What happens to a forklift's rated capacity when a specialized attachment (e.g., a side-shifter or clamp) is installed?

Question: What happens to a forklift's rated capacity when a specialized attachment (e.g., a side-shifter or clamp) is installed?

Answer options:

• The forklift's capacity remains exactly the same.
• The forklift can now lift more weight because of the extra steel.
• The operator can calculate the new capacity by doubling the old one. ✅ The forklift's rated capacity is reduced and must be reflected on a new data plate.

Correct answer: The forklift's rated capacity is reduced and must be reflected on a new data plate.

Explanation: When an attachment (like a paper roll clamp) is added, it changes the weight distribution and moves the load center forward, effectively reducing the net capacity. Only the manufacturer or a professional engineer can authorize the new capacity rating.
