What is the load center of a forklift, and how does it affect the rated capacity on the nameplate?

• A. It is the vertical distance from the face of the forks to the load's center of gravity used in the nameplate rating.
• B. The load center is the horizontal distance from the face of the forks to the load's center of gravity used in the nameplate rating; capacity decreases as the load center increases beyond the rated center.
• C. It is the distance the forklift can lift without tipping.
• D. It is the width of the load.

Answer: (B)

The load center is the horizontal distance from the face of the forks to the load’s center of gravity. This distance matters because the nameplate rating is calculated for a specific load center. When the load’s center of gravity sits farther from the forks, the tipping moment around the forklift increases, so the allowable weight must be reduced to keep the machine stable. That’s why the rated capacity on the nameplate is given for a standard load center, and the chart will show lower capacities as the load center moves farther away. If the load center is closer than the rated distance, you’re effectively within a tighter lever arm, but you still rely on the nameplate and capacity chart to know the safe limit for that exact center. The other options describe vertical distance, how high the fork can lift, or the width of the load, none of which define the load center or its impact on capacity.
