Is a rigger required for Assembly/Disassembly operations?

• A. True
• B. False
• C. Not specified
• D. Depends on the weight

Answer: (A)

Rigging assembly and disassembly are high-risk steps in any lifting operation, so they require a trained rigger. A rigger brings the knowledge to inspect all rigging gear for wear or damage, choose the right hardware for the load and configuration, and perform the setup or takedown in a safe, proper sequence. This includes ensuring pins and cotter pins are correctly installed, verifying that all components are within rated capacities, and confirming that the load path, sling angles, and connections will not overload any part of the rigging. The rigger also coordinates with the crane operator and crew to control movement and prevent unexpected shifts, drops, or pinching hazards. Because improper assembly or disassembly can lead to gear failure or a dropped load, having a rigger is required regardless of the weight involved.
