Forklift max capacity is the maximum weight the forklift can safely lift. It is not a single number—capacity changes based on load center, lift height, mast tilt, and attachments.
Where to Find Your Forklift's Max Capacity
The capacity is stamped on the forklift's data plate (nameplate) . OSHA requires this plate to be:
Durable and corrosion-resistant
Clearly visible to the operator
Includes model/serial number and weight information
Never operate a forklift with a missing or illegible data plate .
The Three Factors That Reduce Actual Capacity
Factor Effect
Load center Further from fork face = less capacity
Lift height Higher lift = less capacity
Mast tilt Tilting forward reduces capacity
Real-World Capacity Examples
Forklift Model Rated Capacity Load Center Actual Safe Capacity
Hyster H3.5XT 3,500 kg 600 mm 2,350 kg (33% loss)
Crown SP 2350 3,500 lbs 24" 1,900 lbs at 48"
Toyota 8FGU25 5,000 lbs 24" 3,150 lbs at 36"
Yale GP190DF 19,000 lbs 24" Heavy-duty, full data plate required
The Formula for Capacity Reduction
Safe Capacity = (Rated Load Center × Rated Capacity) / Actual Load Center
Example: 5,000 lb at 24" load center handling a 36" load center
(24 × 5,000) / 36 = 3,333 lbs maximum safe load
Load Center Explained
Load center is the distance from the fork face to the load's balance point. Standard load centers:
400 mm (16") for small forklifts
500 mm (20") for mid-size
600 mm (24") for standard warehouse forklifts
1,200 mm (47") for high-capacity units
High-Capacity Forklift Examples
Model Max Capacity Power Type
Yale GP190-280DF 19,000 – 28,000 lbs LPG
Yale GDP80-120DF 8,000 – 12,000 kg (17,600-26,400 lbs) Diesel
EP EFL2503-HV 25,000 kg (55,000 lbs) Electric (Lithium)
Quick Safety Rules
Never exceed the capacity on the data plate
Capacity assumes mast vertical—tilting reduces it
Longer loads (larger load center) = lower safe capacity
Attachments add weight and shift load center—always check adjusted rating
