🔍 Key Concepts

• Crane boom geometry and how operators know its position • Difference between capacity charts and physical position indicators • What information is needed to calculate a crane’s safe load radius

💭 Think About

• Ask yourself: which option describes a measurable position of the boom that can be shown on a simple gauge or dial? • Consider how the crane’s reach (load radius) changes when the boom moves—what specific change must be monitored? • Which of the choices would normally be found in a separate load chart or specification sheet, not on a real-time indicator?

✅ Before You Answer

• Verify which of the choices represents a real-time physical position of the boom rather than a fixed specification. • Consider which information is required so the operator can use a load chart to determine safe lifting capacity. • Eliminate any options that are usually marked on data plates or charts, not on moving indicators.
