What is the function of excavator carrier roller?

The carrier roller is located above the X frame, which is used to keep the straight line movement of the track chain.

If the carrier roller is damaged, the track chain rail cannot keep straight.

The carrier roller is a one-time lubricating oil. If there is oil leakage, it can only be replaced. During working, it is necessary to avoid the carrier roller soaking in mud for a long time. Usually, keep the inclined platform of X frame clean, and do not let too much mud and gravel pile up to prevent the rotation of the carrier roller.
