When should a hoist cable be replaced?

• A. When it is rusted
• B. When it is kinked, crushed, or bird caged
• C. When it shows signs of wear
• D. When it is too long

Answer: (B)

A hoist cable should be replaced when it is kinked, crushed, or bird caged because these conditions indicate that the structural integrity of the cable has been compromised. Kinks or crushes can lead to uneven load distribution and increased stress on certain areas of the cable, making it prone to failure. A "birdcage" effect occurs when the wires of the cable start to separate or distort, leading to weak points that can snap under tension. Ensuring that the hoist cable is in optimal condition is crucial for the safety and efficiency of crane operations. Functionality and safety must always be prioritized, and any visible signs of these issues require immediate attention to prevent potential accidents.
