For an excavator, most of the maintenance cost is spent on the undercarriage system, so it is necessary to know some methods, such as selecting the appropriate undercarriage, training operators, etc., to reduce the undercarriage replacement cost. Generally speaking, there are controllable and uncontrollable factors that affect the service life of the undercarriage, and we can only take corresponding measures against the uncontrollable factors.
According to different machine weights and uses, the most suitable track width should be selected. Generally speaking, the narrower track has a good grip, while the wider track has a large contact surface with the ground, so it can adapt to more ground conditions. Many experts suggest that it is best to use the narrower track, because the wider track needs a stronger power transmission system, which will lead to higher fuel consumption and wear on the mini excavator undercarriage parts when turning.
The application of the heavy equipment undercarriage parts should be considered before selecting the grousers. When laying pipelines, it is best to choose single or double grousers. Generally speaking, if the track has more grousers, it is more suitable for long-time work.
There are various types of shoes, and it is necessary to consider whether the conditions are suitable when choosing. ES shoes generally have stronger track gears, which improve the durability and service life of machines, but will cause some penetration problems and increase the weight of top roller excavator. The shape of grousers also affects the running of the machine. The thinner the grousers, the smoother the running.
If a project requires the front idler excavator to keep running, it is best to use lubricating chain, because lubricating chain can form an oil film and reduce the friction of undercarriage system. For some projects that need to deal with torsion type, it is best to choose dry track. The inner master lock hitch pin and bushing of this track are very easy to wear, so the design of rotating bushing can be increased, and the rotating bushing track can adapt to reverse operation better and hardly produce wear.
If the track is too tight, it will cause great wear of the undercarriage track of the machine, so it is best to set the track tension properly and check it regularly, so that the track tension can adapt to the work of the machine better.
Dust and other debris on the dresser dozer undercarriage should be cleaned regularly. If it is not cleaned in time, the space between the undercarriage and the track will be reduced, resulting in greater wear and tear.
After the machine has been used for a period of time, the heavy equipment undercarriage of the machine should be inspected completely, and the worn or old parts should be repaired or replaced. The main inspection items include drive motor, drive sprocket, idler and roller, track bolt and so on.
If you want to replace chains, sprockets or idlers, it is best to replace them in complete sets. If the new case undercarriage parts of the machine are matched with the old ones, the service life of accessories will be reduced.
Operators should have a deeper understanding of control movements, change different control movements skillfully, and reduce the operations that will increase contact stress between components.
The operator should balance the direction of the machine evenly and ensure the position of the driving motor. When working on some slopes, correct operation can reduce the wear of the construction machinery parts.
