Lift Planning and Evaluation

Lift Planning and Evaluation

Before using any rigging device it is important to “plan your work and work your plan”. The “front end” time required to develop a successful lift plan may seem unnecessary for small or “non-consequential” loads. There’s always enough time to pre-plan “critical” lifts. After an incident involving what seemed to be a “non-consequential” amount of weight, the time required to mitigate the mess will dwarf the time spent on what was thought to be an unnecessary lift planning session. There’s always enough time to do the job right, the second time. We encourage you to make the “front end” investment in lift planning and successful rigging, before each and every lift.
A trained, qualified and knowledgeable user must take into account the following factors and issues and consider all relevant factors not addressed. Among the factors related specifically to slings and rigging, users must perform several activities, including (but not limited to) the following items:

Environmental Considerations


Load Considerations

  • Wind
  • Weather
  • Visibility
  • Object Temperature
  • Environmental Temperature
  • Chemical Conditions and Exposure
  • Stability of the Ground
  • Underground Installations
  • Weight

  • Dimensions

  • Center of Gravity

  • Attachment Point Integrity

  • Structural Stability: Bend and Flex

  • Susceptibility to Crushing or Compression

  • Secure or Remove Loose Parts

  • Combination Loads-Drain Fluids

  • Damaging Surfaces and/or Edges

Equipment and Lift Criteria


Rigging Considerations

  • Single or Multiple Crane/Hoists
  • Maximum and Planned Operating Radius
  • Allowable Load (From Load Chart)
  • Ratio of Lift to Allowable Load
  • Clearance between Boom and Lift
  • Clearance to Surrounding Facilities
  • Power Lines and other Hazards
  • Clear Path for Load Movement
  • Emergency/Contingency Set Down Area
  • Thorough Equipment Inspection
  • Sling selection: Type and Capacity
  • Load Control
  • Lift Point over the CG
  • Appropriate Hitch for CG and Load Control
  • Coordination of Multiple Slings
  • Positive Sling to Load Engagement
  • Coefficient of Friction: Sling to Load
  • Load is Free to Move and is not Snagged
  • Sling Capacity is Adequate (Angle and Tension)
  • Adequate Sling Protection

Personnel Considerations

  • Area Clear of Unnecessary Personnel

  • Personnel are Trained and Qualified

  • Tag Lines and Spotter Requirements

  • Signals: Visual, Audible, Electronic

  • Pre-Lift Plan and Meeting

  • Personnel Away from Danger
