Tips for using Excavator
——Chassis
The working environment of Excavator is poor.，The use and maintenance of chassis parts is very important.，Xiaobian based on years of Excavator service experience，Share the use and maintenance tips of chassis parts with you from the following parts：
01
Chassis Parts Usage Tips
Track link
The excavator is tracked.，The traction of the motor is very strong during traveling，Because each section of the track link has a certain length，The drive wheel is in the shape of a gear，Therefore, when walking,，There will be a polygon effect.（When the entire track shoe is parallel to the ground，Small driving radius，When one side of the shoe is in contact with the ground，Large driving radius，Resulting in inconsistent travel speed of excavator），Thereby generating vibration.。When the operation is improper、The road surface is uneven.、Change in tension、There is a lot of soil on the track link.、The resonance of the caterpillar link will be caused by the traveling of foreign bodies such as sand and stones.，Thus causing the track link of the track to jump.，Accompanied by sound.；When it is serious, it will accelerate the wear of chassis parts.，It can also cause track derailment.。
Roller、Track and guard plate、Drive wheel、Drag chain wheel
【Worn roller and chain rail】
【Shoe and ground wear】
【Worn drive wheels】
Excavator roller、Track and guard plate、Drive wheel、The material of the carrier roller is alloy steel added with wear-resistant material to be forged and cast.，Although there is a heat-treated protective film on the metal surface,，But if you don't do it right、Improper tension of track or existence of foreign matters，Any protective metal film will wear off.，Final Accelerator Roller、Track and guard plate、Drive wheel、Wear of the upper roller。
Floating oil seal
Excavator travel motor and reducer、Roller、The inside of the carrier roller requires gear oil for lubrication，Travel motor and reducer、Roller、Floating oil seal of carrier roller is a kind of non-contact seal.，Its function is to prevent oil leakage.，No oil leakage under normal condition。But when there's dirt outside,、Excessive accumulation of foreign matters such as sand and stones will enter the oil seal and cause damage to the oil seal.，Causing an oil leak；The oil temperature will rise if the excavator travels for a long time.，The floating oil seal is aged，Eventually, an oil leak occurs.。
Idler and tensioner cylinder
The excavator idler and tensioner cylinder assembly is the device that maintains the standard tension of the track；Tension varies with operating conditions and foreign matter in the chassis，To maintain standard tension，Be checked and adjusted regularly。When there is oil stain on the surface of the idler and the tension cylinder、Sand and stone、Soil and other foreign matters need to be cleaned.，Otherwise, it will cause oil seal failure and oil leakage.。

Chassis Parts Maintenance Tips
① By the end of each day's work，Support the excavator track on one side 30 above the groundcm，Traveling at a high speed, repeatedly running back and forth, and supporting the side track，Loosen or dislodge foreign objects by vibration。
② Check the chassis parts regularly，When there are too many foreign objects on the chassis part、Abnormal operation or every 250HAnd then clean up，So that that service life of the chassis part is prolon。
③ Wear goggles when cleaning foreign objects.、Hard hat，And keep a safe distance.，Prevent damage caused by splashing of gravel and silt。
Note：Foreign objects that cannot be removed by vibration，An auxiliary tool such as a drill or screwdriver can be used for stripping；If necessary, use a cleaning device to remove foreign matter from the chassis part。When the chassis parts are abnormal and have no effect after cleaning，Please contact the dealer for handling.
Finally，Please refer to the digger.《Driver's manual》Operation and maintenance of excavator，Properly use and maintain the chassis parts。
Chassis Parts Use and Maintenance Reminder
1.Avoid sharp turns、Support the car to turn、Walk at high speed on rough road；
2.Avoid driving the excavator for a long time；
3.Check whether the chassis parts are abnormal before work every day，If there is any abnormality, handle it in time.；
4.Check the tension of the track before work every day.，Press《Driver's manual》Adjust to the specified standard；
5.Clean the foreign matters on the chassis parts at the end of each day，Prevent excessive wear and oil leakage of chassis parts。
