Critical Lift Plan Documentation

Engineered critical lift plan inspection for non-routine crane and rigging lifts, capturing load weight, crane configuration, lift radii, ground bearing conditions, and signal protocols before execution.

Lift Plan Authorization

• Lift plan completed and approved before mobilization
  Documented lift plan is present, current, and approved by the responsible competent person or designated authority before crane setup begins.
• Lift classified as critical or non-routine
  Lift meets site criteria for a critical lift, engineered lift, tandem lift, personnel-adjacent lift, or other non-routine operation requiring enhanced controls.
• Pre-lift briefing completed with crew
  Lift briefing reviewed the sequence, roles, hazards, exclusion zone, stop-work authority, and emergency actions with all involved personnel.
• Competent person and signal person identified
  A competent person and qualified signal person are assigned and understood by the crew.
• Required permits, engineering review, and site approvals present
  Any required permits, engineered calculations, customer approvals, and site authorization documents are available at the jobsite.

Load and Rigging Verification

• Verified load weight recorded
  Actual or calculated load weight is documented, including all rigging, hooks, spreaders, and attachments to be lifted.
• Load center of gravity identified
  Center of gravity is identified and accounted for in the lift plan and rigging arrangement.
• Rigging gear selected for load and configuration
  Slings, shackles, hooks, spreaders, and other rigging hardware are rated for the load and compatible with the lift geometry.
• Rigging inspection completed
  All rigging components were inspected before use and show no visible damage, deformation, excessive wear, or missing identification.
• Attachment points verified
  Load attachment points, lifting lugs, and connection hardware are verified as suitable for the planned lift path and forces.

Crane Configuration and Capacity

• Crane make, model, and configuration documented
  Crane type, make/model, boom length, counterweight, jib, and outrigger configuration are recorded in the lift plan.
• Planned load radius verified
  Planned working radius is measured and matches the crane chart configuration used for capacity calculations.
• Crane capacity adequate at planned radius
  Planned load, including rigging and dynamic factors, remains within the crane's rated capacity for the selected configuration and radius.
• Load percentage of rated capacity documented
  Calculated load percentage at the planned radius is documented and reviewed for critical lift criteria.
• Anti-two-block, load moment, and safety devices functional
  Required crane safety devices are present and functional for the planned operation.

Ground Bearing and Site Conditions

• Ground bearing capacity verified
  Ground or support surface capacity has been reviewed and is adequate for crane loading, outrigger reactions, and lift path conditions.
• Outrigger mats or cribbing installed as planned
  Mats, pads, or cribbing are installed per the lift plan and sized for the expected load distribution.
• Setup area level within plan tolerance
  Crane setup area is level within the tolerance specified by the manufacturer or lift plan.
• Overhead and side obstructions cleared
  Power lines, structures, plant equipment, and other obstructions are identified and controlled for the planned boom path and load path.
• Weather conditions within lift limits
  Wind, visibility, precipitation, and lightning conditions are within the limits established by the lift plan and manufacturer guidance.

Communication, Exclusion Zone, and Final Sign-Off

• Primary signal protocol established
  Primary communication method is defined, including hand signals, radio channel, or designated signal person authority.
• Exclusion zone established and controlled
  Barricades, spotters, or other controls prevent unauthorized personnel from entering the lift area.
• Tag lines and load control methods available
  Tag lines or other approved load control methods are available where needed to control rotation and swing.
• Stop-work authority communicated
  Crew understands that any worker may stop the lift if conditions change or a hazard is identified.
• Final authorization to proceed
  Responsible supervisor or competent person authorizes the lift after all critical items are verified.
