If using cranes of different rated capacities, the crane with the larger rated capacity: - Should be hooked a distance closer to the loads center of gravity. Hoist ropes that are not rotation resistant must have a design factor of: - 3.5 to 1. Backward stability on a R/T crane could be a problem when the crane is working: - Over the side at a minimum radius. It is important to inspect rotation resistant wire rope more frequently because: - Internal damage will occur more frequently. It is important to know when lubricating wire rope that the lubricant must: - Not hinder visual inspection.
