1.加大支承宽度，一般支承宽度为活塞杆直径的1.2～1.5倍。
1 increased bearing width, generally supporting rod diameter width of 1.2 to 1.5 times.

2.在装配过程中，充分利用调整垫保证动臂缸两端与机架和动臂的配合间隙与对中性，提高调整垫材料耐磨性能。
2 in the assembly process, take advantage of the boom cylinder to adjust the pad to ensure that both ends of the frame and boom with the gap and neutral, adjust the pad material to improve wear resistance.

3.改进排料结构；增大排料板的开口距离H1和倾斜角度α，减少落料的积存，利于落料顺利自然排出；增大动臂缸下端与主机连接处排料的距离H2，以利于大尺寸石料的排出。
3 Improved nesting structure; increased nesting plate and tilt angle opening distance H1 α, reducing blanking accumulation, which will help smooth blanking natural discharge; increasing the lower end of the boom cylinder connection with the host nesting distance H2, in order to facilitate the discharge of large-size stone.

4.使用说明书规定对积存料定期清除的要求。改进后，活塞杆未再发生弯曲。
4 Use the instructions provided on the accumulation of material periodically clear requirements. After the improvements, the rod bent not happen again.
