Method for reducing wear of walking part of excavator

2020-07-23
The walking part of the excavator is composed of supporting chain wheels, supporting wheels, driving wheels and rail links, etc. After running for a certain period of time, these parts will wear to a certain degree. However, if daily maintenance is the only thing that needs to be done, it will take a little time for proper maintenance to avoid future 'major excavator leg surgery'. Save you considerable maintenance funds, and can also avoid delays caused by maintenance.
The first point: If you repeatedly walk on the inclined ground for a long time and suddenly turn, the side of the rail link will contact the side of the drive wheel and the guide wheel, thereby increasing the degree of wear. Therefore, you should avoid walking and leaning on slopes as much as possible. Straight travel and large turns can effectively prevent wear.
The second point: If it continues to be used in a state where some of the carrier rollers and rollers cannot run, it may cause the rollers to wear off and at the same time may also cause wear on the rail links. If you find a roller that does not work, you must repair it immediately! In this way, other failures can be avoided.
The third point: mounting bolts for track rollers and carrier wheels? track shoe bolts? driving wheel mounting bolts? walking piping bolts, etc., because the machine is easy to loosen due to vibration after a long time of work. For example, if the machine continues to run when the track shoe bolts are loose, it may even cause a gap between the track shoe and the bolt, which in turn may cause cracks in the track shoe. Moreover, the occurrence of gaps may also increase the bolt holes between the track and the rail link, resulting in serious consequences that the track and rail link must not be tightened and the track and rail link must be replaced. Therefore, the bolts and nuts should be regularly inspected and tightened to reduce unnecessary maintenance costs.
