ECI – Engineers Construction

Every lift should consider the following:

1. Designate a qualified person to perform the rigging.
2. Establish a communication protocol between the rigger and the crane operator.
3. Work with the crane operator to determine:
   1. Crane radii and boom lengths to achieve the pick
   2. Crane capacity at the maximum pick radius at required boom lengths
   3. Crane reduction factors for special lifts or operations
   4. Clearances around the crane and along the pick travel path
4. Inspect the rigging:
   1. Does the rigging have proper identification?
   2. Does all of the rigging have known working  load limits?
5. Evaluate the weight of the load and consider the capacity of the rigging.
6. Evaluate the load’s center of gravity and plan the rigging to be balanced about the CG.
7. Select/measure the appropriate sling angle.
8. Consider any side or angular loading.
9. Provide rigging protection from for any sharp corners, edges, or abrasive surfaces.
10. Provide a tag line to control the load.
11. Consider special environmental conditions (excessive heat, corrosivitity, etc.).
12. Clear all personnel from suspended load path.
