Which item must be marked on all overhead cranes?

• A. Manufacturer name
• B. Maximum capacity
• C. Rated capacity
• D. Model of crane

Answer: (B)

On overhead cranes, the key safety figure is the rated capacity—the maximum load the crane is designed to lift safely under specified conditions. This rating is clearly shown on a rating plate attached to the crane, and it’s what the operator uses to prevent overloading. Exceeding this limit can overstress the crane structure, damage the rope or gears, and create a high-risk situation. While other information like the manufacturer name or model might appear on the plate for identification, the essential marking that must be present on every crane for safe operation is the rated capacity.
