Do not forget fatigue. Lifting lugs see highly cyclic loading with a significant impact component. Extractive industries like mining and lumbering beat the living hell out of mechanical equipment--they tend to judge the worth of equipment by the weight, not how cleverly they're engineered. Maybe you already know this, but it never hurts to repeat it.
