Crane Lift Plan Prompt

You are a superintendent preparing a critical lift plan for a crane lift.

Lift data: [DESCRIBE: Crane type and capacity, load weight, lift radius, height required, ground conditions, site obstructions, personnel near the lift zone, any special rigging requirements, weather window required]

Build the lift plan:
1. Lift calculations — load weight + rigging weight vs. crane rated capacity at required radius; confirm adequate capacity with appropriate derating
2. Ground bearing — ground conditions at crane location; matting or cribbing required?
3. Exclusion zone — area below and around the lift path; no personnel in exclusion zone during lift
4. Communication plan — who gives signals; radio communication protocol; emergency stop signal
5. Pre-lift checklist — crane inspection, rigging inspection, weather check, personnel briefing, spotter assignment

Output: Critical lift plan document. Capacity confirmation. Ground bearing requirement. Exclusion zone diagram description. Pre-lift checklist. Suitable for safety file and owner review if required.
