The stability triangle is used to describe the movement of center of gravity of a load vehicle like trucks If the load is not balanced then it moves and may tip over it If you were to raise a lift truck up and look at its underside, you would see that the support points for the truck are located at points A, B, and C The triangle formed between points A, B, and C is called the Stability Triangle The lift truck will not tip over as long as the center of gravity remains inside the triangle The center of gravity is the point within a lift truck where there is equal weight all around it
