Forklift - Stability and Capacity ExamQuestions and Answers
The Stability Challenge - Answers -The Stability Challenge
In order to prevent your forklift from tipping over, you must keep the forklift's combined
center of gravity inside an area known as the forklift's stability triangle.
Capacity of the forklift
Weight of the load
Size, shape, position, and center of gravity of the load
Direction and speed of travel of the forklift
Grade of the surface on which you're operating the forklift
The Stability Triangle: Lever Is Like a Seesaw - Answers -Imagine a lever like a
seesaw. It is a bar with weight on each end and a balancing point in the middle. The
balancing point is called the fulcrum
Stability Triangle: Forklift Is Like a Seesaw - Answers -A forklift is like a seesaw too.
There is a load on the forks in the front of the forklift and a counterweight in the back.
The balancing point, or fulcrum, is the center of the forklift's front drive axle or front
wheels. Putting a heavy load on the forklift will cause the forklift to tilt forward.
Stability Triangle - Answers -While a forklift can tip forward and backward like a seesaw,
it can also tip from side to side. A forklift's stability triangle is an area bordered by the
forklift's two front wheels and the pivot point, or middle, of the rear axle. In order for the
forklift to stay upright, the forklift's combined center of gravity must remain within the
forklift's stability triangle.
Load's Center of Gravity - Answers -Ideally, the load's center of gravity will be at the
center of the forks. However, the load's center of gravity may not be in the center of the
forks if the load is oddly shaped, not evenly distributed, or not sitting as far back as
possible on the forks.
Combined Center of Gravity - Answers -After a forklift picks up a load, the mass of the
forklift and the load are combined, resulting in a single, relocated center of gravity.

Forklift's Center of Gravity - Answers -An unloaded forklift's center of gravity is generally
located under the operator. However, it may be located further back on an extra large
forklift with an elongated counterweight.
