Daily maintenance of excavator chassis Mini Excavator Parts
Nowadays, excavators can be seen everywhere on construction sites. In order to ensure the normal construction, it is necessary to maintain the excavator, in order to reduce the occurrence of failures and improve the efficiency of the excavator. Of course, excavator chassis also needs to be maintained. Although the chassis part is some iron guy, but it is also crucial for excavators, and it is easy to ignore. Chassis needs to maintain nothing more than support heavy wheel, support sprocket wheel, guide wheel, drive wheel and track. Let’s talk about how to maintain the four wheels.
First roller maintenance should avoid long-term immersion in the mud, and many sites are all of mud, and in general the site will be a perennial water to prevent leakage of dust, so lead to basic on the site are all kinds of dirt, when we were at the completion of a certain job, should be regularly to those who cling to clean up dirt in the above, Especially in winter, we must pay attention to keep the support wheel dry. Support wheel damage will cause a lot of faults, such as: walking deviation, walking weakness.
The sprocket is located on the X frame, which is an important tool to ensure that the excavator can walk in a straight line. If the sprocket is damaged, it will lead to the deviation of your excavator. The sprocket needs to be injected with lubricating oil. If oil leakage is found, a new sprocket needs to be updated. So usually we should pay more attention to the above cleaning, the large piece of soil after the completion of the work are easy to clean up, to avoid blocking the sprocket after solidification.
The guide wheel is located in front of the X frame. It is composed of the guide wheel and the tensing spring. It is an important tool to keep moving forward in the walking process of the excavator. If the guide wheel is broken, it may cause friction between the chain rails, and the tension spring will also suffer a lot of friction impact, so the guide wheel is also very important to maintain.
The driving wheel is located at the back of the X frame, which is directly fixed on the surface of the X plus without shock absorption function. If the driving wheel walks in front of the X frame, it will not only have abnormal wear on the driving ring and chain rail, but also have adverse effects on the X frame, and the X frame may have early cracking and other problems. We should always open the drive wheel guard plate to clean the inside of the stolen goods, to avoid excessive accumulation in the process of walking wear motor tubing, and corrosion of tubing joints.
The crawler is mainly composed of crawler plate and chain rail section. The crawler plate is divided into strengthening plate, standard plate and lengthening plate. The reinforcement plate is mainly used in the mine condition, the standard plate is used in the earthwork condition, and the extension plate is used in the wetland condition. The wear of the track plate is serious in the mine. When walking, the gravel will sometimes be stuck in the gap between the two plates. When it comes into contact with the ground, the two plates will be squeezed, and the track plate is prone to bending deformation. The chain rail link is driven by the gear ring in contact with the gear ring for rotation. Track overtension will cause early wear of chain rail, gear ring and guide wheel. Therefore, according to the different construction road conditions, it is necessary to adjust the track tension.
