Lifting Jet Engines: Rigging Cranes for Complex Objects

Click For Summary
SUMMARY

When rigging a crane to lift complex objects like jet engines, it is essential to utilize engineering drawings to determine the weights of subsystems such as turbines and bypass fans for accurate calculations. Lifting should always occur through designated hard points on the structure rather than the center of mass to ensure stability. The lifting point should ideally be positioned above the center of mass to prevent unwanted movement during the lift, as the object will seek to realign itself to its center of mass if lifted incorrectly.

PREREQUISITES
  • Understanding of rigging principles and crane operation
  • Familiarity with engineering drawings and weight distribution calculations
  • Knowledge of load balancing techniques
  • Experience with identifying hard points on complex structures
NEXT STEPS
  • Research proper rigging techniques for lifting heavy machinery
  • Learn about load calculations and weight distribution for complex objects
  • Study the principles of balancing moments in rigging scenarios
  • Explore safety protocols and regulations for crane operations
USEFUL FOR

Engineers, rigging specialists, crane operators, and safety professionals involved in the lifting and transportation of heavy and complex machinery such as jet engines.

Ok If you had a complex object, like a jet engine and what to rig a crane correctly to pick it up, what would be a good procedure on how to go about this? Let's say you had access to the engineering drawings and such, and could thus get approate weights for subsystems(turbine, bypas fans, etc etc) for proper calculations.

You never pick up an object through its center of mass. Always through several hard points on the structure where it can handle the load.

But to answer your question, assume basic shapes and just balance the moments.
 
it's a good idea to lift the object through a point which is above the center of mass. if you lift it from a point not exactly above it, the object would move and try to find a new point of center mass.
