If the excavator is compared to a person, the walking parts of the excavator are equivalent to human legs. Therefore, the traveling parts of the excavator are very important components, and we need to carefully maintain them to ensure their good work.
1. Check and adjust front wheel alignment
The front wheels of the excavator incline outward too much and toe in is very small, which is easy to cause eccentric wear during walking The important reason is that the front axle bearing and shaft sleeve are deformed due to impact, or the fastening device of the front axle telescopic sleeve is loose, which will change the front wheel positioning angle and cause abnormal wear Therefore, in the application process, always check whether the positioning angle of the front wheel is appropriate, and adjust the toe in
2. Accurate control and careful driving
When the excavator is walking, it should be careful not to cross obstacles at high speed and not to turn sharply under heavy load; Drive at a low speed on high and uneven roads and try to avoid emergency braking; When climbing with load or driving on muddy roads, do not make the walking system slip seriously
3. Pay attention to operating conditions
When the excavator is operating in low-lying areas, it is necessary to try to avoid vehicle entrapment. After vehicle entrapment, the method of traction and pushing shall be adopted to eliminate it. The method of increasing the throttle (emitting black smoke) shall not be used to make the walking system idle
4. Timely cleaning
After the completion of excavator operation, the sludge on the wheels and tracks shall be removed (cleaned) in time to keep the walking system clean, especially the oil seal device on the end face of the roller shall be cleaned, inspected and maintained in time In addition, be careful not to let oil, acid, alkali and other corrosive substances contaminate the rubber tire
5. Maintain normal track tension
Before applying the excavator, carefully check whether the track tension is consistent? If the track is too loose or too tight, it is easy to cause accelerated wear of track shoes, track shafts and wheels, so it is necessary to maintain appropriate tension.
