There are many reasons for the excavator to go off the chain. In addition to the accidental off-chain caused by the crawler entering stones, impurities, etc., there are also the deformation of the crawler, the failure of the gear ring and the chain protector, which can cause the excavator to go off the chain.
In addition, there are also improper use of the excavator. Cause it to go off-chain, so now summarize what causes most people's off-chain:
First, the off-chain caused by the failure of the tightening cylinder. Many people do not remember whether the cylinder is buttered or not. This will easily lead to off-chaining during work. Also, check whether there is oil leakage in the tightening cylinder. The words are dealt with immediately.
Second, whether the track wear is very serious. If it is used for a long time, the track must be worn very seriously, and if the chain part on the track is severely worn, it is very easy to cause the track to come off the chain.
Third, the gear ring of the drive motor is seriously worn, which can be said to be the cause of most people's off-chain. The wear is serious and they are reluctant to replace it, which leads to frequent off-chain. Don't let yourself change the chain frequently to save money.
Fourth, do not often check whether the screws on the guide wheel are missing or broken. Is there any modification to the slot of the card guide wheel?
Off-chain is a very troublesome thing. The above points need to be paid attention to frequently. If your excavator is often off-chain, you need to pay attention to the above points. Of course, there are other possibilities. It is a good thing to check frequently, so as not to delay the construction.
