The engine is the power source of the excavator, and diesel oil is mostly used. The motor can also be used in a convenient place. Since excavators are generally constructed in a relatively harsh environment, it is inevitable that the crawler will move, damage, break and other faults. What are the reasons for the damage of the crawler?
1. when the excavator carries out earthwork works on uneven roads, the operation site is generally uneven. Under such terrain conditions, if the crawler excavator travels the wrong route, the weight of the body will tend to be local, and the local pressure will increase, which will cause certain damage to the crawler and cause dynamic problems.
2. improper operation and control during turning when the excavator is turning, the crawler on one side walks and the crawler on the other side does not move, resulting in a large rotating movement. If the crawler is blocked by the raised part on the ground, it will get stuck on the crawler on the rotating side, and the crawler is easy to be damaged.
3. the excavator can not drive on the road for a long time like a car. The operator should pay special attention to the fact that the crawler excavator can not travel for too long, which will not only cause great damage to the crawler, but also affect the use time of the equipment. Therefore, the movement of the excavator must be controlled.
4. when the crawler excavator is working or moving, some gravel or soil will enter the crawler. If it is removed in time before walking, the gravel will be squeezed between the drive wheel, guide wheel and crawler as the interest rate belt rotates. Over time, the crawler of the excavator will move and the chain rail will be broken.
5. the excavator is not properly parked. The crawler excavator must be parked in a flat place. If it is uneven, the excavator's crawler will bear uneven stress, and the crawler on one side will bear large weight, which is easy to cause the crawler to be pulled or cracked due to stress concentration.
