Which part of the load charts does not show boom deflection?

• A. Range diagram
• B. Load radius chart
• C. Elevation chart
• D. Angle diagram

Answer: (A)

Range diagrams focus on safe lifting capacities across different reach configurations. They map how much you can lift at various radii and boom lengths, and their purpose is to show the operating envelope in terms of load and geometry, not how the boom physically bends under load. Boom deflection is a structural response that would require a separate deflection analysis or chart, not this diagram. The other parts of the load charts convey lift geometry—how far out the load sits (load radius), how high it can be lifted at a given radius (elevation), and the boom’s angle—without detailing boom bending.
