Walking excavator by carrier wheel, supporting wheels, wheel and rail links etc., when running at a certain time, these parts will appear a certain degree of wear.

However, if the daily maintenance of the idea, as long as a little bit of time to carry out the appropriate maintenance, you can avoid the future of the big operation of the legs of the excavator". To save a considerable amount of maintenance funds, and also to avoid the maintenance of the delay caused by the time limit.

Modern excavator

The first point: if a long time repeatedly suddenly turned to walk on steep ground and side, will make the side rail chain wheel and guide wheel and the contact, thereby increasing the degree of wear. Therefore, it should be avoided as far as possible in the inclined belt walking and suddenly turn. A straight line and a large turn can be effectively prevented.

The second point: if some care and support sprocket wheels running status can not continue to use, it may cause partial grinding wheel wear, but also may cause track chain. If you find a roller that is unable to work, you must repair it immediately so that you can avoid causing other failures.

Third points: roller, sprocket, track bolt mounting bolt and a driving wheel mounting bolt, walking piping bolt, because the machine after long time working easily because of vibration loosening.

For example, if the crawler board bolts loose in the case to continue to operate the machine, and even lead to the gap between the crawler board and bolts, and then lead to the track plate of the crack.

Moreover, the generation gap may also increase the bolt hole track and rail links between the serious consequences of fastening must not replace the track and rail links. Therefore, the bolts and nuts should be regularly checked and implemented to reduce unnecessary maintenance costs.
