What is a load center and how does it affect forklift capacity?

• A. The load center is the vertical height of the load above the forks; higher centers increase capacity.
• B. The load center is the horizontal distance from the fork face to the load's center of gravity; larger centers reduce rated capacity and increase tipping risk.
• C. Load center is the distance between forks; larger distance increases carry capacity.
• D. Load center refers to the weight distribution in the truck; it doesn't affect forklift capacity.

Answer: (B)

The load center is the horizontal distance from the face of the forks to the load’s center of gravity. Forklifts are certified to lift a certain weight at a specific load center (often 24 inches). When the load’s center of gravity sits farther from the forks, the tipping moment increases, so the safe lifting capacity decreases and the risk of tipping goes up. In practice, you must use the capacity rating that matches the actual load center; if the load center is larger than the standard, you can’t lift as much as the nameplate might imply. This is why the other ideas don’t fit: the vertical height of the load above the forks isn’t the determining factor for capacity, even though tall, top-heavy loads can affect stability. The distance between the forks isn’t the load center—the critical measure is where the load’s weight acts relative to the forks. And load center isn’t about the truck’s own weight distribution; it’s about how the load’s weight is distributed in relation to the forks and how that influences tipping risk.
