| Abstract: | The tearing reason of 30 loader is analyzed. By analysis to the force which causes the danger to the cross section of the lifting ann, under the condition of not changing the components joints and part general availability of the work implement, the area of the cross section is enlarged, the safety coefficient at the dangerous cross section is improved, the material cutting and welding technology is improved, therefore breakage of lifting ann is avoided. |

| Keywords: | loader lifting ann break improve measure |
