Which option lists the items found on a lifting/spreader beam?

• A. WLL; Angle factors; Reeve factors
• B. Serial No.; Manufacturer's ID; Country of origin
• C. WLL; Serial No.; Material type
• D. WLL; Serial No.; Manufacturer's ID

Answer: (D)

The main idea is understanding what markings on a lifting/spreader beam convey its safety and traceability information. A lifting beam is a load-handling device, so the three critical pieces shown on it are the Working Load Limit (WLL), a serial number, and the manufacturer's ID. WLL tells you the maximum safe load the beam is rated to lift. The serial number provides a unique identifier for that specific unit, which is essential for tracking inspection history, service records, and any recalls or certifications. The manufacturer’s ID identifies who made the beam, which is important for verifying authenticity, obtaining proper documentation, and contacting the maker for parts or re-certification. Among the options, the set that includes WLL, the serial number, and the manufacturer’s identification covers all the essential information needed for safe operation and proper traceability. Other options either omit the WLL, add items like country of origin or material type that aren’t as critical for immediate safety and inspection, or mix in factors (like angle or reeve factors) that relate to rope and rigging calculations rather than the tag information on the beam itself.
