1. What is the Forklift Load Calculation Formula?

The Forklift Load Calculation Formula determines the actual capacity of a forklift based on the rated capacity, specified load center, and actual load center. It's essential for safe forklift operation and preventing tip-overs.

2. How Does the Calculator Work?

The calculator uses the forklift load capacity formula:

\[ Capacity = Rated\ Capacity \times \left(\frac{Load\ Center}{Actual\ Center}\right) \]

Where:

\( Rated\ Capacity \) — Manufacturer's specified capacity (lb)
\( Load\ Center \) — Distance from the fork face to the load's center of gravity (inches)
\( Actual\ Center \) — Actual distance from the fork face to the load's center of gravity (inches)

Explanation: As the actual load center increases beyond the rated load center, the forklift's capacity decreases proportionally.

3. Importance of Load Calculation

Details: Proper load calculation prevents forklift tip-overs, which are a leading cause of forklift accidents. It ensures safe operation within the forklift's stability triangle.

4. Using the Calculator

Tips: Enter the rated capacity from the forklift's data plate, the specified load center, and measure the actual load center. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What happens if the actual center is greater than the load center?
A: The forklift's capacity decreases proportionally. Operating beyond this reduced capacity can cause tip-overs.

Q2: Where can I find the rated capacity and load center?
A: These values are specified on the forklift's data plate, typically located near the operator's compartment.

Q3: What's the stability triangle?
A: The area formed by the two front wheels and the pivot point of the rear axle. The combined center of gravity must stay within this triangle.

Q4: Does attachment affect capacity?
A: Yes, attachments change the load center and capacity. Always consult the manufacturer's specifications when using attachments.

Q5: What about uneven loads?
A: Uneven loads create additional stability challenges. The actual center should be measured at the heaviest point of the load.
