Why is the excavator off chain? How to avoid?Made in America track roller
The track of the excavator is derailed, commonly known as the chain. Once engaged in digging machine for several years, the most afraid thing is to lose the chain! There are many reasons for derailment, but most chains are too loose and the tension decreases. This principle is easy to understand. It is similar to a bicycle. If the chain is too loose and too long, it is particularly easy to fall off.
For a excavator chassis, the chain tension is normal and the sag is also within the appropriate range. Therefore, it is not easy to drop the chain in normal use. However, the tighter the chain is, the better. Too tight the chain will lead to excessive resistance, serious loss of walking power, weakness of walking and other symptoms.Made in America track roller
The chain above is
It’s a little loose, but it’s also within the normal range. It’s just a metaphor. If the chain is too loose, first check the tensioning cylinder. If the cylinder still has stroke, you can tighten the chain by buttering. Generally, it can be observed from the guide wheel sliding rail whether the guide wheel can continue to extend outward and whether the tensioning cylinder still has stroke. If there is room, just butter it. If the tensioning wheel has been fully extended and the chain is still loose, check the wear degree of the chain rail shaft pin. If the wear is too large, the chain will become longer, and the excessively long chain tensioning oil cylinder can not maintain the tension of the chain. The chain rail can only be replaced, and the chain rail plate can not be replaced.
In addition, the damage of the guide wheel (guide wheel) bearing will also cause the chain to be too loose. One of the reasons for derailment is that the bearing of supporting pulley is damaged, the bearing of supporting roller is damaged, the chain guard is damaged, and the driving teeth are worn too much. The entry of foreign matters such as stones into the chain rail during work is also one of the reasons for derailment. Try not to walk backwards when driving at ordinary times. It is more likely to fall off the chain when turning. Walking backwards means that the driving wheel is in the front, while the guide wheel needs to be in the front when it is normal. This should also be noted! When the soil on the site is soft, the chain can be loosened a little, and the chain track can be rotated in time and space to clean up the excess soil.Made in America track roller
