How does the load center size relate to the lifting capacity of a forklift?

• A. Directly proportional
• B. Inversely proportional
• C. Unrelated
• D. Constant

Answer: (B)

The load center size is a critical factor that directly influences the lifting capacity of a forklift. The correct understanding is that the lifting capacity is inversely proportional to the load center size. This means that as the load center distance increases, the forklift's capacity to lift that load decreases. To elaborate, the load center is defined as the distance from the vertical face of the forks to the load's center of gravity. When a load is placed further away from the truck's vertical support (i.e., the load center increases), the forklift has to counterbalance a greater moment created by the load. This additional moment can lead to stability issues and a higher risk of tipping over. Consequently, because of these safety concerns, manufacturers specify a lower lifting capacity for loads with larger load centers. This relationship emphasizes the importance of understanding load center measurements when operating a forklift, as exceeding the specified capacity can lead to unsafe conditions, including the potential for accidents or equipment damage. A solid knowledge of this principle helps operators maintain safety and efficiency in their lifting tasks.
