What is the purpose of a rated capacity indicator on some cranes?

• A. To indicate the weather and wind data.
• B. To display the crane’s current safe load limit for the configured setup, aiding overload prevention.
• C. To provide maintenance history.
• D. To show the color of the load chain.

Answer: (B)

The rated capacity indicator shows the maximum safe load for the crane given the current setup, including boom length, angle, radius, and any attachments. It uses sensors and the crane’s control system to calculate this limit and displays it to the operator, helping prevent overload by keeping lifts within the safe capacity. If the load would exceed that limit, the system can warn or restrict hoisting. It does not provide weather or wind data, maintenance history, or information about the color of the load chain.
