Reasons for excavator off-chain

1. Off-chain caused by failure of the tensioning cylinder.


At this time, you should check whether the tensioning cylinder has forgotten to butter, and see if there is any oil leakage from the tensioning cylinder.

2. the off-chain caused by severe track wear.

If it is used for a long time, the track must be worn, and the wear of the links, chain barrels, and other components on the track can also cause the track to delink.

3. Dechaining due to wear of the chain protector.

Now almost all excavator tracks have chain protectors, and the chain protectors can play a very important role in preventing delinking, so it is also important to check whether the chain protectors are worn.

4. Disengagement caused by wear of drive motor ring gear.

For the drive motor ring gear, if the wear is severe, we need to replace it, which is also an important reason for the off-chain of the excavator.

5. Dechaining caused by the damage of the supporting sprocket.

Under normal circumstances, oil leakage from the sprocket oil seal will cause serious wear of the sprocket, which will cause the track to be off-chain.

6. Off-chain caused by damage of guide wheel.

When looking at the guide wheel, make sure that the screws on the guide wheel are not missing or broken. The slot of the card guide wheel is not deformed.
