What should a plant verify before a critical crane lift during an outage?
Critical lift readiness requires more than a crane booking. The lift plan must match actual load, rigging, ground conditions, work interfaces and authorized execution controls.
Confirm the lift scope and engineered plan
Identify load weight and center of gravity, lift points, rigging arrangement, crane configuration, radius, boom length, capacity chart and any applicable engineered approvals. Follow the site definition of a critical lift and jurisdictional requirements.
Verify site and equipment conditions
Inspect access, ground bearing support, underground utilities, obstructions, overhead electrical hazards, weather limits, barricades and exclusion zones. Confirm crane inspection, operator qualification, rigger and signal person competency, and lift gear condition.
Coordinate the outage interfaces
Confirm equipment isolation, scaffold and insulation removal, adjacent work permits, traffic routes, spotters, communications, contingency position and weather hold criteria. Assign a single lift director or other role according to the site procedure.
Industrial example
An air cooled heat exchanger bundle replacement requires a crane operating beside live plant equipment. The team verifies load calculations, underground services and barricades, then holds a prelift briefing with operations, riggers and the mechanical contractor before release.
Close the readiness gate
Perform a documented prelift walkdown. If configuration, weight, ground conditions or personnel differ from the approved plan, stop and reassess. Preserve the approved plan and deviations with the outage work package.
Implementation checklist
- Approve load and crane configuration
- Verify ground, utilities and electrical clearances
- Confirm competent personnel and permits
- Complete prelift briefing and stop criteria
