Which crane feature is required to lift a man basket?

• A. Counterweight alignment
• B. Boom length indicator
• C. Rotating beacon
• D. Quick release pins

Answer: (B)

Knowing how crane capacity changes with configuration is essential when lifting a man basket. The weight of the basket plus the people inside must stay within the crane’s rated capacity for the current reach. A boom length indicator provides the exact length of the deployed boom, so the operator can look up the correct load chart and verify that the lift is within safe limits for that reach. Without knowing the boom length, you can’t confirm the lift is safe, which is why this feature is required for lifting a man basket. Other features serve safety or setup roles but don’t by themselves confirm safe lifting capacity for a man basket: for example, counterweight alignment relates to stability, a rotating beacon is about visibility, and quick release pins secure attachments but don’t determine whether the lift is within rated capacity.
