Load center matters
A truck’s rated capacity assumes a stated load center (often 500 mm / 24 in). Longer or uneven loads increase moment and reduce safe capacity:
Allowable ≈ Rated × (Rated LC ÷ Actual LC)

Frequently asked questions
Attachments?
Sideshifters, clamps, and jibs reduce capacity further — use the attachment data plate.
Lift height?
Many charts derate at height — this tool is load-center only.
Is this the data plate?
No. Always follow the truck capacity plate and site rules.
Uneven loads?
Use the farthest significant mass as the actual load center.
