Stress analysis of welded-type crane sheaves by measurement and the numerical analysis of the unloader traversing sheave is described. Stress of the welded joint between the web and the boss is concentrated on the loading side of the web due to the radial clearance of the roller bearing, which is well computed with gap elements by FEM. The fatigue equivalent stress during the unloading operation can be obtained from the stress range distribution which is modeled by the normal distribution. Variation of the stress range is mostly determined by the dynamic response factor of the wire rope.
