The four wheels and one belt in the excavator chassis: supporting wheels, sprocket wheels, drive wheels, guide wheels, and crawler tracks are all vulnerable parts of the excavator. If you don't pay attention to maintenance and care, they are easily damaged.

Today I will share with you the maintenance methods of the supporting wheels in the excavator chassis. Machine owners, please save the code!

1. Try to avoid soaking the track wheels in muddy water for a long time.

2. After completing work each day, prop up one side of the crawler and drive the travel motor to shake off the dirt, gravel and other debris on the crawler.

3. In winter, the supporting wheels must be kept dry, because there is a floating seal between the outer wheel of the supporting wheel and the shaft. If there is water, it will freeze at night. When the excavator is moved, the floating seal will come into contact with the ice and be scratched, causing oil leakage.

Note: Damage to the track rollers can cause many faults, such as deviation and powerlessness. If you need to replace the track rollers, it is recommended to replace all the track rollers on one side. If you mix old and new track rollers on one side, the new track rollers will be easily worn out.

As one of the four wheels in the chassis of excavators and bulldozers, the main function of the track wheel is to support the weight of the excavator and bulldozer and allow the track surface to move forward along the wheel. At present, the annual market demand for this forging is large, and it is a vulnerable part in the chassis. Because it is subjected to large forces during operation, it needs to have high comprehensive mechanical properties, and its blank needs to be forged. Each track wheel is welded together by left and right half-wheel forgings. According to its working conditions, the outer surface and both end faces are allowed to be left unprocessed after forging, and only the inner hole can be subsequently machined.
