Forklift certification Certification Forklift certification Load Handling and Stability 2

Question 1

What is the 'stability triangle' on a counterbalanced forklift?

Accepted Answer

The area formed by the two front wheels and the center of the rear axle

Answer

The stability triangle connects the two front wheels and the pivot point of the rear axle, and the combined center of gravity must stay inside it.

Question 2

As you raise a load to full height, what happens to the truck's lateral stability?

Accepted Answer

It decreases because the center of gravity rises

Answer

Raising a load lifts the combined center of gravity, making the truck more likely to tip sideways.

Question 3

Why should a load be carried tilted slightly back and low to the ground?

Accepted Answer

To keep the center of gravity low and cradle the load

Answer

Tilting back and carrying low keeps the center of gravity low and secures the load against the backrest.

Question 4

What happens to the forklift's maximum capacity when the load center distance increases beyond the rated value?

Accepted Answer

The safe capacity decreases

Answer

A load center farther from the mast increases the tipping moment, so the truck can safely lift less weight.

Question 5

The standard load center used on most forklift data plates is measured at what distance?

Accepted Answer

24 inches

Answer

Most rated capacities assume a 24-inch load center, meaning the center of gravity is 24 inches from the face of the forks.
