Do a good job in the maintenance of the excavator bottom track roller can properly extend its service life, in the daily construction process, it is necessary to avoid the heavy wheel wading in the summer, soaking in the soil and other situations, if it can not be avoided, it is necessary to carefully clean up the mud and sand after the stop work, you can support the unilateral track, and then with the strength of the drive motor to get rid of impurities. In winter, the seal between the heavy wheel and the shaft is afraid of icing, scratching and causing oil leakage, so pay special attention to this aspect.
