Which device provides critical information about the safe reach of a crane during a man basket lift?

• A. Load chart
• B. Rigging tag reader
• C. Boom length indicator
• D. Rope tension gauge

Answer: (C)

Understanding safe reach starts with knowing exactly how long the crane’s boom is. The boom length indicator shows the current length of the boom in use, which directly determines how far the hook or man basket can reach. This length data is essential because the crane’s rated capacity and safe operating limits depend on the boom length being used. Once you know the boom length, you can reference the load chart to confirm that the given reach is within the crane’s capacity for that configuration. Rigging tag reader and rope tension gauge serve other safety checks (rigging ratings and rope tension, respectively) and do not provide reach information. The load chart is crucial for understanding what loads are safe at a given reach and configuration, but by itself it does not display the actual reach—the boom length indicator provides that direct information needed to assess safe reach during a man basket lift.
