The primary damage cause of crane is fatigue damage. The fatigue life prediction method determines service life and the design of the crane. So it is very important to study the prediction method of fatigue life. This paper summarize the existing prediction methods of fatigue life systematically. The research of fatigue life was involved in mechanics, metal material, vibration mechanics, fracture mechanics, fatigue theory and so on, which made a difference between the predicted result and the actual life. The development of the fatigue life evaluation methods are promoted because of the application of new skills, but it still needs more learning.
