padeye load
Apply to member
supporting
padeye. For other
member the load
factor is 1.0
Apply to padeyes, connections
to structure and spreader frames
or beams considering torsion
effect for 45/55 sling load
distribution
Check stresses for padeye, structure members to be
within allowable limit? Without 1/3 increase in allowable
stress by AISC
