Which statement about preparing for a complex lift is most accurate?

• A. The lift plan can be informal and can skip load CG details if the operator is experienced.
• B. Only the rigger needs to know the plan; others need not.
• C. For a complex lift, ensure the rigging plan includes load weight, CG, attachment points, rigging methods, and lifting sequence.
• D. For a complex lift, avoid documenting the lifting sequence if it’s difficult.

Answer: (C)

A thorough, well-documented rigging plan is essential for a complex lift. This plan should clearly specify load weight, the load’s center of gravity, attachment points on the load, the chosen rigging methods, and the lifting sequence. Knowing the load weight ensures you select appropriate slings, hardware, and capacity limits to prevent overloading. The center of gravity tells you how the load will balance and how sling angles and leg lengths will affect stability, reducing the risk of unexpected movement or tipping. Specifying attachment points ensures the load is secured at safe, structurally suitable locations rather than improvised spots that could slip or fail. Detailing rigging methods—such as how many legs, what hardware, and what configurations—guides the team on exactly how to configure the rigging to achieve controlled lift and redundancy. Finally, outlining the lifting sequence provides a step-by-step plan and communication needs so everyone acts in a coordinated way, which is critical for preventing miscommunication during complex operations. Skipping CG details, treating the plan informally, relying on only one person’s knowledge, or avoiding documenting the sequence all undermine safety by removing essential situational awareness, teamwork, and a clear reference for actions.
