Excavator off-chain, commonly known as off-chain, means that the track is separated from the track formed by the driving wheels, supporting wheels, guide wheels, and sprocket wheels.
As excavators often work in harsh environments, and the crawlers are parts that directly contact the ground, when the working ground is bad and the operation is improper, it often leads to disconnection.
In addition, improper operation will also cause the excavator to disconnect
Seven reasons for disconnection can be used as a reference.
1. The tensioning cylinder is leaking oil, working abnormally, and the track tension is too loose.
2. Improper adjustment of the clearance between the guide wheels, brackets, and wear-reducing plates.
3. Walking on the rock for a long time, the track is not evenly stressed, the track pin is broken, and the chain is worn and broken.
4. There is foreign matter between the guide wheel and the crawler frame, and improper operation, resulting in uneven force on the crawler, and eventually the crawler will be strained and broken.
5. Leakage of the oil seal of the sprocket wheel causes serious wear of the sprocket wheel, and can also cause the track to fall off the chain.
6. The screws on the guide wheels are missing or broken.
7. Excessive work load for a long time and serious wear cause the chain to derail.
