Which standard addresses below-the-hook lifting devices in crane equipment?

• A. ASME B30.20
• B. ASME B30.19
• C. ASME B30.79
• D. ASME B30.10

Answer: (A)

Below-the-hook lifting devices have their own set of safety rules because they present unique hazards when attached below the crane hook, such as how they connect, wear and fatigue, rated capacity, and inspection needs separate from the crane’s moving parts. The standard that covers these devices is ASME B30.20, “Below-the-Hook Lifting Devices,” which lays out the design, construction, installation, inspection, testing, maintenance, and safe operation requirements for such devices. This focus helps ensure that spreader bars, clamps, slings, and other hook-attached equipment are treated as specialized safety items rather than generic crane components. The other standards listed address different crane-related topics or components and do not specifically govern below-the-hook devices.
