The traveling part of excavator is composed of supporting sprocket, supporting wheel, driving wheel and rail link, etc. . After running to a certain time, these parts will appear a certain degree of wear and tear. However, if the daily attention to maintenance, you can avoid the future "excavator leg major surgery. ". It can save you a lot of money and avoid the delay caused by the maintenance. The way to reduce the wear on the working part of the excavator: The first point: If you walk on the sloping ground repeatedly for a long time and turn suddenly, the side of the chain link will contact the side of the driving wheel and the side of the guide wheel, to increase wear and tear. Therefore, as far as possible, should avoid walking in sloping areas and sudden turn. Straight line travel and big turn, can effectively prevent wear and tear. The second point: if part of the supporting sprocket and supporting wheel can not operate the state to continue to use, it may cause the wheel wear off, but also may cause rail chain joint wear. If found unable to run the wheel, must be repaired immediately! In this way, other malfunctions can be avoided. The third point: Supporting Wheel, supporting sprocket installation bolts, track plate bolts, drive wheel installation bolts, walking pipe bolts, etc. , because the machine after a long time working easily because of vibration and loose. For example, if the crawler plate bolts loose in the case of continued operation of the machine, or even lead to a gap between the crawler plate and bolts, which will lead to cracks in the crawler plate. And the gap may also increase the track and rail link between the bolt hole, leading to the failure to tighten and must replace the track and rail link serious consequences. Bolts and nuts should therefore be regularly inspected and tightened to reduce unnecessary maintenance costs.
