Which items are examples of Below-The-Hook Lifting Devices?

• A. Hooks and Chains only
• B. Pulleys and Snatch Blocks
• C. Crane Rails
• D. Lift Beams, Spreader Beams, Fabricated Lifting Devices

Answer: (D)

The main idea is about attachments that stay below the crane hook to connect to the load and shape how that load is lifted. Lift beams, spreader beams, and fabricated lifting devices are designed specifically for this role: they attach to the hook and provide the proper point or points of contact, distribute weight, and tailor the lifting configuration to the load’s geometry. A lift beam gives multiple attach points along a single beam; a spreader beam spreads the load across a wider area to prevent overloading a single point or deforming the load; fabricated lifting devices are custom-made attachments that fit the load and lifting requirements. Hooks and chains are basic rigging hardware that participate in lifting but are not specialized below-the-hook devices designed to modify how the load is held and distributed. Pulleys and snatch blocks are used to redirect force or gain mechanical advantage in the rigging system, which is part of the lifting setup but not the specific below-the-hook device category described here. Crane rails are part of the crane’s structure, not lifting attachments. So, the items that truly exemplify below-the-hook lifting devices are lift beams, spreader beams, and fabricated lifting devices.
