2、er of gravity hardware requires review and consideration of lifting method to ensure a level and safe lift.Description of Driving Event: In the Integrated Equipment Assembly IEA dolly ring removal process, it was noticed that the inner ring has no lifting point, two 4-ft web straps were used to lift
3、 it; one was choked around the apex, and the other was shackled to it (which seems superfluous if two web straps are going to used).Lesson(s) Learned: If the IEA inner ring has no lifting point, it would better to lift about the center of gravity of the ring. This can be accomplished by using one we
