Why can't excavators use regular bolts casually?
No matter how old you are, no boy can refuse an excavator!
The strength of China's infrastructure construction is beyond doubt, and the technology components of Chinese control excavators are well-known to everyone. As an important engineering machinery equipment in construction projects, there is no need to say much about the necessity of excavators. So, what should be paid attention to when using various types of excavator screws on vibration control machines?
What are the consequences of using ordinary bolts directly on excavators? Many people have a mentality when maintaining excavators that if the screws of a larger excavator come loose, they will come to the original equipment for replacement. However, for some small bolts and screws that must be replaced, it is easy to find a replacement of the same model. It is precisely because of this mindset that excavators continue to experience frequent malfunctions even after maintenance. The main reason is that many excavator screws used on excavators have very high performance and quality requirements, and currently, randomly finding sonic bolts on the market may not necessarily meet specific practical needs. If there are many parts of the excavator that require the use of "fine buckle" bolts, electroplated copper bolts, and copper bolts, if bolts are directly used instead, it is likely to cause many problems such as loosening and difficulty in disassembly. Some bolts may also be stretched and deformed when used, and it is surprising that the excavator does not malfunction if they are repeatedly used.
In addition, there are some specialized bolts on excavators that have strict requirements for strength and ductility, which require unique materials and special manufacturing processes, such as engine crankshaft bolts, cylinder ginger bolts, connecting rod bolts, flywheel bolts, nozzle peripheral anchor bolts, etc. For example, the bolts connecting the excavator walking motor to the drive teeth are used in special places, and can be easily damaged if not careful. Therefore, high-strength bolts are needed to ensure the stability of tightening. In summary, every small bolt in the excavator is very important and must not be replaced casually.
