In lifting, a 90,000 lb load with a 100,000 lb rated crane is considered a

• A. Simple Lift
• B. Complex Lift
• C. Critical Lift
• D. Routine Lift

Answer: (B)

Lift complexity is about the level of planning and risk required, not just whether the load fits on the crane. Here the load is 90,000 lb and the crane is rated at 100,000 lb, so the capacity margin is small. That tight margin means dynamic factors like wind, sway, rigging stretch, and sudden movements could push the load toward the crane’s limit, demanding more careful calculations, a documented lift plan, and closer oversight. These extra planning and coordination needs characterize a Complex Lift. It isn’t a simple, routine lift with standard procedures, but it isn’t automatically a critical lift with engineered permits unless other hazards are present.
