Crawlers are widely used in construction machinery and equipment, and are part of the walking device of crawler excavators. Since excavators are generally constructed in a relatively harsh environment, it is inevitable that the track will be loose, damaged, broken, etc., so what are the reasons for the damage to the track?
1. Driving on uneven roads
When the excavator performs earth and stone works, the working site is generally uneven. In such terrain conditions, the crawler excavator walks on the improper route, the weight of the machine body will tend to be local, and the local pressure will increase, which will cause local crawlers. Certain damages, loosening problems will occur.
2. Improper operation when turning
When the excavator is turning, the crawler on one side is walking and the crawler on the other side does not move, and there is a large rotation movement. If the crawler is blocked by the raised part on the ground, it will get stuck on the crawler on the rotating side. The track is easily strained.
3. Long time walking operation
Excavators are not like cars that can be driven on the road for too long. Operators need to pay special attention. Crawler excavators cannot run for too long. This will not only cause great damage to the crawlers, but also affect the service life of the equipment. Therefore, The excavator's movement and walking must be mastered at one degree.
4. Failure to clean up the gravel in the track in time
When a crawler excavator is working or moving, some gravel or soil will enter the track. If it is removed in time before the walking, the gravel will be squeezed on the driving wheel and guide wheel as the interest rate belt rotates. Between the track and the crawler, over time will loosen the track of the excavator and cause the chain track to break.
5. Excavator parking is not reasonable enough
The crawler excavator must not be parked in a vague manner. It must be parked in a flat place. If the height is uneven, it will cause uneven force on the crawler of the excavator. The crawler on one side bears a large weight, and it is easy to cause the crawler to be pulled due to stress concentration. Broken or cracked.
