The term off-chain is often tied to bicycles and some equipment that requires a chain, but today we are going to talk about the off-chain of the telescopic excavator arm. Some people will be curious about where the telescopic arm comes from. But if you take this question to ask your friends who understand construction machinery, they may give you a different answer.
Before we understand this problem, we want to look at the design of the appearance and structure of the excavator, because the excavator is often equipped with various booms and attachments during operation, and it has to withstand very large pressure and load. It is also a walking tool. It is different from a car. Two crawlers are used for walking to increase the contact area with the ground. However, these two vital crawlers need chains to drive. Therefore, if people are not paying attention, it will cause the excavator to disconnect.
So do you know under what circumstances will the telescopic excavator arm get off the chain? If it is used for a long time without maintenance, it will cause excessive wear and tear of the track and cause the chain to fall off. If the chain is still disconnected during maintenance, it may be a problem with the tightening cylinder, because the tightening cylinder is not greased or appears. In addition, the telescopic excavator arm is generally equipped with a chain protector, which in itself is a kind of protection chain. If it is off the chain, you can also check whether it has any problems. In addition, failure of the drive motor and the oil seal of the sprocket will also cause the chain to fall off.
If your telescopic excavator arm is out of chain during use, be sure to check the above points. Excluding these basic problems can bring great convenience to your use.
