1. What is Forklift Load Capacity?

The forklift load capacity is the maximum weight a forklift can safely lift at a specified load center. It's affected by the truck's design, attachments, and load characteristics.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{Truck Capacity} \) — Manufacturer's rated capacity (lb)
• \( \text{Attachment Derate} \) — Capacity reduction due to attachments (lb)
• \( \text{Load Adjustment} \) — Any adjustments for load characteristics (lb)

Explanation: The equation accounts for the base capacity of the forklift minus any reduction from attachments, plus any adjustments for special load conditions.

3. Importance of Load Capacity Calculation

Details: Accurate load capacity calculation is crucial for safe forklift operation, preventing tip-overs, and maintaining equipment integrity.

4. Using the Calculator

Tips: Enter the truck's rated capacity and attachment derate values from the data plate. Use load adjustment for special conditions like off-center loads.

5. Frequently Asked Questions (FAQ)

Q1: Where do I find the truck capacity?
A: The rated capacity is listed on the forklift's data plate, usually located near the operator's compartment.

Q2: What is attachment derate?
A: The reduction in capacity caused by attachments (like clamps or rotators) that shift the load center forward.

Q3: When would I use load adjustment?
A: For non-standard loads where the center of gravity differs from the rated load center (24" for most forklifts).

Q4: Does this account for lift height?
A: No, this is a basic calculation. Actual capacity decreases as lift height increases due to stability factors.

Q5: Is this calculation sufficient for all situations?
A: For complex situations, consult the forklift's load capacity chart or a qualified engineer.
