Both ends of the boom cylinder is connected to the frame and boom tilt, bearing width is too small.
2、装配调整间隙不当，导致侧面磨损严重
Adjust the gap to improper assembly, leading to serious side wear.
3、动臂缸下端排料处沉积料积累和动臂缸下端外侧磨损
Sedimentary material accumulation and the lower boom cylinder boom cylinder discharge at the lower end of the outer wear.
4、沉积料积累严重，旋转摩擦力较大
Severe accumulation of sedimentary material, large rotary friction.

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。
Increase the bearing width, the width of the support rod diameter generally 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。
During assembly, adjustment pad to ensure full use of the boom cylinder with the gap at both ends of the rack and boom with 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。
Improved nesting structure, increasing the discharge opening from the board of H1 and tilt angle α, reducing the backlog blanking, blanking conducive to the smooth natural discharge; increasing the lower end of the boom cylinder connection with the host nesting distance H2, in order to facilitate discharge large 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。
Use the instructions provided on the accumulation of material removed regularly request. After the improvements, the rod bent not happen again.
