4. due to eccentric shaft, pin damage or expansion sleeve loose, so that the direction of the trough wheel with heavy dislocation;
5. The base of the base of the basic rigidity of the poor level of tolerance or collapse, rack beating;
6. Fixed, movable jaw plate after tooth wear to continue to use;
7. brackets, elbow pad of the selection of substandard, can not afford a huge impact, crusher in the strong impact, the brackets did not occur self-protection, resulting in frame cracking
