For a well designed and maintained shaft system a rope life of 100,000 cycles is normally expected. Hence values from the table for slopes of 30 degrees and more are “adequate” subject to the comments already made about the neglect of wear life. The table demonstrates that the use of a constant Factor of Safety (in this case equal to 8) leads to high risk of poor rope life when the incline slope is less than 30 degrees and to uneconomic selection (the rope is larger than necessary) when the slope is larger.
