Forklift Load Center and Capacity Calculations
Forklift Load Center
1. Measure the length of the load you’re lifting.
2. Divide that number by 2.
Resulting number is your load center.
Ex. If lifting a pallet that’s 48 inches long, load center would be 24 inches from face of forks.
Forklift Lifting Capacity
Rated load center ÷ Actual load center x Rated capacity of Lift
Revised Capacity
(Truck capacity x Load center) / (New load center)
New Capacity
Base capacity x (Base LC ÷ New load center)

X = Load Center
Y = Effective Thickness
Rated Load Center: This is the forklift’s rated horizontal load center, as specified on the forklift’s data card.
New Load Center: The new horizontal load center, calculated by adding the effective thickness of any attachments to the original load center. It represents the distance from the mast to the center of the new load.
Rated Capacity: The forklift’s lifting capacity at a given height, noted on the data card. Adjust this by subtracting any additional attachment weight not included in the original capacity rating.
Example:
Rated Load Center: 32 in.
New Load Center: 45 in.
Rated Capacity: 3000 lbs.
DeRated Capacity: 2133 lbs.
Forklift Load Center
The load center is the distance between the vertical part of the forks (the face) and the center of gravity of the load being carried.
In most forklifts, this distance is typically rated at 24 inches.
Center of Gravity
The center of gravity refers to an imaginary point within an object where all of its weight is concentrated. This concept is crucial for maintaining balance and stability, especially when lifting heavy loads with a forklift.
Understanding these concepts is essential for safe and efficient forklift operation, ensuring that the load is balanced and the equipment is used within its rated capacity.
Load Capacity
Load capacity refers to the maximum weight a forklift can safely lift and carry. This capacity is closely tied to the load center, the distance from the load’s center of gravity to the front face of the forks. It’s important to ensure that loads are centered when lifting to maximum height or carrying at maximum capacity to maintain stability and safety. The load capacity can vary based on several factors, including the use of attachments, the height to which the load is lifted, and the overall balance of the forklift.
Net Capacity
Net capacity, also known as payload capacity, takes into account additional elements that may impact the forklift’s lifting capabilities. This includes attachments, the style of the mast, and any other add-ons. The net capacity represents the actual weight a forklift can safely handle when these factors are considered. Understanding net capacity is crucial for ensuring that the forklift operates within its safe limits, preventing accidents and equipment damage.
Importance of Load Center
When operating a forklift, maintaining load stability is crucial for safe and efficient handling. A key factor in this is understanding the load center.
The Role of the Counterweight
In a loaded forklift, the counterweight plays a vital role in balancing the load on the forks. The counterweight must effectively offset the load to prevent tipping.
The Importance of Centering the Load – If the load is not properly centered, it can destabilize the forklift. This imbalance increases the risk of tipping, which can lead to serious injury or even death.
Forklift Weight Considerations – Did you know that forklifts typically weigh about three times their rated lift capacity? This significant weight helps ensure stability, but only when the load is correctly centered and balanced.
By understanding these principles, you can keep both your forklift and its load stable, ensuring a safer working environment.
