping, not about speeding up, improving fuel efficiency, or reducing fatigue.
