| Abstract: | In this article the disabled loose-leaf of the slope elevator was investigated and there are some measures taken, such as crack analysis, metallographic analysis and material analysis. So the conclusion was drawn that the fracture attributed to fragileness rupture. Approximately, there are three reasons as following, the pitiful impact ductility of elevator's material, the original defects and the decarbon layer of elevator's surface. |

| Keywords: | fragileness ductility defect decarbonate layer |
