The main advantage of excavator is that the hydraulic system and kinetic energy ratio in the same unit of time compared with the same type of excavator to do more work outstanding cost-effective advantages. What do you know about the items that excavators need to check before working? The following Henan slip excavator Xiaobian Xiaobian collated some information to share with you, hoping to help you through the reading of this article.

1, the rotation part


(1) The rotary drive device should work smoothly and should not overheat.


(2) The rotating platform should rotate smoothly, there should be no block, impact, rotating gear mesh, lubrication should be good.


(3) The oil level of the gear oil of the rotary reduction device should reach the oil level mark height.


(4) There should be no abnormal noise, overheating and leakage when the walking drive motor and the rotary drive motor work.


(5) The operating speed of the working device should be normal, and the sinking amount of the piston rod of the working device hydraulic cylinder should not be greater than 100mm/h.


(6) The control valve should be able to effectively control the left and right rotation of the rotating platform, the extension and retraction of the bucket rod, the rise and fall of the boom and other actions.


2, the working device inspection provisions:


(1) The boom, bucket rod and bucket should not be deformed, cracked or welded.


(2) The teeth of the bucket should be complete and complete and should not be loosened.


(3) The connecting shaft pins of the boom, bucket rod and bucket should be well lubricated, and the shaft pins should be fixed firmly.


3, braking and... Device inspection regulations:


(1) When the walking pedal is in a free state and the walking joystick is in a neutral position, the walking brake should automatically be in a braking state.


(2) After releasing the control lever of the multi-way reversing valve, the control lever should automatically change its position, and the working function of the excavator should be stopped;


(3) The pilot control switch rod should work reliably and effectively.
